Edinburgh biotech MiAlgae secures £3.4m for sustainable feed production

Micro-algae-derived supplements producer MiAlgae Ltd has secured an estimated £3.4m Series A funding round to expand its output. The company, which was incorporated in 2016, manufactures additives for the farming and pet nutrition markets. Its process utilizes waste streams, including wastewater and by-products from whisky distillation, to cultivate the crop.

The biotechnology firm addresses the decline in wild fish stocks by offering a sustainable alternative to traditional fishmeal. By recycling nutritional co-products from the spirits industry, the circular solution returns clean water to the environment while producing essential polyunsaturated fatty acids and omega-3 nutrients. This approach aims to support the efficient rearing of livestock for a growing world population.

This latest capital injection follows a total of £7m raised in 2025 and brings the aggregate investment for 2026 to £2.5m. The business reported 59 employees in its most recent accounts for the year ended 30 September 2025. LinkedIn data indicates the current headcount has grown to 63 staff members. The round was finalized (allotment date in March) with formal documentation filed in June.
