The plastic recycling process generally consists of several stages. Here is a detailed explanation:
Collection: First, the plastic must be properly collected. This may involve separating the plastic from other materials in recycling bins or separate collection at specific collection points.
Sorting: Once collected, plastic is sorted according to its type. Different types of plastic have different properties and therefore need to be processed separately. Plastics are sorted into categories such as PET, HDPE, PVC, LDPE, PP, among others.
Shredding: After sorting, the plastic is shredded into small pieces or reduced to flakes. This facilitates further processing.
Washing: The shredded plastic is then washed to remove any residue or contaminants. This may include the use of water and detergents to ensure that the plastic is clean and ready for further processing.
Melting and extrusion: The washed plastic is melted in an oven and turned into a viscous liquid. It is then extruded through a nozzle to form plastic threads or sheets.
Granulation: The plastic threads or sheets are cut into small granules, also known as pellets. These pellets are easier to handle and are used as raw material in the manufacture of new plastic products.
Manufacture of new products: Finally, recycled plastic granules are used to manufacture a wide variety of products, such as packaging, bottles, pipes, toys, furniture and many more.
