Global seaweed business
2014: > 25 Mio tons (ww) which corresponds to 7-8 Bio USD o Majority is being cultivated o Mainly reds and browns 75% used for food (nori, wakame, kombu, etc.) 13% for hydrocolloids (alginates, carrageenan, agar) 12% other applications (personal care, cosmetics, fertilizer, etc.)

Our objective
If we want to develop a profitable and sustainable seaweed business in Europe we have to: Mechanize all processes (seeding, monitoring, harvesting, etc.) => cost-efficient Cultivate 2D (or 3D) Cultivate in a smart and sustainable way => integrated Serve existing and new markets

Our concept
Development of substrates based on advanced textiles to facilitate open sea cultivation of aquatic biomass (seaweed), having a high-potential as source for our future supply of food (additives), feed, biochemicals/biomaterials and biofuels/energy
Advanced textiles for open sea biomass cultivation (AT~SEA)

Conclusions o Seaweed cultivation in Europe has huge potential for multiple applications (IMTA, food and feed (additives), bioremediation, biochemicals/materials, etc.) o The AT~SEA consortium has developed, patented (PCT) and demonstrated advanced 2D textile substrates* that yield 3-5 times more biomass than state of the art 1D rope based systems o Success of AT~SEA lies in the multidisciplinary of the project and the product
project: chemists, materials scientists, textile engineers, biologists, marine engineers, etc. product: much more than just a piece of textile => system
* Award winning technology: o Essenscia Innovation Award 2013 o TechTextil Innovation Award 2015 o Nomination for Scottish Aquaculture Award 2015 (final selection in June)
