Description
This dataset represents the treatment 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 plastic, paper, or cardboard. The composition of municipal solid waste in Hunan are as follows: kitchen waste 25.71%, paper 18.27%, rubber 22.26%, textiles (fibers) 11.24%, wood and bamboo 2.33%, ash and soil 11.16%, bricks, tiles, and ceramics 1.77%, glass 2.37%, metals 2.03%, others 2.86%. Moisture content: 52. 39%, with a higher heating value of 8525.15 kJ/kg and a lower heating value of 6747.63 kJ/kg.
Municipal waste incineration produces 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, with fly ash 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 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% 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.
