The transformation of our linear economy into a circular economy poses a formidable challenge. This publication offers a concise overview of six potential ‘gateways to circularity’. ‘Gateways’, as each of them can provide a starting point or entrance for research and educational institutions and businesses alike to actively take part in the transformation to a circular economy by leveraging their particular expertise, be it design, engineering, material sciences, information technology, business theory or the arts. Each chapter is illustrated with a selection of cases of circular design research projects and pioneering business ventures in the Netherlands.
