Recycled Content Documentation: Meeting EU Transparency Standards for Textiles

Why Recycled Content Documentation Matters

Recycled content is one of the key information requirements expected for textile Digital Product Passports. Under the ESPR framework, products sold in the EU will likely need to declare the percentage of recycled materials they contain—with verifiable documentation.

For textile exporters, this means going beyond marketing claims. You'll need structured, certified, and auditable data about the recycled content in your products.

Understanding Recycled Content Types

Not all recycled content is equal in the eyes of EU regulation. Understanding the distinctions is critical:

Pre-Consumer Recycled Content

Material diverted from the waste stream during the manufacturing process. This includes:

• Cutting waste from garment factories that's re-processed into fibre
• Yarn waste from spinning mills
• Off-specification production materials

Post-Consumer Recycled Content

Material collected after consumer use. This typically includes:

• Collected clothing items mechanically recycled into new fibres
• PET bottles chemically recycled into polyester yarn
• Other end-of-life textile products processed into raw materials

EU requirements are expected to distinguish between these types, as post-consumer recycling generally has higher environmental impact value.

Certification Standards

Claims about recycled content typically need to be backed by recognized certification:

• GRS (Global Recycled Standard) — the most widely recognized standard for recycled content. Verifies recycled input, chain of custody, and social/environmental practices
• RCS (Recycled Claim Standard) — tracks recycled content through the supply chain with chain-of-custody verification, without the social/environmental requirements of GRS
• OEKO-TEX Made in Green — combines product safety testing with facility certification, can include recycled content claims
• EU Ecolabel — the EU's own environmental label, which may include recycled content criteria for textiles

What Documentation You Need

For each product claiming recycled content, you should maintain:

1. Transaction certificates (TC) — issued by the certification body for each purchase of certified recycled material
2. Scope certificates (SC) — proving your supplier's certification is valid and in scope
3. Material composition breakdown — showing exactly which components contain recycled content
4. Percentage calculations — clear calculation methodology for overall recycled content percentage
5. Chain of custody records — documenting the flow of recycled materials through your supply chain

How to Calculate Recycled Content Percentage

The calculation depends on your product structure:

Single-Component Products

For a product made from a single fabric, the calculation is straightforward:

Recycled content % = (Weight of recycled fibre / Total weight of fibre) × 100

Multi-Component Products

For products with multiple components (main body, lining, trim), you need to calculate per-component and then derive the overall percentage based on weight proportions.

Use epassportify's Material Composition Calculator to validate your calculations and generate DPP-ready output formats.

Structuring Data for DPP

Your recycled content data needs to be in a format that can be included in a Digital Product Passport. This means:

• Component-level detail — recycled content percentage for each product component
• Content type classification — pre-consumer vs. post-consumer
• Certification references — certificate numbers and validity dates
• Material source — general description of recycled input source (e.g., "mechanically recycled post-consumer cotton")

Platforms like epassportify structure this data automatically when you enter your material composition, linking recycled content to the correct certification records.

Common Challenges

• Blended materials — when recycled and virgin fibres are blended, tracking percentages requires careful documentation at the yarn or fabric stage
• Supplier inconsistency — different suppliers may use different calculation methods; standardize your approach
• Certificate timing — certificates have validity periods; ensure your documentation is current
• Multi-tier supply chains — recycled content often enters at Tier 2 or 3; supply chain mapping is essential
