CAPTURE is a strategic collaboration between excellent researchers from UGent, University of Antwerp, VUB and VITO on the use of secondary raw materials (by-products, by-products and waste streams). Water and CO2 are two important areas at CAPTURE, and the technologists are developing processes for the production of microbial protein using raw materials recovered or derived from wastewater and CO2. Collaboration and value chain thinking are key principles of CAPTURE to achieve integrated solutions for the circular economy.;
