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 the Xinjiang Uygur Autonomous Region are as follows: kitchen waste 76%, paper 2.4%, rubber 5.4%, textiles (fibers) 4.2%, wood and bamboo 2.5%, ash and soil 0%, bricks, tiles, and ceramics 6.4%, glass 2.4%, metals 0.8%, and others 0%. Moisture content is 47%, and the higher heating value is 4148. 64 kJ/kg, lower heating value 2183.4 kJ/kg.
Municipal waste incineration produces 0.205 kg of slag per kg of this waste and 0.05 kg of fly ash; after precious metal recovery from fly ash and bottom ash, they are landfilled, with fly ash being solidified at a 1:1 ratio with cement. The average thermal efficiency of waste heat electricity generation is 22%; in the waste heat utilization process for heating, since no different forms of heat and energy conversion occur, the thermal efficiency is higher, with an average value of 64%. By integrating the thermal efficiency of both waste heat electricity generation and direct heat supply processes, 15% of the heat generated from waste incineration is used for electricity generation, and 56% is used 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.
