Scrap metal arises from various origins, including industrial activities, construction debris, waste management operations, and domestic refuse. To address issues of contamination or impractical transport sizes, scrap processors have developed methods to purify or enhance the scrap, such as shredding, granulating, and compacting. These processes render the scrap more suitable for end-users, primarily foundries that produce alloys, remelted metals, or semi-finished goods like sheets, hardware, wires, and, in the case of lead, components for batteries and paint. In the copper scrap market, refineries often recycle lower-grade materials to produce new copper cathodes, initiating a new cycle of use and production.
