This network brings together an exceptionally strong team of world-leading experts from a wide set of beneficiaries and partners in order to achieve breakthroughs in understanding how the transition towards a Circular Economy (CE) can be realised in a successful way in the European context, both within existing organisations and industries as well as through innovative and sustainable business models. The proposed approach is inherently multi-disciplinary, drawing upon research that will advance significantly the state-of-the-art in terms of the current understanding of the applicability of the CE paradigm from Economic, Environmental and Social points of view, providing policy insights and implications for practice. The consortium of 10 beneficiaries (including 7 academic and 3 non-academic groups) will design and deliver world class multidisciplinary training to 15 Early Stage Researchers (ESRs), offering them an extended and valuable program of international exchanges and secondments through the wide network of partner organisations involved in the proposal. The network builds on the success of previous projects in which beneficiaries have successfully delivered high impact research and knowledge exchange. ReTraCE is specifically designed to train a cohort of new thought leaders capable of driving the transition towards a more sustainable mode of production and consumption in Europe in the next decades, who will directly facilitate the implementation of the recently adopted ambitious Circular Economy strategy of the European Commission, which is closely linked to Sustainable Development Goals (SDGs). Indeed, it is envisaged that ESRs will be employable not only by research institutions, but also by public sector bodies and within a wide range of manufacturing and service industries which will require new professional profiles for realising the transition towards the CE.
