From March 25 to 28, 2025, the Lorraine Fab Living Lab ENSGSI-ERPI hosted the kick-off of the TechTraPlastiCE project, an initiative aimed at strengthening the role of universities in their interaction with the socio-economic world in the circular economy within the plastics industry. This ambitious project aims to promote capacity-building among universities in Latin America to explore various modes of sustainable collaboration between the academic world and socio-economic players. Sharing innovative practices is a key element in fostering the implementation of circular economy policies in Colombia, Argentina and Chile, while promoting a just transition.
