"waste coke for recycling" refers to coke and its residues that have lost their original functionality due to breakage, pulverization, quality degradation, or end of service life, or although not completely losing their usability, have been discarded during production and utilization processes in industries such as metallurgy, chemical, and energy. After collection, screening, classification, and processing, this type of waste coke can be reused as a metallurgical reductant, fuel supplement, or as raw materials for construction materials and chemical products, thus entering the resource recycling phase.
