UPCYCLE is a MSCA Doctoral Network of 6 universities and 8 companies from 6 European countries funded by the European Commission. The scope of the project is to generate a cohort of 15 well-trained young researchers with a unique multi-disciplinary set of skills, not limited to technical ones, with the goal of making them the future research leaders or entrepreneurs capable of bringing forward a paradigm shift in the treatment and valorization of hard-to-recycle biogenic waste.
