Businesses involved in recycling metal waste and scrap collect, buy, sort and process unwanted metal so it can be reused as a material. They may handle ferrous metals, such as iron and steel, and non-ferrous metals, including aluminium, copper, brass and lead. Sources can include household items, building and demolition waste, manufacturing offcuts, vehicles and redundant machinery. Typical services include scrap collection, skip or container provision, site clearance, metal separation and preparation for onward processing. Depending on the material and equipment available, this can involve weighing, grading, dismantling, cutting, baling or shredding. Recyclers may supply prepared metal to foundries, smelters and other manufacturers, where it can be melted and made into new products. Some businesses also accept specific items such as cables, appliances or vehicle parts, subject to their facilities and waste-handling arrangements.
