'''Scrap''' consists of [[Recycling|recyclable]] materials, usually metals, left over from product manufacturing and consumption, such as parts of vehicles, building supplies, and surplus materials. Unlike [[waste]], scrap can have [[Waste valorization|monetary value]], especially recovered [[metal]]s, and non-metallic materials are also recovered for recycling. Once collected, the materials are sorted into types – typically metal scrap will be crushed, shredded, and sorted using mechanical processes.
Scrap recycling maybemay be important for creating a more [[sustainable economy]] or creating a [[circular economy]], may use less energy, the scrap recycling industry can be a source of employment, from collection and processing to manufacturing using recycled materials and may have less environmental impact than producing metal from [[ore]]. Metal recycling, especially of [[structural steel]], [[Ship breaking|ships]], used manufactured goods, such as [[Vehicle recycling|vehicles]] and [[white goods]], is an industrial activity with complex networks of [[wrecking yard]]s, sorting facilities, and recycling plants. The industry includes both formal organizations and a wide range of informal roles such as [[waste picker]]s who help sorting through scrap.
