Zeefier’s commitment to sustainability goes beyond using seaweed as our raw material. We also align with internationally recognised textile safety and environmental frameworks that help brands and dyehouses make compliant choices with confidence.
We’re proud to share that Zeefier is certified under OEKO-TEX® ECO PASSPORT—the OEKO-TEX® system for chemicals, colourants and auxiliaries that are tested for harmful substances and assessed against strict criteria.
What ECO PASSPORT is
OEKO-TEX® ECO PASSPORT is designed to support safer chemistry in textile supply chains. It verifies that certified chemical products meet defined limit values for harmful substances and helps professional users select inputs that fit with responsible production requirements.
Why this matters for brands
For brands, ECO PASSPORT helps you:
-
De-risk material choices with a widely recognised, third-party standard for chemical inputs.
-
Strengthen compliance documentation for restricted substance lists and customer requirements.
-
Back up sustainability and safety claims with credible certification data—without overpromising.
Why this matters for dyehouses and mills
For dyehouses and mills, ECO PASSPORT supports:
-
Faster qualification of new dye systems, with clearer documentation on chemical safety and limit values.
-
Smoother communication with brand customers, especially where certification-aligned chemistry is requested.
-
A more robust chemical management approach, without changing machinery or standard operating processes.
Where Zeefier fits in
Zeefier develops industrial textile dyes made from 100% seaweed, sourced from local European side streams. Our dyes are designed to run in existing dyehouse set-ups and can be applied across a wide range of textiles and fibre blends, depending on the application and process parameters.
ECO PASSPORT certification supports what we aim to deliver: colour that is innovative, traceable, and ready for industrial supply chains.
If you’re a brand exploring certified biobased colour, or a dyehouse interested in trialing seaweed dyes in production conditions, we’d like to speak.
