Description
This dataset represents the waste treatment activity of "municipal solid waste" in a sanitary landfill. Recommended use of this dataset: for an average municipal/public waste mixture. It is not suitable to represent any single specific waste such as plastics, paper or cardboard. The municipal solid waste characteristics of Hechi City, Guangxi Zhuang Autonomous Region are as follows: kitchen waste 27.51%, paper 14.15%, rubber 17.68%, textiles (fibre) 5.03%, wood and bamboo 6.03%, ash and soil 10.27%, bricks, tiles and ceramics 0%, glass 8.78%, metals 10.56%, others 0%. Moisture content 41.24%, higher heating value 6158.4 kJ/kg, lower heating value 4601.5 kJ/kg. The carbon fraction in the initial waste, i.e. of biogenic origin, is 60.4%. The proportion of unoxidised and bulk-recoverable metals in the waste (excluding very small or very thin components): iron: 60.03%; aluminium: 17.81%; copper: 72.83%. Overall degradation rate of the waste over 100 years: 18.73%. Degradability of the constituent waste fractions: paper: 27%; mixed cardboard: 32.4%; plastics: 1%; laminated materials: 18%; laminated packaging, e.g. beverage cartons: 18%; composite goods, e.g. 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 utilisation produces 1.73E-04 kWh of electricity and 6.23E-01 MJ of useful heat.
Process Description
“Municipal solid waste” is primarily generated from a wide range of activities in many different sectors. "Municipal solid waste" includes the following components: food waste, paper, rubber, textile (fiber), wood and bamboo, dust, bricks, ceramics, glass, metal and potentially other components.
Such by-products (recyclables or waste) are generated by common transformation activities and can therefore be considered for modeling waste outputs of similar composition.
In the HiQ database, disposal methods for this by-product include: sanitary landfill, municipal incineration. In addition, this by-product is used in the following processes: Clinker production.

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