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 plastic, paper, or cardboard. The composition of municipal solid waste in Guangdong is as follows: kitchen waste 35.66%, paper 15%, rubber 29.8%, textiles (fibers) 8.6%, wood and bamboo 5.39%, ash and soil 0.42%, bricks, tiles and ceramics 0.76%, glass 1.98%, metals 1.6%, and others 0.8%. Moisture content: 53. 12%, higher heating value 9431.59 kJ/kg, lower heating value 7491.65 kJ/kg.
Municipal waste incineration produces 0.205 kg of slag per kg of this waste and 0. 0.5 kg of fly ash and slag, after precious metal recovery, are landfilled, with fly ash being 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 heating process, no different forms of heat and energy conversion occur, resulting in relatively high thermal efficiency, with an average value of 64%. By comprehensively considering the thermal efficiencies of the waste heat electricity generation and direct heating processes, 15% of the heat generated during waste incineration is used for electricity generation, and 56% for direct heating.
The proportions related to waste incineration 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.
