The dataset represents the average \"municipal solid waste, incineration, thermal\" treatment situation in the Northeastern region of China, which includes the provinces of Liaoning, Jilin, and Heilongjiang. The waste treatment activity is based on an average urban/public waste mixture and is not suitable for specific waste types such as plastics, paper, cardboard, etc. If your waste consists of a specific waste mixture, please inventory the corresponding waste separately. For each kg of this type of waste, 0.205 kg of slag and 0. The fly ash and slag, at 0.5 kg each, after the recovery of precious metals, are landfilled. The fly ash is solidified with cement at a ratio of 1:1. During the residual heat supply process, there were no conversions of heat and energy in different forms, so the thermal efficiency is high, 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 in this area.
