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 mix. It is not suitable to represent any single specific waste such as plastics, paper or cardboard. The characteristics of municipal solid waste in Hengyang, Hunan Province are as follows: food/kitchen waste 37.19%, paper 22.9%, rubber 22.84%, textiles (fibres) 9.93%, wood and bamboo 3.41%, ash and soil 0%, bricks/tiles and ceramics 1.15%, glass 2.14%, metals 0.45%, others 0%. Moisture 51.43%, higher heating value 9094.91kJ/kg, lower heating value 7146.88kJ/kg. The share of carbon in the initial waste that is of biogenic origin is 60.4%. The proportion of metals in the waste that is unoxidised and largely recoverable (excluding very small or very thin components): iron: 60.03%; aluminium: 17.81%; copper: 72.83%. Overall waste degradation rate over 100 years: 18.73%. Degradability of the constituent waste fractions: paper: 27%; mixed cardboard: 32.4%; 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 utilisation generates 2.54E-04 kWh of electricity and 9.14E-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.
