The dataset represents the average \"municipal solid waste, incineration with heat recovery\" treatment situation in the southwestern region of China, which includes: Chongqing, Sichuan, Guizhou, Yunnan, and Tibet.\\nWaste 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 inventory the corresponding wastes separately. For every kg of this waste, 0.205kg of slag and 0. The fly ash and slag, after recovery of precious metals, are landfilled at a ratio of 1:1 with cement for solidification treatment. During the waste heat supply process, there was no conversion of heat and energy in different forms, the thermal efficiency is relatively high, with an average value of 64%. This dataset calculates the situation in this area based on the statistics of urban and rural construction - urban appearance and environmental hygiene.
