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 plastics, paper, or cardboard. The composition of municipal solid waste in Hebei is as follows: kitchen waste 44.56%, paper 13.06%, rubber 11.11%, textiles (fibers) 0.24%, wood and bamboo 28.07%, ash and soil 0%, bricks, tiles and ceramics 0.76%, glass 1.79%, metal 0.42%, other 0%. Moisture content: 53. 96%, higher heating value 7715.05 kJ/kg, lower heating value 5778.27 kJ/kg.
Municipal waste incineration produces 0.205 kg of slag per kg of this waste and 0.05 kg of fly ash; after recovery of precious metals from fly ash and slag, they are landfilled, and fly ash is solidified with cement at a ratio of 1:1. The average thermal efficiency for waste heat electricity generation is taken as 22%; since no different forms of heat and energy conversion are involved in the waste heat heating process, the thermal efficiency is relatively high, with an average value of 64%. By integrating the thermal efficiencies of waste heat electricity generation and direct heating, 15% of the heat generated from waste incineration is used for electricity generation, and 56% is used for direct heating.
The proportions regarding waste incineration conditions are estimated based on China's national circumstances.
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.
