Global demand for seaweed is high and will continue to grow in the coming years. This offers a unique opportunity for sustainable growth of the aquaculture sector in the North Sea region. In recent years, several small-scale seaweed initiatives have been launched in the European coastal region, especially close to the coastline. However, large-scale cultivation of seaweed is not yet possible with the current state of cultivation techniques. In the Seaweed & Wind project, companies (Seaweed Harvest Nordsea, AtSeaNova, Murre Technologies, GEOxyz and Stichting Noordzeeboerderij) and knowledge institutions (HZ University of Applied Sciences and UGent) want to significantly increase seaweed production.
