Macroalgae: a potential still underexploited in Europe
Global seaweed consumption is booming, but Europe is lagging behind. Yet these superfoods could provide sustainable proteins with a low environmental footprint. The European market still needs structuring, with real opportunities for players ready to innovate.
While the global macroalgae market is growing rapidly, Europe still lags far behind Asia, where these seaweeds are an integral part of everyday diets. An article published in January 2026 in the Journal of Agriculture and Food Research analyzes the potential of macroalgae in Europe as an alternative source of protein, capable of meeting rapidly expanding global demand.
The study identifies both strengths and constraints for the development of this sector. Among the advantages: cultivation that requires little land and freshwater. Among the obstacles: high production costs and a European value chain that is still poorly structured.
To support the growth of this market, the authors set out six key recommendations:
- Harmonize regulations at the European level to facilitate trade and market access.
- Inform and raise consumer awareness to reduce barriers linked to the acceptance of new food sources.
- Strengthen research and innovation to improve production techniques and the added value of products.
- Optimize the supply chain to reduce costs and secure flows.
- Set up collaborative platforms bringing together authorities, industry and researchers.
- Encourage sustainable practices aligned with the European blue economy strategy, for an ocean-friendly value chain.

Developing the Seaweed and Shellfish Sectors: Key Recommendations
To promote the sustainable expansion of the seaweed and shellfish sectors in Europe, a report proposes a series of strategic measures aimed at securing projects, optimizing maritime space, and strengthening the sector’s competitiveness.
The report recommends simplifying and harmonizing regulatory frameworks, particularly through the creation of national one-stop shops, clarification of administrative responsibilities, and reduction of authorization timeframes. These measures aim to secure and accelerate the development of farming projects.
It also emphasizes the importance of better integrating shellfish and seaweed farming into maritime spatial planning. This approach helps limit conflicts with other uses—renewable energy, transport, fishing, or tourism—and ensures stable access to the most suitable areas.
Financial support represents another major lever. The report advocates for increased mobilization of European funds, the implementation of risk-sharing mechanisms, and specific support for small and medium-sized enterprises, in order to stimulate investment and innovation.
Finally, the document stresses the need to invest in research, training, and advanced technologies, such as genetic selection, automation, and integrated multi-trophic aquaculture (IMTA) systems. It also recommends structuring and energizing value chains by developing processing, standardization of seaweed-based products, consumer awareness, and the creation of high-value outlets, to ensure the sector’s competitiveness and sustainability in the long term.
