The dataset represents the waste treatment 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 plastic, paper, cardboard. The characteristics of municipal solid waste in Qiannan Buyi and Miao Autonomous Prefecture, Guizhou Province, are as follows: food waste 62.57%, paper 10.28%, rubber 9.84%, textiles (fibers) 0.51%, wood and bamboo 7.02%, ash and soil 0.68%, bricks, tiles, and ceramics 2.36%, glass 0.37%, metals 2.24%, and others 4.% 12%. Moisture content 66.28%, higher heating value 5643.45 kJ/kg, lower heating value 3721.97 kJ/kg. The initial share of carbon in the waste, that is, from biological sources, is 60.4%. The proportion of unoxidized and substantially 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 the waste over 100 years: 18.73%. The degradability of the components forming part of the waste: 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 generate 1.92E-04 kWh of electricity and 6.93E-01 MJ of useful heat.
