This initiative is a cooperation between the Center for Sustainable Chemistry and the Center for Sustainable Development. An interdisciplinary team will look upon sustainable chemistry and circular economy from a new perspective and will develop a new vision by taking into account societal and governance aspects. This initiative aims at the initiation of a change in technological research via the implementation of socio-technical problems in the design phase. Focus will be on process intensificationapplied on the valorization of urban waste streams and photochemical processes, two research domains which are still in their infancy.
