FAQ

What's the difference between PCR and PIR recycled resins?
PCR (Post-Consumer Recycled) comes from end-use consumer products like bottles and packaging, while PIR (Post-Industrial Recycled) comes from manufacturing waste streams. PCR typically commands higher sustainability value but may have more contamination challenges.
How do I verify recycled content claims in plastic resins?
Look for third-party certifications from organizations like SCS Global Services or UL. These provide chain-of-custody documentation and independent verification of recycled content percentages. Avoid relying solely on supplier self-declarations.
Can recycled plastic resins be used in food packaging applications?
Only specific grades of recycled resins with FDA Letters of No Objection or equivalent approvals can be used for direct food contact. Food-grade rPET is the most common, while recycled HDPE and PP have limited food-contact applications.
Why do recycled resins cost more than virgin materials?
Recycled resins require additional collection, sorting, cleaning, and processing steps compared to virgin production. Limited supply, growing demand for sustainable materials, and certification costs also contribute to premium pricing.
How can I minimize contamination issues with recycled resins?
Work with suppliers who provide detailed contamination specifications, implement incoming material inspection protocols, and consider using PIR grades which typically have lower contamination levels than PCR materials.
