The methane (CH4) emission from MSW Landfill has effect on global warming. Using Maticorena Model,the generation of landfill methane in China was carried out. The methane potential of fresh waste,55.86 m3/t,was measured by an accelerated biodegradability test. According to the result,in 2020,the amount of methane generation from landfills in China will reach to 9.84 billion cubic meters. It provides the credible reference for the control and utilization of landfill gas.
