Although circular economy seems like a new idea, Duynie Group have been working with co-products for more than 50 years now. At the moment we are European market leader in processing co-products released in food, beverages and bio-fuel industries. Duynie B.V. started in 1968 as a partnership between Arie Verduyn and Jan van Nierop. With a single truck they started delivering co-products to local farmers. This business soon expanded to a reliable supplier of co-products in the Netherlands. For over 50 years we have been driven to generate more value out of co-products.
