Economic and GHG emission policy co-benefits for IWM planning across the GCC
Paper Proposal Text :
This ambitious assessment provides a detailed analysis of regional Gulf Cooperation Council (GCC) country municipal solid waste (MSW) arisings data and information collected for the UNEP Geo6 West Asia Assessment using a new waste economic emission model (WEEM) currently under development to assess a range of waste infrastructure treatment and disposal options taking into account waste, transport, process and supply chain emissions and costs.
The estimated MSW arisings collected in GCC countries in 2015 is 25.8 million tonnes and this is expected to grow to 47.5 million tonnes by 2030. The release of emissions to air from MSW has increased from about 21,920 GgCO2eq in 2000 to an estimated 38,247 GgCO2eq based on MSW arisings in 2015, and most of the MSW being deposited in unlined landfill sites or dumpsites. To address the significant adverse socio economic and environmental issues caused by poor regional waste management practices. The paper will develop the political context (workshop theme T1) required to ensure the development, implementation and ongoing long term operation of Integrated Waste Management (IWM) measures (Physical/Environmental – theme T2) assessed using the WEEM model that provides a link to the socio cultural theme T3 and the supply chain interventions that are needed to support future growth through sustainable consumption and production.
The study utilises available data, modelling this to present for the first time, a detailed picture of GCC MSW arisings, characterisation, composition, (IWM) technology processes and transport. The WEEM details waste characterisation, composition, emission and economic factors to assist in the choice, development and implementation of suitable IWM and circular economy systems in the GCC provides decision makers with comparative key economic and emission data that will inform policy, planning and control interventions.
The study will develop emission and cost of emission avoidance profiles for the 3 main treatment and disposal interventions based on a range of segregated composting and recycling collection options, with the residual wastes going to facilities that bury in the waste in dumpsites or lined landfills with gas recovery, recovering and recycle as much solid waste as possible, or burn the waste for energy. The emission savings from supply chain use and further recycling cycles are assessed. The selection of the right technology and waste collection intervention is important as it has impacts on waste producers who dependant on option chosen will need to change how they sustainably procure, use goods and manage their resultant waste arisings. This requires further support in the supply chain through Extended Producer Responsibility (EPR) initiatives utilising the waste hierarchy by detoxifying, decreasing materials used, increasing opportunities to reuse and improving segregation of waste types. Such a synergic process will start to decrease and decouple MSW waste arisings from economic growth factors and see the emergence of a true circular economy.
The study relates the economic aspects of emission avoidance from the application of each technology and transport option, setting out the costs for options that will achieve zero MSW emissions or greater. This will enable decision makers to select a range of appropriate solutions independently. Currently choices made by decision makers in the selection of waste treatment and disposal technologies are largely based on waste management providers commercial or consultant advisor expertise.
The estimated annual cost for the investment in the development of necessary IWM infrastructure and facilities to reduce regional GCC GHG MSW sector emissions by up to 117% is about 0.34% of gross domestic product (GDP). Further private sector investment would of about 0.23% of annual GDP would be required to develop value added remanufacturing industries utilising recycled waste as a raw materials. Development and implementation of IWM and remanufacturing infrastructure capacity would address key GCC policy drivers and pressures by;
• Significantly reducing dependence on dumpsites and unlined landfill disposal,
• Reducing net MSW sector greenhouse gas (GHG) emissions towards or below zero,
• Return a significant quantity of recycled waste into the supply chain, decreasing virgin raw material demand, and
• Creating conditions for significant economic growth.
This is important information for GCC decision makers in relation to the progression of regional Sustainable Development Goals (SDG) supporting sustainable consumption and production and the implementation of control measures affecting waste generation, waste arisings and extended producer responsibility in the supply chain.
