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 for strengthening the seaweed industry development.
