Description
This dataset represents the treatment 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 Chongqing are as follows: kitchen waste 59.2%, paper 10.1%, rubber 16%, textiles (fibers) 6.1%, wood and bamboo 4.2%, ash and soil 0%, bricks, tiles, and ceramics 0%, glass 3.4%, metals 1.1%, and others 0%. Moisture content is 64.1%, and the higher heating value is 6764. 49 kJ/kg, lower heating value 4797.86 kJ/kg.
Municipal waste incineration produces 0.205 kg of slag per kg of this waste and 0.05 kg of fly ash is landfilled after recovery of precious metals from fly ash and slag; the fly ash is solidified with cement at a ratio of 1:1. The average thermal efficiency of waste heat electricity generation is 22%; in the waste heat heating process, no different forms of heat and energy conversion are involved, resulting in higher thermal efficiency, which is taken as an average of 64%. By considering the combined thermal efficiencies of waste heat electricity generation and direct heating processes, 15% of the heat generated from waste incineration is used for electricity generation and 56% for direct heating.
The proportion of waste incineration scenarios is 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.
