Executive Summary Introduction This Municipal Waste Management Strategy (WMS) for Walsall sets out the strategic framework for the management of municipal waste arisings in the Borough over the next 20 years. It has been prepared with reference to Government guidance on the preparation of municipal waste management strategies1 and Government policy2. In February 2004 Walsall MBC undertook a public information and consultation exercise on the content of the draft WMS. The respondents overwhelmingly endorsed all parts of the Council’s preferred option – a Balanced Recycling, Composting and Recovery Strategy for Municipal waste. In delivering this strategy, the Council intends to: 1. Introduce waste reduction, education and awareness programmes 2. Significantly increase rates of recycling and composting over the short to medium term; 3. To sustain and further enhance rate of recycling and composting over the medium to long term 4. To recover value from waste that is not recycled or composted, over the medium to long term (and thereby enhance the waste recovery achieved by recycling and composting). Walsall MBC will review and update the strategy periodically (at least every five years). Background In developing this draft Municipal Waste Management Strategy, Walsall MBC considered a variety of options for the future management of wastes generated by the community. The chosen way forward is a balance of recycling, composting and waste recovery. This can achieve all the targets set of Walsall MBC while at the same time delivering future flexibility to adapt and change to technological developments. The balance of recycling, composting and recovery aims to deliver a high level of sustainability through adopting waste management hierarchy and maximising the diversion of waste from landfill. Waste minimisation and education to reduce waste growth is a primary priority. In addition recycling and composting would be maximised in the short to medium term. Over the longer term waste that is not recycled or composted would be treated so as to recover value (energy) from it. The central principles of this strategy are to: 1. Introduce waste reduction, education and awareness programmes 2. Significantly increase rates of recycling and composting over the short to medium term; 1 Guidance on Municipal Waste Management Strategies. DETR, March 2001 2 Waste Strategy 2000 England & Wales.

Deliver points 1 to 4 above in a way that offers Best Value to the community of Walsall. Delivering the Strategy Walsall MBC had embarked on a series of activities designed to deliver improvements in service provision and initiate the implementation of the draft waste management strategy. The main actions for the forthcoming years are summarised below. It should be noted that estimated tonnages stated, in relation to the targets set out for each of the following tables, are based on projections using a 3% reducing curve for household arisings and a 2% reducing curve for municipal waste arisings (referenced to audited base data for year 2002/03). This assumes that waste minimisation measures to be employed by the Council are effective during the time period covered by this municipal waste management strategy. Year 2004/5- No Statutory Targets. Service actions and improvements for 2003/04 are set out in Table 1.1. The delivery of the target of 16% recycling for 2003/04 is assumed to have been achieved (1 st quarter returns report 16% recycling and composting rate). However the Council recognise that this target may only just be met and therefore significant improvements are required to not only consolidate but improve upon this target if the 2005/06 are to be met.

Background Information 2.1 Introduction As a Unitary Authority, Walsall Metropolitan Borough Council (Walsall MBC) has the responsibility for both waste collection and waste disposal. As a Waste Collection Authority (WCA) and Waste Disposal Authority (WDA), Walsall MBC has a number of statutory obligations. These include: A duty under Section 45 of the Environmental Protection Act 1990 (EPA 1990) to collect household waste and, if requested, commercial waste within Walsall. Responsibility under Section 53 of the EPA 1990 to arrange and provide places for the disposal of waste collected by Walsall MBC within its function as a WDA. A duty under Section 89 of the EPA 1990 to ensure that relevant land is, so far as practicable, kept free of litter and refuse. A requirement under Section 49 of the EPA 1990 to prepare and update plans for waste recycling. Before sustainable waste management solutions can be developed for Walsall MBC, a thorough understanding is needed of how much waste is generated and how it is currently managed. Other factors such as the socio-demographic characteristics of the area, local and regional planning policies, and statutory and legislative drivers will determine the range of suitable waste management solutions. This Chapter summarises the background conditions and potential future developments that will influence the management of municipal waste in Walsall. 2.2 Socio-demographic Profile 2.2.1 Location Walsall MBC encompasses an area of 9970 hectares (38.5 square miles) and, unusually for the West Midlands, half the land area is open use and over a fifth is used for agriculture (Figure 2.1). Within this Urban/semi-rural spilt are the five towns of Aldridge, Brownhills, Darlaston, Bloxwich and Willenhall. The Borough is one of contrasts, as it also has large industrial areas to the west, and 40% of the Council area comes within the top 10% of the most deprived areas of the Country. The Borough also contains an extensive area of green belt along its north eastern margin. This area contains several areas of importance for nature conservation as well as wildlife corridors and heritage trails. Other areas of importance for conservation are located throughout the Borough although these are typically of limited geographical extent. Walsall MBC area is bordered by the adjacent Local Authority areas of Wolverhampton, Sandwell and Birmingham (Figure 2.1) which together comprise the Black Country. Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 6 Figure 2.1 Location of Walsall MBC 2.2.2 Regional Geology The geology of the West Midlands region is dominated by sedimentary deposits including the Coal Measures (Middle Coal Measures in the vicinity of Walsall), Keuper Marl and Sandstone. Igneous rocks although not widely found, outcrop in isolated exposures at places throughout region. Some of these are commercially extracted. Historically economic reserves of coal, clay, marl, sandstone, sand and gravel have been exploited to support industrial development in the West Midlands. The residual voids and quarry’s have been used extensively for the landfilling of wastes although limited unused capacity now remains in the Region. 2.2.3 Housing and Population The official Walsall MBC figure for population in 2003 is 253,345. The population of Walsall in 1991 was estimated at 263,400 and, as with other areas of the West Midlands, the population has been subject to decline. Based on 1996 projections, the population was expected to be around 252,800 in 2006, a decrease of 4% in 10 years. However the reported 2003 figure is not far off this, indicating a greater population decrease than expected. Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 7 Figure 2.2 Population Projections Walsall Population Projection 1996 Based Projections 265.00 Thousands 260.00 255.00 250.00 245.00 240.00 235.00 230.00 1996 (base) 2001 2006 2011 2016 2021 Year The community of Walsall has solid multi-cultural characteristics with 13.6% of the population comprising ethnic minorities. The largest ethnic groups are people of Indian and Pakistani origin, comprising 5.3% and 3.8% respectively. There are approximately 105,329 dwellings in Walsall giving an average occupancy level of approximately 2.4 persons per household. Despite the fall in the Borough’s overall population the number of households is anticipated to rise. A trend of increasing single and lone parent household occupancy is expected to increase with time. The housing stock in Walsall is dominated by the provision of semi-detached and terraced properties. The revised deposit draft Unitary Development Plan 20023 required that new housing stock will continue to be provided despite a fall in population and there are a number of developments that are facilitating this. Projections contained within this plan suggests the provision of an additional 10,100 dwellings between 2001 and 2011 (approximately 505 per year). The type of property has a significant impact on the quantities and types of waste generated. Generally detached and semi-detached dwellings have gardens and as a consequence can generate significant amounts of green wastes during the growing season. The distribution of housing types in Walsall is shown in Table 2.1. 3 Walsall Metropolitan Borough Council (2002).

Five percent of Walsall’s population was claiming unemployment benefit in March 2002, compared to a national average across the United Kingdom of 3.3% (figure 2.3).

In 1991 17.7% of the population owned 2 or more cars. 2.2.6 Employment Levels of unemployment in Walsall (6.9%) have fallen since 1999 although these continue to remain high compared to the national average (5.0%). Particular groups adversely affected by Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 9 acute unemployment include ethnic minorities, young people and men in general. Details of employees by sector are shown in Figure 2.4. Figure 2.4 Employment by Sector in 1995 Employment by Sector Percentage of workforce 40 35 30 25 20 15 10 5 0 Agriculture Utilities M anufacturing Construction Sector Distribution, hotels and restaurants Transport and communications Commerce Public Other services 2.2.7 Transport Infrastructure The Borough is well served with communications being on the a network of motorway links, including the M6 towards Birmingham and London, the M5 towards the South West and with the M40, M42 and M54 also in close reach. These motorways are primarily fed by dual carriage A class roads. Many of the main primary roads and motorways are congested. Birmingham international airport (with the Eurohub passenger terminal) is within 50 minutes travel by car and 40 minutes by train, and provides international access. 2.2.8 Relevance of Socio-Demographic Characteristics The implications of these socio-economic characteristics for developing a long-term waste management strategy are summarised below: The historical trends and future projections of population decline and increases in household numbers, along with a trend towards smaller households and single occupancy, have important implications on future household waste arisings in Walsall. Walsall comprises a predominately urban area which means that the majority of household waste arisings are concentrated in a defined area. This should make waste collection and kerbside collection systems comparatively efficient. A high number of multi-storey flats will impact on waste collection and recycling practices in some areas. Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 10 The nature of the housing and the socio economic status of the occupants dictates the compositional analysis of the waste. This is important in the implementation of segregation schemes for recyclates. Unemployment levels in the Borough suggest that the additional social benefits arising from the development of waste management infrastructure, in terms of job creation, is an area of importance for Walsall. 2.3 Waste Arisings in Walsall MBC 2.3.1 Municipal Waste Arisings For the period 2002/2003 Walsall produced 150,221 tonnes of municipal waste. This equates to a municipal waste generation rate of approximately 593 kg per person per year. Municipal waste comprises the categories listed in Table 2.2. A breakdown of these arisings is shown in Figure 2.5. This shows that the predominate source of municipal waste within the Borough is household waste that is collected solely for the purpose of disposal. However significant quantities of waste are collected by the Council for disposal from trade and industrial premises. Table 2.2 Municipal Waste Categories Household waste collected from households for disposal Bulky and Garden waste collections from households for disposal or recycling Separate collections from households of other wastes for disposal or recycling Recyclate collected from households Civic Amenity site wastes for disposal Civic Amenity wastes for recycling Bring site wastes for recycling (bottle banks etc.) Clearance of fly tipped Wastes Municipal Parks and gardens waste Street Cleansing Wastes and litter Commercial and industrial waste collected by Local Authorities Waste from schools Gully waste Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 11 Figure 2.5 Breakdown of Municipal Waste Arisings in Walsall Municipal Waste Aisings 2002/03 10% Collected H/hold 3% CA 10% Recycled & composted 13% 64% Drainage & Rubble Trade 2.3.2 Household Waste Arisings Household waste can be defined as all municipal waste excluding rubble, commercial and industrial wastes, gulley and fly tipped wastes, collected by a Local Authority. Household waste therefore includes all waste and recyclables collected directly from domestic properties, as well as waste received at the civic amenity sites and at bring facilities. In 2002/2003 the total quantity of household waste handled by Walsall MBC amounted to 131,323 tonnes, of which 14,962 tonnes was recycled or composted, generating a combined recycling and composting rate of 11.4%. Household waste arisings in Walsall equate to an average of 24.9 kg per household per week, 1.29 tonnes per household per year, or 518 kg per person per year. The national average household waste arisings for 2001/02 was approximately 522 kg per person per year as reported by Defra .

It can be seen that there was a significant rise in municipal waste arisings between 1998/99 and 1999/00 (14.6%), and this rise is wholly attributable to the increase in household waste arisings. Between 1999/00 and 2001/02 a steady growth in household waste was observed. This increase has been reversed between 2001/02 and 2002/03 with a slight decrease in household arisings of 1.4%. Averaged over the past five years the significant increases in household arisings evens out to give an average annual increase of 3.84%, and only 1.9% if only the last three years are considered. When attempting to establish trends it is important that data are compared consistently year on year, and that comparisons are made like for like. There is clearly a lot of movement in Walsall’s’ arisings figures, with large increase in either household waste arisings and even a small decrease in overall municipal waste arisings for some years. The large increase in household waste arisings, and consequently municipal arisings as well, in 1999/2000 was due to a significant rise in the collected household waste stream (bin collection). However, as certain parts of the waste stream are not recorded separately, for example civic amenity wastes and bulky collections, it is not possible to conclude exactly where this substantial increase occurred, and consequently it is not possible to hypothesise explanations as to why such a rise occurred. As historic data is not recorded in enough detail to research explanations for such movements, year on year comparisons can not be made with confidence. However it is clearly apparent that the overall trend for waste arisings is one of a positive increase, and for this strategy average figures for the period are used Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 13 Table 2.4 Annual Percentage Increases in Waste Arisings, 1998/99 to 2001/02 Year % increase in Household Waste Arisings* % increase in Municipal Waste arisings* 1998/99 -1.08 -2.10 1999/2000 14.63 9.55 2000/01 1.5 -0.93 2001/02 5.61 2.13 2002/03 -1.4 0.58 * Compared to previous year .

Four compositional studies were conducted over the course of a year, designed to incorporate seasonal variation effects. Each study comprised sorts of waste samples for two areas: Area 1. Pelsall, Sheffield and Bloxwich. These areas were provided with a brown bin for the segregated collection of garden waste. Area 2. Walsall and Darlaston. These areas do not have a separate brown bin and garden waste is consequently collected in the residual waste for disposal. The same areas where used for all four surveys. The research was undertaken to identify, 1. The performance of Walsall MBC brown bin scheme 2. The attitudes of households within Walsall MBC on issues regarding recycling, composting and waste management 3. The composition of waste within Walsall MBC, illustrating seasonal variations. A summary report4 details the findings of each waste composition survey and the household attitude survey. An overview of the waste composition survey results is discussed briefly. When the survey was undertaken, there were no kerbside collections for dry recyclables. Table 2.6 shows the average waste composition in Walsall during the period 2002/3. It is important to note that this composition relates to the material collected in the residual bins of both areas. The figures do not take account of the tonnage of green waste currently collected through the brown bin scheme. Nor do the figures take into account other household waste arisings such as those materials collected at bring banks or at the Household Waste and Recycling Centres. These arisings have to be accounted for when the biodegradable diversion rates and tonnages have to be calculated, and this material is presented in Chapter 7. The main materials are Paper and Card (29%), Putrescibles (19%) and Fines (12%). The proportion of fines is higher than may typically be expected when compared to a national average. This may be a reflection of the sampling and sorting methodology used. Overall, although the waste composition of Walsall is marginally different to the National average, 4 Entec (2003) Summary Waste Composition and Household Attitude Survey. September 2003. Report 07289/04/WH/03206. Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 15 (as expected given that the demographics of Walsall are not representative of the National average); the relative proportions of each of the 13 material categories are similar. For example, the dominant material categories are paper and card and putrescibles. The proportions of metal and glass are lower than the national average although this is probably a reflection of the high proportion of fines in the Walsall samples. The biodegradable content of the waste stream can be estimated using the definitions provided in Waste Strategy 2000, where biodegradable percentages are assigned to material types such as textiles and miscellaneous combustibles. Applying this approach, the biodegradable fraction is estimated to account for 61 % of the municipal waste stream in Walsall. The packaging content of the waste stream is estimated at 27 %. Although several of the areas from which waste was collected for analysis had accessible bring banks close by, these are believed to have had a negligible impact on the quantities of potentially recyclable material present in the waste stream. The results of the survey show that up to 41% (or 6.9 kg/hh/wk) of the waste analysed could potentially be recycled (depending on the materials targeted, participation rates and levels of contamination). This is consistent with the low level of recycling achieved within the Borough at this time. Parallel reports5 describe in detail the different amounts of material available in the residual waste and amounts of material practically recoverable from different kerbside collections.

