Roadmap naar een duurzame zeewierteelt
 Kennis ontwikkeling voor waardecreatie
● Inland, lab schaal, mesocosms,
● Inshore (Oosterschelde, Waddenzee,...)
● Nearshore (vooroever, Haringvlietmond,...)
● Offshore (NZB, Windmolenparken)
 Ontwikkeling van de gehele keten (van veredeling tot
consument).
 Mét het bedrijfsleven (Olmix, Cargill, SeaMore, )
Dank voor de
aandacht.
Ulva Lactuca (green) in TO2
Carbohydrate extraction (ECN)
What is most optimal extraction
method?
Ulva
Carbohydrates
(Non)food applications and
biofuels
Residues (LR)
- How to reduce mineral content?
- In vitro/ in vivo experiments (material, budget)
Feed (LR)
- High value feed ingredient (proteins)
- Potential competitive feed ingredient
Protein extraction (FBR)
How to deal with hindrance of
carbohydrates?
Proteins
Technical application (FBR)
Production of PUR-like foam:
proof of concept
Food
Production of cheese
Additional research questions:
ECN: What is the variation in composition (carbohydrates/proteins) in time?
LR: What bioactive (e.g. immuunmodulating) components can be obtained?

Laminaria, Saccharina (brown) in TO2
Laminaria
Saccharina
Food
Mannitol
Conversion to
isomannide (ECN)
Conversion to
mannitol derivative
(FBR)
Production of
polycarbonate (FBR)
Replacement of
Bisphenol-A
Mannitol extraction (ECN)
Residues (LR)
- How to reduce mineral content?
- In vitro/ in vivo experiments (material, budget)
Technical application
Chemical building block for bioplastics
Technical application
Bioplastic
Feed (LR)
- High value feed ingredient (proteins)
- Potential competitive feed ingredient
Additional research question:
ECN & FBR: Additional valorization of carbohydrates such as alginate
(hydrocolloid) and laminarin to biofuels, chemical building blocks
LR: What bioactive (e.g. immuunmodulating) components can be obtained?
