Description
This dataset represents the disposal 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 plastic, paper, or cardboard. The composition of municipal solid waste in Sichuan are as follows: kitchen waste 50.09%, paper 15.54%, rubber 12.63%, textiles (fibers) 2.34%, wood and bamboo 7.78%, ashes and soil 0.32%, bricks, tiles, and ceramics 1.42%, glass 0.09%, metals 0.8%, others 0%. Moisture content 64. 86%, higher heating value 5930.68 kJ/kg, lower heating value 4117.5 kJ/kg.
Municipal waste incineration generates 0.205 kg of slag per kg of this waste and 0.05 kg of fly ash: after recovery of precious metals from fly ash and slag, they are landfilled; 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, there is no conversion between different forms of heat and energy, so the thermal efficiency is relatively high, with an average value of 64%. By comprehensively considering the thermal efficiencies of the waste heat electricity generation process and the direct heating process, 15% of the heat generated during the waste incineration process is used for electricity generation, and 56% is used 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.
