National Waste Reporting 2013 FACTSHEET – JURISDICTIONAL WASTE PROFILES WESTERN AUSTRALIA (WA) Policy framework Legislation Waste Management in Western Australia is governed predominantly by the Waste Avoidance and Resource Recovery Act 2007 (WARR Act). The WARR Act establishes the Waste Authority as the primary advisory board to the Government on waste management. The Waste Avoidance and Resource Recovery Levy Act 2007 (WARR Levy Act) and Waste Avoidance and Resource Recovery Levy Regulations 2008 implement a landfill levy. Waste facilities, such as landfills and waste processing plants, are required to hold a licence under the Environmental Protection Act 1986. Policies/strategies The Waste Strategy “Creating the Right Environment” was released in March 2012. It is the basis for policies and programs implemented by the Waste Authority. It sets waste diversion targets for municipal solid waste, commercial and industrial waste and construction and demolition waste. It outlines five key strategic objectives. These are: 1. Initiate and maintain long-term planning for waste and recycling processing, and enable access to suitably located land with buffers sufficient to cater for WA’s waste management needs. 2. Enhance regulatory services to ensure consistent performance is achieved at landfills, transfer stations and processing facilities. 3. Develop best practice guidelines, measures and reporting frameworks and promote their adoption. 4. Use existing economic instruments to support the financial viability of actions that divert waste from landfill and recover it as a resource. 5. Communicate messages for behaviour change and promote its adoption, and acknowledge the success of individuals and organisations that act in accord with the aims and principles in the Strategy and assist in its implementation. Waste diversion targets The waste diversion targets given in the Waste Strategy are as follows: Municipal Solid Waste Sector Targets: - 50 per cent diversion from landfill of material presented for collection in the metropolitan region by 30 June 2015 - 65 per cent diversion from landfill of material presented for collection in the metropolitan region by 30 June 2020 - 30 per cent diversion from landfill of material presented for collection in major regional centres by 30 June 2015 - 50 per cent diversion from landfill of material presented for collection in major regional centres by 30 June 2015. 1 Construction and Demolition Waste sector targets: - 60 per cent diversion from landfill of material presented for collection across the State by 30 June 2015 - 75 per cent diversion from landfill of material presented for collection across the State by 30 June 2020. Commercial and Industrial Waste Sector Targets: - 55 per cent diversion from landfill of material presented for collection in across the State by 30 June 2015 - 70 per cent diversion from landfill of material presented for collection across the State by 30 June 2015. Levies A landfill levy applies to all waste disposed to landfill in the metropolitan area and to all waste generated in the metropolitan area regardless of where it is disposed. The landfill levy is currently $28 per tonne for putrescible landfills (Category 64, 65 under the Environmental Protection Regulations 1987) and $12 per cubic metre for “inert” landfills (Category 63 under the Environmental Protection Regulations 1987). Putrescible landfills only pay the landfill levy on 92 per cent of the waste received. Both putrescibles and inert landfills may apply for exemptions from the levy under certain circumstances, for example for material that is received on site but collected for recycling, not disposed to landfill. Classification trees Figure 1: WA waste classification system 2 Infrastructure The Western Australian Government has identified that the current network of landfills, alternative waste treatment facilities and recycling facilities are not adequate to meet the targets set out in the Waste Strategy. The Waste Authority is currently preparing a Waste and Recycling Infrastructure Plan for Perth and Peel that will propose the infrastructure required to meet the targets and the needs of the Perth/Peel region to a projected population of 3.5million. Details of the Strategic Waste Infrastructure Planning Program can be found at: http://www.wasteauthority.wa.gov.au/programs/funded-programs/strategic-wasteinfrastructure-planning/ 3 Waste and recycling data Per capita waste generation and resource recovery rate In 2010-11, Western Australians generated about 2.6 tonnes of waste per capita (see Figure 2), which was the equal highest rate (with ACT) of Australian jurisdictions. This unexpectedly high rate may partly result from the apparent assumption in WA waste data that the rate of waste generation in regional and rural areas is equal to that in Perth1. Per capita disposal in 2010-11 is estimated to have been 1.6 tonnes (79 per cent above the national average of 0.88 tonnes) and Australia’s third lowest resource recovery rate (39 per cent, which is 21 percentage points below the national average). The high landfill rate and low recovery rate are likely to be linked to the same data issue). Very large