Macroalgae are game-changing biomass resources for producing food, cosmetics and energy without competing for arable land, depleting fresh water and adding 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. The GRASS project conference will gather experts, from the Baltic Sea and beyond, with knowledge, initiatives, stories and practices. The aim to place seaweed in the heart of the Baltic Sea Region, to raise awareness, also among public authorities, on the arising benefits and opportunities of macroalgae and pave the way for future innovation and product development. For this the conference will give voice to the triple helix of innovation – industry, academia and government. During the conference, delegates will have the opportunity to elaborate on a developing position paper, a draft of which will be pre-circulated by the GRASS project partners.
