The dataset represents the waste management activity of \"municipal solid waste\" in a sanitary landfill. The recommended use of this dataset is for the average municipal/public waste mixture. It is not suitable to represent any single specific waste, such as plastic, paper, or cardboard. The characteristics of municipal solid waste in Wulanchabu City, Inner Mongolia Autonomous Region, are as follows: kitchen waste 36.11%, paper 19.41%, rubber 14.35%, textile (fiber) 5.73%, wood and bamboo 3.87%, ash and soil 10.56%, bricks and tiles ceramics 2.11%, glass 2.89%, metal 2.64%, and other 2%. 35% moisture content, higher calorific value 7088.35 kJ/kg, lower calorific value 5320.43 kJ/kg. The carbon fraction of the initial waste, i.e., biogenic share is 60.4%. The non-oxidized and largely recoverable metal proportion in the waste (excluding very small or very thin parts): Iron: 60.03%; Aluminum: 17.81%; Copper: 72.83%. Overall degradation rate of waste over 100 years: 18.73%.
