How can we make better use of plant-based by-products? That is the central question driving the international PROCAS project, in which Colubris plays an active role. The project explores how cassava, a widely cultivated tropical root, can be transformed into valuable products such as protein powder, fibers, syrup, and even clean water.
Marijn Zwijsen, Process Engineer at Colubris, is closely involved in the project. “The first tests took place at our facilities in Winterswijk, the Netherlands, using sweet cassava from Costa Rica. We then carried out practical trials in Vietnam with local, bitter cassava. These experiments have already provided valuable insights. For instance, we found that it is technically possible to extract proteins. However, the process does require smart steps in pre-treatment, separation, and cooling.”
