Seaweed do also need minerals such as nitrogen (N) and phosphorous (P) to grow but also absorb other minerals. Seaweed as such has the capability to accumulate minerals in its cell structure. The GOA-ventures technology offers a great opportunity to retrieve these minerals from the environment and from the bio-refinery process. Both free as well as bound minerals could be retrieved during the process. The collection of these minerals offers a great additional extracted product value.
