MiAlgae, a Scottish startup innovating in the biotechnology sector, is transforming the way omega-3 fatty acids are produced. With a recent £14 million ($18.5 million) Series A funding round, the company is set to scale its operations and significantly impact the global omega-3 market. The round, supported by investors such as SWEN Blue Ocean, Clay Capital, Rabo Ventures, and several others, brings MiAlgae’s total equity funding to £20 million ($26.6 million). This capital injection will fuel the development of a new commercial-scale facility in Scotland, poised to produce thousands of tons of omega-3-rich microalgae annually. This article delves into MiAlgae's innovative approach, the market potential for omega-3s, and the broader implications for sustainability and the circular economy.
A New Frontier in Omega-3 Production
Omega-3 fatty acids, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are essential nutrients traditionally sourced from fish oil. However, with declining fish stocks and rising prices, the need for sustainable alternatives has never been greater. MiAlgae addresses this challenge by cultivating microalgae in fermentation tanks using heterotrophic algae from the Thraustochytrids class. Unlike photosynthetic algae, these microorganisms grow in the dark, deriving carbon and energy from organic compounds like sugars or other dissolved organic matter.
MiAlgae's unique feedstock is derived from byproducts of Scottish whisky distilleries, which provide a nutrient-rich base for the algae. Founder and CEO Douglas Martin explains, “In the distillery, they basically take the alcohol and we take the remaining liquid—which contains some carbohydrates, nitrogen, phosphorus, trace elements, and trace metals—and use it as our base feedstock.” This innovative approach not only minimizes waste but also integrates seamlessly into the circular economy model by converting a potential waste product into a valuable resource.
Scaling Up: The New Commercial Facility
MiAlgae currently operates a demo-scale facility in Balfron, Scotland, producing a few tons of omega-3-rich microalgae each week. With the new funding, the company plans to develop an industrial-scale facility between Edinburgh and Glasgow, expected to come online by mid-next year. “We’re looking at somewhere between Q1 and Q2 next year that we’ll start to see production coming out,” says Martin. This modular system allows for incremental scaling, enabling the company to ramp up production as needed without massive upfront capital expenditure.
MiAlgae's primary focus is the aquafeed market, particularly farmed salmon, which has seen significant growth in recent decades. As the global fish oil supply stagnates around one million tons per year, alternative sources of omega-3s are critical to meet the industry's demands. MiAlgae aims to provide a consistent, sustainable, and local alternative to fish oil, reducing the industry's reliance on wild-caught fish. The biomass produced by MiAlgae’s fermenters can be sold as a liquid concentrate or a powder, ideal for aquaculture and pet food applications.
A Sustainable Solution for a Growing Market
The global aquaculture industry has expanded more than fivefold over the past 30 years, yet the supply of fish oil, the primary source of omega-3s for farmed fish, has not kept pace. This mismatch has led to unsustainable fishing practices and environmental degradation. MiAlgae’s innovative approach, which utilizes whisky distillery byproducts, offers a scalable and sustainable solution to these issues. By extracting 95% of the nutrients from the distillery byproducts, MiAlgae not only produces valuable omega-3s but also contributes to water purification.
Investors are recognizing the potential of MiAlgae’s technology to disrupt the omega-3 market and address critical environmental challenges. “The Blue Ocean Fund targets startups tackling threats to our oceans such as overfishing, pollution, and climate change,” says Christian Lim, managing director of SWEN Capital Partners. “MiAlgae’s innovative microalgae fermentation addresses the omega-3 supply gap with a scalable, sustainable alternative to fish oil.” This confidence is reflected in the diverse array of backers in the Series A round, including social impact investors and venture capital firms.
The Road Ahead: Full Commercialization and Market Expansion
MiAlgae’s new facility will enable the full commercialization of its flagship product, NaturAlgae, a rich source of omega-3s. The modular system will allow the company to adjust production capacity based on market demand, ensuring a flexible and scalable growth strategy. By targeting the domestic aquafeed market initially, MiAlgae can establish a strong foothold before potentially expanding into the human food and supplements market, which would require additional processing and purification steps.
As the world grapples with the twin challenges of overfishing and climate change, MiAlgae’s approach offers a beacon of hope. By providing a sustainable and scalable source of omega-3s, the company is not only meeting a critical market need but also contributing to the health of marine ecosystems. With the new commercial-scale facility set to become operational next year, MiAlgae is well-positioned to lead the charge in sustainable omega-3 production.
MiAlgae’s pioneering work in microalgae cultivation represents a significant breakthrough in the production of omega-3 fatty acids. By leveraging byproducts from the whisky industry and focusing on sustainable, scalable production methods, the company is poised to make a lasting impact on the aquaculture industry and beyond. As MiAlgae moves toward full commercialization, it stands as a testament to the power of innovation and the promise of the circular economy in solving some of the world’s most pressing challenges.
