The PROTEUS Project—short for “kelP side stReam valOrisaTion to dEvelop new biobased valUe chainS”—recently hosted a roundtable in Brittany, France, to explore the future of algae-based industries. The event, led by NORSUS (Norwegian Institute for Sustainability Research), gathered local stakeholders including researchers, businesses, and industry representatives.
Purpose of the Event
The goal was to discuss the environmental, social, and economic challenges of using algae sustainably and effectively. The event was held at the Breizh Algae School, near the Olmix production site.
Before the discussion, Ilka Czech from Alginor presented a new sustainable biorefinery concept, which sparked strong interest and many questions from attendees.

Key Findings from the Roundtable
Environmental Insights
- Main concerns: How to harvest algae sustainably, measure environmental impact, and manage recycling and heavy metals.
- Key takeaway: There’s a strong need for shared standards and methods for algae harvesting and environmental monitoring.
Social Considerations
- Topics discussed: Balancing cultural traditions with industrialization, defining what’s truly “green,” and adapting practices to local contexts.
- Key takeaway: We need better communication about sustainability and flexible, localized approaches to algae use.
Economic Challenges
- Issues raised: Over-reliance on alginate, unfair global competition, and the need for EU-wide import regulations.
- Key takeaway: To stay competitive, the industry must diversify products, increase the value of co-products, and push for fair trade policies.
Other Notable Points
- Alginor’s edge: Competitive pricing, pharmaceutical certification, and full use of algae biomass (not just alginates).
- Consumer awareness: Many don’t know that algae is often processed with formaldehyde—raising questions about transparency and safety.
- Sustainability: Proper harvesting can actually help algae grow better, contrary to public perception.
Algae in Brittany: A Rich History
Algae have been used since prehistoric times—for food, medicine, and even mattress stuffing. Today, companies like Olmix are pioneering new algae-based solutions for agriculture, health, and more.

About the PROTEUS CBE JU Project
Funded by the Circular Biobased Europe Joint Undertaking (CBE JU), the PROTEUS project—led by Alginor—aims to develop cutting-edge biorefinery technology to make better use of kelp side streams in a sustainable way.
This Proteus flagship project is financed by Circular Biobased Consortium Joint Undertaking (CBE JU). The coordinator Alginor is building state-of-the art technology and biorefinery to sustainably utilize new Kelp side streams from Kelp biomass.
