Department for Environment, Food & Rural Affairs Research Study on International Recycling Experience Annex A A10 CANBERRA (AUSTRALIA) A10.1 OVERVIEW A summary description of Canberra and key recycling data is presented in Table A10.1. Table A10.1 Overview of Canberra City background Details Population 311 000 Density 460/km2 Type of area Urban Type of housing 78% detached, 13% semi-detached, 9% apartments Definition of MSW Non-hazardous waste from the domestic, commercial and industrial sectors; parks and garden waste. Recycling target To achieve a waste free society and have no MSW waste going to landfill by 2010 Recycling achievement Approximately 57% of total MSW is recycled (199899) Principal recycling drivers markets for recycled materials (in the 1980s); good collection facilities; public awareness and information activities. Canberra is not representative of New South Wales or, indeed, Australia in socio-economic terms. The population, characterised by civil servants, has higher than national average incomes and higher levels of education and environmental awareness than the rest of the country. There is also better coordination between decision makers due to the structure of local government. In other cities in Australia, there may be more than one government department working on this issue, making a coordinated approach to promotion of recycling activities less easy. The recycling rate in Canberra is, as a result, higher than most other states in Australia. A10.2 RECYCLING TRENDS The data shown in Figure A10.1 represents waste to landfill and waste recovery activity. There was no accurate record of landfill disposal prior to the introduction of weighbridges at landfills in 1993, but these levels are likely to have been at least as high as those recorded in 1993 to 1994. Only clinical waste is incinerated in Canberra. The involvement of the community in the process of policy setting and programme implementation have been key to the success of recycling in Canberra. Proposed services have been trialled and communities surveyed to develop services that best suit their requirements. Services have been introduced alongside comprehensive community education. Figure A10.1 MSW disposed to landfill and recycled Note: Data for MSW going to landfill was not available pre 1993. Figure A10.2 shows the percentages of the principal material types in MSW that originates from the household sector: Figure A10.2 Amounts of MSW recycled by type in the household sector and as a total (1998-9) Recycling from the household sector accounts for 35 per cent of recycling from MSW. Demolition waste, from the industrial and commercial sectors, accounts for nearly half of the remainder of MSW recycled in Canberra. Subtracting the figure for demolition waste recycling from the total figure for recycling of MSW, reduces the total recycling rate from 57 per cent to 29 per cent. The recycling rate for garden waste has seen the most dramatic rise, as shown in Figure A10.3. Figure A10.3 MSW recycling trends by material recovered Businesses and waste management operators are encouraged to provide details annually on recovery for the previous financial year. In many cases they use weighbridges so that the information supplied relates to actual tonnages. Firms accepting materials from local operators also provide details and these are matched with the former for consistency. For materials for which weighbridges are not used, (for example, composting operations) a conversion ratio for volume to weight is used, based on sample surveys and liaison with the operators. A10.3 MSW MANAGEMENT STRUCTURE Operation Australian Capital Territory (ACT) Waste is a business unit of the Department of Urban Services. ACT manages contracts and service agreements for a range of waste and recycling activities. Three year contracts are awarded to the private sector to deliver waste services. The three main components are outlined in Box A10.1. Box A10.1 Key Components of the Recycling Scheme Kerbside Collection. Provision of a 240 litre recycling bin to all residents, collected fortnightly by a contractor (paper and cardboard on one side and glass, plastics, drink cartons and cans on the other). For apartments, separate bins are provided for paper and containers. Recycling centres. Recycling centres and regional recycling centres (12 in total) where large quantities of paper and cardboard can be dropped off at the regional centres and large quantities of glass, metal and plastics can be dropped off at either centre. Recyclable materials are cleared every week and sent to recycling processors. Organic Waste recycling centres. Three sites for the public and businesses to drop off their prunings, grass clippings and