Wageningen University Leads Four-Million-Euro Project to Upcycle Agricultural Waste into Food
Wageningen, Thursday, 10 September 2026.
With 20% of agricultural side streams currently wasted, a new six-year Dutch consortium is using advanced fermentation to transform these protein-rich residues into nutritious consumer foods.
An Agritech and Food Science Milestone
This pioneering initiative represents a major breakthrough in the fields of agritech and food science, specifically targeting the global protein transition [1][2]. At the helm of this six-year project is Wageningen University & Research (WUR), based in Wageningen, Netherlands [1][4]. Led by Heidy den Besten, Personal Professor at Food Microbiology at WUR, the “Valorising agricultural crop side streams into consumer foods” (VASCO) project has secured nearly €4 million in funding from the Dutch Research Council (NWO) [1][4]. The initiative is designed to establish an entirely new framework for upcycling agricultural side streams that are currently lost to low-value applications [1][2].
The Mechanics of Dry Fractionation and Fermentation
The core technical innovation of the VASCO project relies on two primary methodologies: dry fractionation and microbial fermentation [1][2]. Unlike conventional wet extraction, which requires substantial amounts of water and chemical solvents, dry fractionation is a highly sustainable, water-free process that isolates protein-rich fractions while fully preserving their functional properties for food applications [2][4]. To complement this, the researchers employ specific bacteria and fungi in a specialized fermentation process [1][2]. This microbial treatment serves a dual purpose: it effectively breaks down and removes undesirable anti-nutrients—such as glucosinolates and phytic acid—while simultaneously enriching the food with essential vitamins like B12 and K2, which are typically found in animal-derived products [1][2][3].
Targeting Crop Residues and Enhancing Nutrition
The scientific team is focusing its efforts on three major agricultural side streams: legumes, rapeseed, and potatoes [1][4]. Currently, these streams suffer from severe inefficiencies; for instance, approximately 20% of legume and rapeseed processing streams are discarded due to minor cosmetic defects or logistical supply chain issues [2][4]. Rapeseed cake alone contains up to 30% protein, yet this valuable resource is traditionally diverted to animal feed or biogas production [2][4]. By applying these advanced extraction and fermentation technologies, the VASCO consortium aims to transform these underutilized raw materials into high-value, edible consumer products, including meat alternatives, spreads, snacks, and tempeh-like fermented foods [1][2].
Climate Mitigations and Systemic Change
Upcycling these proteins yields profound environmental and economic benefits. Globally, food loss and waste are responsible for an estimated 8% to 10% of greenhouse gas emissions, making the valorization of agricultural side streams a critical climate necessity [2]. By keeping these proteins within the human food chain, the project directly supports healthier, more sustainable plant-based diets as advocated by the Dutch Health Council [2]. However, achieving systemic change requires more than just laboratory breakthroughs. As Professor Den Besten notes, a primary barrier is supply chain hesitation: “Companies are often only willing to invest once there is sufficient demand, while supermarkets will only stock products when they know there is a reliable supply” [4].
A Broad Consortium Driving Market Integration
To bridge this gap and accelerate market adoption, the VASCO project has assembled a diverse consortium of 26 partners [1][4]. This network includes four Dutch universities—WUR, TU Delft, Vrije Universiteit Amsterdam, and Universiteit Leiden—alongside applied sciences institutions, vocational schools, and nine commercial enterprises, including major industry players like Unilever and Royal Avebe, and agritech startups such as The Protein Brewery [1][2][4]. Together, they are working to identify supply chain bottlenecks, test prototypes directly with consumers, and build viable business models [2]. By training seven PhD candidates and one postdoctoral researcher, the project ensures that these cutting-edge agritech methodologies are deeply embedded into the future of academic and vocational food technology education [1][2].
