Seaweed as a Sustainable Feedstock of the Future
(Algae Industry Magazine) Studies conducted by EnAlgae partners in Ireland, France and Belgium point the way to seaweed being a viable and sustainable feedstock for the future in North West Europe (NWE). This is the conclusion of a new paper entitled “Comparative environmental life cycle assessment of two seaweed cultivation systems in NWE with a focus on quantifying sea surface occupation” published by Sue Ellen Taelman et al.
For the study, the cultivation of Saccharina latissima was studied on both the west coast of Ireland at National University of Ireland in Galway, and in Northern France at CEVA – the Centre D’Etude et de Valorisation des Algues in Brittany.
The study found that the resource footprint of seaweed production in NWE is lower when compared to the footprint of microalgae (Nannochloropsis sp.) and similar to the ones of terrestrial plants such as sugar beets, maize and potatoes.
“There is great potential to reduce the resource footprint of seaweed cultivation when this technology is implemented on a larger scale and becomes more efficient by using less transport and electricity. Furthermore, the biomass productivity can still increase significantly (especially in France),” concludes the report.
