Food waste fermentation technology developed by Copenhagen-based Reduced converts processing byproducts into premium savory flavors through a three-day process using 10 times less energy than conventional methods.
Food waste fermentation technology receives major backing as Danish biotech company Reduced closes a €4 million Series A extension. The investment brings the total Series A financing to €12 million. The company transforms underutilized food processing side streams into clean-label savoury ingredients for large-scale manufacturers.
Delphinus Venture Capital co-led the round alongside existing investors Novo Holdings, ECBF VC, and EIFO. The funding will support the industrial scale-up of Reduced’s platform, expanding production capacity, strengthening quality systems, and deepening commercial partnerships across Europe.
Reduced combines solid-state fermentation with controlled reaction processes. The approach converts food industry byproducts into high-value ingredients at an industrial scale. Founders Emil Munck de Voss and William Anton Lauf Olsen established the company in 2016. Their food waste fermentation technology leverages rice koji fermentation to produce flavors in just three days.
The process uses 10 times less energy than current methods. It generates up to 83% lower greenhouse gas emissions compared to conventional flavor production. The company’s Waste to Taste technology produces complex flavor profiles, including umami, kokumi, and Maillard reaction notes.
Current product offerings include mushroom, vegetable, shore crab, and chicken concentrates. These ingredients deliver roasted character, depth, and sensory complexity comparable to traditional flavour systems. Unlike conventional alternatives, the platform produces additive-free flavour compounds naturally derived from side streams.
Food manufacturers face mounting pressure to reformulate products with clean-label ingredients while maintaining taste, functionality, and cost efficiency. The global savory ingredients market represents a multi-billion-euro opportunity. Existing solutions often rely on hydrolyzed vegetable proteins or meat and yeast extracts that lack the required complexity.
The food waste fermentation technology addresses these challenges directly. By valorizing side streams from food processing, Reduced contributes to a more circular food system. Food waste accounts for up to 10% of global emissions and causes $1 trillion in annual economic losses. Reduced has already saved over 150 tons of food through its operations.
The company recently announced a partnership with Royal Greenland, one of the world’s largest seafood suppliers. The collaboration transforms prawn processing side streams into clean-label taste solutions. Prawn shells and heads account for nearly half of coldwater prawn biomass and are traditionally used as low-cost feed ingredients.
Food waste fermentation technology upcycles this material into natural prawn concentrate with exceptional flavor and broad application potential. Royal Greenland holds Marine Stewardship Council certification for its sustainable coldwater prawn fisheries. The supplier brings scale, supply chain credibility, and clear market routes to the partnership.
The expected prawn product will offer an exceptional flavor profile with distinct umami and roasted crustacean notes. The ingredient provides clean-label credentials free from yeast extracts, additives, or flavorings. Culinary versatility allows it to be used in soups, sauces, condiments, snacks, and ready meals. The product features shelf stability with a lifespan of up to two years.
The global prawn market was valued at $56.33 billion in 2022 and is projected to grow at 5.4% annually through 2030. Marine flavor enhancers derived from shrimp shells account for about 6% of the global flavor enhancer market, growing at a 6.3% annual rate. Fish soups and sauces account for around 75% of the total market for marine extracts.
Consumer trends show that fish and seafood launches with clean-label claims continue to grow, especially in Europe. Claims include no additives or preservatives, natural designation, and organic certification. This market demand drives interest in food waste fermentation technology solutions.
Over the past year, Reduced doubled its industrial partnerships and expanded its product portfolio across multiple application categories. The growth underlines increasing market traction for the platform. The Series A extension marks a decisive step in the company’s transition from technology development to full industrial supply.
Emil Munck de Voss explains that 2026 will focus on continuing the industrialisation of core technology. The investment enables acceleration of that journey. Strong momentum exists with industry and food service partners across Europe. Being well-capitalized, with strong backing from new and existing investors, represents an important step.
Mathias Brink Lorenz, Managing Partner at Delphinus Venture Capital, expressed pleasure in joining the investor group. Reduced has the rare combination of a strong commercial founding team coupled with a solid technical platform to scale from.
Thomas Grotkjær, Partner at Novo Holdings Planetary Health Investments, noted that Reduced built a compelling enzyme and fermentation-based platform for producing high-value natural savoury ingredients. The financing helps strengthen quality systems, scale production, and accelerate progress with key industrial partners.
Jowita Sewerska, Investment Director at ECBF, stated that industrial food ingredient production must become both more sustainable and more resilient. The food waste fermentation technology demonstrates how circular bio-based technologies deliver competitive solutions for global manufacturers.
The investment strengthens Reduced’s position among fermentation startups and is transforming the flavor industry. France’s Fungu’it raised $4.6 million last year to upcycle agricultural byproducts into natural flavors through fungal fermentation. Another Danish firm, Summ Ingredients, secured $2 million to bring fermented protein to market.
The success of food waste fermentation technology at Reduced demonstrates how innovation can address multiple challenges simultaneously. As the company scales production and expands partnerships, it offers a blueprint for transforming food industry waste streams into valuable resources. The approach proves that sustainability and commercial viability can align when technology solves real problems for manufacturers and consumers alike.
