Biotech innovator MiAlgae is building a major sustainable algal omega-3 facility in Grangemouth, Scotland, to meet rising demand from the pet food and aquaculture markets.
MiAlgae has broken ground on a major new scale-up facility in Grangemouth, Scotland. The new site will dramatically increase the supply of high-quality, fish-free omega-3 oils for the global pet food industry, meeting rapidly rising demand for clean-label, sustainable, and functional ingredients.
AN EXCITING NEW CHAPTER FOR MIALGAE
Douglas Martin, Founder and CEO of MiAlgae, said: “Breaking ground at Grangemouth marks an exciting new chapter for MiAlgae. Our mission has always been to make a meaningful impact, tackling overfishing, reducing waste, and creating sustainable value from industrial by-products. This new facility is a huge step towards delivering that mission at scale, bringing new, high-quality green jobs to the local area, and helping Scotland lead the way in this exciting new biotech industry.”
The large-scale facility, going live in early Q2 2026, will increase MiAlgae’s pet nutrition omega-3 output more than tenfold, enabling manufacturers to incorporate premium DHA into dry, wet, and supplement formats without relying on wild-caught fish oil. The company states that the expansion will also:
• Save six billion fish annually by replacing marine-sourced omega-3s,
• Recycle 36.1 million litres of whisky by-products through MiAlgae’s circular process,
• Create hundreds of new green jobs in biotechnology, engineering, and production at full scale.
Backed by a joint investment of up to £3 million by the UK and Scottish governments, the new facility is designed with modular scalability, allowing MiAlgae to meet growing demand from pet food and aquaculture brands alike. Located close to both key raw material suppliers and major customers, the site will support a low-carbon supply chain for pet nutrition manufacturers across the UK, EU, and U.S.
SUSTAINABLE OMEGA-3 DERIVED FROM WHISKY BY-PRODUCTS
MiAlgae’s process upcycles Scotland’s whisky industry by-products to grow microalgae naturally rich in DHA, an essential fatty acid linked to improved skin and coat health, cognitive function, joint mobility, and immunity in pets. The result is a fully traceable, vegan, and low-carbon omega-3 ingredient that aligns with consumer demand for sustainability and transparency in pet nutrition.
