The dataset represents the waste management activity 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, cardboard. The characteristics of urban solid waste in Tianjin are as follows: food waste 56.9%, paper 15.3%, rubber 16.9%, textile (fiber) 3.9%, wood/bamboo 1.6%, ash/soil 0%, brick/tile/ceramic 2.9%, glass 1.6%, metal 0.7%, other 0%. Moisture content is 55%, and higher calorific value of 7021. 52 kJ/kg, lower heating value 5046.26 kJ/kg. The carbon fraction of initial waste, that is, from biogenic sources, is 60.4%. The percentage of unoxidized and recoverable metals in the waste (excluding very small or very 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 materials composing part of the waste: Paper: 27%; Mixed cardboard: 32%. 4% plastic: 1%; laminated materials: 18%; laminated packaging, such as carton drink boxes: 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%; the capture and utilization of landfill gas produce 1.86E-04 kWh electricity and 6.71E-01 MJ of useful heat.
