Sweaweed – Seaweed production systems with high-value applications

Research project
Active research
Project period
2015 - 2020
Project owner
Department of Marine Sciences

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.
