Seaweed has shown promise as a blue carbon sink, alternative protein source, livestock feed supplement, biofuel, and more. However, to realize this potential a cost-effective and scalable method for cultivating high-value seaweed products is needed. This project will develop a Recirculating Aquaculture System for the controlled cultivation of seaweed, conduct pilot studies to explore potential uses of the product, and partner with other OSU faculty to assess the economic and environmental feasibility of expanding this approach regionally and globally. Moreover, we will examine the socio-economic implications of establishing large-scale seaweed farms within and beyond the US.
