Biochains Atlantic project

The Breton seaweed industry is a real driver of the blue economy and innovation. With the European BIOCHAINS Atlantic project (2025-2028), led in Bretagne by Biotech Santé Bretagne, local players will benefit from unique support to promote their resources, strengthen their competitiveness and develop new collaborations across the Atlantic. From mapping stakeholders to value chain models, including a smart digital tool and networking events, this project offers Breton companies all the levers they need to innovate and expand into the European food and cosmetics markets.

The BIOCHAINS Atlantic project will bring very tangible benefits to stakeholders in the seaweed industry in Bretagne >>

🗺️ Mapping of stakeholders in the Atlantic region

A comprehensive interactive map of stakeholders in the Atlantic seaweed value chain (Spain, Portugal, France and Ireland) will be created. For Breton stakeholders, this will not simply be a database: the map will highlight their expertise, capabilities and innovations within the European seaweed ecosystem. It will also be a practical tool for connecting with partners and identifying new opportunities.

🤝 Themed days and networking events

As part of the project, Biotech Santé Bretagne will organise themed days and networking events, bringing together stakeholders from across the algae biomass value chain (with a particular focus on food and cosmetics). These meetings will enable Breton stakeholders to gain visibility, create opportunities for collaboration and identify synergies with other stakeholders.

🔗 Value chain models and knowledge capitalisation

The project will drive the development of algal biomass value chain models, providing roadmaps to help stakeholders navigate each stage, from bioresources to end products in markets such as food and cosmetics. BIOCHAINS will also centralise and harmonise knowledge that is currently scattered across numerous European projects.

These models will incorporate:

Thanks to BIOCHAINS, stakeholders in Bretagne will have a single point of access to the latest information: stakeholders, tools, knowledge, technologies and regulatory requirements.

💬 Personalised support

The project will not be limited to generic resources: partners will adapt models to offer personalised support to stakeholders throughout the project, until its completion.

💻 Digital tool

To ensure continuity beyond the duration of the project, BIOCHAINS is developing an intelligent digital decision-making tool. Based on value chain models and the information collected, it will generate personalised roadmaps for stakeholders and will remain freely accessible on the project website and those of its partners.

📝 Other deliverables

Breton stakeholders will also benefit from:

In summary, the project will enable Breton stakeholders not only to improve their internal competitiveness, but also to find the right international partners in the Atlantic and access the latest knowledge, tools and regulations. This combination of visibility, collaboration and access to innovation will directly support the development of the seaweed industry in Brittany.

The project is led in the region by Biotech Santé Bretagne, alongside three associate partners: Cluster Algues Bretagne, the Chambre Syndicale des Algues et des Végétaux Marins and Algolesko.

The project brings together seven partners in Europe:
