Navigating the landscape of recycled content certifications can be challenging. This guide explains the key differences between GRS, ISCC PLUS, and UL 2809 for PCR polycarbonate sourcing.

- Greenhouse gas calculation methodology
- Risk-based supply chain assessment
Best for: Chemical recycling pathways and EU renewable energy directives compliance.
UL 2809
Scope: Scientific validation of recycled content claims
Key requirements:
- Specific recycled content percentages (ocean-bound, post-consumer, post-industrial)
