The dataset represents the waste management activity of \"municipal solid waste\" in a sanitary landfill. The recommended use of this dataset is for average municipal/public waste mixtures. It is not suitable to represent any single specific waste types, such as plastics, paper, or cardboard. The characteristics of municipal solid waste in Dali Bai Autonomous Prefecture, Yunnan Province, are as follows: kitchen waste 50.65%, paper 13.98%, rubber 17.04%, textiles (fibers) 5.16%, wood and bamboo 6.68%, ash and soil 0%, bricks, tiles, and ceramics 0.32%, glass 4.02%, metals 1.26%, and other types 0%. Moisture content 57. 03%, higher heating value 7089.1 kJ/kg, lower heating value 5179.22 kJ/kg. The carbon fraction from initial waste, i.e., 60.4% from biogenic sources. The proportion of unoxidized and largely recoverable metals in the waste (excluding very small or very thin components): Iron: 60.03%; Aluminum: 17.81%; Copper: 72.83%. 100-year general degradation rate of the waste: 18.73%. The degradability of the waste component: Paper: 27%; Mixed cardboard: 32%. 4% plastic: 1%; laminated materials: 18%; laminated packaging, such as beverage cartons: 18%; composite products, like 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 produces 2.26E-04 kWh of electricity and 8.13E-01 MJ of useful heat.
