Description
This dataset represents the waste treatment activity of 'municipal solid waste' in a sanitary landfill. 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 Ulanqab City, Inner Mongolia Autonomous Region are as follows: kitchen waste 36.11%, paper 19.41%, rubber 14.35%, textiles (fibers) 5.73%, wood and bamboo 3.87%, ash and soil 10.56%, bricks, tiles, and ceramics 2.11%, glass 2.89%, metals 2.64%, others 2. 35%. Moisture content 46.41%, gross calorific value 7088.35 kJ/kg, net calorific value 5320.43 kJ/kg. Carbon fraction in the initial waste, i.e., biogenic: 60.4%. Proportions of non-oxidized and largely recyclable metals in 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. 4%; Plastic: 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 recovery and utilization generates 9.39E-05 kWh of electricity and 3.38E-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.
