Abstract:Hazard-free and reutilization treatment are still the main directions of solid waste disposal,especially,under the background which achieving "peak carbon dioxide emissions carbon neutral" target,"replacing carbon by waste" is also an important route to reduce carbon emission. However, in current situations, the disposal cost of waste is still high, reutilization of waste is still insufficient, "NOT IN MY BACKYARD" effects is serious. Therefore, the new plot of co-processing metallurgical and urban difficult-to-process solid waste using steel industrial furance, especially sintering and pellitizing process, was presented. A new multi-dimension index system based on material property, energy property, hazardous property, and ecological match law based on best disposal route, should be established. A new co-processing technological route using smelting process, including Fire/Mositure pretreatment method coupling with thermal regulation optimizing, was built. Besides,the conception of reginal intelligent co-processing platform of solid waste based on Big Dipper and Web of Things was shown. The direction guidance and technological reference for co-processing of multi-source solid waste were given.
