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. It is not suitable for representing any single specific waste type, such as plastic, paper, or cardboard. The composition of municipal solid waste in Liaoning are as follows: kitchen waste 53.07%, paper 11.86%, rubber 14.77%, textiles (fibers) 7.13%, wood and bamboo 9.33%, ash and soil 0%, bricks, tiles, and ceramics 0%, glass 3.22%, metals 0.61%, other 0%. Moisture content 57. 71%, higher heating value 7299.41 kJ/kg, lower heating value 5344.98 kJ/kg.
Municipal waste incineration generates 0.205 kg of slag per kg of this waste and 0. 0.5 kg of fly ash is landfilled after precious metal recovery from fly ash and slag, with fly ash being solidified at a 1:1 ratio with cement. The average thermal efficiency for waste heat electricity generation is 22%; in the waste heat heating process, no different forms of heat and energy conversion are involved, resulting in higher thermal efficiency, with an average value of 64%. By integrating 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 of 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.
