Description
This dataset represents the waste treatment activity of 'municipal solid waste' in sanitary landfills. It is recommended for use with average municipal/public waste mixtures. It is not suitable for representing any single specific waste type, such as plastics, paper, or cardboard. The composition of municipal solid waste in Zhangjiajie City, Hunan, are as follows: kitchen waste 25.71%, paper 18.27%, rubber 22.26%, textiles (fibers) 11.24%, wood and bamboo 2.33%, ash and soil 11.16%, bricks, tiles, and ceramics 1.77%, glass 2.37%, metals 2.03%, and others 2. 86%. Moisture content 52.39%, higher heating value 8525.15 kJ/kg, lower heating value 6747.63 kJ/kg. Carbon fraction in the initial waste, i.e., biogenic: 60.4%. Proportions of non-oxidized and largely recyclable metals 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%. Degradability of waste components: paper: 27%; mixed cardboard: 32. Plastic: 1%; Laminated materials: 18%; Laminated packaging, e.g., beverage cartons: 18%; Composite goods, such as diapers: 18%; Glass: 0%; Textiles: 12%; Minerals: 0%; Natural products: 27%; Compostable materials: 27%; Inert metals: 10%; Volatile metals: 0%; Batteries: 0%; Electronics: 0%; Landfill gas recovery and utilization produces 2.03E-04 kWh of electricity and 7.33E-01 MJ of useful heat.

Technology comment
This is an inventory for a sanitary (controlled) landfill site for municipal solid waste. The final average landfill height is 20 meters. The operational phase lasts for 30 years. Landfill gas collection and utilization begin one year after waste disposal and continue for 30 years. The landfill gas utilization efficiency is 70%, with 50% converted into electricity and 50% into heat. Leachate collected during the first 100 years is collected and treated prior to discharge.
