The dataset represents the average \"municipal solid waste, incineration, Not specified\" treatment situation in the southwestern region of China, which includes Chongqing, Sichuan, Guizhou, Yunnan, and Tibet. The waste treatment activities are based on an average urban/public waste mixture and are not suitable for single specific waste materials such as plastics, paper, cardboard, etc. If your waste consists of a specific waste mixture, please individually account for the corresponding waste. For every kg of this waste, 0.205kg of slag and 0. Fly ash and slag, after recovery of precious metals, are landfilled, with fly ash being solidified with cement at a ratio of 1:1. The average thermal efficiency of waste heat power generation is taken as 22%; during the process of waste heat supply, there is no conversion between different forms of heat and energy, and the thermal efficiency is higher, taken as an average of 64%; by combining the thermal efficiencies of the integrated waste heat power generation process and the direct heat supply process, 15% of the heat generated during waste incineration is used for power generation, and 56% is used for direct heating. This dataset is calculated based on the Urban and Rural Development Statistics Yearbook, which focuses on urban appearance and environmental sanitation in this region.