However, we have included the following items within this classification: Aerosols, Paints and Oils, Batteries and Other HHW) Figure 2.7 illustrates the seasonal variation in waste composition in Walsall throughout the 12month monitoring period. Paper and Card is consistently the dominant material. There appears to be an interesting pattern with paper and card declining in weight throughout the year. The largest amount of putrescibles is noticed in the autumn period, the lowest in the winter period. Interestingly more glass was present in the autumn period. Other materials remained relatively consistent throughout the 12-month period and appeared unaffected by seasonal variation.

Table 2.4 presents the annual percentage increase in waste arisings year on year since 1998/99. Population change and housing development can be used to predict future waste arisings. Whilst the population of Walsall has declined in the last six years there has still been an increase in household waste arisings, with growth rates averaging 1.9% pa over the last three years. Walsall’s Household and Municipal waste arisings are increasing at a rate below the National Average, quoted in Waste Strategy 2000. This may be representative of the slight population decrease within the borough. Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 17 Figure 2.8 shows the sensitivity of future waste arisings growth to a range of annual growth rates between 1% and 6%. This clearly shows the deleterious impact of high rates of waste growth over a sustained period of time. For example if the household waste arisings were to increase at a rate of 5% pa then waste arisings in Walsall will double within 15 years and treble within 22 years. Figure 2.8 Projected Growth in Household Waste Arisings in Walsall 500,000 450,000 400,000 350,000 300,000 250,000 200,000 150,000 100,000 50,000 0 1%pa 2%pa 3%pa 4%pa 5%pa 6%pa 20 01 /0 2 20 03 /0 4 20 05 /0 6 20 07 /0 8 20 09 /1 0 20 11 /1 2 20 13 /1 4 20 15 /1 6 20 17 /1 8 20 19 /2 0 20 21 /2 2 20 23 /2 4 Tonnes per year of household waste Household Waste Arisings Year For the purposes of this strategy it has been assumed that there will be no significant change in the population over the period of the strategy. This is not an unreasonable assumption as population decline has not been as marked as previously predicted. Even so, the overall total housing stock is expected to increase due to the trend towards smaller households and single occupancy. One of the major influential factors inhibiting the reduction in the growth rate of waste is this trend (e.g. each household receives the same “junk mail” irrespective of the number of occupiers). The number of households in Walsall is predicted to increase by 0.4% per annum until 2011, with the average household size predicted to decrease as well. As this rate of increase is slightly less than the rates achieved over the last couple of years, it is reasonable to assume that, providing no significant changes occur in lifestyle habits, municipal waste arisings will continue to increase at similar rates to that experienced in the last two to three years (in the range of 2 to 3 percent). A commitment towards waste minimisation and reducing waste growth should be a core principle of the Walsall Waste Management Strategy. Figure 2.9 illustrates the effect of waste minimisation on waste arisings. In this figure the following assumptions are made concerning waste growth for the 3% reducing (minimisation) curve: Starting at a rate of 3 % per annum until 2005/06 Waste growth reducing over time from 2005/06 to 1% per annum by 2016/17, and Zero growth by achieved by 2023/24. Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 18 This curve is presented for comparative purposes against a sustained 3% and 2% growth curve. The comparison of these curves clearly shows the impact of waste minimisation on waste arisings over the medium to long term.

Prior to 1998 an active programme of waste education was taken to the all schools within the Borough. Post 1998 the scheme has been scaled down, with waste education taken to approximately 20 schools per year (out of a total of 120). Walsall MBC initiated a new waste minimisation programme with the distribution of a leaflet to all properties within the borough in April 2003. The leaflet entitled “Refuse Collection and Waste Minimisation Service Standard” detailed the existing policy on sidewaste and closed lids. Residents were informed that if side waste and unclosed bins were put out then the bin & associated materials would not be collected. The strict enforcement of this policy has led to a reduction the number of side waste and open bins. Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 19 Walsall MBC also promotes a local charitable organisation called Carpenters Shop which collects unwanted household furniture, and sells them at low cost to people in need within the local community. This project makes a significant contribution to waste minimisation in the Borough as the unwanted goods are reused within the community and do not enter the waste stream for collection and disposal by the Council. 2.4.2 Bring Bank Recycling There is a network of local bringing sites equipped with banks for the recycling of various materials and these are distributed throughout the Walsall area. The majority of bring sites contain multiple sets of banks for the collection of glass bottles, and cans. As many sites are subject to acts of vandalism and arson only a limited number of sites can be equipped with paper and textile banks. Bring sites are located at accessible and central areas in the Borough including car parks, shopping centres, leisure centres and schools. There are a total of 62 sites. Bring site provision amounts to an average of 1 bring bank (site) per 4086 head of population which equates to 1:1699 households. Without the coverage provided by a kerbside collection of recyclables in the Borough, community access to recycling facilities is considered to be limited. The recycling rate achieved by the bring bank network is low (about 2%) with the majority of dry recyclables being collected at the two civic amenity sites. 2.4.3 Public Waste Disposal Sites (PWD’s) There are two public waste disposal sites in Walsall, one at Fryers Road, Leamore, the other situated in Merchants Way, Aldridge. The management and transportation aspects have been contracted out to Biffa Waste Service. The sites are of a split level design and have a separate area for the deposit of recyclables (glass, paper, cans, textiles, batteries etc.) and currently accepts household waste, garden waste, DIY waste, bulky items and white goods and hazardous household waste. A number of roll-on rolloff skips are available for the deposit of waste, with separate skips for rubble, garden (green) waste, scrap metal, wood and general waste. The materials are taken to the sites listed in Table 2.7 for recovery or disposal: Table 2.7 Location of Recovery and Disposal Facilities Waste Category Arrangement Disposal/Recovery Green Waste Jack Moody, Holly Bush Garden Centre, Wolverhampton Recovery (composting) Rubble Cory Environmental (Vigo Utopia) Recovery Cardboard Kappa Recovery Scrap Metal Green Lane Motor Salvage Recovery Wood Armstong Environment Recovery General Biffa Waste Services Disposal Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 20 Biffa is responsible for the transportation of green waste to Moody’s, rubble and cardboard to Cory’s and the general waste off to the various contracted landfill disposal sites. The scrap metal and wood are collected by the appropriate contractors, the arrangement being to provide collection service within 24 hours of notification. The sites are open at the following times, only closing on Christmas, Boxing and New Years Day. Summer (1st March - 31th Oct) Winter (1st Nov - 28(29)th Feb) 8am - 8pm Monday- Friday 8am - 6pm Monday- Friday 8am - 4:30pm Saturday & Sunday 8am - 4:30pm Saturday & Sunday Access restrictions apply, with a permanent 6 ft 6” barrier across the site entrance. Provision is made for high passenger vehicles. The civic amenity sites do not accept commercial and industrial wastes, except those received under contract by the transfer station at Fryers Road. 2.4.4 Kerbside Composting and Recycling In 2002/03 22,000 properties were provided with a bin for garden green waste under the “brown bin” scheme for the full year. In that year a further 11,000 properties were provided with the service for 6 months. This year, 2003/04, sees the further roll-out of brown bins to an additional 19,000 properties, taking the overall scheme availability to 52,000 properties, just under half of the households in Walsall. The remaining 50% of households have been identified as being predominantly flats or terraced housing, with limited garden, yard or storage areas, and thus not necessarily ideally suited to a brown bin collection. There is currently no kerbside collection for dry recyclables within Walsall. However, a pilot scheme for the collection of newspapers and magazines will be undertaken between January and March 2004, and this pilot may be extended until December 2006. 2.4.5 General Waste Collection Refuse collection services are provided by the council’s in-house provider, who operate out of depots at North Walsall and Aldridge. Refuse collection Of the 150,221 tonnes of municipal waste collected by Walsall MBC in 2002/03, approximately 94,815 tonnes was collected directly from domestic properties. This waste was collected from 101,350 households using a kerbside wheelie bin collection. Properties are serviced weekly with some variation due to public holidays. Multi-occupancy properties, such as blocks of flats, are provided with large wheeled bins into which waste is delivered from the householder by chute. These properties are serviced by a mix of RCV’s and bulk loading vehicles. Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 21 Bulky Household Waste Collection Walsall operates a bulky waste collection service which is available to the residents of the Borough. This service only collects such items that can safely be loaded onto flat-beds and thus there is a limitation to the type of items this collection round can accept. If items are in good condition, arrangements can be made with the “The Carpenters Shop” or Community Transport who will collect and sell the items at low cost to people in need in the local community. 2.4.6 Removal of Fly Tipped Wastes The occurrence of fly tipped wastes within the authority is a major environmental issue for the community. The amount of waste collected annually is comparatively modest but causes significant impact on those who encounter it. Fly tipped waste is generally removed as part of the street cleaning activities. 2.4.7 Trade Waste (Commercial and industrial Waste) Walsall MBC provides a chargeable service for the collection and disposal of trade and industrial waste from commercial properties located in the Borough through the services offered by the in-house provider. Industrial and commercial premises are generally serviced by bulk loading and refuse collection vehicles on dedicated rounds. In 2001/2002, 15,098 tonnes of commercial and trade waste were collected by Walsall MBC. 2.4.8 Waste Disposal in Walsall Transfer facilities Walsall MBC has a duty to manage and dispose of the 150,221 tonnes of municipal waste collected in the Borough. Most of the waste is transported to the Fryers Road transfer station to maximise the utilisation of the refuse collection vehicles by reducing the distance that they have to travel when loaded. In this way they can spend more effective time collecting waste from households. However some direct delivery is made, with the PSE having a target of 15, 000 tonnes to be delivered in this manner. In 2002/03 the PSE achieved 9, 000 tonnes delivered directly. At the transfer station the waste is deposited by the collection vehicle and this is then transferred by mechanical front end shovel loader into bulk transport containers which transport the waste to its final disposal point. The bulk compaction transporters can carry up to 40 tonnes per load as opposed to the average 7 tonne per load for a conventional refuse collection vehicle. This method of transportation management reduces the impact of waste haulage on the road network which is already heavily utilised in the Walsall area by other traffic. Waste Disposal The majority of waste collected in Walsall is disposed of via landfill. Small quantities (8,741 tonnes delivered in 2002/2003) have also been combusted for energy recovery at the MES Energy from Waste facility located in Wolverhampton. Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 22 The recycling and composting that takes place by means of the kerbside collection and bring bank schemes results in a modest recycling rate of 11.4 % for household waste. The Council is on target to achieve 16% for 2003/04 Figure 2.10 provides a breakdown of the current methods of waste management used by Walsall MBC Figure 2.10 Waste Management and Disposal Routes used for Municipal Waste from Walsall MBC Disposal Routes for MSW in Walsall Landfill Composting Recycle Energy from Waste 6% 5% 7% 82% Disposal Contracts There are currently 5 contracts for the disposal of the municipal waste arising from Walsall MBC.

