The dataset represents the average \"municipal solid waste, incineration at unspecified landfills\" treatment situation in the northwestern region of China, which includes: Shaanxi, Gansu, Qinghai, Ningxia, and Xinjiang. The waste management activities are based on an average urban/public waste mixture and are not suitable for specific waste types 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, it produces 0.205 kg of slag and 0.  Fly ash and furnace slag, after the recovery of precious metals, are landfilled. Fly ash is solidified with cement at a ratio of 1:1. The average thermal efficiency of waste heat power generation is 22%. The waste heat supply process does not involve the conversion between different forms of heat and energy, thus the thermal efficiency is relatively high, with an average of 64%. Through the comprehensive thermal efficiency of waste heat power generation and direct heat supply processes, 15% of the heat generated from waste incineration is used for power generation, and 56% is used for direct heating. This dataset is calculated according to the \"Urban and Rural Development Statistics Yearbook - Sanitation of Cities by Province\" for the situation in this area.
