- Sorting: Different types of plastic (e.g., PET, HDPE, PVC) are sorted to ensure proper processing.
- Cleaning: Contaminants, such as food residue and paper, are removed from the plastic.
- Shredding: The plastic is shredded into small pieces to increase surface area for processing.
- Washing and rinsing: The shredded plastic is washed and rinsed to remove any remaining contaminants.
- Melting: The clean plastic is melted to create a molten form.
- Extrusion: The molten plastic is extruded into pellets or fibers.
- Pelletizing: The melted plastic is cooled and formed into small pellets.
- Processing: The pellets can be used to manufacture new plastic products, such as bottles, containers, and construction materials.