Waste Management Drivers 3.1 Introduction This Chapter provides an overview of the policy framework and key statutory requirements that impact on the development of future waste management provisions. The fulfilment of statutory and non-statutory requirements will represent an important consideration in the decision making process undertaken by Walsall MBC and the decisions concerning these will impact on the scope, duration, flexibility, and costs of the future contract(s) for waste management that are let by the Council. The main drivers that are encouraging local authorities to review their waste management systems can be grouped into three categories: European legislation and policy, National legislation and policy, and Financial. These will have a profound impact on the available waste disposal routes, waste management capacity, waste collection methods, and overall economics of waste management. 3.2 European Legislation 3.2.1 The Landfill Directive One of the most notable pressures at present is the Landfill Directive (Council Directive 1999/31/EC on the Landfill of Waste) which was agreed in Europe in 1999 and has now been transposed into UK law. This seeks to prevent or reduce possible negative environmental effects from the landfilling of waste by introducing uniform standards throughout the EU. The Directive sets ambitious targets for the reduction of biodegradable municipal waste (BMW) that is disposed of to landfill (Table 3.1). Table 3.1 National Diversion Targets for Biodegradable Municipal Waste By 2010 biodegradable municipal waste (BMW) must be reduced to 75% of the total BMW (by weight) produced in 1995. By 2013 BMW must be reduced to 50% of the total BMW (by weight) produced in 1995. By 2020 BMW must be reduced to 35% of the total BMW (by weight) produced in 1995. It is widely accepted that the introduction of such measures will result in the most fundamental changes in waste management practices experienced in the UK. The Landfill Directive and the Council’s strategic plans to reduce the amount of biodegradable waste disposed of to landfill is considered in more detail in Chapter 7. Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 25 3.2.2 Directive on Packaging and Packaging Waste The Directive on Packaging and Packaging Waste (94/62/EEC) was implemented in England by two pieces of legislation: the Producer Responsibility Obligations (Packaging Waste) Regulations 1997, and the Packaging (Essential Requirements) Regulations 1998. The first of these sets targets for the recycling of packaging waste, placing the responsibility upon those in the packaging chain. Packaging also includes the boxes and pallets used in the delivery systems. All obligated companies have to arrange for the recycling or recovery of a proportion of the packaging they handle. The EU has set 2006 targets of 60-75% overall recovery and 55-70% overall recycling, with material-specific recycling targets for glass of 60%, paper and board 55%, metals 50%, and plastics 20%. This may have the effect of encouraging producers to fund more recycling of packaging in household waste, and could have an effect on prices of materials or infrastructure. However, despite increasing targets there has been little direct effect on the recycling of packaging materials in Walsall from these regulations, as any funding put into the system by producers has not yet filtered down to the majority of local authorities. The responsibility for proof of recovery falls on those businesses handling packaging and as such into the commercial and industrial sector. Proof of compliance is achieved and proved by the issue of the Packaging Recovery Note (PRN). PRN‘s can only be issued by an accredited reprocessor. Accredited reprocessors are approved by the Environment Agency and include energy from waste facilities, which accept domestic waste. PRN's from these facilities can be issued for 19% of the household waste throughput of the plant. PRN’s can be a source of income having an intrinsic and tradable value. PRN’s generated from energy recovery are currently worth between £8 and £10 per tonne. 3.2.3 EC Regulation No 2037/2000 on Substances that Deplete the Ozone Layer Otherwise known as the Ozone Depleting Substances Regulation, it requires Member States to remove ozone depleting substances (ODS) (including CFCs and HCFCs) from refrigeration equipment before such appliances are scrapped. This applies to domestic appliances from 1 January 2002. Facilities for delivering the requirements of the Regulation are currently being introduced in the UK, so like the majority of local Walsall MBC has been forced to make arrangements for the storage of fridges and freezers until suitable facilities becomes operational. 3.2.4 Waste Incineration Directive (2000/67/EC) In 1989 two Council Directives (89/369/EEC and 89/429/EEC) were adopted to control emissions of certain pollutants from municipal waste incinerators (MWIs). These have made a considerable contribution to the reduction of emissions, however, their scope was limited to municipal waste. To fill the gaps between these Directives and the Hazardous Waste Incineration Directive (Council Directive 94/67/EC) a Waste Incineration Directive has been adopted. Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 26 The new Waste Incineration Directive addresses municipal and hazardous wastes excluded from the scope of 94/67/EC, such as waste oil, solvents and clinical waste, as well as other nonhazardous wastes. It also addressed the co-incineration of wastes excluded from the scope of 94/67/EC. The requirements of the new Waste Incineration Directive have been developed to reflect the ability of incineration plants achieve high standards of emission control to more cost effectively than previously. The Directive seeks to integrate the technical progress made in recent years in the control of incineration emissions and extend the scope of existing EC measures to combat the pollution of air, water and land caused by the incineration of wastes not covered by the Hazardous Waste Incineration Directive (HWID). It will contribute to the protection of human health and the environment by achieving its key objectives which include: To reduce substantially emissions of several key pollutants to air and control releases to water and land To provide a major contribution to the achievement of the target in the Fifth Environment Action Programme to reduce emissions of dioxins and furans from known sources by 90% between 1985 and 2005 To contribute to a reduction in releases in heavy metals in accordance with the Fifth Environment Action Programme objective of eliminating exceedances of critical loads and levels To provide a coherent methodology for the regulation and operation of nonhazardous waste incineration and co-incineration. 3.2.5 The End of Life Vehicles Directive 2000/53/EC This directive: requires that end of life vehicles can only be treated by authorised dismantlers or shredders who must meet tightened environmental standards requires vehicle producers, dismantlers, and shredders (“economic operators”) to establish adequate systems for the collection of end of life vehicles states that owners must be able to return their vehicles into these systems free of charge from 2007 requires producers to pay all or a significant part of the costs of take-back and treatment from January 2007 sets rising re-use, recycling, and recovery targets which must be met by economic operators by January 2006 and 2015 restricts the use of heavy metals in new vehicles from July 2003. Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 27 3.2.6 EU Animal By-products Regulation (EC 1774/2002) The regulation came into force 1st May 2003 and enforcing legislation in England was effective as of 1st July 2003. The Regulation categorises waste into 3 risk areas: Category 1 – Very high risk animal by-products including carcasses infected (or suspected to be infected) with BSE, catering waste from means of transport operating internationally, animals used in experiments, wild animals when suspected of being infected with a communicable disease. All Category 1 animal by-products (or mixtures containing Category 1 animal by-products) must be directly disposed of by incineration or to landfill after heat treatment. Category 2 – High-Risk animal by-products including manure and digestive tract contents and condemned meat (on-farm deaths). All Category 2 animal by-products must be directly disposed of by incineration or processed through a composting/biogas plant provided they have been rendered under pressure (133C, 3 bar) prior to entering the composting/biogas process. Category 3 – Low risk animal by-products including parts of slaughtered animals that are fit for human consumption, parts of slaughtered animals that are not fit for human consumption but do not have signs of communicable diseases and derive from carcasses that are fit for human consumption, hides, skins, hooves, horns, feathers, former foodstuffs and catering waste. Category 3 animal by-products can be processed via a composting/biogas plant without pre-treatment. Catering waste is defined as ‘all waste food including used cooking oil originating in restaurants, catering facilities and kitchens, including central kitchens and household kitchens.’ Until 31 December 2005 certain former foodstuffs can be transported and treated as catering wastes. These include: Food from manufacturing premises if it is currently catering waste (products intended to be eaten without further cooking) and Food from retail outlets if measures are taken to exclude raw meat. The treatment standard required for composting or biogas digestion of animal by-products is 70C for 1 hour with a maximum particle size of 12mm. The standard is mandatory for treatment of all Category 3 animal by-products (excluding catering waste) and Category 2 animal by-products that have been rendered. The composting must take place in a closed reactor, as the Regulation requires that there is no access by vermin. In addition, all material in the system must meet the required temperature for the necessary time. The Regulation allows for national standards to be applied for the composting of catering wastes. 3.2.7 Other European Legislation Other key European legislation which specifically affects waste management, either at present or in the future includes: Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 28 EU Directive on Waste 75/442/EEC (amended 91/156/EEC and 91/692/EEC), Articles 3, 4&5 This places a requirement on Member Sates to have a regard to the need to minimise waste, encourage recycling and waste recovery. There must also be a regard to the need to protect the environment and human health in the context of potentially polluting developments. Proposed Producer Responsibility Directives The Waste Electrical and Electronic Equipment (WEEE) Directive seeks to promote the separate collection, re-use or recycling of electronic waste. The WEEE Directive requires producers to recover 75% of goods taken back for disposal and to re-use 70% of those goods. A target for the separate collection of 4 kg of WEEE per inhabitant per year is to be achieved by the end of 2006. The final text of the Directive was ratified by the European Parliament on 18th December 2002 and is likely to entered onto the EU statute book in February 2003. Member States have 18 months to transpose the Directive into national law, with producer responsibility due to start in around March 2005. This Directive is augmented by a proposal adopted by the EU to place restrictions on the use of certain hazardous substances in electrical and electronic equipment (COM(2000)347) from 2008. Government guidance is that local authorities should consider working with producers (i.e. manufacturers and importers for electrical and electronic equipment), who will be responsible for treatment, recovery and meeting recycling targets. The community sector may also have a role to play. A proposed producer responsibility Batteries Directive will require the separate collection and recycling of all types of batteries in the EU. Current national collection and recycling rates vary significantly across Europe. The Directive aims to harmonise the very different situations in member states and sets high recovery targets. In doing so, the Directive aims to reduce the quantities of post consumer batteries entering the waste stream. Under the new proposal, targets have been set to collect 75% by weight of all spent consumer batteries and 95% of spent industrial and automotive batteries. Batteries containing mercury will be banned immediately and those containing more than 5ppm of cadmium by weight will be banned from 2008. The Batteries Directive poses a significant challenge to the UK as there are no operational collections for mixed domestic batteries at present. The Government is currently funding research into the cost implications of recycling household batteries in the UK, and a pilot scheme has started in Lancashire. European Directive 96/59/EC on the Disposal of Polychlorinated Biphenyls (PCBs) and Polychlorinated Terphenyls (PCTs) This requires that where reasonably practicable, PCB containing equipment which is less that 5 litres in volume and which is contained within another piece of equipment shall be removed and collected separately when the latter equipment is taken out of use, recycled or disposed of. The PCB containing equipment will need to be treated as special waste. The components involved consist of small capacitors in electrical equipment such as refrigerators, washing machines, cookers, and fluorescent light fittings which were manufactured between the 1950s and 1986. Hazardous Waste or “Special” Waste Legislation The Hazardous Waste List (94/904/EC) has been refined, increased in length and incorporated within the European Waste Catalogue, which is the new standard by which all waste in the EU must be defined. This means that many items which were formerly not considered hazardous Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 29 will in future be considered as such, for example much electrical equipment, and fluorescent tubes. It also sets out standards for composting, anaerobic digestion and mechanical-biological treatment, and for compost labelling, and proposes that public authorities procure the compost, particularly as a substitute for peat. Working Document on The Treatment of Biodegradable Wastes (2nd Draft) In February 2002, the European Commission issued a the 2nd draft of a working group document on the treatment of Biodegradable Wastes. This discussion document sets out proposals that could represent embryonic development of potential future EU Directive on biodegradable waste designed to compliment the requirements of the Landfill Directive. The Landfill Directive does not fix the way in which required reductions in the landfilling of biodegradable wastes have to be obtained. However, it gives a clear indication that biodegradable waste should be preferably treated via biological treatment processes such as composting and anaerobic digestion. Both the EU Council and Parliament therefore invited the European Commission to evaluate whether there was a need for a Community initiative to promote and harmonise the regulation of biological treatment systems. The working document set out a series of measures designed to enhance home composting, community composting and other forms of biological waste treatment These include the mandatory introduction of separate collection systems for biological waste for all urban areas with a population of more than 2,000 inhabitants within 5 years. The document also proposes minimum technical requirements for biological treatment processes (e.g. windrow composting) and limitations on the use of compost/stabilised biowastes related based upon specific quality standards. 3.3 National Pressures 3.3.1 National Waste Policy The National Waste Strategy for England and Wales6 was published in May 2000 and sets out the Government’s policy and vision for the promotion of sustainable waste management over the next twenty years. The document expands on information previously published in the Government’s White Paper “A Way with Waste”7, by providing additional detail on the Government’s aspirations over the short, medium, and long term and the contributions that local authorities will be required to provide in meeting the national objectives. Local authorities are required to consider BPEO (Best Practicable Environmental Option) with reference to the framework provided by the waste hierarchy and the proximity principle when making strategic waste management decisions. The National Waste Strategy reaffirms the Governments belief as expressed in “Away with Waste” and “Less Waste More Value” that Local Authorities should not resort to incineration with energy recovery without full consideration to the possibilities of recycling and composting. 6 Department of the Environment, Transport and the Regions (2000). Waste Strategy 2000. ISBN 0 10 146932 2 May 2000. 7 A Way with Waste: A draft waste strategy for England and Wales Parts 1 and 2. Department of the Environment, Transport and the Regions, June 1999. Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 30 In particular, the Governments now states that energy from waste facilities should be sized and contracts sensitively designed so as to avoid competition with recycling. Nevertheless the use of waste as fuel can produce benefits best exploited where energy from waste plant form part of integrated waste management system and are designed as a combined heat and power (CHP) system. To meet the Governments targets for waste recovery processes such as energy from waste and anaerobic digestion will need to be considered. The national waste strategy sets a series of targets for recycling and composting and recovery for 2005, 2010, and 2015. The key national targets set out in Waste Strategy 2000 are: Table 3.2 Table 3.3 National Targets for the Recycling and Composting of Household Waste To recycle or compost at least 25% of household waste by 2005 To recycle or compost at least 30% of household waste by 2010 To recycle or compost at least 33% of household waste by 2015 National Targets for the Recovery* of Municipal Waste To recover value from 40% of municipal waste by 2005 To recover value from 45% of municipal waste by 2010 To recover value from 67% of municipal waste by 2015 * Recovery means to obtain value from waste through recycling, composting, other forms of material recovery, or recovery of energy. To ensure that all local authorities contribute to achieving these targets, the Government has set statutory performance standards for recycling and composting for each local authority for 2003/04 and 2005/06. Walsalls Statutory Performance Standards are: To recycle or compost at least 16 % of household waste by 2003/04 To recycle or compost at least 24 % of household waste by 2005/06 The Government will also set statutory performance standards for local authorities for 2010 and 2015. 3.3.2 Waste Emissions and Trading Bill This Bill, which was published in November 2003,, sets the framework for a landfill allowance trading scheme and provides for the details of the scheme to be established in regulations made by the Secretary of State. Defra published the Landfill Allowance Trading Scheme Consultation Paper in August 2003, requesting responses by mid November 2003. Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 31 The current proposals are that only WDA’s will be able to hold permits. Allowances in year 1 of the scheme are to be calculated on current BMW landfill rates (assuming 2003/04 as the base year), with target year allocations (2010, 2013, 2020) to be calculated from current municipal arisings (assuming base year 2003/04). Allocations for interim years will be made by drawing a line between each WDA’s first year allocation and each of their target year allocations. The mechanism for delineating this line is yet to be decided. Permits can be banked borrowed or traded allowing authorities flexibility in the development of their strategies. However permits are not allowed to be banked for use in a target year, nor can permits be borrowed across target years. It is also proposed to cap borrowing up to 5% of the following years allowance. 3.3.3 Animal By-products Regulations 2003 (SI No. 1482/2003) Statutory Instrument 1482/2003 is the enabling regulation for England, bringing into force powers of entry and offences to allow the enforcement of the EU Regulations. Separate enabling regulations will be required, issued by devolved governments, for enforcement of the EU Regulations in Scotland, Wales and Northern Ireland. The English Regulations replaces the Animal By-products Order 1999 in England. The English Regulations enforce EU Regulation (EC) No 1774/2002 as amended by: Commission Regulation (EC) No 808/2002 Commission Regulation (EC) No 811/2002 implementing Regulation (EC) No 1774/2003 as regards the intra-species recycling ban for fish, the burial and burning of animal by-products and certain transitional measures Commission Regulation (EC) No 813/2002 on transitional measures under Regulation (EC) No 1774/2002 as regards the collection, transport and disposal of food stuffs Commission Decision 2003/302/EC on transitional measures under Regulation (EC) No 1774/2002 as regards the use in feed of used cooking oil Commission Decision 2003/321/EC on transitional measures under Regulation (EC) No 1774/2002 as regards the separation of Category 2 and Category 3 oleochemical plants Commission Decision 2003/321/EC on transitional measures under Regulation (EC) No 1774/2002 as regards the low capacity incineration or co-incineration plants which do not incinerate or co-incinerate specified risk material or carcasses containing them. The Regulations state that minimum times, temperatures and maximum particle sizes are required for composting/biogas systems as follows: Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 32 Table 3.4 Minimum time, temperature and maximum particle sizes required for composting/biogas treatment of catering waste in England8. System Minimum Temperature (C) Minimum Time at Minimum Temperature Maximum Particle Size (cm) Composting (closed reactor) 60 2 days 40 Biogas 57 5 hours 5 Composting (closed reactor) or biogas 70 1 hour 6 Composting (housed windrow) 60 8 days * 40 *During which time the windrow must be turned at least 3 times, at no less than 2 day intervals Additional conditions for the composting of catering wastes are either: 1. Meat excluded catering wastes (i.e. separation at source) can be composted (as above) and then must be stored for 18 days post treatment (does not need to be enclosed); or 2. Re-treatment Thus meat containing catering waste must be composted via a 2-composting stage process: the first composting stage must be in an enclosed system, the second composting stage does not need to be enclosed. Category 3 animal by-products (excluding catering waste) and Category 2 animal by-products that have been rendered can be composted but the EU standards (70C for 1 hour with a maximum particle size of 12 mm) must be adhered to. Raw meat or wastes from the production of products that require further cooking are considered to be animal by-products and are subject to EU composting requirements. Meat excluded catering wastes does not mean waste where meat and non-meat organics have been collected together and steps subsequently taken to remove the meat fraction from the mix. Rather it means that the meat fraction was never mixed in with the non-meat waste stream. The EU Regulation prohibits the application to pasture land of organic fertilisers and soil improvers other than manure. The English Regulations define pasture land as “land that is intended to be used for grazing or cropping for feeding stuffs following the application or deposit of organic fertilisers and soil improvers within the following periods: a) Two months in the case of pigs b) Three weeks in the case of other farmed animals. 3.3.4 Waste Recycling Payments Regulations 1992 These Regulations and subsequent amendments bring in to effect provisions made within EPA 1990 for the payment of recycling credits by WDA’s for waste recycled by WCA’s and third party organisations. The current value of recycling credit paid by Walsall MBC is Taken from ‘Draft guidance on the treatment in approved composting or biogas plants of animal byproducts and catering waste’. Defra 2003 8 Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 33 approximately £31/tonne. The recycling credit system introduced by EPA 1990 is currently being examined as part of reviews initiated following the issue of Waste Strategy 2000 3.4 Financial Pressures Financial drivers have been most apparent in landfill disposal. The present growth in landfill costs can be attributable to the stricter regulation of landfill activities, improved engineering standards, and the limited capacity of landfill void space. Landfill tax was imposed in October 1996 at a rate of £7 per tonne. The tax is a levy specifically targeted on the disposal of wastes in landfill sites throughout the UK. It has two main objectives: To ensure as far as practicable, that the cost of landfill properly reflects the impact which it has upon the environment; and To help ensure that targets for more sustainable waste management in the UK are achieved. The current rate of landfill tax is £14 per tonne (2003/04). In the Chancellors 2003 Budget the government announced that the tax will rise to £15 a tonne in 2004/05, £18 a tonne in 2005/06 and at an annual rate of £3 per tonne thereafter. This would harmonise the UK tax at average European levels by 2011. Such increases will further increase the cost of landfill and introduce financial risks for landfill orientated waste management solutions over the medium and long term. 3.5 Implications for Walsall In estimating the future requirement for waste management facilities, it is important that all the potential influences on waste arisings and management requirements are considered. The following section uses the waste projections in Chapter 2 in order to determine the tonnage of material that requires recycling and recovery in order for Walsall MBC to meet the requirements of the National Waste Strategy. The Implications of the Landfill Directive are addressed in Chapter 7. Walsall’s statutory performance standard for recycling and composting set for 2003/04 is 16% of the household waste stream. The combined rate achieved in 2002/03 is 11.4%, requiring Walsall to improve on current recycling and composting figures by nearly 50%. To meet the 24% target by 2005/6 Walsall will be required to improve upon its current rate by 2.5 times over the next three years. Table 3.5 indicates how much waste will need to be recycled/composted and recovered, based on a range of annual waste growth rates, in order for Walsall to meet the targets. Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 34 Table 3.5 Year Estimated Tonnages of Waste to be Recycled and Recovered in Walsall to meet the Performance Standards and National Targets Statutory Performance Standards Tonnes to be recycled/composted and recovered 2%pa increase in waste arisings 3%pa increase in waste arisings 3%pa reducing HH waste growth arisings Local Performance Standards 2003/04 To recycle/compost 16% of household waste stream 21,432 21,642 21,642 2005/06 To recycle/compost 24% of household waste stream 33,447 34,440 34,273 2%pa increase in waste arisings 3%pa increase in waste arisings 2%pa reducing MSW growth arisings Year National Targets National Recovery Targets 2005 To meet 40% recovery of Municipal waste 71,737 73,868 71,385 2010 To meet 45% recovery of Municipal waste 79,204 85,633 75,771 2015 To meet 67% recovery of Municipal waste 130,199 147,805 117,109 The recycling rate that can be achieved in a local authority is dependant upon a number of factors including waste composition, type of collection receptacle provided, the frequency of collection, the support programme available to maintain public participation, the demographics of the district etc. Walsall recycled and composted 14,962 tonnes in 2002/03. To make the 16% target the council will be required to compost and recycle an additional 6,407 if arisings increase at 1.7% per annum (national average). Using the data from the recently conducted compositional survey, the quantity of dry recyclables and compostables in the collected waste stream can be identified. Table 3.6 shows the recycling tonnage of recyclable categories for Walsall MBC for 2002/03. (This table excludes bring bank recycling and recycling on the civic amenity site). Waste composition survey data can often be misinterpreted when calculating the amount of material available for recycling from collection round waste. Kerbside recycling schemes rarely target all of the material available and therefore overestimating the amount available for recycling. For example, all dense plastics are not targeted, due to issues such as market availability and therefore only bottle plastics are requested. However, bottle plastics i.e. PET, HDPE, PVC. only account for around 32% of dense plastics in Walsall MBC. A revised calculation of the recycling tonnage available is shown in Table 3.7 in relation to materials targeted by current collection systems and market availability within the UK. It must be recognised that these may be subject to change as markets and technologies develop and legislation evolves. When introducing a kerbside recycling scheme, it is unlikely that 100% of households offered the scheme will participate and will divert 100% of their potential material available, into the collection receptacle provided. Table 3.8 shows potential material available using typical materials specific capture rates and different participation levels. Table 3.9 shows the potential material available using predicted capture rates assuming household behaviour will improve. Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 35 These tables do not account for any change in technologies or markets and therefore assume that similar materials are targeted in kerbside collections i.e. bottle plastics, not all plastics; ferrous food and drink cans not all ferrous metals.