leaves. The government engages contractors at these sites to compost these materials. In addition, commercial collections are made based on direct agreement between waste generators and collection contractors. The volume and frequency depend on the amount of waste, and nature of the material. For example, kitchen waste is likely to be collected more frequently than dry inert materials. A10.4 COLLECTION MECHANISMS AND ACCESSIBILITY All residential premises in Canberra are provided with a separate collection service. Table A10.2 provides a detailed summary of the programmes. A10.4.1 Participation Rate Participation is estimated to be 97 per cent for the kerbside collection scheme. The remaining three per cent is thought to include vacant dwellings. Type of Recyclable Material Method & Coverage Domestic: paper and card, and containers (glass, plastic, metal, cartons) For houses: kerbside collection introduced in November/ December 1994.For apartments (6 units): 240 litre bins are provided with paper and cardboard, and other recyclable material. These are collected fortnightly. The number of bins and service frequency can be varied depending on the generation of material and available space in each specific location. Where the number of units exceeds 30 units, then 1.1 cubic metre hoppers are used with one for paper and the other for containers Paper and card, containers; motor oils; metals, bulky goods Four regional recycling centres, with similar facilities at both landfills. Recycling containers also provided at a further six shopping centres. Parks and gardens Three recycling centres. On-site shredding using mobile equipment. Commercial - paper Recycling containers. Limited kitchen waste and card collection. Regional recycling centres sites. Construction waste Direct delivery to one reprocessing centre. A10.5 COSTS AND REVENUES Table A10.3 outlines the capital costs of the kerbside collection scheme. Operational costs are commercially confidential and therefore not available. Total costs of the domestic refuse and recycling services, including operational, capital and administration costs, are estimated to be AUS$75 (£30) per household per annum. This includes a cost of around AUS$33 per annum per household to finance the kerbside collection programme. Approximately AUS$60,000 (£23,640)[1] is spent annually on promoting the kerbside collection. Table A10.3 Capital Costs for Kerbside Recycling Number Capital Approximate Cost (£) Total Cost (£) 100,000 240 litre divided bins 20 each 2 million 100,000 140 litre waste bins 16 each 1.6 million 11 Recycling trucks 98,500 each 1.083 million 1 Materials Recycling Facility 591,000 591,000 AUS$1 = £0.394 (www.xe.net/ucc/) The revenue from waste charges does not fully cover the costs of the recycling activities. Payments made from the municipality to contractors includes a subsidy for the production of recyclate. Market prices do not cover the production costs of recyclate. Land is also provided for contractors on which to operate, at nominal rents. The recovery programme has created 140 new jobs in Canberra in the last six years. A10.6 CRITICAL SUCCESS FACTORS Good market prices for recyclables in the 1980s encouraged private industry to become involved in recycling and voluntary approaches were encouraged. Prices dropped through the 1990s. Strong markets were replaced by public awareness and demand for waste management options other than disposal as principal drivers of recycling. The municipality has matched this demand with good separate collection facilities that include kerbside collection. A10.7 LEGAL/REGULATORY REQUIREMENTS There are no statutory requirements to encourage recycling at present. Table A10.4 outlines pending legal requirements. Table A10.4 National, County and Municipal Legislation Geographical Legislation Area Details /Purpose National National Used Based on the principle of ‘product Packaging stewardship’, all supply chain Covenant participants accept responsibility for the environmental impacts associated with their sphere of activity. New South Wales Waste Minimisation and Management Act 60% reduction in waste to landfill by 2010. Sets up regional ’waste boards’ to formulate and implement waste minimisation policy.Introduce levy on waste sent to landfill.Increase environmental controls on landfills. Canberra Used Packaging Materials Environment ACT is currently developing legislation to enact the Used Packaging Materials National Environment Protection Measure (NEPM) in the ACT. It is proposed that this legislation is broad enough to allow for regulation of other waste materials where it is deemed necessary because voluntary approaches are not achieving the desired outcome. A10.8 FISCAL INCENTIVES A10.8.1 