Description
This dataset represents the treatment mix (technology mix) for "municipal solid waste, municipal incineration." The recommended use of this dataset is for average municipal/public waste mixtures. It is not suitable for representing any single specific waste type, such as plastics, paper, or cardboard. The composition of municipal solid waste in Guizhou is as follows: kitchen waste 62.57%, paper 10.28%, rubber 9.84%, textiles (fibers) 0.51%, wood and bamboo 7.02%, ash and soil 0.68%, bricks, tiles, and ceramics 2.36%, glass 0.37%, metals 2.24%, other 4.12%. Moisture content 66. 28%, higher heating value 5643.45 kJ/kg, lower heating value 3721.97 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 boiler slag and fly ash, is landfilled and 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 utilization for heating, no different forms of heat and energy conversion occur, resulting in higher thermal efficiency, with an average value of 64%. By integrating the thermal efficiencies of both waste heat electricity generation and direct heat supply, 15% of the heat generated from waste incineration is used for electricity generation, and 56% is utilized for direct heating.
The proportions reflecting waste incineration conditions are estimated based on China's national context.
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.