A more pragmatic view is that around 16,157 tonnes of dry recyclables (Table 3.8) are available Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 38 assuming that a 70% participation rate is achieved and average capture rates are applied to any kerbside scheme introduced. A further 3,664 tonnes of garden waste is available using the same assumptions. In 2002/03, Walsall collected 6,152 tonnes from the existing brown bin collection scheme. To meet the 2003/04 targets Walsall MBC have extended the brown bin scheme, introduced a kerbside collection pilot for 26,000 properties and have also increased resources at the HWRC’s to assist the public with segregation of materials. There are a number of ways Walsall may achieve its recycling targets for 2005/06 based on existing activities and future options of targeting different recoverable waste streams at the kerbside. Using the data in Table 3.6 and assuming a growth in household waste arisings of 3% per annum Table 3.10 illustrates how targeting different materials at the kerbside can contribute to meeting the recycling targets for 2005/06.

The above options are considered in more detail in Chapter 4. Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 40 4. Future Options for Waste Disposal Management in Walsall - BPEO 4.1 Introduction At present landfill is generally the lowest cost disposal option for waste disposal in the UK. However, as suitable sites become more scarce and as environmental standards for managing and restoring sites become more demanding, landfill costs are increasing. The predicted increase in landfill tax rates will further increase the cost of landfill disposal. The current rate of landfill tax is £14 per tonne (2003/04) In the Chancellors 2003 Budget the government announced that the tax will rise to £15 a tonne in 2004/05, £18 a tonne in 2005/06 and at an annual rate of £3 per tonne thereafter. This would harmonise the UK tax at average European levels by 2011. Changes of this magnitude pose a significant economic risk to local authorities that pursue waste management solutions that involve landfilling a substantial proportion of waste arisings. Walsall MBC currently relies heavily on the disposal of waste to landfill. Consented landfill capacity in the Black Country and the wider West Midlands is becoming depleted, however municipal waste arisings in Walsall are increasing, in 2001/02 arisings were up 2% on the previous year, however in 2003/03 arisings declined slightly on the previous year. Although the landfill reserves currently accessed by Walsall MBC have sufficient capacity (at current rates of in-fill) to serve the Borough for sometime, competition for commercial landfill capacity will reduce the accessible void space over the medium to long term. As landfill capacity within the Black Country diminishes the transportation of waste to distant landfill sites will become an increasingly likely prospect unless more sustainable waste management practices are introduced. Waste transportation will be expensive and is likely to require additional waste handling, necessitating the use of transfer facilities to improve the haulage efficiencies. The greater the distance, the greater the environmental impacts caused by transportation and the greater the financial cost. This is why the Government now requires local authorities to give full consideration to the proximity principle for the management of municipal waste. There is therefore a clear need to systematically consider the practicable options that Walsall MBC can adopt for the future management of wastes that will minimise environmental impacts, manage costs and reduce risk. 4.2 Overview of Options In developing a waste management strategy, the Council is required to looked at various ways of dealing with Walsall’s waste in the future. The four options for consideration are: Baseline (Continuation of existing situation) involves landfilling as the predominant disposal method supplemented by the existing kerbside, civic amenity and bank recycling schemes together with a small percent of arisings going to existing Energy From Waste facilities. Transfer station facilities would continue to Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 41 be required in the Borough. This option assumes that municipal waste arisings continue to grow at 2% per annum. 4.3 Option 1 (Maximised dry recycling and composting) is based on maximising recycling and composting through the expansion of the kerbside collections to a triple bin/bag/box collection system, and optimising the efficiencies of civic amenity recycling and bring bank recycling. This option requires householders to sort their waste into 2 or 3 separate receptacles for: dry recyclables, kitchen and green waste for composting, and other waste to be disposed of to landfill. Public participation in the recycling schemes would have to be increased substantially 70% by 2005/06. The residual waste would be disposed of to landfill. This option assumes the Council invests significantly in sustained waste education and minimisation initiatives. Over the twenty year horizon of this strategy these efforts are expect to yield significant reduction in waste growth. This scenario assumes a gradual reduction in the rate of waste growth from 2% per annum initially to a 0% annual increase by 2024. Option 2 (Maximum energy from waste) is aimed at maximising the recovery of energy through an energy from waste facility as the predominant treatment method. The option is modelled on existing proven mass burn technology. This is delivered in two tranches reflecting the requirement for increasing capacity as waste arisings continue grow (at a rate of 2% per annum as in the Baseline). The existing kerbside, civic amenity and bank recycling service in the Borough supplement the energy recovery from waste facilities. It will not be possible to put all arisings into the EfW plant and therefore 50% of trade waste arisings together with the arisings from drainage clearance is assumed to be directly landfilled. Option 3 (Balanced recycling and recovery) is aimed at delivering the highest level of sustainability through adopting the waste management hierarchy and maximising the diversion of waste from landfill. Recycling, green waste composting, and the composting of kitchen organic waste would be maximised with the remainder of the waste being treated by an energy from waste facility. Like to Option 1, this would require all households to sort their waste into 2 or 3 receptacles for recyclables, kitchen organic and green waste, and residual waste. As in Option 1, this option assumes the Council invests significantly in waste minimisation initiatives which, over the twenty years reduces the annual rate of increase from 2% per annum at the beginning to a 0% increase by the close of the period in 2024. Option 3 can be achieved either through collecting and sorting recyclables at the kerbside using specially designed vehicles(Option 3a), or through the collection of recyclables for sorting at a central facility, termed a Materials Recovery Facility or MRF (Option 3b). Again it is assumed that 50% of trade waste arisings are landfilled directly together with drainage arisings. Assessment of Disposal Options A Best Practicable Environmental Option (BPEO) assessment of the available options requires an informed evaluation of the economic and environmental consequences of each waste management option. Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 42 4.3.1 Economic As part of the option appraisal detailed financial models were developed for all four options. Figure 4.1 illustrates the increase in costs which is predicted when waste disposal services are transferred from the current situation to more sustainable facilities (2003). An increase in costs is apparent for all options compared with the current expenditure. All cost data are presented as a twenty year averaged cost at net present day value (NVP). All costs presented are exclusive of landfill tax and haulage charges. The waste management options that have been modelled are based upon implementing new facilities, at capacities capable of treating Walsall’s waste alone over a 20 year period, assuming either a 2 % per annum increase in waste arisings for the Baseline and Option 2, and a 2% reducing growth for Options 1, 3a and 3b. Economies of scale exist for waste management technologies i.e. larger plant capacity results in lower gate fees (£/tonne), particularly the capital intensive plant such as energy from waste/Environmentally Superior Technology Options. Figure 4.1 Projected 20 year averaged gate fees for proposed options Indicative anual cost of waste management options (20 yr average at NPV) excluding landfill tax ESTO/Enhanced Technology EfW 12,000,000 £'s/annum 10,000,000 Green Waste Composting In vessel Composting 8,000,000 6,000,000 Landfill. 4,000,000 MRF 2,000,000 Transfer Station 0 Baseline Approved by Cabinet on 12th May 2004 Option1 Option 2 Option 3a Option 3b Walsall MBC Waste Management Strategy – May 2004 43 Table 4.1 Indicative Disposal Costs of Options (excluding landfill tax) averaged over 20 year period at NPV Waste Management Option Total Disposal Cost (£/tonne) Baseline 28.77 1 34.24 2 59.6 3a 52.53 3b 55.17 Note: these costs are indicative only and do not represent accurately modelled costs The above results are based on current landfill costs and current capital and operating costs for other plant, however it is also important to consider the sensitivities of these costs to possible changes in the future. Such changes may result from new, cheaper technologies becoming available, scarcity of landfill void, increases in landfill tax, additional costs of complying with new environmental regulations etc. As a result of the Landfill Directive and the political desire to move up the waste hierarchy, the costs associated with landfilling are likely to experience the greatest changes. The landfill tax is set to increase by £1 per year until 2004. Thereafter the rate of taxation will increase by £3 per tonne per year. These rises will result in harmonisation with the average Northern European level of taxation by 2010, which is currently £35 per tonne. Options that rely on significant quantities of waste being disposed to landfill are those most sensitive to cost increases. The maximised recycling and composting option (Option 1) closely follows the increases in the landfill basecase option as they both involve a high percentage of landfilling, whereas the options which result in significant landfill diversion become more competitive over time. Large increases in landfill gate fees would not be unrealistic for Walsall to expect, as landfill capacity in the region is constrained and waste would have to be transported over longer distances involving far greater haulage costs. The sensitivity of the Options to increases in landfill taxation is presented in Table 4.2. Table 4.2 Exposure of Options to Landfill Tax Baseline Tonnes per annum to landfill Annual Landfill Tax (@ average of £35 per tonne) Option 1 Option 2 Option 3a & b 162,007 123,576 56,223 38,811 £5,670,245 £4,325,160 £1,967,805 £1,358,385 The waste management options modelled are based upon implementing new facilities at capacities capable of treating Walsall’s waste over a 20 year period, assuming either a 2% per annum increase in municipal waste arisings for the Basecase and Option 2, and a 2% reducing per annum increase for Options 1 and 3. Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 44 4.3.2 Recycling, Recovery and Diversion Targets Each Option was also assessed against the requirements of Waste Strategy 2000 in terms of recycling and recovery rates, and the Landfill Directive targets. Recycling Rate Recycling rates were calculated as a fraction of the total household waste arisings and relate to waste that is recycled through materials recycling or composting (excluding home composting). It is evident from the modelling that the performance standards for recycling and composting will require a concerted effort on behalf of the council if they are to be achieved. If targets are to be met, a kerb-side recycling programme is required to access the high volumes of recyclables that are currently disposed of by householders in their general waste, rather than being recycled in bring banks. Any scheme will require a relatively high participation rate from the early stages of the programme to ensure the targets are met. Together with the expansion of the current kerbside scheme for garden waste, and improved recycling at the PWD’s the 2003/04 and 2005/6 targets would be attainable by Options 1 and 3. However if the Council were to maintain the status quo, then the recycling targets would not be met. Figure 4.2 presents the recycling and recovery rates for the modelled options. Recovery Rate Recovery rates refer to the recycling and composting of waste, plus the use of waste in a process that recovers value e.g. generates energy (for example incineration with energy recovery or anaerobic digestion). Recovery rates are calculated as a fraction of the total municipal waste arisings. The options that involve an element of energy recovery are the baseline case, Options 2 and Option 3. The baseline case achieves a constant recovery rate of 15.9% each year, through the continuation of current recycling and composting activities and the use of Waste to Energy Facilities. Option 1 would achieve a recovery rate of 20.6% by 2005/06 through material recycling and composting without the use of an energy recovery facility. Both these options would fall short of National Recovery Targets for 2005, 2010 and 2015 if further technologies and facilities were not established. The EfW component of Option 2 achieves a recovery of 62%, contributing to an overall recovery rate of 73.6% (including existing recycling and composting activity). These rates are consistent throughout the twenty years as the scenario assumes increases in waste arisings are evenly split between recycling/recovery and disposal. Option 3 achieves the highest recovery rate, reaching 72.9% in 2005/06 and 79.6% in 2023/24. Recovery rates for 2005/06 are based on the assumption that the EfW facilities are available immediately to receive the waste, although this is unlikely to be achieved in practice if a new facility is to be commissioned. Option 2 and 3 meet all National Recovery Targets for 2005, 2010 and 2015, assuming, of course, the EfW facilities are on-line when required. Therefore, while these options may not meet recovery targets of 2005, they would exceed the targets set for 2010 and 2015. Biodegradable Municipal Waste Diversion Targets Walsall will have to reduce the tonnage of biodegradable waste disposed directly to landfill in order to meet the statutory diversion targets under the Landfill Directive. The amount of biodegradable waste that is diverted from direct disposal to landfill has been modelled, and the options assessed against the Landfill Directive targets (Figure 4.3) Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 45 Figure 4.2 Indicative Recycling and Recovery Rates Achieved by Modelled Options Landfill Directive Targets.

