Sweaweed – Seaweed production systems with high-value applications
Short description
Marine seaweed is an unexplored resource in Swedish coastal waters. Besides as food ingredients, seaweed biomass is a potential source for fine chemicals, bio-based materials and other attractive applications. In this project we develop new methods for cultivating green and red seaweeds in Sweden, and sustainable techniques for extracting seaweed-based high value compounds.
