tleneck Problems encountered the high costs associated with cultivation of seaweed in Europe. cal and environmental Supplying macroalgae from open-sea “farms” is reliant on mechanised processes under harsh conditions. Only local species could be used. Adding nutrients is difficult within ecological constraints. The need for oxygen removal in closed (photo bioreactor) systems and CO2 injection in the process water to stimulate the growth rate; The harvest of the very small organisms; The breakdown of the algae cell to free the produced oil/lipids and conversion of the lipids to diesel or bio kerosene that could safely be used in the market. High cost of cultivation and availability of sites for pilots or mass production. s Public perceptions of the risks associated with biotechnology in the sector There is a low level of recognition of the contribution that marine biotechnology can make to the performance of the sector within policies at the EU level. Needs to be better embedded in CFP, MSFD, WFD and other policies and that the role of MB is Manufacture Manufacture Stage in value chain Manufacture Marketing & Selling Discovery & Research ment work on Blue Biotechnology