On the other hand, options 2 and 3 can clearly meet all Landfill Directive targets with regard to the diversion of BMW. This is due to the fact that options 2 and 3 involve the incineration of all waste that is not recycled or composted. The Waste Incineration Directive requires incinerator bottom ash to have a total organic carbon (TOC) content of less than 3%. Consequently it has been assumed that the bottom ash landfilled has an organic carbon content of 3%, which is taken to be biodegradable, thus generating a BMW landfilled for options 2 and 3. A system of landfill permits may be introduced in England to limit the amount of BMW authorities can landfill. The implementation of such a system will have significant financial implications for the future waste management options. Baseline and Option 1, which both rely heavily on landfill, as the sole or significant disposal method, would necessitate the Council purchasing additional landfill permits from other local authorities due to the Council exceeding it’s permitted level of landfill allocation. As the landfill permit allocation declines over time to meet the targets required by the Directive, the Council would have to purchase more and more permits in order to continue disposing of the waste to landfill. This would be a substantial financial risk for the Council. Options 2 and 3, however, which divert over 95% of untreated municipal waste, would result in an excess of landfill permits available to the Council which could then be traded to other local authorities. The Council’s strategic plan for achieving the Landfill Directive and the management of landfill permits is dealt with in Chapter 7. 4.3.3 Environmental The main purpose of this appraisal is to provide rational information on which of the main environmental impacts associated with each option can be examined and considered for the purpose of BPEO determination9. ‘A BPEO is the outcome of a systematic and consultative decision making procedure, which emphasises the protection of the environment and the conservation of the environment across land, air and water. The BPEO procedure establishes, for a given set of objectives, the option that provides the most benefits or the least damage to the environment as a whole, at an acceptable cost, in the long term as well as the short term.’ An analysis of the environmental impacts arising from each of the disposal options was carried out using WISARD (Waste Integrated Systems and Assessment for Recovery and Disposal), a life-cycle assessment (LCA) tool developed to assist Local Authorities with their assessments by the Environment Agency. The model evaluates the environmental burdens and impacts of waste management operations. Within WISARD a user develops various waste disposal scenarios, utilising the compositional data from surveys (Section 2.3.5) and the calculated waste arisings and flows (2.3.6). 9 Royal Commission on Environmental Pollution: 12 th Report: Best Practicable Environmental Option (1988). HMSO London Feb. 1988. ISBN 0-0-103102-5 Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 47 WISARD utilises the “avoided burden” methodology for calculating environmental burdens. For example, for recycling activities, credits are given by calculating the energy and raw materials associated with the production of that product had the recycling not been performed. Credits are also assigned to those options that generate power, as this energy production is offset against the requirement for fossil fuels (primarily coal for electricity generation). WISARD has been used to assess the environmental burden against the following impacts typically regarded as significant with regard to waste management practices: Global Warming Impacts Air Acidification Eutrophication Natural Resource Use Dioxins This assessment has focused on the recovery/disposal aspects and transportation impacts relating to collection have not been included. Option 3a and 3b are considered on the basis of tonnages recycled and therefore are the same for this assessment. Global Warming Impacts The global warming potential of a waste management system is dominated by the emissions of carbon dioxide and methane. Methane is a much more potent greenhouse gas compared to carbon dioxide and consequently a significant consideration in waste management options (in general terms landfill gas is between 40-65% methane). Thus the global warming potential of each scenario can be linked to the methane emissions, which is dependant upon the amount of biodegradable waste disposed of to landfill. As the existing situation (Basecase) relies solely on landfill disposal, it represents the worst case in terms of its global warming potential. Figure 4.4 illustrates the indicative reduction in the global warming potentials achieved by each of the modelled scenarios. The avoided CO2 and methane emissions result from recycling and waste combustion activities.

However the recycling activities and use of waste as an energy source in place of coal in Options 2 and 3, result in a reduction in the net emissions of greenhouse gases in the UK. All the alternative options suggest an improvement upon the Basecase. Acidification and low level ozone formation The principal gases that contribute to acidification include: sulphur dioxide (SO2), nitrogen oxides (NOx), hydrogen chloride (HCL), and hydrogen fluoride (HF). Figure 4.5 shows the air acidification potential of each option, expressed in equivalence of SO2 emissions. All options indicate a net benefit with regard to SO2 emissions, this is due to each option containing an element of energy recovery (from landfill gas and incineration) and recycling. Notably significant benefits are realised from both the recycling and Energy from Waste options. Benefits from the energy from waste options are clearly the result in the off-set emissions from a coal fired power station.

Emissions of volatile organic compounds (VOC’s) are the main contributors to ozone formation. Within the modelled waste management scenarios, these are emitted from landfills and are responsible for the impacts illustrated in Figure 4.6. The impact of the landfill is primarily localised to the general vicinity of the landfill. A clear benefit is identified from recycling in Options 1 and 3, and further analysis identifies this arising from the recycling of plastics and iron. Energy recovery is also an important contributing factor.

The enrichment promotes both plant growth and microbial activity and eventually results in the de-oxygenation of the water body. This can result in substantial fish kills, and an alteration to the ecology of the system. As anthropogenic activities increase the nutrient loading to surface waters (through direct discharges- sewage effluent, and surface run-off-fertilisers from farm land) so the occurrences and magnitude of this natural process escalate. Cost are not just to the eco-system, but arise from loss of amenity value, damage to commercial fishing, increase costs for water purification, and additional cost required to manage the system. Leachate from landfills is the main source of eutrophication causing nutrients in waste management. Thus the greater the diversion of biodegradable waste from landfill the greater the curtailment of this impact, as Figure 4.7 shows. Figure 4.7 Eutrophication of waters Eutrophication Potential tonnes equivalent PO43- 25 20 15 10 5 0 Baseline Option 1 Option 2 Option 3 Depletion of non-renewable resources. Our world has a finite supply of resources in terms of minerals and fossil fuels. The rate at which these resources are consumed is important when assessing the sustainability of any activity. Recycling of metals and plastic preserves both the mineralogical value of the item, as well as its intrinsic energy content (i.e. the energy consumed in production of the material). Energy from Waste Facilities produce electricity and heat that is assumed would otherwise be generated from a fossil fuel, thereby conserving that resource. Thus those options that can optimise recycling and energy recovery from the waste stream are the most sustainable in terms of resource use. Figure 4.8 shows the relative impact on resource use of the various options. Option 3, as it utilises both recycling and Energy from Waste has the greatest impact with regard to resource conservation. Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 51 Figure 4.8 Depletion of Non-renewable resource Depletion of Non-renewable Resources (yr-1) 0 -100000 Baseline Option 1 Option 2 Option 3 -200000 yr-1 -300000 -400000 -500000 -600000 -700000 -800000 -900000 Dioxins Dioxins are highly toxic, being thought to be carcinogenic at low exposure levels. The term ‘dioxins’ is generally used to refer to two groups of compounds: polychlorinated dibenzodioxins and polychlorinated dibenzofurans. Dioxins have been shown to occur ubiquitously in the environment. Their formation can arise from various industrial as well as natural activities, for example from most combustion processes (power generation, forest fires) and as by-products of many chemical processes and metal smelting, for example steel manufacture. As dioxins are so widespread in the environment, in many of the materials we use, handle and eat, they are consequently present in waste as it is collected and so they will be transferred to all downstream operations. Dioxins have been measured in compost, landfill gas and leachate, gases and residues from recycling as well as the more commonly cited waste combustion gases and ashes. The environmental impacts of dioxins are not so much dependant on the absolute emissions, but on the pathway to humans and the potential to cause harm to health. Whilst dioxins released into the air from waste combustion sources can affect humans from absorption through the lungs or from deposition onto the skin, the major route is from deposition onto vegetation, which is then eaten by grazing animals. Accumulation in the food chain is the most significant route into human intake. In this respect, dioxins in composts and in groundwater may be of greater concern to those released to air from combustion processes. Figure 4.9 shows the relative rates of dioxin emission to various media for each of the options. This shows that all options involving energy from waste generate the greatest dioxin emissions. All options have emissions to air, however in comparison to the emissions to water these are negligible. The emissions to water from the Energy from Waste facilities arises from leachate generation from the landfilled air pollution control (APC) and bottom ash residues.

Table 4.3 provides an overview of the performance of each strategy. Performance indicators include financial aspects (capital investment requirements and 20 year averaged gate fees) and environmental factors.

This option is the most sensitive to increases in landfill gate fees and landfill tax, and will become considerably less competitive in the future compared to other options that rely less heavily on landfill. This option does not meet any of statutory recycling targets or recovery targets and could not meet the statutory obligations under the Landfill Directive. The environmental burdens are largely due to the production of leachate and landfill gas emissions, which contribute to global warming, eutrophication as well as reducing local air quality. The Baseline is not considered a viable waste management option for Walsall. The diminishing current and future landfill capacity in the area, the requirements of the Landfill Directive, the obligations to meet statutory recycling and recovery targets, and the long term financial profile of this option with the added risk of landfill tax and the requirement to purchase additional landfill permits would necessitate capital investment in alternative waste treatment technologies. Option 1 The recycling and composting option would achieve a maximum recycling rate of 49% and would meet the statutory performance standard targets for recycling. However this assumes that participation rates reach 40% for dry recyclables and 35% for compostables by 2005/06, which would be a significant achievement, especially as at present there is no dry recyclable kerb-side collection. Even though recycling and composting is maximised, this Option would not enable the Council to meet Recovery targets nor meet the likely targets in biodegradable waste going to landfill. Due to the considerable reliance on landfill, this option would be sensitive to cost increases of landfill to landfill tax. It would also retain many of the disadvantages of landfilling in addition to the increased transportation and its associated environmental impacts due to the need for an intensive three-bin collection system. Integrated collection of recyclables and putrescibles with the rest of the household waste stream would reduce transport difficulties but this is likely to require considerable capital investment in new vehicles and containers. Option 1 could be a viable option for Walsall in the short term. However Walsall would be required to implement the kerb-side collection of recyclable from scratch as there is no current provision of this service anywhere in the borough. However, for this Option to meet the 2005/06 target, it is imperative upon the Council to introduce a widespread service immediately. This Option would also require further investment in treatment technologies is the medium to longer term to increase diversion and recovery rates. Option 2 The maximum energy from waste option offers several environmental benefits. It achieves high landfill diversion and recovery rates, a reduction in global warming and acidification potentials due to the displacement of emissions from the traditional power stations and a reduction in eutrophication and low level ozone formation due to the diversion of active wastes from landfill. Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 55 Option 2 will not meet any of the local statutory recycling targets, achieving a combined recycling and composting rate of 13.7 throughout the modelled period, although this Option does meet all the national recovery and Landfill Directive Targets. Option 2 is not considered to be a viable option to fulfil Walsall’s short term objectives. However, elements of this option combined with greater emphasis on recycling and composting in the short term could provide a means of meeting the Governments’ medium and long-term targets for waste recovery. Option 3 This option represents the highest level of sustainability of all options examined and is able to fulfil all government targets with regard to recycling, recovery and the Landfill Directive. The Option combines the environmental benefits delivered through recycling and recovery operations: a reduction in global warming, air acidification, lower atmospheric ozone formation and eutrophication potentials, and a reduced rate of consumption of non-renewable resources. Whilst the WISARD assessment and costing exercise has been based on EfW, other technology options such as MBT with composting, anaerobic digestion or other yet proven technologies may be utilised. It is considered to be a viable technical option for Walsall, although it is considerably more expensive than Baseline and Option 1. Cost impacts may be mitigated by developing partnerships with nearby local authorities that deliver waste management facilities in a way which exploits current available capacities in the recovery sector and delivers best value. 4.4 Residual Household Waste Collection Walsall’s waste collection is delivered by the PSE (Public Sector Enterprise). Household waste is collected from properties on a weekly basis using a kerb-side collection service. The kerbside collection of garden waste in the brown bin scheme is two-weekly. If household waste arisings in Walsall were to continue to increase at a rate of 3% per annum this would result in a doubling of the quantity of households waste requiring both collection and management/disposal by 2025. This emphasises the importance of waste minimisation, which will for a core principle of the waste management strategy. The rates of waste growth in Walsall will have important technical and financial consequences for waste collection. If waste arisings per household are allowed to increase unchecked, then collection rounds will need to be adjusted to accommodate for the increase tonnage. This will mean an expansion in the collection fleet, thus increasing the overall cost of waste collection. The current household waste recycling schemes in Walsall comprise: 1. A network of bring banks distributed throughout the district 2. A kerbside collection scheme for garden waste to 52,000 households 3. A pilot kerbside paper collection scheme to 28,000 properties The kerbside collection of compostables comprises of a wheelie bin provided to designated residents into which garden material is deposited and collected on a fortnightly basis. This service is suspended over the Christmas/ New Year period, reducing this service to a monthly collection at this time of year. Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 56 4.5 Kerbside Collection Options Waste management options 1 and 3 require an expansion in the kerbside collection of recyclable and compostable materials within Walsall. This expansion requires the provision of additional or replacement receptacles (bags, boxes or wheeled bins) to enable segregation of these materials by the householder, as well as expanded collection infrastructure. There are numerous different collection options available with variations in the type of receptacle, frequency of collection, size of container vehicles etc. Moreover the acquisition or non-acquisition of a MRF will determine whether a kerb-side sort is required or not. A selection of example schemes have been modelled and these are illustrated in Table 4.4.

