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. Not suitable for representing any single specific waste type, such as plastics, paper, or cardboard. The composition of municipal solid waste in the Xizang Autonomous Region are as follows: kitchen waste 57%, paper 6%, rubber 12%, textiles (fibers) 7%, wood and bamboo 14%, ash and soil 0%, bricks, tiles and ceramics 3%, glass 0%, metals 1%, others 0%. Moisture content is 47%, gross calorific value is 7185.47 kJ/kg, and net calorific value is 5196. 19 kJ/kg.
Municipal waste incineration produces 0.205 kg of bottom ash per kg of this waste and 0.05 kg of fly ash: after precious metal recovery from fly ash and slag, they are landfilled, and fly ash is solidified at a 1:1 ratio with cement. The average thermal efficiency for waste heat electricity generation is 22%; during the waste heat heating process, without different forms of heat and energy conversion, the thermal efficiency is relatively high, with an average value of 64%. By integrating the thermal efficiencies of both waste heat electricity generation and direct heating processes, 15% of the heat generated from waste incineration is used for electricity generation, and 56% is utilized for direct heating.
The proportion of waste incineration 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.
