The dataset represents the waste treatment 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 Chuxiong Yi Autonomous Prefecture, Yunnan Province, are as follows: food waste 50.65%, paper 13.98%, rubber 17.04%, textiles (fibers) 5.16%, wood and bamboo 6.68%, ash and soil 0%, bricks and ceramics 0.32%, glass 4.02%, metal 1.26%, other 0%. Moisture content 57. 03%, higher heating value 7089.1 kJ/kg, lower heating value 5179.22 kJ/kg. The carbon fraction of the initial waste is 60.4% biogenic. The ratio of unoxidized and largely recoverable metal 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 waste for 100 years is: 18.73%.
