The dataset represents the waste management activities of \"municipal solid waste\" in a sanitary landfill. The recommended use of this dataset: for average municipal/public waste mixtures. It is not suitable to represent any single specific waste, such as plastics, paper, or cardboard. The characteristics of urban solid waste in Liangshan Yi Autonomous Prefecture, Sichuan Province, are as follows: food waste 50.09%, paper 15.54%, rubber 12.63%, textile (fiber) 2.34%, wood bamboo 7.78%, ash soil 0.32%, brick瓦陶瓷 1.42%, glass 0.09%, metal 0.8%, miscellaneous 0%. Moisture content 64. 86%, higher heating value 5930.68 kJ/kg, lower heating value 4117.5 kJ/kg. The carbon fraction of the initial waste, that is, the biogenic share is 60.4%. The proportion of non-oxidized and largely recoverable metals in the waste (excluding extremely small or extremely thin components) is: Iron: 60.03%; Aluminum: 17.81%; Copper: 72.83%. The overall degradation rate of waste over 100 years: 18.73%. The degradability of components that make up the waste portion: Paper: 27%; Mixed cardboard: 32. 4% plastic: 1%; laminated materials: 18%; laminated packaging, such as drink cartons: 18%; composite products, 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 generate 2.09E-04 kWh of electricity and 7.51E-01 MJ of useful heat.
