The dataset represents the average \"municipal solid waste, incineration, thermal\" treatment in the northwest region of China, which includes: Shaanxi, Gansu, Qinghai, Ningxia, and Xinjiang. The waste treatment activities are based on an average urban/public waste mixture and are not suitable for single specific waste types such as plastics, paper, cardboard, etc. If your waste is a specific waste mixture, please separately account for the corresponding waste. For every kg of this waste, 0.205kg of slag and 0. The fly ash and slag, at a weight of 0.5kg, are landfilled after precious metal recovery. The fly ash is treated with cement at a ratio of 1:1 for solidification. During the process of supplying residual heat, there was no conversion of heat and energy in different forms, resulting in a relatively high thermal efficiency, with an average value of 64%. This dataset is calculated based on the urban and rural development statistical yearbook - provincial urban sanitation and environmental hygiene for the situation within this region.
