Description
This dataset represents the disposal 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 Hainan are as follows: kitchen waste 58.42%, paper 6.44%, rubber 11.93%, textiles (fibers) 0.89%, wood and bamboo 1.6%, ash and soil 0%, bricks, tiles and ceramics 12.92%, glass 0.53%, metals 0.68%, others 6.47%. Moisture content: 55. 81%, higher heating value 5556.5 kJ/kg, lower heating value 3706.33 kJ/kg.
Municipal solid waste incineration generates 0.205 kg of slag per kg of such waste and 0.05 kg of fly ash is landfilled after precious metal recovery from fly ash and slag; the ash is solidified with cement at a ratio of 1:1. The average thermal efficiency for waste heat electricity generation is assumed to be 22%. In the waste heat district heating process, no different types of heat or energy conversion occur, so the thermal efficiency is relatively high, taken as the average of 64%. By integrating the thermal efficiencies of both the electricity generation and direct heating processes, 15% of the heat generated in the waste incineration process is used for electricity generation and 56% for direct heating.
The estimated proportions of waste incineration are based on China's national context.
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.
