Understanding the PET Recycling Landscape
The Global Plastic Waste Crisis
PET (polyethylene terephthalate) dominates packaging and textile industries, yet less than 30% is effectively recycled. Landfills and incineration release toxic emissions, while ocean pollution threatens ecosystems. A professional PET recycling line addresses these issues by transforming waste into reusable resources, aligning with global circular economy goals.
Key Challenges in PET Recycling
Contamination: Mixed materials (labels, adhesives, PVC) reduce recyclate purity.
Energy Intensity: Traditional recycling consumes excessive power during washing and extrusion.
Quality Loss: Thermal degradation lowers material performance, limiting reuse potential.
How a PET Recycling Line Works: A Problem-Solving Approach
Step 1 – Intelligent Sorting & Pre-Treatment
Challenge: Manual sorting is inefficient and error-prone.
Solution:
AI-powered optical sorters automatically separate PET from contaminants (metals, PVC) with precision.
Grinding systems reduce bulk PET into uniform flakes for consistent processing.
Step 2 – Deep Cleaning & Decontamination
Challenge: Residual pollutants compromise food-grade safety.
Solution:
Multi-stage washing removes oils, adhesives, and microbes.
Closed-loop water systems minimize freshwater consumption by 60%.
Step 3 – Extrusion & Pelletizing
Challenge: Thermal degradation reduces PET’s intrinsic viscosity (IV).
Solution:
Controlled-temperature extrusion preserves material integrity.
Advanced pelletizing ensures uniform size and smooth surfaces for downstream manufacturing.
Step 4 – Quality Assurance & Packaging
Challenge: Inconsistent pellet quality disrupts production.
Solution:
Automated screening removes defective pellets.
Moisture-proof packaging maintains product integrity during storage.
