Abstract: In order to explore the resource utilization of stale refuse in formal landfill, in this study, a municipal solid waste landfill in Beijing was taken as the research object. According to the size, mixed samples were divided into several groups and sorted manually, and their physical and chemical properties were analyzed. The results showed that stale refuse from the group of 0~60 mm were mainly humus soil and accounting for 53.08% of total stale refuse, and grain size of the combustible refuse such as plastic were mainly concentrated in 60 mm above, accounting for 30.46% of total stale refuse. Therefore, the stale waste of the landfill could be screened by 60 mm mesh to realize the coarse classification of humus soil and combustible refuse. Referring to the control standards for urban wastes for agricultural use (GB 8172-1987), the overall total nitrogen content was low in humus soil, and ascaris egg mortality exceeded the standard at some individual points, and other items in humus soil were qualified, which could realize reuse through composting, nitrogen sources supplement and cement kiln alternative raw materials. After screening, the average calorific value of combustible refuse reached 23.13 MJ/kg, and the moisture content and ash content were 15.32% and 10.21% respectively. According to the code for design of industrial waste co-composition in cement kiln (GB 50634-2010). Combustible refuse can be reused as a cement kiln alternative fuels.
