In line with the concept of the EU Agenda for Sustainable Blue Growth in the Baltic Sea Region, the ALLIANCE project promotes collaboration among blue biotechnology stakeholders. Blue biotechnology is a sector with great potential as Europe moves towards a bio-based economy. It can be tapped for products such as new medicines, biofuels, food, and nutritional supplements. It will also play a key role in developing ecosystem services related to clean water. This potential is impressive, but – to date – largely untapped, with realization still in its infancy.