The systems will result in a 1.4 to 1.8 fold increase in the averaged annual waste collection costs for Walsall, compared with the situation in 2002/03. This reflects: Expansion of kerbside collection of dry recyclables Introduction of kerbside collection of compostables wastes Additional resources required to collect the growing quantities of waste Figure 4.10 Average cost per annum of waste collection systems Average Service Cost per annum 7,000,000 £'s per annum 6,000,000 5,000,000 4,000,000 3,000,000 2,000,000 1,000,000 Scheme A Approved by Cabinet on 12th May 2004 Scheme B Scheme C Scheme D Walsall MBC Waste Management Strategy – May 2004 58 Figure 4.11 Average cost per tonne of waste collection systems Cost per tonne Collected (20 year contract) 50.0 45.0 £'s per tonne 40.0 35.0 30.0 25.0 20.0 15.0 10.0 5.0 0.0 Scheme A Scheme B Scheme C Scheme D Due to the mixed nature of Walsall’s housing stock, it may not be appropriate for all households to have an identical level of service provision. The collection scheme needs to be designed to encourage and promote participation, not hinder it. For example in some areas of terrace housing, where frontage is directly on to the pavement, it may not be practicable to introduce a three bin scheme. Indeed it may not be advantageous anyway, especially if the housing generally benefits from back yards as opposed to gardens, in which case the level of green compostable waste will be negligible. Thus Walsall will have to develop collection systems that are compatible across the Borough, inclusive of all residents but reflects the different requirements that housing types demand. Thus there are numerous different collection options available with variations in the type of receptacle, frequency of collection, size of container etc. The Baseline and Option 2 may require expansion as waste arisings increase, but the fundamental underlying structure of the service, i.e. 1 240 l wheelie bin per house, will remain. 4.6 Integrated Waste Management Options Integrated waste management refers to a process that consolidates different aspects of waste management into a single cohesive system. This system can be potentially administered through a reduced and rationalised portfolio of contracts. This offers a number of potential benefits to Local Authorities and should be considered in the process of assessing options for service delivery and delivering Best Value. Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 59 Table 4.5 Advantages and Disadvantages of Integration of Waste Management Services Advantages Disadvantages Economies of scale through the use of a single contractor for outsourcing service provision A reduced range of contractors able to provide integrated services More experienced national and international contractors attracted by a larger contract Some services may be peripheral to lead contractors core business (problems in track record and understanding of some niche services) More co-ordinated Client monitoring as only one lead contractor will be involved in service provision Contractors will need good project management tools and skills Better spread and co-ordination of monitoring duties as each Contractor Supervisor could be involved in a range of services within a defined area Contract length for all integrated services will be determined by the time over which capital assets can be repaid. Where this involves major waste management infrastructure this likely to be over a period of 20 to 30 years. Greater service cohesion from collection to disposal Performance monitoring will be complex. Co-ordinated approach to street scene issues Maximised flexibility and partnership with the selected contractor will enable Walsall to respond to changing pressures on Local Authorities resulting from new EU and UK Legislation The interface between service elements is the responsibility of a single contractor which will prevent disputes Waste flows are the sole responsibility of the lead contractor More integration of recycling efforts through the kerbside collection system and at civic amenity sites Greater investment opportunities for both the Authority and Contractor through the integration of cleansing and collection into long term contracts Rationalisation of waste management facilities (e.g. facilities designed and developed to deliver several services/ functions e.g. combined vehicle depot, CA site and waste transfer stations) Increased flexibility in the Contractors use of manpower and resources (providing the contract enables this) Rationalised point of contact Commonality in reporting provisions and data collection methods Lead contractors able to negotiate savings from niche service sub contractors though scale of economies Management of sub-contractors is the sole responsibility of the lead contractor (i.e. allowing rationalised project management). More scope to demonstrate best value and continuous improvement across a range of services By combining the costs of the various waste management options with the modelled collection costs, the total integrated waste management costs can be analysed and these are set out in Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 60 Table 4.6. The following waste disposal and waste collection systems have been combined, generating five integrated waste management options IWMS Baseline- Baseline Waste Disposal Option plus existing waste collection system IWMS Option 1 - Waste Disposal Option 1 (maximised recycling and composting) plus Waste collection Scheme C (weekly residual waste collection and fortnightly kerbside collection of dry recyclables and 50% of properties on organic wastes) IWMS Option 2 - Waste Disposal Option 2 (maximum energy from waste) plus Waste Collection Scheme D IWMS Option 3a - Waste Disposal Option 3a (highest level of sustainabilitykerbside sort) plus Waste collection system B (weekly residual waste collection and fortnightly kerbside collection of dry recyclables and 50% of households on a fortnightly organic waste collection) IWMS Option 3b - Waste Disposal Option 3b (highest level of sustainabilityMRF) plus Waste collection system C (weekly residual waste collection and fortnightly kerbside collection of dry recyclables and 50% of households on a fortnightly organic waste collection). Table 4.6 Integrated Waste Management Options IWMS Baseline IWMS 1 IWMS 2 IWMS 3a IWMS 3b Waste Collection £5.0 £5.67 M £4.78 M £5.81 M £5.67 M Waste Disposal £5.5 M £5.8 M £11.3 M £9 M £9.4 M £0.2 M £0.2 M £15.01 M £15.27 M Education/Waste Min Total- excluding landfill tax 4.7 £0.2 M £10.5 £11.67 M £16.08 M Walsall’s Preferred Waste Management Option Guidance on the choice of options is given both by the Government in “Waste Strategy 2000”, the Landfill Directive, Best Value, and by the plans and policies detailed in this waste management strategy. These all indicate that waste minimisation is the preferred option for managing future waste arisings and that recycling and composting must then be maximised. “Waste Strategy 2000” states that “where energy from waste solutions are considered, the strategy should demonstrate that all opportunities for waste reduction, re-use, recycling and composting have been considered first”. The assessment of waste disposal options in this strategy indicates that maximising recycling and composting (Option 1) is a potentially cost effective and viable solution for Walsall over the short term. However in order to fulfil the medium to longer term Government recovery targets Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 61 the Council must recognise that recovery technologies will be needed for the long term targets to be met (Option 3). As a result, Walsall MBC have chosen a balance of recycling and recovery as the basis for the waste management strategy (Option 3). The central principles of this strategy will be to: 1. Introduce waste reduction, education and awareness programmes in order to constrain waste growth; 2. Significantly increase rates of recycling and composting over the short to medium term in order to meet statutory household waste recycling and composting targets; 3. To recover energy from waste that is not recycled or composted over medium and long term in order to assist with meeting national obligations; and 4. Deliver 1 to 3 above in a way which offers best value to the community of Walsall. Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 62 5. Plans and Policies 5.1 Key Achievements to Date 5.1.1 Pre-amble To meet the first national statutory target Walsall MBC is currently initiating a programme of improvements designed to radically improve the recycling and recovery rates. Although still in its infancy this programme has already impacted upon the recycling rates through simple yet effective measures. Details of achievements to date are provided in the sections below. 5.1.2 Waste Recycling and Composting In 2002/03 22,000 properties were provided with a bin for the deposit of garden green waste under the “brown bin” scheme for the full year. A further 11,000 properties were provided with a part-year service of 6 months. 2003/04, sees the further roll-out of the brown bins, to an additional 19,000 properties, taking the overall scheme availability to 52,000 properties, just under half of the households in Walsall. The remaining 50% of households have been identified as being predominantly flats or terraced housing, with limited garden, yard or storage areas, and thus not necessarily ideally suited to a brown bin collection. At the end of 2003/04, 33,000 properties will have had the service for the full year and an additional 19,000 properties, which are to be provided with the brown bin collection service in December 2003, (month 9 in the financial year) will have had the service for the latter three months of the year. A kerbside paper collection pilot will operate form January to March 2004 covering 28,000 properties across the Borough. 5.1.3 Public Waste Disposal Sites (PWD’s) Several improvements have and are continuing to be made to the two PWD sites at Fryers Road and Leamore. New signage has recently been installed, for all recyclable materials. Signs also indicate what householders can and cannot recycle. There is now additional skip provision for cardboard and all skips for final disposal are now identified in red. Staffing levels have been increased by one operative at each site. The new operative has been given the task of assisting the public to make good use of the recycling facilities and to sort and remove recyclables from the disposal skips at quieter times. It is estimated that these additional measures will increase recycling at the HWRC for 2003/04 by approximately 1,500-2,000 tonnes from those achieved in 2003/04. 5.1.4 Transfer Station Walsall’s Transfer Station occupies the lower level at Fryers Road. A new bay for segregation of transfer station waste arising from the Walsall Housing Group and other site users has been Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 63 established. Segregation will focus on rubble and metal arisings, which will be sent to the same contractors as the material from the HWRC. Estimated additional tonnages arising from this (based on 6 months operation Sept-March) are approximately 1,000 tonnes. 5.1.5 Black Country Waste Management Forum. The Black Country Waste Management Forum (the Forum) is a partnership formed between Walsall, Dudley, Sandwell and Wolverhampton councils, formed in 2001. The Forum, through Walsall MBC, have commissioned Entec to advise on the current and potential joint working of the Forum and on how the four partners can move towards an integrated management programme across the four boroughs over the short medium and long term The report concludes that current service provision differs across all four boroughs and together with the varying disposal operations, representing wide ranging levels of investment, these clearly provide obstacles to the regional integration of the service. The report recommends the establishment of a Council Members Forum with the appointment of a dedicated officer with an appropriate remit together with all parties signing up to a Memorandum of Understanding. These two initiatives would place the Forum on an established footing and allow work towards a common standard to progress more readily. The report also recommends that the Forum should develop a strategic plan with clearly defined objectives against which on-going performance may be monitored. There are clear opportunities for short-term projects that can be undertaken by the forum. The Forum has already realised some benefits through the formation of a purchasing consortium which had already signed contracts with EMR for refrigeration disposal and Aylesford Newsprint for newspaper reprocessing. The combined sale of other recyclables could also be exploited. Other short-term opportunities include addressing waste minimisation and education collectively, establishing a regional marketing strategy and publicity campaign. In the medium term there will be a requirement for increasing waste management infrastructure across the region as all boroughs adapt to meeting recycling and BMW diversion targets. Much of this infrastructure may be developed privately and may not necessarily be developed in the Borough to which the majority of capacity is assigned. It is recommended that political boundaries should not be allowed to unduly influence the siting of facilities, which may be of strategic significance to all four members of the BCWMF. It is recommended that a site identification exercise, which seeks to clarify infrastructure and site characteristics and availability across the Black Country be conducted. Such a survey would facilitate the development of appropriate infrastructure and seek to reduce uncertainty within the procurement process. The report also recommends that Walsall, together with Sandwell should continue in the development and procurement of their strategic options for the delivery of SPS’s but that there could be mutual benefit in jointly securing some of the infrastructure to meet their goals. Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 64 5.2 Best Value and Consultation 5.2.1 Best Value Performance Indicators Best Value requires local authorities to fundamentally review their services in consultation with their citizens and other stakeholders. Best Value authorities are authorised to; Challenge why the service is provided in the way it is. Compare their performance against other similar providers of the service Consults with users of the service and the local community about their views and decides whether someone else can provide the service more competitively. Waste management in Walsall is measured by a number of national performance indicators (some of which are Comprehensive Performance indicators), set by the Government. Those that are relevant to this municipal waste management strategy are as set out below: Table 5.1 Best Value Performance Indicator Best Value Performance Indicators Description Value in 2001/02 Value in 2002/03 Target 2003/04 BV82a* Household waste - % recycled 2.81 3.21 4 BV82b* Household waste - % composted 7.29 1 8.18 12 BV82c Household waste - % used to recover heat, power and other energy 4.3 6.61 3 BV82d* Household waste - % landfilled 85.66% 81.95% 81% BV84* Kg of household waste collected per head 503.63 518.35 527 BV85 Cost per km of keeping land clear of litter and refuse £96,056 £82,550 - BV86 Cost of waste collection per household £21.24 £24.90 £26.50 BV87 Cost of waste disposal per tonne of municipal waste £29.20 £28.53 £30.53 SI 281 (prev BV88) No. of collections missed per 100,000 collections of household waste 9 116 - BV90a* % of people satisfied with household waste collection 62.3 - 69 BV90b* % of people satisfied with recycling facilities 85.9 - 89 Approved by Cabinet on 12th May 2004 Notes Increase due to the expansion of the kerbside collection of garden waste The Government proposes to delete this indicator from 2002/03 This has changed to a Local Performance indicator .

The figure used in this strategy uses the definition of household as stated in DETR Guidance on Municipal Waste Management Strategies, March 2001, and relevant for financial year 2001/02. 5.3 Strategic Waste Management Policies & Objectives 5.3.1 Introduction In developing a waste management strategy consideration should be given to the adoption of a number of strategies, policies and objectives. The following policies and objectives are set out by way of example and suggestions for consideration by Walsall’s Elected Members with responsibility for waste management matters. 5.3.2 SWMP 1 5.3.3 Waste Education and Awareness Walsall in consultation with key stakeholder, such as BCWMF, will seek to deliver a programme of awareness, promotion and publicity to encourage a fuller understanding of sustainable waste management issues and practices throughout the community. Stakeholder Consultation SWMP 2 Walsall will seek to engage in a full and interactive dialogue with representative members of the community on waste management issues within Walsall. In doing so the Council will endeavour to ensure that all opinions are duly expressed and fully considered as part of any decision making process. The Council will ensure that the process of making such decisions is open and fully transparent to all in Walsall. SWMP 3 Walsall will enter into and maintain meaningful dialogue with the Environment Agency, nearby local authorities and other Agencies on the development of future waste management solutions for Walsall to ensure that the strategy and plans are both consistent and pragmatic in a Regional context. Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 66 5.3.4 Waste Minimisation and Reuse SWMP 4 Walsall in conjunction, other local authorities and other parties will encourage the reduction and re-use of waste. This will form an objective of a promotional and awareness programme focused on waste. SWMP 5 Walsall will establish a programme of waste minimisation, re-use, recycling of waste materials in respect of its own functions and the services it provides. SWMP 6 Walsall will establish a challenging series of long term targets for minimising the municipal waste it collects from the community. The Council will seek to forge partnerships with community groups and neighbouring local authorities with a view to establishing common aims and goals in this respect. 5.3.5 Recycling & Composting In consultation with the Environment Agency, neighbouring Local Authorities and SWMP 7 other Agencies and having regard to material planning considerations, Walsall will promote the development of new and existing facilities for waste transfer, recycling and composting provided that: These facilities are developed as part of integrated network to deliver Walsall’s needs and contribute to regional self sufficiency The facilities are consistent with the aims and objectives of the waste management strategy for Walsall There is demonstrable need for the facility. SWMP 8 Walsall will develop practical initiatives to support waste segregation at source in the household and encourage similar initiatives in business premises. SWMP 9 Walsall in partnership with key stakeholders will encourage recycling and composting at home and in the workplace. 5.3.6 Waste Management SWMP 10 Walsall is committed to movement towards more sustainable waste management practices. Walsall considers the progressive development of more sustainable waste management practices to be a legitimate strategic goal to be achieved over the short, medium and long term. SWMP 11 Through the implementation of the waste management strategy and future contracts, Walsall will seek to progressively reduce the amount and proportion of Walsall’s municipal waste being disposed of to landfill. In so doing Walsall will seek to divert municipal waste towards more sustainable waste management practices which lie higher in the waste management hierarchy. SWMP 12 Walsall supports the proximity principle and the concept of regional self sufficiency in respect of waste management facilities. Within these principals Walsall will endeavour to ensure that the waste produced by our community is managed and Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 67 dealt with within Walsall, or failing this the region, wherever this is possible. SWMP 13 In working towards more sustainable waste management Walsall will seek through the implementation of its strategy, to deliver statutory Government performance standards for waste management. SWMP 14 Walsall will seek to deliver continuous and demonstrable improvement in the quality, sustainability and efficiency of the waste management services it delivers. SWMP 15 Through the implementation of future waste management contracts, Walsall will encourage its future contractors to be proactive and innovative in identifying areas for delivering service improvement and achieving its core policies and goals. 5.3.7 Waste Recovery SWMP 16 In line with Government targets for waste recovery, Walsall will look to recover more value from waste as part of its waste management strategy over the medium to long term. The Council will maintain a watching brief on the technologies available for this purpose and seek to engage in partnerships with others where this can deliver the best practicable environmental option in way which is consistent with best value. 5.4 Implementation Plan to Meet the Targets In the Short-term (to 2005/06) Walsall MBC will continue to work with Dudley, Sandwell and Wolverhampton to develop the framework underpinning the Black Country Waste Management Forum (the Forum). Walsall will support the Forum in its bids to access funds where it is consistent with the Council’s strategic goals. It will also support the Forum in the development of a regional approach to the delivery of enhanced waste management services throughout the region where these implement the waste management strategies of the partner Councils and deliver Best Value. Service enhancement through the Forum is one option for implementing Walsall’s Waste Management Strategy and is to be explored. However, Walsall will be unable to deliver on its immediate SPS targets through the Forum and have developed independent plans to ensure its delivery of the 2005/06 targets. All these plans are be subject to ongoing review. Waste education and waste minimisation campaigns will be required if the Council is to meet its waste arisings objectives. Walsall MBC are to develop a programme of initiatives designed to fulfil the goal of reducing the year on year growth of household waste arisings from 3.0 % to 0% over the term of the waste management strategy. Programmes should seek to engage all parts of Walsall’s community, and will include sustained and high levels of interaction with community groups, schools and the population in general. Progress against waste minimisation goals is to be monitored In order to meet the 2003/04 statutory performance for recycling and composting the Council significantly expanded the brown bin scheme. As of December 2003 the scheme is offered to 52, 000 properties, just over 50% of all properties in Walsall. The scheme is now considered to be at saturation, with remaining properties being terraced and flats, and thus generating limited volumes of green waste. Improvements to the recycling facilities offered at the civic amenity Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 68 sites, for example the provision of bins for wood, will also assist the council towards meeting 2004/5 targets. The Council are in the process of investigating the implementation of a kerb-side collection scheme for paper, and has submitted a bid to Defra to fund a multi-material collection scheme. Contingency plans are to be considered for the implementations of such a scheme within Walsall should the Defra funding be unavailable. In addition, a paper collection pilot covering 28,000 properties commenced during January 2004. Medium-Term (beyond 2005/06) A contract (either Walsall stand alone, or through the Forum) should be tendered and awarded against the achievement of specified performance objectives designed to achieve high levels of recycling and composting. The managing authority will continually review the landfill diversion rates being achieved and the delivery of diversion targets as government policy develops, and will be able to instruct variations to the contract terms and objectives.

