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 Gansu is as follows: kitchen waste 36.38%, paper 9.7%, rubber 11.34%, textiles (fibers) 2.1%, wood and bamboo 1.36%, ash and soil 0%, bricks, tiles and ceramics 37.81%, glass 0.93%, metals 0.23%, other 0%. Moisture content is 44. 26%, with a higher heating value of 6088.2 kJ/kg and a lower heating value of 4390.57 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 precious metal recovery from fly ash and slag, with the fly ash solidified at a 1:1 ratio with cement. The average thermal efficiency for waste heat electricity generation is taken as 22%; in the waste heat district heating process, where no different forms of heat and energy conversion occur, the thermal efficiency is higher, with an average value of 64%. By integrating the thermal efficiencies of both the 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 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.
