Producers of Cichorium crops produce significant quantities of by-products and waste fractions that have so far yielded little. However, they contain valuable components. Semi-finished products from the biorefinery of Belgian Endive roots can serve as an ingredient for food and drinks or as a raw material for the production of bioplastics. Within the CichOpt project, researchers are investigating how these waste fractions and by-products can provide real added value for the Belgian Endive grower in the future.
