The Bank has invested £2.5m into Scottish biotech company MiAlgae to support the company’s new commercial-scale production facility in Grangemouth.

MiAlgae produces an Omega-3 powder using by-products from the whisky distilling process. Its plant-based product provides an alternative source of Omega-3, which is traditionally derived from wild-caught fish. Omega-3 is a sought-after ingredient in the aquaculture feed and pet nutrition markets due to properties that promote healthy skin and coats, cognitive function and joint health.

MiAlgae’s Omega-3 powder is sustainable, fully traceable and supports Scotland’s circular economy while reducing reliance on wild-caught fish. The company’s pioneering approach gained international recognition in 2024 when it was shortlisted for The Earthshot Prize under the “Revive our Oceans” category, in recognition of its scale-up potential and ecological impact.

Founder and CEO Douglas Martin set up MiAlgae in 2016 while studying synthetic biology and biotechnology at the University of Edinburgh. The university has remained a backer of MiAlgae’s technological innovation.
