Description
This dataset represents waste treatment activities of 'municipal solid waste' in sanitary landfills. It is recommended to use this dataset for average municipal/public waste mixtures. It is not suitable for representing any single specific waste, such as plastics, paper, or cardboard. The composition of municipal solid waste in Laiwu City, Shandong are as follows: kitchen waste 46.04%, paper 15.3%, rubber 19.62%, textiles (fibers) 4.81%, wood and bamboo 4.75%, ash and soil 5.31%, bricks, tiles, and ceramics 0%, glass 3.48%, metals 0.69%, others 0%. Moisture content 57. 98%, with a higher heating value of 7587.04 kJ/kg and a lower heating value of 5679.24 kJ/kg. The carbon fraction in the initial waste, i.e., of biogenic origin, is 60.4%. Proportions of unoxidized 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 goods, 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 1.85E-04 kWh of electricity and 6.68E-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.
