What is the Process of Recycling Plastic?
Plastic recycling is the process of converting waste plastic into new and useful materials. It involves several steps, including:
- Collection: Plastic waste is collected from various sources, such as households, businesses, and recycling centers.
- Sorting: Different types of plastic are sorted based on their resin identification code (RIC).
- Cleaning: Plastic waste is cleaned to remove impurities such as food residue and paper labels.
- Shredding: Collected plastic is shredded into small pieces to facilitate further processing.
- Melting: Shredded plastic is melted into a molten state.
- Extrusion: The molten plastic is extruded into various shapes, such as pellets, fibers, or sheets.
- Processing: The extruded plastic may undergo additional processing steps, such as molding, forming, or 3D printing.
- Production: The recycled plastic is then used to manufacture new products, such as bottles, containers, and clothing.
