The municipal solid waste management (MSWM) is one major concern in Cambodia due to complicated problems from waste sector. Until now, because of poor MSWM, solid wastes have produced high pollution, like methane (CH4), nitrous oxide (N2O), and carbon dioxide (CO2), which are the substances of greenhouse gas affect to climate change. Therefore, this study was undertaken to estimate and compare the greenhouse gas (GHG) emission from municipal solid waste in different cities namely; Phnom Penh, Battambang, and Siem Reap of Cambodia. GHG emission was calculated through Intergovernmental Panel on Climate Change (IPCC) calculator 2006 based on secondary data of 2009 for all cities. In order to reduce the GHG emission, four scenarios were proposed with different waste treatment technologies such as composting, anaerobic digestion, waste reduction at landfill by separating waste for recycling before disposal off in landfill, and landfill with gas recovery as well. Additionally, the multiple benefits of implementing the proposed scenarios may include reduction of GHG emission, promotion of energy saving for landfill operation, and promotion of the renewable energy concept like electricity.

Avoided Emissions

More light is being shed continually on the environmental impacts of municipal solid waste due to the increasing amounts of waste generated and the related greenhouse gas emissions. Emissions from MSW account for 20% of Canadian greenhouse gas (GHG) emissions and accordingly, waste legislation in Ontario demands high waste recovery and a moving towards a circular economy. This study evaluates the current municipal solid waste management in the City of Guelph and assesses possible alternative scenarios based on the associated GHG emissions. Waste Reduction Model (WARM) that was developed by the US-EPA has been used to quantify the GHG emissions produced over the entire life cycle of the MSW management scenario. Sensitivity analysis was also conducted to investigate the influence of some scenarios on the overall GHG emissions. It has been found that one ton of landfilled waste generates approximately 0.39 ton of carbon dioxide equivalent (CO2Eq). It was also found that the current solid waste scenario has a saving of 36086 million ton of CO2Eq (MCO2Eq). However, the results showed that the scenario with enhanced waste-to-energy, reduction at source and recycling has resulted in a high avoided emissions (0.74 kg CO2Eq/kg MSW). The anaerobic Digestion scenario caused the lowest avoided emissions of 0.39 kg CO2Eq/kg MSW. The net avoided emissions for reduction at source scenario were found to be the same as that found by the current scenario (0.4 kg CO2Eq/kg MSW). The sensitivity analysis of both reduction at source and recycling rates show a linear inverse proportional relationship with total GHG emissions reduction.
