Recycled Content Certifications: GRS, RCS, OBP and Your Digital Product Passport
A practical guide to choosing the right recycled content certification and connecting verification data to your ESPR-compliant Digital Product Passport.
- **GRS vs RCS**: Global Recycled Standard covers social and environmental criteria; Recycled Claim Standard focuses purely on content verification
- **Minimum thresholds**: GRS requires ≥20% recycled content; RCS has no minimum but tracks exact percentages
- **Ocean plastics**: OBP (Ocean Bound Plastic) certification addresses a specific waste stream with growing consumer recognition
- **Chain of custody**: All major certifications use transaction certificates that map directly to DPP data requirements
- **ESPR alignment**: Article 8 of the ESPR mandates recycled content disclosure — third-party certification provides the audit trail regulators expect
The Ecodesign for Sustainable Products Regulation (ESPR) will require fashion brands to disclose recycled content percentages in their Digital Product Passports. But a number on a label means nothing without verification. Third-party certifications provide the chain of custody documentation that transforms marketing claims into regulatory compliance.
This guide breaks down the three most relevant certifications for textile recycled content, what they require operationally, and how their data flows into your DPP.
The Certification Landscape#
Full supply chain
Social + environmental
Min. 20% recycled
Content tracking only
No social audit
Any % recycled

Impact narrative
Global Recycled Standard (GRS)#
Managed by Textile Exchange, GRS is the most comprehensive certification for recycled textiles. As of 2023, over 7,400 facilities held GRS certification globally (Textile Exchange, 2024).
GRS verifies not just recycled content but also:
- Chemical use restrictions aligned with ZDHC MRSL
- Social compliance (wages, working hours, health and safety)
- Environmental management systems at each facility
The 20% threshold matters. Products must contain at least 20% certified recycled material to carry the GRS label, though transaction certificates can track any percentage for internal reporting.
| Requirement | GRS Specification |
|---|---|
| Minimum recycled content | 20% for consumer label |
| Chain of custody | Full supply chain certification |
| Social audit | Required (annual) |
| Chemical management | ZDHC MRSL alignment |
| Certification body | Accredited third-party |
| Validity | 1 year, annual surveillance |
Recycled Claim Standard (RCS)#
RCS serves brands that need verified recycled content tracking without the broader social and environmental requirements of GRS. It uses the same chain of custody system and certification bodies.
When to choose RCS over GRS:
- Your suppliers already hold separate social certifications (SA8000, BSCI)
- You need to track recycled content below 20%
- Speed matters — RCS audits are lighter and faster
Both standards generate Transaction Certificates (TCs) at each supply chain step. These TCs contain the exact data points ESPR requires: material composition, recycled percentage, and supplier identification.
Ocean Bound Plastic (OBP)#
OBP certification, managed by Control Union, addresses plastic collected within 50km of coastlines in regions without adequate waste management. In 2023, certified OBP collection reached 45,000 tonnes globally (Control Union, 2024).
For fashion brands using recycled polyester, OBP adds a compelling origin story. The certification tracks material from collection through processing, generating documentation that proves plastic was diverted from waterways.
OBP works alongside GRS or RCS — you can hold both for the same product, with OBP verifying origin and GRS/RCS verifying content percentage.
Mapping Certifications to DPP Data Fields#
The draft ESPR implementing acts for textiles specify recycled content as a mandatory disclosure. Here's how certification data maps to likely DPP requirements:
| DPP Data Requirement | Certification Source |
|---|---|
| Recycled content % | Transaction Certificate |
| Material type (pre/post-consumer) | Scope Certificate + TC |
| Supplier facility ID | Certification database |
| Verification date | TC issue date |
| Certifying body | TC header |
| Standard version | Scope Certificate |
Transaction Certificates are issued digitally and include unique identifiers. This makes them ideal for DPP integration — they're already structured data, not PDF scans requiring manual extraction.
Operational Requirements#
Getting certified involves more than paperwork. Each facility in your supply chain handling recycled material must:
- Segregate materials — physical separation of recycled and virgin inputs
- Maintain mass balance records — documented tracking of inputs vs. outputs
- Submit to annual audits — on-site verification by accredited bodies
- Issue Transaction Certificates — for each shipment of certified material
Lead time from audit to certification typically runs 4-8 weeks. Costs scale with facility size and complexity — expect €2,000-5,000 per facility annually for GRS (Textile Exchange, 2024).
Frequently asked questions
Can I use recycled content claims without certification?
Legally, yes — but the EU Green Claims Directive (expected 2026) will require substantiation for environmental claims. Unverified recycled content claims will likely require the same level of evidence as certification provides, without the recognized label. For DPP compliance, third-party verification creates the audit trail regulators expect.
What if my supplier is certified but I'm not?
You cannot make certified product claims unless your own facility (the brand) is certified. However, you can reference supplier certifications in your DPP as supporting documentation. Many brands start with supplier certification and add their own as ESPR deadlines approach.
How do pre-consumer and post-consumer recycled content differ for compliance?
Both count toward recycled content percentages, but ESPR may require separate disclosure. Pre-consumer (factory scraps) is more readily available; post-consumer (used garments, bottles) carries stronger sustainability messaging. GRS and RCS track both categories separately in Transaction Certificates.
Connecting to Your Digital Product Passport#
Certification data shouldn't live in filing cabinets. The Transaction Certificates your suppliers generate contain machine-readable identifiers designed for system integration.
Trama connects directly to certification databases and supplier documentation systems, pulling verified recycled content data into your DPP automatically. When your GRS-certified supplier issues a Transaction Certificate, that data flows through to the product passport — no manual entry, no transcription errors, no hunting for PDFs during audits.
The result: recycled content claims your customers can verify and regulators can trust.
