The characteristics of municipal solid waste (MSW) processed by the municipal solid waste incinerator (MSWI) in urban areas of Guizhou are as follows: food waste 62.57%, paper 10.28%, rubber 9.84%, textile (fiber) 0.51%, wood and bamboo 7.02%, ash and soil 0.68%, bricks, tiles, and ceramics 2.36%, glass 0.37%, metals 2.24%, and others 4.12%. It has a moisture content of 56.97%, higher calorific value of 5643.45 kJ/kg, and lower calorific value of 3721. 97 kJ/kg. Waste treatment activities are based on average urban/public waste mixtures and are not suitable for individual specific waste materials such as plastics, paper, cardboard, etc. If your waste is a specific waste mixture, please inventory the corresponding waste separately. For each kg of this waste, 0.205 kg of slag and 0. The fly ash and slag, in a weight of 05kg, are landfilled after precious metal recovery. The fly ash is solidified with cement in a ratio of 1:1. The average thermal efficiency of waste heat power generation is 22%; during the process of waste heat supply, there are no different forms of heat and energy conversion, and the thermal efficiency is higher, averaging 64%; through the comprehensive thermal efficiency of waste heat power generation and direct heat supply processes, 15% of the heat generated during waste incineration is used for power generation and 56% is used for direct heating.
