Bio-based dyes have reached their inflection point.
Claessen Blue™ is now produced through stable fermentation, runs effortlessly on mill equipment, and has achieved cost competitiveness with synthetic indigo — a milestone once thought distant.
Our definition of clean color is factual, not abstract:
• batch-level digital traceability
• a verifiable hangtag system
• a TÜV-verified LCA confirming ultra-low toxicity
A more transparent, science-driven color ecosystem is accelerating.
We welcome partners who are ready to build it together.
