Ensuring the safety and quality of our food sources through advanced fermentation techniques
Precision fermentation, a rapidly growing technology, is revolutionising the food industry by producing specific proteins and ingredients using microbes in controlled environments. This approach offers functional and sensory parity while significantly reducing environmental impact.
Companies like Perfect Day, Formo, Remilk, The EVERY Company, and Imagindairy are achieving commercial-scale production and forming partnerships with major industry players such as Nestlé, Mars, and Danone. This progress reflects strong market confidence and indicates precision fermentation is moving beyond proof-of-concept towards scalable food industry integration.
Environmental Advantages
From a sustainability and food security perspective, precision fermentation offers major advantages. It reduces reliance on land and water resources by 74–99% and 77–91%, respectively, compared to conventional agriculture. It also lowers greenhouse gas emissions by 37–87% relative to traditional protein production. Furthermore, it enables on-demand production in controlled environments, increasing supply chain resilience.
Economic Outlook and Challenges
The global precision fermentation market was valued at approximately $3 billion in 2024 and is projected to grow dramatically—reaching over $54 billion by 2032, with a compound annual growth rate (CAGR) of 43.5%. However, the industry faces substantial challenges, including the need for significant investments ($500 billion by 2040) for capacity expansion, regulatory navigation, talent acquisition, consumer acceptance, and cost reduction to achieve price parity with conventional proteins.
Creating a Circular, Low-Waste Bioeconomy
In terms of creating a circular, low-waste bioeconomy, precision fermentation can enable tailored production of ingredients that minimise feedstock waste, use of renewable feedstocks (e.g., agricultural by-products) as fermentation inputs, reduced emissions and resource consumption tied to food production, and potential integration with biorefinery and waste valorization systems, strengthening circularity.
The UK's Deep Branch and Beyond
Deep Branch, a UK-based company, is using microbes to convert carbon dioxide into sustainable protein for animal feed. This approach is slightly different as the microbes are an ingredient in the final product. Other companies like Protera are developing protein ingredients that can improve the shelf life of baked goods like bread.
The food security crisis highlights humanity's dependence on plant crops and animal farming for food production. Precision fermentation could provide a resilient, scalable protein supply with low waste. The Israeli firm ImaginDairy recently raised $28 million to fund the development of dairy proteins produced via precision fermentation. Solar Foods is developing a way to convert carbon dioxide from the air into sustainable protein using just a vat of bacteria and electricity.
In conclusion, precision fermentation is at an advanced stage with real-world commercial applications that are reducing environmental impact and enhancing food system resilience. Its future potential to address food security depends on overcoming scale, cost, regulatory, and acceptance challenges, but it stands as a key enabling technology for a circular, low-waste bioeconomy and sustainable global protein supply.
