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 plastics, paper, cardboard. The characteristics of municipal solid waste in Beihai City, Guangxi Zhuang Autonomous Region, are as follows: food waste 45.57%, paper 16.17%, rubber 19.9%, textiles (fibers) 5.97%, wood/bamboo 5.19%, ash and soil 1.26%, bricks, tiles, and ceramics 0.61%, glass 2.88%, metals 1.82%, and other 0%. 64%. Moisture content 54.49%, higher heating value 7792.42 kJ/kg, lower heating value 5878.14 kJ/kg. The carbon share from initial waste, that is, from biogenic sources, is 60.4%. The proportion of unoxidized and largely recoverable metals in the waste (excluding very small or very thin parts): Iron: 60.03%; Aluminum: 17.81%; Copper: 72.83%. Overall degradation rate of waste in 100 years: 18.73%.
