The dataset represents the waste treatment activities of \"municipal solid waste\" in a sanitary landfill. The recommended use of this dataset is for the average municipal/public waste mixture. It is not suitable to represent any single specific waste type, such as plastics, paper, or cardboard. The characteristics of municipal solid waste in Haibei Tibetan Autonomous Prefecture, Qinghai Province, are as follows: kitchen waste 47.78%, paper 6.85%, rubber 9.41%, textile (fiber) 2.72%, wood and bamboo 1.75%, ash and soil 0%, brick, tile, and ceramics 27.22%, glass 2.89%, metal 1.21%, and other 0.17%. Moisture content 55%. 81%, higher heating value 5367.35 kJ/kg, lower heating value 3624.71 kJ/kg. The carbon share from the initial waste, i.e., 60.4% biogenic. The proportion of non-oxidized and recoverable metals in the waste (excluding very small or very thin components): Iron: 60.03%; Aluminum: 17.81%; Copper: 72.83%. Overall degradation rate of waste in 100 years: 18.73%. Degradability of the waste components: Paper: 27%; Mixed cardboard: 32%. 4% plastic: 1%; laminated material: 18%; laminated packaging, such as drink cartons: 18%; composite goods, such as diapers: 18%; glass: 0%; textiles: 12%; minerals: 0%; natural products: 27%; compostable materials: 27%; inert metals: 10%; volatile metals: 0%; batteries: 0%; electronics: 0%; landfill gas capture and utilization generates 6.86E-05 kWh of electricity and 2.47E-01 MJ of useful heat.
