Description
This dataset represents a treatment mix (technology mix) for "municipal solid waste, municipal incineration." It is recommended for use with 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 Henan are as follows: kitchen waste 55.02%, paper 5.52%, rubber 3.97%, textiles (fibers) 1.65%, wood and bamboo 1.36%, ash and soil 0%, bricks, tiles, and ceramics 26.67%, glass 1.56%, metals 0.59%, other 3.66%. Moisture content: 55. 81%, higher heating value 4509.38 kJ/kg, lower heating value 2763.77 kJ/kg.
Municipal waste incineration produces 0.205 kg of slag per kg of this waste and 0.05 kg of fly ash: after heavy metal recovery, fly ash and furnace slag are landfilled, with fly ash solidified at a ratio of 1:1 with cement. 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 and energy conversion are involved, resulting in higher thermal efficiency, with an average value of 64%. By comprehensively considering the thermal efficiencies of waste heat electricity generation and direct heat supply, 15% of the heat generated during the waste incineration process is used for electricity generation, while 56% is used for direct heating.
The proportions of waste incineration conditions are estimated based on China's national context.
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.
