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, or cardboard. The characteristics of municipal solid waste in the Altay region of the Xinjiang Uygur Autonomous Region are as follows: food waste 76%, paper 2.4%, rubber 5.4%, textile (fibers) 4.2%, wood/bamboo 2.5%, ash and soil 0%, bricks, tiles, and ceramics 6.4%, glass 2.4%, metal 0.8%, and other 0%. Moisture content is 47%, and higher calorific value of 4148. 64 kJ/kg, lower heating value 2183.4 kJ/kg. The carbon fraction of initial waste, i.e., 60.4% biogenic. The proportion of unoxidized and substantially recoverable metals in the waste (excluding very small or very thin parts) Iron: 60.03%; Aluminum: 17.81%; Copper: 72.83%. Total degradation rate of waste over 100 years: 18.73%. Degradability of the waste fraction composition: Paper: 27%; Mixed cardboard: 32% 4% plastic: 1%; laminated materials: 18%; laminated packaging, such as drink 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 produce 8.68E-05 kWh of electricity and 3.12E-01 MJ of useful heat.
