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 mix. It is not suitable to represent any single specific waste, such as plastics, paper, cardboard. The characteristics of municipal solid waste in Ledong Li Autonomous County, Hainan Province, are as follows: kitchen waste 58.42%, paper 6.44%, rubber 11.93%, textile (fiber) 0.89%, wood and bamboo 1.6%, ash and soil 0%, brick, tile and ceramics 12.92%, glass 0.53%, metal 0.68%, and others 6.47%. The moisture content is 55%. 81%, Higher Heating Value (HHV) 5556.5 kJ/kg, Lower Heating Value (LHV) 3706.33 kJ/kg. The carbon share from initial waste, i.e., 60.4% biogenic. The unoxidized and largely recoverable metal content in the waste (excluding very small or very thin components): Iron: 60.03%; Aluminum: 17.81%; Copper: 72.83%. Overall degradation rate of waste over 100 years: 18.73%.
