What Duynie Feed does
Duynie Feed (legal name: Duynie Ingredients B.V.) is a Dutch circular-economy company that processes agricultural co-products into feed, food, pet food, technical, and renewable applications. Founded in 1968 and headquartered in Katwijk (NB), Netherlands, the company operates as a subsidiary of Royal Cosun, a Dutch agricultural cooperative that acquired it in 2002. The business processes approximately 6.5 million tonnes of co-products annually sourced from breweries, food manufacturers, and other agricultural producers, operating across 21 European countries with roughly 500 employees.
The company's core operations involve collecting, processing, and valorising side streams such as spent grain from breweries (notably through a strategic partnership with Heineken), co-products from starch and sugar processing, and other agricultural residues. It operates through five segments — Food, Feed, Petfood, Technical, and Renewables — and invests in proprietary separation and valorisation techniques, including spent grain separation technology co-developed with Heineken under the LIFE Project FWFB. R&D initiatives such as RevOLEOtion (sunflower oleosomes) and Circular Qrunch extend the platform into higher-value food and bio-based applications.
Revenue is generated through B2B sales of processed feed ingredients, food applications, pet food components, technical materials, and renewable energy inputs to industrial customers across the European food and feed value chain. The customer base includes large enterprise accounts (e.g., Heineken, Crown Van Gelder, Fiorini) alongside a broader network of feed, food, and renewable buyers across multiple segments. As a subsidiary of Cosun, Duynie benefits from cooperative-level supply relationships and shared back-office infrastructure, supporting its cost position across European markets.
