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 Yunnan are as follows: kitchen waste 50.65%, paper 13.98%, rubber 17.04%, textiles (fibers) 5.16%, wood and bamboo 6.68%, ash and soil 0%, bricks, tiles, and ceramics 0.32%, glass 4.02%, metals 1.26%, others 0%. Moisture content: 57. 0.03%, higher heating value 7089.1 kJ/kg, lower heating value 5179.22 kJ/kg.\n\nMunicipal waste incineration generates 0.205 kg of slag per kg of this waste and 0.05 kg of fly ash and slag, after recovery of precious metals, are landfilled, with fly ash being solidified at a 1:1 ratio with cement. The average thermal efficiency of waste heat electricity generation is assumed to be 22%; in the waste heat utilization process for heating, 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 both waste heat electricity generation and direct heat supply processes, 15% of the heat generated during waste incineration is used for electricity generation, and 56% is used 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.
