The dataset represents the waste management 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 Qiannan Buyi and Miao Autonomous Prefecture, Guizhou Province are as follows: food waste 62.57%, paper 10.28%, rubber 9.84%, textile (fiber) 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 carbon fraction of the initial waste, which is of biological origin, 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%. The overall degradation rate of waste over 100 years: 18.73%.
