Description
This dataset represents the disposal 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 Hubei are as follows: kitchen waste 55.3%, paper 1.5%, rubber 4.5%, textiles (fibers) 0%, wood and bamboo 8.3%, ash and soil 0%, bricks, tiles and ceramics 27.3%, glass 2%, metals 1.1%, others 0%. Moisture content is 53.5%, and the higher heating value is 4550. 7 kJ/kg, lower heating value 2783.55 kJ/kg.
Municipal waste incineration produces 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; fly ash is solidified with cement at a ratio of 1:1. The average thermal efficiency for waste heat electricity generation is assumed to be 22%; during waste heat district heating, no different forms of heat and energy conversion are involved, thus the thermal efficiency is relatively high, with an average value of 64%. By integrating electricity generation and direct heating processes, 15% of the heat generated from waste incineration is used for electricity generation, and 56% is used for direct heating.
The proportions of waste incineration conditions are 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.
