Description
This dataset represents the treatment mix (technology mix) for 'municipal solid waste, municipal incineration'. It is recommended for use with average municipal/public waste mixtures and is not suitable for representing any single specific waste type, such as plastics, paper, or cardboard. The composition of municipal solid waste in Jiangxi are as follows: kitchen waste 52.5%, paper 5.5%, rubber 6%, textiles (fibers) 3%, wood and bamboo 3%, ash and soil 0%, bricks, tiles and ceramics 20.5%, glass 5.5%, metals 3%, others 1.36%. Moisture content is 55.81%, and the higher heating value is 4526. 97 kJ/kg, lower heating value 2820.89 kJ/kg.
Municipal waste incineration produces 0.205 kg of slag per kg of this waste and 0. 0.5 kg of fly ash and bottom ash are landfilled after precious metal recovery; the fly ash is solidified with cement at a ratio of 1:1. The thermal efficiency of waste heat electricity generation is taken as the average value of 22%; in the waste heat heating process, no different forms of heat-to-energy conversion are involved, so the thermal efficiency is relatively high, taken as the average value of 64%. By considering both the heat recovery for electricity generation and direct heating, 15% of the heat generated from waste incineration is used for electricity generation, and 56% for direct heating.
The proportions of waste incineration scenarios are 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.
