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, or cardboard. The characteristics of municipal solid waste in Chongzuo City, Guangxi Zhuang Autonomous Region, are as follows: food waste 45.57%, paper 16.17%, rubber 19.9%, textile (fiber) 5.97%, wood and bamboo 5.19%, ash and soil 1.26%, brick, tile, and ceramics 0.61%, glass 2.88%, metal 1.82%, and others 0%. 64%. Moisture content 54.49%, higher heating value 7792.42 kJ/kg, lower heating value 5878.14 kJ/kg. The carbon fraction of the initial waste, i.e., from biogenic sources 60.4%. The proportion of unoxidized and largely recoverable metals in the waste (excluding very tiny or very thin components) Iron: 60.03%; Aluminum: 17.81%; Copper: 72.83%. Total degradation rate of waste over 100 years: 18.73%.
