This workshop aims to bring together researchers, engineers, and industry players to discuss innovative strategies for recycling and upcycling polymers, in a context where the transition to a circular economy for materials is becoming a scientific and societal priority.

Despite recent progress in the sorting, collection, and regeneration of plastics, current processes still struggle to achieve sufficient environmental and economic performance to ensure true circularity. Chemical, enzymatic, and mechanical recycling approaches each have advantages and limitations in terms of efficiency, selectivity, and carbon footprint. At the same time, upcycling, which aims to transform plastic waste into higher value-added materials, opens up new perspectives but also poses challenges in terms of technical feasibility, chemical compatibility, and the sustainability of the products obtained.

The objective of this workshop is to promote multidisciplinary dialogue between chemists, process specialists, LCA experts, and material flow analysis experts in order to identify current barriers and technological, economic, and regulatory levers that can be used to strengthen the circularity of polymers.

We therefore wish to collectively explore avenues for the design, modification, and reuse of polymer materials that will enable the concepts of recyclability and recovery to be fully integrated into the sustainable development strategies for the materials of the future.