distances between collection points and recycling markets also constrain recycling in WA. Figure 2 Per capita waste generation by management by jurisdiction, 2010-11 Total waste generated Total waste generation in WA during 2010-11 is estimated at about 6.0 Mt excluding fly ash and 6.6 Mt including fly ash (see Figure 3). This is the fourth highest of Australia’s jurisdictions, consistent with WA’s ranking in relation to population and GSP. The estimate above is less than the waste generation estimate of 6.5 Mt reported in Recycling Activity in Western Australia 2010-11. The difference is mainly because the method for this report excludes soil, which was subtracted from the total based on the proportions identified by Waste Audit and Consultancy Services and Golder Associates (2007).in Disposal Based Audits of the C&I and the C&D Waste Streams. 1 The Waste Authority (2012) explains that the waste generation rate per capita for the whole state is assumed to be similar to that of metropolitan WA. Landfill tonnages outside Perth are estimated by subtracting known tonnages of recycling from the assumed tonnes generated. 4 Figure 3 WA total waste generation by management, 2010-11 Waste streams (Municipal Solid Waste (MSW), Commercial and Industrial (C&I) and Construction and Demolition (C&D)) Figure 4 WA total waste generation by waste stream and management, 2010-11 - MSW generation was around 1. 6 Mt with a resource recovery rate of 41 per cent, which is 10 percentage points below the Australian average. WA is targeting a MSW recovery rate of 50 per cent in metropolitan areas by 2015. - C&I waste generation was around 1.5 Mt with a resource recovery rate of 34 per cent, which is 25 percentage points below the Australian average. WA is targeting a C&I recovery rate of 55 per cent by 2015. - C&D waste generation was around 2.8 Mt with a resource recovery rate of 40 per cent, which is 26 percentage points below the Australian average. WA is targeting a C&D recovery rate of 60 per cent by 2015. These data may indicate relatively (compared to some jurisdictions) underdeveloped resource recovery infrastructure in WA. However, if the waste generation estimate is too high (see above), the true rates of resource recovery could be higher than those presented here. More information on the MSW, C&I and C&D waste streams is available in the overview on national waste stream profiles. 5 Material categories In WA, the waste categories that make up the bulk of waste generation are masonry, organics, metals, paper and cardboard, metals, fly ash and plastics (see Figure 5). Resource recovery rates for most material categories are below the national average. Figure 5 WA total waste generation by material category and management, 2010-11 Trends in waste generation and management 2006-07 to 2010-11 Figure 6 shows the per capita trends in waste generation and management for the period 2006-07 to 2010-11 in WA. Figure 6 WA trends in per capita waste generation and management, 2006-07 to 2010-11 Over the five-year period the following per capita trends are illustrated: - Waste generation in WA declined gently for most of the period but increased significantly in 2009/10. The increase is likely to be related to higher disposal rates due to a large rise in the landfill levy from $6 to $28 for MSW in 2009–10. Waste generators that had stockpiled waste requiring disposal may have offloaded the material before the introduction of the higher prices. The overall trend was a 1 per cent decrease over the five years. - The resource recovery rate increased from 31 per cent to 39 per cent between 2006/07 and 2010/11. - Recycling in WA increased significantly by 29 per cent. Analysis of the data suggests that the increase was mainly in recovery of waste concrete. - Waste tonnes allocated to energy recovery diminished by 28 per cent. - Waste disposal in WA decreased by 12 per cent. 6 Figure 7 shows the trends in total waste generation and management for the period 2006-07 to 2010/11 for WA. Figure 7 WA trends in total waste generation and management, 2006-07 to 2010-11 Over the five-year period the following trends are illustrated in relation to total waste tonnages: - waste generation increased by 10 per cent - recycling increased by 43 per cent - waste used for energy recovery decreased by 20 per cent - disposal declined by two per cent. Sourcing of data Information on policy frameworks and infrastructure were provided by the government department responsible for waste management and resource recovery in their state and territory. Unless otherwise specified, waste generation and resource recovery data for this factsheet were sourced from Blue Environment and Randell Environmental Consulting’s Waste Generation and Resource Recovery in Australia (2013). It is important to note that the data (from this report) will not always reconcile with publicly reported data from the states and territories. The differences in data result from differences in scope, method of compilation, and assumptions used in Waste generation and resource recovery in Australia. The workbooks provide transparency so that differences between the reported data sets can be reconciled if necessary. 7
