Scrap metal refers to discarded or surplus metal materials that are collected for recycling. It includes both ferrous metals, such as steel and iron, and non-ferrous metals, such as aluminum, copper, and brass. Scrap metal is generated from various industries, including construction, automotive, and manufacturing. Once collected, it is sorted, cleaned, and melted down for reuse in the production of new products. Recycling scrap metal reduces the need for mining raw materials, conserves natural resources, and lowers energy consumption. This process plays a significant role in environmental sustainability, reducing waste and supporting the circular economy.
