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.

Global Recycled Standard (GRS)

Scope: Social and environmental responsibility across the entire supply chain

Key requirements:

• Minimum 20% recycled content
• Environmental and social compliance
• Chain of custody documentation
• Third-party audit by approved certification bodies

Best for: Brands marketing directly to sustainability-conscious consumers.

ISCC PLUS

Scope: Mass balance and chain of custody for bio-based and recycled materials

Key requirements:

• System of mass allocation (physical segregation or book & claim)
• 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)
• Third-party testing and verification
• SCS Global testing methodology

Best for: Companies needing legally defensible recycled content claims.

Topcentral’s Certification Portfolio

Topcentral maintains all three certifications, enabling flexible sourcing options:

Life Cycle Assessment (LCA) is critical for verifying carbon neutrality claims in the recycled plastics industry. Topcentral’s proprietary CLCAL™ Cloud Computing platform delivers precise environmental impact analysis.

The Challenge of Carbon Accounting in rPC

Recycled polycarbonate (rPC) often shows lower carbon footprints than virgin material, but accurate calculation requires considering:

• Collection and transport emissions
• Processing energy consumption
• Chemical recycling energy requirements
• Comparison baseline with virgin PC production
• End-of-life recycling potential

CLCAL™ Platform Capabilities

Topcentral’s cloud computing system provides:

• Real-time carbon tracking: From collection to final product
• Multi-scenario modeling: Comparing recycling vs. incineration vs. landfilling
• ISO 14040/14044 compliance: Following international LCA standards
• Blockchain verification: TCBChain® ensuring data immutability
• Third-party audit support: Generating reports for GRS and ISCC PLUS certification

Key Carbon Metrics

Based on CLCAL™ analysis, Topcentral’s recycled polycarbonate products demonstrate:

• 35-60% carbon reduction compared to virgin PC (varies by grade)
• Energy savings of 40-70% through physical vs. chemical recycling pathways
• Verified ocean-bound plastic credits through SCS Oceancycle® certification

EU CBAM Compliance

With the EU Carbon Border Adjustment Mechanism (CBAM) entering full effect, exporters to Europe need robust carbon documentation. CLCAL™ generates CBAM-compliant carbon reports for Topcentral’s export products.

Technical teams can request CLCAL™-generated LCA summaries for specific product grades.