Waste Disposal Costs There is no incineration of MSW. Landfill charges for MSW are AUS $25 (£10). They are relatively low, suggesting that, in the absence of regulatory drivers, public awareness is a key driver for the high recycling rates. Waste delivered by the public is charged per vehicle load: 1993 - no charges; 1996 - £1.20 car, £2 trailer/utility; 1999 - same as 1996. Commercial waste is charged by weight: 1993 charges introduced: approximately £4.33 per tonne; 1996 - £8.66 per tonne; 1999 - £10 per tonne. A10.8.2 Charging Systems for Waste Management Residents pay for provision of services through local authority tax rates. A10.9 PUBLIC AWARENESS Public awareness is considered to be exceptionally high in Canberra, reflected in community attitude surveys and the high rates of participation in the kerbside collection programme. Promotion of recycling uses a wide range of media such as brochures, booklets, annual progress reports, waste calendars, internet websites and radio advertising. A10.10 MARKETS FOR END PRODUCTS Markets exist for most materials (see Table A10.5). The government is a major purchaser of recycled paper, compost and aggregates. In addition, construction firms and civil contractors purchase significant amounts of aggregates and compost. Recycled products are usually cheaper, and, in some cases, outperform virgin products (for example, recycled concrete as sub-base). The use of recyclate may be used as an opportunity for the business to promote an image of environmental responsibility. Other products have a broad range of buyers, including retailers and consumers. Table A10.5 Examples of Recyclate Use Material Newsprint and magazines Use De-inked and recycled as newsprint. Cardboard and mixed paper Turned into cardboard. Glass containers Recycled into containers of the same colour. Aluminium cans and foil Smelted back into aluminium. Steel cans Tin coating removed and then smelted as steel. Plastics Recycled into other plastic products (usually non- food applications). Bulky waste Crushed and separated for smelting back into ferrous products. Garden waste Composted to produce a range of mulch/compost and soil-conditioning products. Construction waste. Crushed and graded to form aggregate products for use in construction and civil works. Problems in Markets for Recovered Materials Major issues associated with the marketing of recyclate are: the limited market outlets; price variability determined by supply and demand fluctuations. If there is oversupply, acceptance specifications tend to be tightened; and the removal of barriers that limit the use of recycled products, for example, modification of technical specifications or regulations that require ‘new’ materials to be used, such as in road construction and use of building materials. A10.11 FUTURE DEVELOPMENTS Future developments in Canberra include: trials of bio-bins to collect organic waste including kitchen waste from households; trials of organic collections from commercial waste generators, particularly restaurants and supermarkets; development of Resource Recovery Estates[2] and infrastructure to facilitate recovery levels; removal of barriers to uptake of recyclables by: i. developing recognised specifications for recycled products that demonstrate performance characteristics; ii. facilitating demonstration projects using recycled products; iii. establishing government purchasing policies requiring recycled products to be given preference; iv. promoting and encouraging private business to adopt similar purchasing policies, for example, there is a Buy Recycled Business Alliance operating in Australia; development of alternative markets by encouraging a broader range of uses to supplement the recognised primary markets for each material. This builds on the Clean Washington Centre concept and an Australian Market Development Network which has been established to progress this further. It also involves targeting of materials where the primary markets are unable or unwilling to take all of the recovered material, for example, glass fines.[3] Alternative markets in this case may be in producing materials suitable for sand blasting, glass tile manufacture and swimming pool filters, and establishment of further waste legislation. [1] AUS$ 1 = £ 0.394 (www.xe.net/ucc/) [2] Resource Recovery Estates are dedicated recycling sites which seek to relocate waste material processing plants, to encourage efficiency and economies of scale, and cottage industries to encourage innovation in the field of returning wastes to resources. Education centres are also planned to strengthen public awareness. [3] Glass fines are small pieces of glass (up to 2 cm) that are not currently accepted by glass recyclers.
