The dataset represents the waste management activity of \"municipal solid waste\" in sanitary landfills. 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 Ali region of the Tibet Autonomous Region are as follows: food waste 57%, paper 6%, rubber 12%, textiles (fiber) 7%, wood and bamboo 14%, ash and soil 0%, bricks, tiles, and ceramics 3%, glass 0%, metals 1%, and others 0%. Moisture content 47%, higher heating value 7185.47 kJ/kg, and lower heating value 5196 kJ/kg. 19 kJ/kg. The carbon fraction of the initial waste, i.e., 60.4% biogenic. 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%. Overall degradation rate of waste over 100 years: 18.73%. Degradability of waste components: 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 produces 1.16E-04 kWh of electricity and 4.17E-01 MJ of useful heat.