It requires all domestic vehicles to be partly dismantled and de-polluted prior to destruction for scrap. It also requires licensed dismantling facilities to be established and regulated. The legislation will require the removal of all fluids (engine, brake, transmission), seats and batteries from the vehicles prior to disposal as scrap metal, however the extent of dismantling of a vehicle is still unclear. At present, abandoned vehicles collected within the district are sent directly for scrap at no charge to the Council. However as scrap merchants are now required to be registered and regulated, thus incurring additional expense, it is anticipated that the likely costs of collection, treatment and disposal under the new legislation will be in the region of £50 per vehicle. 5.5.2 Construction/ DIY Wastes Construction and DIY waste is excluded from the definition of household waste and therefore the Council is not obliged to accept this waste at the two public waste disposal sites. 5.5.3 Hazardous Waste There are certain categories of household waste which are considered to be hazardous. There is currently no collection service for household hazardous wastes, although there are facilities at the public waste disposal sites for householders to dispose of certain types of hazardous wastes. A waste oil container and a locked cage for the storage of domestic chemical or hazardous waste and car batteries are located at Fryers Road civic amenity site. Procedures for other hazardous wastes including asbestos and refrigerators are detailed below: Asbestos ‘Hard bonded asbestos’ such as asbestos cement sheet, guttering and pipes is classified as ‘Special Waste’ which means that special rules apply to its transport and disposal. Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 70 Walsall MBC refer enquires and requests for the removal and disposal of asbestos to a third party. Residents can take asbestos to Fryers Road civic amenity site under a permitting system. CFCs The main source of CFCs are old refrigerators and freezers. These are either delivered to the public waste disposal sites free of charge or collected by the Council through the bulky household waste collection service for a fee. The EC Ozone Depleting Substances Regulations came in force from 1st January 2002, which requires all CFCs and HCFCs to be removed from refrigeration equipment before such appliances are recycled or disposed of. Through the Forums purchasing consortium, a joint contract was let to EMR to handle all domestic refrigeration units thus enabling each authority to fulfil its obligation under the ODS Regulation. 5.5.4 Equipment which Contains Low Volumes of PCB’s Electrical equipment such as radios and washing machines sold before 1986 may contain small quantities of polychlorinated biphenyls (PCBs). PCBs are usually contained in electrical capacitors and can cause environmental damage if buried in landfill sites. The Council is in the process of examining opportunities and measures to identify and segregate any potentially PCB items delivered to the PWD’s 5.5.5 Packaging The Producer Responsibility Obligations (Packaging Waste) Regulations (as amended) encourage re-use and set targets for recovery and recycling of packaging waste. Most businesses which handle packaging (more than £2 million turnover or 50 tonnes per annum packaging) have an obligation to recover and recycle certain tonnages of packaging waste each year, so that the targets in the EU Directive on Packaging and Packing Waste 94/62/EC can be met. The Environment Agency has a duty to monitor compliance with the regulations in England and Wales, and where appropriate take enforcement action. The Agency also operates a voluntary accreditation scheme in the form of Packaging Waste Recovery Notes, which are evidence of compliance with the packaging regulations. Currently there are no agreements, partnerships or co-operation between the Council and compliance schemes or obligated companies. Significant benefits could be achieved for both businesses and local authorities in utilising the already well established collection and disposal channels for recycling and recovery. Achieving the statutory performance targets is not dependant on the recycling of commercial waste but it would assist in attaining the national recovery targets and have the potential of generating income for the Council. A review could investigate the possibility of recovering packaging waste through the Council’s collection and disposal services. This should be done in consultation with the larger producers and users of packaging and their representative bodies. Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 71 5.5.6 Waste Electrical and Electronic Equipment Directive The proposed Waste Electrical and Electronic Equipment Directive (WEEE) covers a wide range of electrical and electronic equipment that fall within a voltage range of up to 1,000 volts AC and 1,500 volts DC. There are 10 categories of WEEE: 1. Large household appliances 6. Electrical and electronic tools 2. Small household appliances 7. Toys 3. IT and telecommunication equipment 8. Medical equipment systems 4. Consumer equipment 9. Monitoring and control instruments 5. Lighting equipment 10. Automatic dispensers The objectives of the proposed Directive are: the prevention of waste electrical and electronic equipment; to increase re-use, recycling and other forms of recovery thereby contributing to a higher level of environmental protection and encouraging resource efficiency; to improve the environmental performance of all operators involved in the life-cycle of electrical and electronic equipment, particularly those involved in the treatment of WEEE. Currently WEEE from households is either collected through the general waste collection service (small items contained in wheeled bins), collected through the bulky household collection service. WEEE collected with the normal refuse collection service is currently landfilled, and WEEE collected via the bulky service and through the PWD sites is either stored in the case of refrigerants or disposed of to landfill. Walsall already recover 4 kg per capita 5.6 Partnerships Most important to the delivery of this Strategy are strong partnerships between local authorities, relevant organisations and community groups acting in a co-ordinated way to achieve a common vision for sustainable waste management. The section describes the background to the principal partnership that is currently in place. 5.6.1 The Black Country Waste Management Forum To deliver Walsall’s waste management strategy in a way that reduces the cost to the community of Walsall and makes best use of regional resources the Council is developing partnerships with neighbouring local authorities. In collaboration with Dudley, Sandwell and Wolverhampton, Walsall MBC have formed the Black Country Waste Management Forum (BCWMF). Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 72 For a number of years there has been an ongoing dialogue and discussion around the convergence of waste management practices in the pursuit of government targets and improved service delivery. Discussions have focussed on exchanging views on best practice, seeking efficiencies through joint working and securing certain contracted services covering all of the four authorities. The BCWMF intended to provide a focus for the delivery of regional facilities and waste management solutions for Walsall MBC and its partner authorities. In particular it will be responsible for: Accessing funds from Central Government for investment in regional waste management services and waste related community initiatives; Procuring waste management facilities and services on behalf of the 4 partner Council’s (making use of the scale of economies); Rationalising the use of existing waste management infrastructure and systems in a way that enables all of the partner authorities to deliver their waste management objectives and targets. The provision of enhanced services through the BCWMF therefore may represent the Council’s preferred method of implementing the waste management strategy. However contingency plans should be developed in the event that the partnership cannot fulfil Walsall’s requirements, in the short, medium and long term. These plans should be continuously reviewed and updated as time progresses. 5.6.2 Community Groups Neighbouring authorities have linked with a number of community groups in the development of recycling and waste re-use initiatives. These schemes have been of limited impact on the overall waste management services provision. In part this has been due to the limited funding available and management structure. It is recognised that for such partnership initiatives to be successful there will be a need to ensure that such groups are set up with a view to their long term sustainability and have access to investment funds and skilled management resources.

Part 3 - Recycling Plan 6.1 Introduction The third part of this Municipal Waste Management Strategy provides the essential data required to be provided in a Recycling Plan. This requirement is set out in Section 49 (3) of the Environmental Protection Act, 1990 and paragraphs 2 to 7 below set out the Council’s suggested formal response to these legal requirements. The majority of waste management contracts held by Walsall terminate in 2005. The Council should be seeking to formulate a new integrated waste management and environmental service to commence at some point in the short to medium term future. Due to this major change, the period of this recycling plan is 2002 – 2005 only. As the waste strategy is further developed, this section should be expanded and developed to reflect council policy. Subsequent to the finalisation of the strategy, a new or revised plan will be required when the details around the delivery of the new waste management arrangements are known. 6.2 Essential Legal Requirements 6.2.1 Controlled Wastes Expected to be Collected During 2002-2005 Household waste arisings rose by an average of +1.9% for the last two years. The national average growth in household waste arisings is currently +2.7% per annum. For the purposes of this strategy it has been assumed that there will be no significant change in the population over the period of the strategy. Even so housing numbers are expected to increase, due to the trend towards smaller households and single occupancy. One of the major influential factors inhibiting the reduction in the growth rate of waste is this trend (e.g. each household receives the same “junk mail” irrespective of the number of occupiers). The number of households in Walsall is predicted to increase by 500 properties per annum until 2011, with the average household size predicted to decrease from 2.6 to 2.3. Taking all these conditions into account, the growth in household waste arisings can be expected to continue to increase at approximately 3% per year, and municipal waste arisings at 2% per year, until 2005. A fundamental element of the strategy is a commitment to waste minimisation with the aim of slowing the rate of household waste growth to 1% by 2015 and eventually zero. Calculations are based on actual waste arisings for 2001/02 Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 75 Table 6.1 Controlled Wastes to be Collected Type of waste collected 2002-2003 2003-2004 2004-2005 2005-2006 Household waste 138,200 142,346 146,617 150,282 Other Municipal waste 14,142 13,043 11,880 10,592 TOTAL 152,342 155,389 158,497 160,874 6.2.2 Controlled Wastes Expected to be Purchased During 2002-2005 The Council does not expect to purchase any controlled waste during 2002-2005 6.2.3 Controlled Waste Expected to be Dealt with by Separating, Baling or Otherwise Packaging it for the Purposes of Recycling 6.2.4 Table 6.2 Controlled Wastes to be Recycled Type of waste collected 2002-2003 2003-2004 2004-2005 2005-2006 Household waste No targets 22,775 No targets 36,068 6.2.5 Arrangements Expected to be made with Waste Disposal Contractors During 2002-2005 Walsall is a Metropolitan Borough Council and is responsible for both waste collection and disposal. The Council currently has contractual arrangements for landfill with a number of landfill sites. These are listed in Table 2.7. The Council will continue to procure landfill capacity under a series of short term contracts for the foreseeable future, whilst developing their long term solutions. 6.2.6 Plant and Equipment Expected to be Provided for Sorting and Baling Waste During 2002-2005 There is expected to be a requirement for a bulking facility / transfer station to be available as the multi-material kerb-side collection is rolled out.. 6.3 Estimated Costs and Benefits Resulting from Proposed Actions Outlined in this Plan During 2002-2005 6.3.1 Estimated Benefits Recycling and Waste Minimisation Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 76 During the period of the Recycling Plan (present-2005/06), Walsall’s recycling rate for household waste will improve from considerably from the current rate of 10%, to 24% in line with government requirements. The improvement in the recycling and composting rates are expected to reflect improved public participation in kerbside collection schemes for garden waste, paper and in future dry recyclables. To improve participation in recycling schemes it is Walsall intention to provide receptacles for the collection of recyclables at the kerb-side and through a sustained campaign of awareness raising and consultation. The message conveyed through such campaigns will also cover topics such as waste minimisation and re-use. The increased rate of recycling and composting achieved by Walsall, will reduce the Council’s financial exposure to increases in the rate of landfill tax, rising gate fees and the need to secure landfill permits. These represent an area of considerable economic risk. With the rate of landfill tax to increase by £3 per year from 2005, it is estimated that the achievement of a 24% recycling and composting rate by 2005/06 will yield a saving of £685,286 in landfill tax alone in that year. 6.3.2 Estimated Costs Detailed estimates and costs for the various recycling options should be evaluated as data from the compositional studies becomes available. It is inappropriate to advance detailed costs at this time pending acceptance of the principal points arising from this strategic review by the concerned authorities.

