PET Bottle Recycling Process Overview

The PET bottle recycling process involves several critical steps to transform used bottles into reusable flakes or granules:

1. Sorting by Color: Separating bottles based on color to maintain material consistency.
2. Label Removal: Using de-labelers to eliminate adhesives and foreign materials.
3. Crushing: Reducing bottles into small pieces via crushers or shredders.
4. Rinsing and Washing: Cleaning flakes to remove contaminants.
5. Separation: Using sink/float tanks to isolate materials by density.
6. Drying: Employing dewatering and thermal dryers to reduce moisture content.
7. Extrusion and Granulation: Melting, plasticizing, and reforming flakes into granules.
8. Injection Molding: Creating new PET products from recycled granules.
