Seaweed recycle nitrogen, phosphorus and carbon dioxide from the sea, provide habitats for other organisms and is a source to vegetative food and feed. NSA aims to valorize the contribution to the ecosystem.

Norwegian Seaweed Association (NSA) was established in March 2021 by merging two Norwegian seaweed networks. From 2010 different organisations have been working to mobilize a new marine industry based on marine algae. NSA has invited others stakeholders among R&D, suppliers and customers, investors and public funders to form a cluster to strengthen the seaweed industry development.
