The term "Zinc scrap" here refers to metallic zinc and zinc-containing materials that have lost their original functionality due to loss, breakage, substandard quality, or end-of-life during metallurgical, chemical, machining, and product use processes, or that, although not entirely devoid of utility, have been discarded. Such waste zinc can be reprocessed through collection, classification, shredding, and smelting, and then recycled as zinc resources for electrolytic zinc production, alloy manufacturing, chemical raw materials, or other recycling applications.
