ER Ocean Recherche creates marine‑derived textile materials such as SeiFibre™, SeiYarn™ and SeiShell™ by converting algae, cyanobacteria and seafood shell waste into fibers, yarns and coatings. Their low‑impact, plastic‑free process delivers high‑performance, scalable fabrics that are validated as finished garments for fashion brands, while supporting blue‑carbon initiatives and open collaboration with textile manufacturers.

Problem
Conventional textile production relies heavily on land, water, and fossil-based resources, resulting in high material footprints, waste, and limited scalability for sustainable fashion. Designers and brands struggle to find bio‑based fibers that meet performance, aesthetic, and scalability requirements.
Solution
ER Ocean Recherche develops a portfolio of marine‑derived textile materials—including SeiFibre™, SeiYarn™, and SeiShell™—by converting algae, cyanobacteria, and seafood shells into pigments, fibers, and coatings. The company integrates artistic design validation, turning each new material into a finished garment to demonstrate real‑world performance to fashion partners. Their production process is low‑impact, avoiding water‑intensive, land‑intensive, and energy‑intensive steps while remaining plastic‑free. By partnering with fabric manufacturers, yarn spinners, and fiber producers, they scale the supply of these ocean‑sourced textiles to meet industry demand. The approach also supports blue‑carbon initiatives, contributing to climate mitigation through marine ecosystem stewardship.
Target Audience
Primary customers are fashion brands, textile manufacturers, and yarn/spinner companies seeking high‑performance, sustainable fibers and fabrics derived from marine resources.
Features
- Marine biomass conversion technology that extracts usable polymers from algae, cyanobacteria, and shell waste
- Proprietary fiber blends (e.g., 70% Lyocell + 30% SeiFibre™) for yarns, fabrics, and coated canvases with comparable strength and drape to conventional textiles
- Integrated design validation: each material is produced as a finished garment for immediate brand testing
- Low material footprint: non‑water‑intensive, non‑land‑intensive, plastic‑free, and minimal reliance on finite resources
- Scalable production capacity of 510,000 lm per year, supporting pre‑ordered volumes from fashion partners
- Blue‑carbon contribution through sustainable harvesting of marine ecosystems
- Open collaboration model that shares processes, protocols, and knowledge with partner manufacturers
