The overarching goal of this project is to develop a sustainable system
for the use of seaweeds as a renewable resource in a future, biobased
Swedish society. The transdisciplinary research approach includes
techniques for cultivating seaweeds to be used as raw material in a
biorefinery for the production of food, feed, biobased materials and
Seaweed farming circumvents several disadvantages related to land-based
biomass production, e.g. the need for fertilizers and irrigation, and
does not compete for valuable arable land. In addition, seaweeds grow
fast and their farming counteracts coastal eutrophication. A holistic
approach will be used where utilization of the resource is maximized in
each step of the cycle.
Seaweeds will be cultivated at the Swedish west coast and methods suitable for preservation and storage will be evaluated.
The obtained biomass will subsequently be fractionated in an integrated
biorefinery. The different fractions are thoroughly characterized and
recovered for production of biochemicals, polymers, and food/feed
additives. The residues from the biorefinery are utilized for production
of biogas and biofertilizers. In parallel, a general multi-process
sustainable assessment method will be developed to analyze the overall
sustainability of the system. The multi-disciplinary research team will
collaborate closely with a set of state agencies, commercial enterprises
and other stakeholders in the different tasks of the project.
