ARC CBBC: the Advanced Research Center Chemical Building Blocks Consortium. This is the Netherlands’ national research center for circular and sustainable chemistry. The hub exists of Utrecht University, the University of Groningen and the Technical University of Eindhoven, in collaboration with the chemical industry, represented by Shell, BASF and AkzoNobel. Together with members from universities all across the Netherlands, they collaborate on project level in multilateral and bilateral projects. ARC CBBC brings together representatives from industry, academia and the government to greenify the chemical industry. They mainly focus on our three research themes: energy transition, feedstock transition and materials transition. This collabarotion is an added value to connect knowledge clusters and hubs working together to create sustainable solutions for our society.