Part 4 - Landfill Directive: Strategic Plan to Reduce Landfill 7.1 National Diversion Targets The European Council Directive 1999/31/EC on the landfill of waste came into force in the EU in 1999 and its requirements have now been transposed into UK law. This seeks to prevent or reduce possible negative environmental effects from the landfilling of waste by introducing uniform standards throughout the EU. One of the key articles of the Directive sets a timetable for the progressive reduction of biodegradable municipal waste going to landfill. The UK national targets are: By 2010 biodegradable municipal waste (BMW) must be reduced to 75% of the total BMW (by weight) produced in 1995. By 2013 BMW must be reduced to 50% of the total BMW (by weight) produced in 1995. By 2020 BMW must be reduced to 35% of the total BMW (by weight) produced in 1995. To comply with the Landfill Directive, the Government has established national targets for recovery of municipal waste, and recycling/composting of household waste. These national targets are supported by statutory performance standards for household recycling and composting, and tradable permits to restrict the amount of biodegradable municipal waste that authorities can landfill. The initial consultation paper “Limiting Landfill” outlined a number of options, of which the tradable allowance scheme was the most popular. A second consultation document “Tradable Landfill Permits” outlined how the scheme would work. The two consultations have led to the Waste Emissions and Trading Bill. The permits will be allocated free of charge to waste disposal authorities and apply to biodegradable municipal waste (BMW) only. The permits will be tradable, allowing authorities that divert more waste away from landfill to trade their permits to those authorities that do not. In any given period an authority will be able to landfill BMW up to the level of permits held. If an authority does not require all of the permits for a particular year, then the authority will be able to trade them, although authorities will not be obliged to trade them if they do not wish to. Equally if an authority does not have enough permits to cover the amount of waste it intended to landfill, it would either have to increase its rate of diversion or purchase additional permits. Authorities may also bank or borrow allocations between years. Unlimited banking will be permitted within each interim target period. Borrowing against the following years allocations will be permitted but capped at 5% of a WDA’s next years allocation. However borrowing of allowances for use in target years and borrowing of permits across target years (i.e. from one interim period to the next) is not to be permitted. Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 79 The present view of Government is that the initial allocation of permits will equal to a WDA’s current BMW landfilled (base year 2003/04), with target year allocations based on each WDA’s percentage contributions to total current waste arisings (2003/04 base year). Interim allocations will be made by drawing a line between year 1 allocations and each subsequent target year. How this line is to be delineated is as yet undecided. The preferred means for monitoring compliance is a mass and materials balance approach, and it is proposed that the Environment Agency will undertaken this function. If the mass of BMW diverted from landfill can be measured and the proportion of BMW in the waste is known to start with then it will be possible to calculate the amount of BMW landfilled. To do this the quantity of BMW within MSW is required. The current estimated figure used by the Agency is 68%, although this is likely to change with the results of the Agency’s UK municipal solid waste analysis programme (UKMSWAP) (due to commence Autumn 2003 and report summer 2005). 7.2 Implications for Walsall Government intends to estimate the amount of BMW that each WDA landfills as 68% of their municipal arisings. However “adjustments will then be made for each WDA’s main method of diversion from landfill according to tonnages of waste recycled composted”. Taking Walsall’s 2002/03 municipal arisings of 150,221 and applying the 68% rule, Walsall’s BMW content would equate to 102,150 tonnes. The Defra guidance does not provide data on which BMW permit allocations for individual WDA’s can be calculated. However the requirement to reduce BMW going to landfill is likely to be challenging. To provide some indication of the difficulties ahead we have proceeded to calculated diversion rates based on a 68% BMW content and with targets to reduced BMW to landfill to 75%, 50% and 33% of 1996 MSW levels. 1996 data has been used as waste arising figures for 1995 are unavailable, (until the landfill tax was introduced in 1996 much of the waste management industry worked in cubic yards as opposed to tonnages). Table 7.1 provides indicative figures for required BMW diversions. The magnitude of the figures are indicative. These data are presented so that the enormity of the challenge can be illustrated. Table 7.1 Maximum BMW allowed to be landfilled 2010 BMW Allowed to Landfill 2013 2020 66,434 44,289 31,002 166,714 171,340 177,426 Required Diversion 46,932 72,222 89,647 Current BMW Diversion 12,142 12,142 12,142 Additional Diversion Required 34,789 60,080 77,505 Predicted MSW Arisings (2% reducing) Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 80 Table 7.2 gives indicative figures for the necessary diversion based on a 2%, 3% and 4% growth rates. Once again it is clearly demonstrated that waste minimisation needs to be an important feature in the municipal waste strategy. Table 7.2 Estimated Tonnages of Biodegradable Waste to be Diverted from Landfill by Walsall Council - based on the National Average BMW content of 68% Target Growth rate of municipal waste (% / year) 2% 3% 4% Tonnes BMW to be diverted from landfill To meet 2010 target 50,905 59,198 67,989 To meet 2013 target 80,232 92,992 106,918 To meet 2020 target 112,033 137,836 167,976 7.3 Strategic Plan to Meet the Targets The implementation of a landfill permit system will have significant financial implications for future waste management options. In developing this Municipal Waste Management Strategy the impact of the Landfill Directive should be a key criteria in the Council’s selection of the preferred waste management option. It is Walsall MBC plan to meet all of the targets for 2010, 2013 and 2020 by reducing the growth rate in municipal waste arisings, diverting more municipal waste away from landfill disposal by maximising recycling and composting, and also utilising Energy from Waste capacity. The Council will have to commit to moving away from landfill disposal and towards more sustainable waste management methods. If the Council does not want to exceed the maximum permitted tonnage of BMW disposed to landfill, and rely on purchasing landfill permits from other local authorities, there would result in a significant financial risk to the Council if the adopted strategy is not robust and pragmatic in its objectives. It is assumed that landfill permit allocations will decline over time to meet the targets required by the Directive, and the Council would have to purchase more and more permits in order to continue disposing of the waste to landfill. Walsall’s preferred waste management option (Chapter 4.6) is based on maximising recycling and composting, although the Council appreciates the need for maintaining flexibility over the medium and longer term. The Council will closely monitor the diversion rates achieved and will also continuously review technological developments in treatment and recovery technologies. The Council is aware of risks posed by political uncertainty to any waste management strategy. Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 81 Approved by Cabinet on 12th May 2004 Walsall MBC Waste Management Strategy – May 2004 Appendix A The Waste Hierarchy 6 pages The Waste Hierarchy - Options for Waste As discussed earlier, the different waste management options should be considered as a hierarchy of priorities. The first priority is ‘reducing’ the amount of waste produced. After reduction comes ‘re-use’ of materials to postpone entry to the waste stream. The third level of the hierarchy is ‘value recovery’ either by processing the waste to produce ‘recycled’ products, producing ‘compost’ or deriving ‘energy’ from the waste. The final option is ‘disposal’. Reduction The benefits of preventing waste being produced in the first place are that fewer raw materials and less energy are used, both in production and throughout the materials life. If we reduce the amount of waste produced, we reduce the amount of waste to dispose of, and reduce the need for alternative disposal facilities. Reuse It has been recognised that much of the waste stream is in fact a valuable resource that can contribute to a more sustainable society. There are many community-based activities that may support reuse waste in a constructive way. The principal examples of this sector are charity shops and furniture restoration workshops. Recovery of Value The Governments Waste Strategy 2000 reflects the need for the UK to improve recovery rates by specifying the following national targets for municipal waste (waste collected and disposed of by a local authority which includes waste from households, civic amenity sites, street sweepings and some commercial waste): to recover value from 40% of municipal waste by 2005 to recover value from 45% of municipal waste by 2010 to recover value from 67% of municipal waste by 2015 Include targets for industrial and commercial wastes. It is generally assumed that the most sustainable way of managing our waste is to: reduce the amount of waste that we produce look for opportunities to reuse, recycle and compost the parts of our waste that can be managed in this way finally, recovery energy from the remaining waste Walsall MBC Waste Management Strategy – May 2004 No single option is sustainable and can deal with all of the waste produced. An integrated waste management system is required using a range of technologies to recover value from the waste at a local level. Recycling A large amount of the waste stream can be recycled; that is reprocessed to produce a material for use within society, e.g. the recycling of paper to produce newsprint. The UK recycling rate is currently 9%, and lags behind that achieved in many other European countries. The householder has an important role in separating household waste. It is easy to separate paper, glass, plastics, textiles and green wastes for recycling. The household can either deliver the separate items to centrally located facilities, called “bring sites”, or to make it more convenient on the householder, recyclables can be collected the from home by local authorities in “kerbside collections”. It is the responsibility of Unitary Authorities to introduce both kerbside collection schemes and to provide bring sites. The collected material is taken to a Materials Recovery Facility (MRF) where it is sorted by material type (plastic, glass, aluminium, garden waste etc) and baled together ready for distribution to reprocessing facilities for reuse or recycling. There are two types of MRF, a ‘pre sorted’ MRF and a ‘dirty’ MRF. A ‘pre sorted’ or ‘clean’ MRF deals with recyclable materials which have been separated from the main waste stream – usually by the householder. The quality of pre sorted recyclable material is generally higher because it is less likely to be contaminated. A ‘dirty’ MRF deals with unsorted waste from the ‘black bag’ or ‘wheelie bin’ collection. The recyclable material in a dirty MRF is often contaminated making the quality poor for reprocessing facilities. A typical modern, clean MRF would probably receive segregated waste from kerbside collection schemes consisting paper, glass, metals, and plastic. The waste may sent to a number of locations throughout the UK for processing. Recent initiatives by WRAP are attempting to encourage the development of additional reprocessing facilities and markets across the UK in order to limit the movement of recyclables. The planning process for siting a MRF can take up to 2-3 years. Advantages of a MRF Disadvantage’s of a MRF Technology is proven in other European countries, and in the UK Potential transport impacts from delivery of waste and collection of recyclables Can be located close to waste source Requires some hand-sorting of waste with occupational health concerns Relatively low set up costs in comparison to other waste disposal options Significant amounts of energy consumed in the sorting process -irrelevant with respect to energy consumption of raw material Concerns are currently been raised about air quality around MRF operations Siting can be difficult because of the necessity for a warehouse building Relatively high quality of recyclables therefore attractive to reuse or reprocessing markets Savings on transportation costs possible if located near to large residential areas Walsall MBC Waste Management Strategy – May 2004 For recycling to be successful, there must be a market for recycled products. It is generally recognised that residents need to be engaged, so awareness needs to be raised and support for recycling needs to be offered to householders. It is also felt that businesses contribute significantly to the amount of waste, and could produce less and recycle more. The commercial and industrial sector account for a large portion of the waste deposited in licensed landfill sites. Composting Composting is a natural process which can be used to treat organic wastes, such as garden and kitchen waste. The waste decomposes and can be applied to land as a soil improver and to enrich nutrient content. It is estimated that nearly a quarter of all household waste is organic. and can be composted. Composting may be undertaken in the open, as it needs oxygen but more sophisticated enclosed plants are also available. Typical UK composting facilities are well managed and relatively sophisticated plants, which can process between 3,000 and 100,000 tonnes of material each year and will take approximately 18 months to construct. There are currently composting facilities available to Walsall that receive a waste stream consisting of garden waste and green civic amenity site waste. These facilities would not be suitable for waste that fall within the remit of the Animal By-products order (e.g. kitchen waste). Advantages of central composting Disadvantages of central composting Useful product – can be sold to offset costs Can produce odour and litter if badly managed and potential for liquid (leachate) runoff A cost effective solution to treat biodegradable waste Significant overall environmental benefit from composting and low energy consumption Concerns have been expressed over the effects of spores released during the process Can be a substitute to peat if used as a soil conditioner Vermin can be a problem when ‘food’ waste is included in the composting process Enclosed plants prevent odour and litter from decomposing waste A market for the compost is required to make the process viable Energy recovery After recovering value through recycling and composting, obtaining ‘energy’ from the waste is the next step in the hierarchy. Many European countries integrate incineration with energy recovery plants with their composting and recycling programmes. There are several established methods for producing energy from waste. Landfill Gas The degradation processes of landfilled materials releases gases, predominantly methane and carbon dioxide. The landfill gas can be recovered and utilised as a fuel. As the biodegradable content of landfill wastes is reduced, (as a result of the Landfill Directive) so the volumes of gas produced will also reduce. This may result in the recovery of landfill gas becoming more impractical and uneconomical. Walsall MBC Waste Management Strategy – May 2004 Incineration with Energy Recovery Incineration is the most common form of energy recovery from waste in the UK and worldwide. There are currently 13 incinerators operating in the UK, and 16 in various stages of planning and construction. There are no incinerators currently operating in Walsall, although incineration plant are operating in the neighbouring Black Country Boroughs of Wolverhampton and Dudley. Waste is combusted at high temperatures to produce steam from the waste heat, which is used to generate electricity for sale. Some plants can also supply hot water to provide district heating for local buildings. Typical plants in the UK have capacities between 55,000 tonnes to 400,000 tonnes of waste per year. The majority have been built in partnership with the private sector with contract commitments for a 20 to 30 year period. A modern incinerator facility can reduce the quantity of waste needing final disposal by up to 70%. Common concerns raised with respect to incinerators regard public health impacts and gaseous emissions. Of particular concern are dioxins and furans, because they are considered to be harmful to health. Dioxins and furans are produced as a by-product of combustion. Old incinerators of the 1960’s and 70’s, which were not very tightly regulated, operated at relatively low temperatures and with little or no air pollution control technology would have operated under conditions more conducive to dioxin and furan formation. Modern plants have tight operating conditions, with respect to temperatures and residence times, designed to minimise the generation of pollutants, including dioxins. In addition air pollution control systems are required to comply with strict emission standards laid down in EC directives. Anaerobic Digestion Anaerobic digestion is another form of treatment of biodegradable waste using bacteria. It takes place in an enclosed unit and is anaerobic because there is no oxygen present. This process produces methane gas as the waste decomposes. The enclosed unit allows emissions to be controlled and the methane gas to be collected. The gas can then be burnt to produce electricity. Odour can be a problem due to the anaerobic nature of the process. Anaerobic digestion has been used for some time in the UK for treating sewage sludge. Although there are no commercial plants treating solid waste in the UK, there are over 50 plants operating in Europe. These plants typically range in capacity from 10,000 to 50,000 tonnes of waste per year. The planning process may take 3 years. An anaerobic digestion plant with a capacity of approximately 50,000 tonnes of waste per year will take up an area of approximately 8,000m2 , the highest structure being the digester reactor vessel, in which the bacteria treats the waste, which may measure 25 m in height. Gasification and Pyrolysis Gasification and pyrolysis involve heating the waste in a low oxygen environment, as opposed to burning it, producing gas, liquid and solid fuels. These technologies are being used outside the UK, with the first UK demonstration sites currently being planned or developed. It is anticipated that a number of these demonstration facilities may be come operational in the near future Gasification heats waste in a low oxygen environment producing a gas. This can then be burnt in a gas turbine or gas engine to produce electrical power. In pyrolysis, waste is heated to a high Walsall MBC Waste Management Strategy – May 2004 temperature with no oxygen resulting in a gas or oil fuel which can be burnt to produce electricity and/or heat. Many of the proposed technologies require pre-treatment of the waste stream. The gasification / pyrolysis plants currently being proposed can treat up to 50,000 tonnes of waste annually depending on size. The planning process is similar to that required for incineration. A gasification/ pyrolysis plant with a capacity of approximately 150,000 tonnes of waste per year will probably require a site area of approximately 16,000m2, and may have a 8 m tall stack. Costs are currently difficult to estimate as it is not yet a commercial process, but are expected to be similar to those for incineration. Refuse Derived Fuel The production of Refuse Derived Fuel involves sorting waste to produce fuel pellets. The pellets can be burnt at a facility on the same site or in a different facility, to generate energy. This is an established technology in the UK where 5 plants are currently in operation, the closest to Walsall being in Berkshire. A Refuse Derived Fuel facility is similar to a MRF, in that it involves sorting municipal waste to remove the combustible material. The combustible material is either compressed and dried into fuel pellets if being transported, or sometimes shredded for immediate use. From municipal waste the process typically recovers 6% metal for recycling and 30-40% combustible material to be made into fuel pellets. The remainder is sent to landfill. The current facilities in the UK range in capacity from 50,000 to 100,000 tonnes of waste per year. A Refuse Derived Fuel plant with a capacity of approximately 100,000 tonnes of waste per year will take up an area of approximately 6,000m2 for the fuel production facility. An extra 1000 m2 is required for the combustion facility. The stack height will be similar to that for an incinerator. Overview of the energy from waste technologies Advantages of energy from waste Disadvantages of energy from waste Technology is proven in many European Countries Reduces volume of waste requiring landfill by up to 70%, depending on the technology Difficulties in identifying appropriate sites due to community concerns around dioxins and other pollutants May be located near to urban centres, reducing transport impacts Concerns over possible health effects of emissions, particularly dioxins Sophisticated facilities which ensure a high level of control over the process Disposal of ash and flue gas treatment residue is still required Replaces fossil fuel - a valuable resource which would otherwise be produced from non renewable sources like coal, oil and gas. Waste can be kept under a negative pressure to avoid the escape of dust and odour Visual impact due to industrial nature of buildings and possibly high stacks Capital intensive Local transportation impacts from the delivery of waste and collection of process residues. Walsall MBC Waste Management Strategy – May 2004 Landfill Landfill capacity will always be required regardless of the other waste management options used, to dispose of the waste remaining from other stages of the hierarchy. In the past, landfills were left unlined, and any pollutants were “managed” through ‘dilution and dispersion’. Nowadays, landfill sites are predominantly ‘contained’ - the site is lined and capped, and the gas and leachate produced are collected and treated. As landfill space is fast becoming filled, it has become increasingly difficult to find new landfill capacity. Current and forthcoming EU Directives will inhibit future landfill development. A typical landfill site may accept between 50,000-500,000 tonnes of waste per year. Legislation requires landfill pollutants including landfill gas and liquid/leachate emissions, to be controlled. Landfill gas (consisting of 50-60% methane and 35-40% carbon dioxide) may be captured and burnt to produce energy - see earlier notes. Regulation and Monitoring of Waste Management Facilities All waste management processes are closely regulated to ensure that environmental impacts to air, land and water are minimised. The Environment Agency is the national body responsible for monitoring and regulation of air, water and land. The Agency issues authorisations to operate the plant and regulate their operation, and is empowered to close down a plant not meeting regulations. The monitoring data is placed on public registers which are open for inspection. Walsall MBC Waste Management Strategy – May 2004
