Abstract: The construction and operation of Asuwei Waste Sanitary Landfill were briefed,the refuse components and refuse quantities analyzed,and the component of the landfill gas measured.Based on an EPA gas produce projection model,the gas output from Asuwei landfill will be about 33.7×(10~6 m~3/a) from 2005 to 2039. Different landfill gas recovery technologies were also compared and it is found that power generation by landfill gas is the best recovery utility contrary to other technologies.The technical and economical feasibility analysis shows that the total investment of landfill gas power generation project is 33.94 million yuan,and the annual direct economic benefit is 2.30 million yuan.
