Description
This dataset represents the treatment mix (technology mix) for 'municipal solid waste, municipal incineration'. The recommended use of this dataset is for average municipal/public waste mixtures. It is not suitable to represent any single specific waste type, such as plastics, paper, or cardboard. The composition of municipal solid waste in Heilongjiang are as follows: kitchen waste 55.73%, paper 15.71%, rubber 17.98%, textiles (fibers) 5.29%, wood and bamboo 2.54%, ash and soil 0%, bricks, tiles, and ceramics 0%, glass 2.36%, metals 0.4%, others 0%. Moisture content 64. 6%, higher heating value 7409.11 kJ/kg, lower heating value 5419.33 kJ/kg.\n\nMunicipal waste incineration generates 0.205 kg of slag per kg of this waste and 0.05 kg of fly ash; after precious metal recovery from fly ash and slag, they are landfilled, and fly ash is solidified with cement at a ratio of 1:1. The average thermal efficiency for waste heat electricity generation is 22%; in the waste heat heating process, since no different forms of heat and energy conversion are involved, the thermal efficiency is higher, with an average value of 64%. By integrating the thermal efficiencies of both waste heat electricity generation and direct heating, 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 is estimated based on China's national conditions.
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.
