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 Guian New Area, Guizhou are as follows: kitchen waste 62.57%, paper 10.28%, rubber 9.84%, textiles (fibers) 0.51%, wood and bamboo 7.02%, soil and ash 0.68%, bricks, tiles, and ceramics 2.36%, glass 0.37%, metals 2.24%, others 4.12%. Moisture content: 66. 28%, higher heating value 5643.45 kJ/kg, lower heating value 3721.97 kJ/kg. The carbon fraction from biogenic sources in the initial waste is 60.4%. Proportion 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. Plastics: 1%; laminated materials: 18%; laminated packaging, such as beverage cartons: 18%; composite products, such as disposable 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 capture and utilization generate 1.92E-04 kWh of electricity and 6.93E-01 MJ of useful heat.
Process Description
Heat is generated during waste landfilling activities and is typically reused within the activity itself.

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.
