About the I3-4-SEAWEED Project
The project champions interregional collaboration to scale, demonstrate, and bring to market new business ventures in the macroalgae and seaweed sector. By connecting innovative SMEs, universities, tech hubs, and industry clusters, the project is building a transnational value chain focused on sustainable seaweed cultivation and algal biotechnological applications.
From food and biofertilizers to cosmetics, seaweed holds the potential to transform industries and contribute to regional development, especially in coastal and maritime regions. With its capacity to promote healthier diets, support climate goals, and drive local economies, seaweed innovation represents a vital step toward a more sustainable future.
