Description
This dataset represents the disposal mix (technology mix) for 'municipal solid waste, municipal incineration'. Recommended use of this dataset: 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 Jiangsu are as follows: kitchen waste 62.6%, paper 10.9%, rubber 11.4%, textiles (fibers) 2.1%, wood and bamboo 0.9%, ash and soil 0%, bricks, tiles, and ceramics 0.7%, glass 2%, metals 0.2%, others 9.2%. Moisture content is 60.7%, and higher heating value is 5649. 64 kJ/kg, lower heating value 3757.05 kJ/kg.
Municipal waste incineration generates 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; the fly ash is solidified with cement at a ratio of 1:1. The average thermal efficiency for waste heat electricity generation is 22%; in the waste heat district heating process, where no different forms of heat and energy conversion are involved, the thermal efficiency is higher, 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 from waste incineration is used for electricity generation, and 56% is used 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.
