The characteristics of municipal solid waste (MSW) processed by municipal solid waste incinerators (MSWI) in Guangdong urban areas are as follows: food waste 35.66%, paper 15%, rubber 29.8%, textiles (fibers) 8.6%, wood and bamboo 5.39%, ash and soil 0.42%, bricks, tiles, and ceramics 0.76%, glass 1.98%, metals 1.6%, and others 0.8%. The moisture content is 50.61%, the higher calorific value of 9431.59 kJ/kg, and the lower calorific value of 7491. 65 kJ/kg. Waste treatment activities are based on an average urban/municipal waste mixture 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 this type of waste, 0.205 kg of slag and 0 (the sentence seems incomplete, as there is information missing after the last \"and 0.\") is produced per kg. The fly ash and slag, after precious metal recovery, are landfilled, with a weight of 05kg. The fly ash is treated by solidification with cement at a ratio of 1:1. The average heat efficiency of waste heat power generation is taken as 22%; in the process of waste heat supply, there is no conversion of different forms of heat and energy, so the heat efficiency is higher, taken as an average of 64%; by comprehensively considering the thermal efficiency of waste heat power generation and direct heat supply, 15% of the heat generated during the waste incineration process is used for power generation, and 56% is used for direct heating.
