Primary recycling involves process scrap, or a single clean waste type. An important sub-class of primary recycling is known as "Closed loop recycling" in which polymer from a single product or product type is collected and recycled in-to the same product. Polypropylene from battery cases is a well established example.[5]
Secondary recycling uses reclaimed post consumer materials as a source of material for new products. Tertiary recycling involves chemical breakdown of materials which are then re-utilised further back in the feedstock chain. Quaternary recycling is often termed energy from waste.
