Estonian biotech startup Äio has recently raised €6.1 million in venture capital funding to build a state-of-the-art demonstration plant in Estonia. This pioneering facility in the region will produce environmentally friendly oils and fats from wood and agricultural residues, positioning the company as a game-changer in the food industry. As a spin-off from Tallinn University of Technology (TalTech), Äio’s process offers a sustainable alternative to conventional oils, including palm oil and animal fats, that often contribute to deforestation, environmental degradation, and excessive resource consumption.
Founded in 2022 by TalTech bioengineers Petri-Jaan Lahtvee and Nemailla Bonturi, Äio’s innovation converts industrial by-products like sawdust and agricultural waste into food-grade fats and oils. Using a patented fermentation process involving specially designed “red yeast” microbes, the company transforms these raw materials into fats rich in healthy fatty acids and antioxidants. The process is comparable to brewing beer but focuses on sustainability and food technology.
This approach reduces dependence on palm oil and animal fats, which have been long criticized for their harmful environmental impacts. Nemailla Bonturi, co-founder of Äio, highlights the significance of this advancement:
“Our oils, produced from industrial residues, help reduce land use by up to 97% and water consumption by up to 10 times compared to current palm oil and animal fat production.”
The process is not only resource-efficient but also fast, with oil and fat production occurring up to 10 times quicker than traditional methods, further emphasizing its potential to revolutionize the food industry.
Fresh Funds to Fuel Growth
The recent €6.1 million investment, led by Voima Ventures, 2C Ventures, SmartCap, and Nordic Foodtech VC, is earmarked for the construction of a demonstration plant by 2026. The plant will be the next significant step in scaling Äio’s three primary product categories: encapsulated oil, red oil, and butterfats. These products aim to replace palm oil in various industries, including food, cosmetics, and household goods.
In addition to the food industry, Äio’s Red Oil has promising applications in cosmetics and household products, positioning the company to expand into multiple markets. With a commitment to sustainability, Äio ensures that its oils are versatile while reducing the environmental footprint associated with conventional fats and oils.
Pontus Stråhlman, a partner at Voima Ventures, emphasized the ecological benefits:
“Äio’s approach addresses the problem of the palm oil industry destroying diverse forests by turning agricultural and forestry by-products into high-quality substitutes, leading to significant reductions in CO2 emissions and land use.”
Big Wins and Global Support
Äio’s impact reaches far beyond Estonia. The startup has already secured over 120 global partnerships, collaborating with companies eager to leverage its innovative products. In addition, Äio has been selected for the prestigious European Joint Undertaking on Circular Bioeconomy project, which has a budget of €7.5 million. This initiative will further enhance the company’s capabilities in developing fat-based materials and cosmetic products in partnership with European collaborators.
With a growing team of 16 experts in bioprocessing, synthetic biology, and food technology, Äio is well-positioned to scale its production and continue innovating sustainable solutions for the global food industry.
Redefining the Future of Sustainable Food Production
Äio’s success reflects a broader shift towards sustainability and innovation within the food industry. Conventional oils, particularly palm oil and animal fats, have faced intense scrutiny due to their environmental impact, including deforestation, habitat destruction, and high water usage. By offering a sustainable alternative sourced from wood and agricultural residues, Äio addresses these critical issues head-on.
In 2023, Äio made waves by raising an initial €1 million in venture capital to develop its alternative product categories. This early success laid the foundation for the company’s rapid growth, culminating in the recent funding round, enabling the construction of a large-scale facility.
With production expected to begin by 2026, the demonstration plant will be a significant milestone for the company, allowing it to produce commercial quantities of encapsulated oil, red oil, and butterfats. While the exact location of the plant has yet to be finalized, it is expected to be situated near a large industrial company that can provide raw materials through partnerships with Estonian and Finnish food industry companies.
Rise of Fermentation-Led Alternatives to Fats and Oils
Globally, startups are turning to precision fermentation to address the environmental concerns associated with traditional fats like palm oil. NoPalm Ingredients, a Dutch company, has developed yeast-derived oils as a drop-in replacement for palm oil. Using a proprietary non-GMO fermentation process, NoPalm Ingredients transforms agri-food waste streams, such as potato peels and whey, into oils. Their process reduces CO2 emissions by 90% and land use by 99% compared to conventional palm oil production. Their ability to produce palm oil alternatives at price parity without requiring recipe reformulation has garnered partnerships with major companies like Unilever and Colgate-Palmolive.
Melt & Marble, a Swedish startup, uses precision fermentation to create designer fats tailored for meat alternatives. Their technology engineers yeast to produce fats with specific sensory properties, addressing the taste and texture challenges in plant-based foods. Similarly, Hoxton Farms in the UK is growing animal fat in a lab using stem cells, combining computational modeling with fermentation to develop an ethical and sustainable product that mimics the texture and taste of real animal fat.
In Spain, Cubiq Foods is leading the charge by utilizing a combination of fermentation technologies to create healthier fat alternatives for industrial food production. Their recent collaboration with Cargill aims to scale these innovations for mass production.
The fermentation-based fats and oils sector has seen a surge in investment. Between regulatory changes and growing consumer demand for sustainable products, the precision fermentation market is expected to expand rapidly. According to GFI, in Europe alone, precision fermentation startups raised over €164 million in the first half of 2024, surpassing previous records for the sector. These companies are at the forefront of developing alternatives that meet the environmental challenges posed by palm oil production and traditional animal fats.
Äio’s successful venture funding, along with the progress of other companies like NoPalm Ingredients and Melt & Marble, signals a transformative moment in the food industry. By focusing on upcycling waste materials and leveraging biotechnology, these companies are paving the way for sustainable, scalable solutions to conventional oils. With the continued support of investors and industry giants, the fermentation-driven alternative fats and oils sector is poised to grow exponentially, offering a glimpse into a future where environmentally destructive fats like palm oil may no longer dominate the market.
This wave of innovation, backed by both environmental necessity and significant venture capital, will be crucial in the global effort to reduce deforestation, CO2 emissions, and land use.
