Description
This dataset represents the treatment mix (technology mix) for 'municipal solid waste, municipal incineration'. The recommended use of this dataset is for an average municipal/public waste mixture. It is not suitable for representing any single specific waste type, such as plastics, paper, or cardboard. The composition of municipal solid waste in Anhui is as follows: kitchen waste 43.66%, paper 17.77%, rubber 20.55%, textiles (fibers) 4.66%, wood and bamboo 2.84%, ashes and soil 2.4%, bricks, tiles and ceramics 1.07%, glass 1.66%, metals 2.09%, others 3.3%. Moisture content: 58. 03%, higher heating value 7781.59 kJ/kg, lower heating value 5894.38 kJ/kg.\n\nMunicipal solid waste incineration generates 0.205 kg of bottom ash and 0 per kg of this waste. 0.05 kg of fly ash is landfilled after precious metal recovery from boiler slag, and the fly ash is stabilized at a 1:1 ratio with cement. The average thermal efficiency for waste heat electricity generation is assumed to be 22%; in the waste heat heating process, no different forms of heat and energy conversion are involved, thus the thermal efficiency is relatively high, taken as an average of 64%. By integrating the thermal efficiencies of the waste heat electricity generation and direct heat supply processes, 15% of the heat generated from waste incineration is used for electricity generation, and 56% is used for direct heating.
The proportion of waste incineration conditions is estimated based on China's national circumstances.
Process Description
"Municipal solid waste" is primarily generated from a wide range of activities across many different sectors. "Municipal solid waste" includes the following components: kitchen waste, paper, rubber, textiles (fibers), wood and bamboo, ashes and soil, bricks, tiles and ceramics, glass, metals, and potentially other fractions. This by-product (recyclable or waste) arises from common transformation activities and can therefore be considered for modeling waste outputs of similar composition. In the HiQ database, treatment methods for this by-product include: landfilling – sanitary landfill, municipal incineration. Additionally, this by-product is used in the following process: clinker production.
