Dutch Scientists Lead Million-Euro Project to Turn Food Waste into Protein
Wageningen, Friday, 25 September 2026.
A Wageningen University-led consortium has secured four million euros to convert potato and rapeseed agricultural waste streams into sustainable, high-value protein products for human consumption.
An Agritech Breakthrough in the Heart of Wageningen
This pioneering initiative falls squarely within the domains of agritech and food technology, representing a structural shift in how agricultural side streams are valued [1]. The VASCO (Valorising agricultural crop side streams into consumer foods) project is led by Wageningen University & Research (WUR), located in Wageningen, Netherlands [1]. Under the leadership of Personal Professor of Food Microbiology Heidy den Besten, the six-year project is backed by nearly €4 million in funding from the Dutch Research Council (NWO) [1]. Den Besten has assembled a robust consortium of 30 partners, including four prominent Dutch universities—WUR, TU Delft, Vrije Universiteit Amsterdam, and Universiteit Leiden—alongside vocational institutions, government bodies like the RIVM, and major corporate players such as Unilever and Royal Avebe [1].
How It Works: Dry Extraction and Microbial Fermentation
The technical framework of the VASCO project focuses on isolating high-value proteins from crop side streams that are typically downgraded to animal feed or biogas production [1]. The research targets legumes, rapeseed, and potatoes; rapeseed cake, for example, consists of approximately 30% protein [1]. To maintain an eco-friendly footprint, the team utilizes dry separation techniques for protein extraction, which Den Besten notes is significantly more sustainable than conventional wet extraction methods [1]. Following extraction, the team employs fermentation using specific bacteria and fungi to neutralize anti-nutritional compounds like glucosinolates and phytic acid, while simultaneously improving flavor, aroma, and synthesizing vital nutrients like vitamin B12 and vitamin K2 [1].
Environmental Benefits and Market Integration
The primary benefit of this innovation is its capacity to curb systemic food waste and support a circular economy [1]. According to Den Besten, roughly 20% of agricultural product is lost due to aesthetic issues like off-spec colors and shapes, or supply chain mismatches [1]. By transforming these wasted fractions into consumer-ready meat alternatives, spreads, snacks, and tempeh-like fermented goods, the consortium directly supports the Dutch government’s broader goal to reduce reliance on imported soy [1][4]. To guarantee commercial viability, the project integrates consumer research from day one, helping to bridge the gap between cautious retailers and hesitant manufacturers [1]. This consumer-centric focus comes at a crucial time, as recent market data indicates that while 52% of Dutch consumers consciously choose plant-based meat alternatives, only 29% do so for dairy [3]—a difference of 23 percentage points that highlights the varying adoption rates of plant-based proteins.
A Growing Ecosystem of Dutch Foodtech Innovation
The VASCO project is part of a broader wave of foodtech and agritech developments taking place across the Netherlands in late 2026 [5]. For instance, the Dutch Chamber of Commerce (KVK) recently announced its 2026 Innovation Top 100 finalists, highlighting several regional startups [5]. Among them is Leiden-based Rift Protein, which extracts highly soluble proteins from East African mung beans, and Dutch Structuring Technologies, operating out of Maastricht and Wageningen, which utilizes patented Sheartex Technology to create high-quality fiber structures for meat and fish analogs [5]. These collective efforts underscore how critical the collaboration between academic institutions and commercial enterprises remains for accelerating the global protein transition [5].
