Businesses in the waste and scrap sector collect, sort, process and manage unwanted materials from households, businesses, building projects and industrial sites. Services may include scheduled or one-off collections, skip or container hire, site clearances and the handling of particular waste streams. Some firms arrange onward transport and treatment, while others operate recycling or recovery facilities. Scrap businesses typically buy, collect or process materials such as ferrous and non-ferrous metals, machinery, vehicles, cables and electronic equipment. Materials may be graded, dismantled, baled or prepared for recycling and reuse. Waste firms may also handle wood, paper, plastics, glass, green waste, soil or construction debris, depending on their facilities and permissions. Customers can expect advice on separating materials and information about collection arrangements and the types of waste accepted; hazardous or specialist waste may require separate handling.
