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 types, such as plastics, paper, cardboard.

Moisture content 64. 86%, higher heating value 5930.68 kJ/kg, lower heating value 4117.5 kJ/kg. The carbon share from the initial waste, that is, 60.4% biogenic. The proportion of non-oxidized and largely recoverable metals in the waste (excluding very small or very thin parts) Iron: 60.03%; Aluminum: 17.81%; Copper: 72.83%. Overall degradation rate of waste in 100 years: 18.73%.
