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 Shaanxi are as follows: kitchen waste 38.6%, paper 9.3%, rubber 10.1%, textiles (fibers) 1.4%, wood and bamboo 7.4%, ash and soil 0%, bricks, tiles, and ceramics 23.3%, glass 6.5%, metals 3.4%, others 0%. Moisture content is 46.1%, and higher heating value is 5445. 04 kJ/kg, lower heating value 3802.42 kJ/kg.
Municipal waste incineration generates 0.205 kg of slag per kg of this waste and 0.05 kg of fly ash: after heavy metal recovery from fly ash and slag, they are landfilled; 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%; during waste heat utilization for heating, no different forms of heat and energy conversion occur, thus the thermal efficiency is relatively high, taken as an average of 64%. By comprehensively considering the thermal efficiencies of both waste heat electricity generation and direct heating processes, 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 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.
