Description
This dataset represents the treatment mix (technology mix) for 'municipal solid waste, municipal incineration'. Recommended use of this dataset: for average municipal/public waste mixtures. It is not suitable for representing any single specific waste type, such as plastics, paper, or cardboard. The composition of municipal solid waste in Fujian are as follows: kitchen waste 44.76%, paper 13.96%, rubber 25.87%, textiles (fibers) 6.57%, wood and bamboo 3.29%, ash and soil 0%, bricks, tiles and ceramics 1.44%, glass 1.36%, metals 1.39%, others 1.37%. Moisture content: 56. 51%, higher heating value 8627.63 kJ/kg, lower heating value 6667.68 kJ/kg.
Municipal waste incineration produces 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, with fly ash treated by solidification at a 1:1 ratio with cement. The average thermal efficiency for waste heat electricity generation is taken as 22%; in the waste heat heating process, no different forms of heat and energy conversion are involved, leading to higher thermal efficiency, with an average value of 64%. By integrating the thermal efficiencies of both waste heat electricity generation and direct heating processes, 15% of the heat generated from waste incineration is used for electricity generation, while 56% is utilized 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.
