Abstract:Based on the calculation of carbon emission from municipal solid waste (MSW) treatment processes by using the mass balance model, a low-carbon strategy for MSW management was established by evaluating the relatively low-carbon degree of these processes. Restaurant garbage digestion for methane production, MSW landfill for gas utilization, and incineration for power production had the lowest carbon emission, with low-carbon degrees of 93.7%, 75.3% and 71.0%, respectively. In areas where the above technologies were limited, semi-aerobic landfill and landfill with an aerobic stabilization pretreatment were also effective for carbon emission reduction, and their low-carbon degrees were 61.8% and 56.7%, respectively. According to the present MSW treatment status in China, it was estimated that the CH4 emission was above 6 million tons and the total carbon emission was about 150 million tons per year from MSW treatment. With the implementation of the low-carbon management strategy, in 2015, the CH4 emission and the total carbon emission could be reduced to approximately 5 million tons and 130 million tons, respectively.
