Characteristics of greenhouse gas emissions from municipal solid waste treatment in Guangzhou and recommendations for emission reduction
According to the mass balance method of the"IPCC Guidelines for National Greenhouse Gas Inventories",this study measured the emissions of major greenhouse gases such as CO2 and CH4 produced by different treatment methods of domestic waste in Guangzhou from 2011 to 2022,and analyzed the variation characteristics of CO2 emissions equivalent with time.From 2011 to 2022,the trend of CO2 emissions equivalent from domestic waste disposal in Guangzhou increased first and then decreased,with the peak in 2017 and the minimum value in 2022.This trend was mainly attributed to the change of treatment methods of domestic waste from landfill-based to incineration-based,while CO2 emissions equivalent of incineration-based treatment than landfill-based,thus CO2 emissions equivalent greatly reducing.This study proposes to strengthen policy guidance,establishes a system of carbon accounting data and quality management,continues to promote waste classification,optimize incineration technology,explore the co-combustion of stock waste,and promote carbon emission reduction in the industry.
