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 municipal solid waste in Xing'an League, Inner Mongolia Autonomous Region are as follows: food waste 36.11%, paper 19.41%, rubber 14.35%, textile (fiber) 5.73%, wood and bamboo 3.87%, ash and soil 10.56%, bricks, tiles, and ceramics 2.11%, glass 2.89%, metals 2.64%, and others 2. 35%. Moisture content 46.41%, Higher Heating Value (HHV) 7088.35 kJ/kg, Lower Heating Value (LHV) 5320.43 kJ/kg. The carbon fraction of the initial waste, i.e., from biogenic sources is 60.4%. The proportion of unoxidized and largely recoverable metals in the waste (excluding very small or very thin components) is Iron: 60.03%; Aluminum: 17.81%; Copper: 72.83%. Total degradation rate of waste over 100 years: 18.73%. Degradability of the waste fraction: Paper: 27%; Mixed cardboard: 32%. 4% plastics: 1%; laminated materials: 18%; laminated packaging, such as beverage 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 9.39E-05 kWh of electricity and 3.38E-01 MJ of useful heat.
