Macroalgae production is an upcoming sector for growing biomass for producing food, consumables such as plastics and energy without competing for arable land, depleting fresh water and using non-renewable fertiliser. However, the sector is still in its infancy in the Baltic Sea Region and there is a lack of in-depth and wide-spread knowledge on the potential benefits of macroalgae production. To deal with this challenge, GRASS aims to raise awareness and build capacity on macroalgae cultivation, harvesting and use among public authorities and other relevant stakeholders across the region. Public authorities, ministries, planning regions and counties play a crucial role in promoting macroalgae as they are the main legislative bodies that also control much of national and regional funding.
