Description
This dataset represents the disposal mix (technology mix) for 'municipal solid waste, municipal incineration'. The recommended use of this dataset is 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 Beijing is as follows: kitchen waste 66.2%, paper 10.09%, rubber 13.1%, textiles (fibers) 1.2%, wood and bamboo 3.3%, ashes and soil 0%, bricks, tiles, and ceramics 3.9%, glass 1%, metals 0.4%, and others 0%. Moisture content is 63.3%, and the higher heating value is 5858. 91 kJ/kg, lower heating value 3870.94 kJ/kg.
Municipal waste incineration generates 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; fly ash is solidified with cement at a ratio of 1:1. The thermal efficiency of waste heat electricity generation is taken as the average value of 22%; during 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 considering the thermal efficiency of both the waste heat electricity generation process and the direct heating process, 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 conditions is 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.
