The characteristics of urban solid waste processed by Tianjin's Municipal Solid Waste Incinerator (MSWI) are as follows: food waste 56.9%, paper 15.3%, rubber 16.9%, textiles (fibers) 3.9%, wood and bamboo 1.6%, ash and soil 0%, bricks, tiles, and ceramics 2.9%, glass 1.6%, metals 0.7%, and other 0%. It has a moisture content of 56.11%, higher heating value of 7021.52 kJ/kg, and lower heating value of 5046. 26 kJ/kg. Waste treatment activities are based on an average urban/public waste mixture and are not suitable for single specific waste materials like plastic, paper, cardboard, etc. If your waste is a specific mixture, please inventory the corresponding waste separately. Each kg of this waste produces 0.205 kg of slag and 0. The fly ash and furnace slag, after precious metal recovery, are landfilled. The fly ash is solidified with cement at a ratio of 1:1. The average heat efficiency of waste heat power generation is 22%; the waste heat supply process does not involve different forms of heat and energy conversion, so its heat efficiency is quite high, averaging 64%; through a comprehensive analysis of the thermal efficiency of waste heat power generation and direct heat supply, 15% of the heat generated during waste incineration is used for power generation and 56% is used for direct heating.
