The overall objective of SURPASS project is to lead by example in the transition towards more Safe, Sustainable and Recyclable by Design (SSRbD) polymeric materials. The SURPASS consortium of 13 partners consisting of research and technology organizations and industries will: 1. Develop SSRbD alternatives with no potentially hazardous additives through industrially relevant case studies targeting the three sectors representing 70% of the European plastic demand: - Building: bio-sourced polyurethane resins with enhanced vitrimer properties to replace insulating PVC for window frames - Transport: lightweight, therefore less energy-consuming epoxy-vitrimer, as an alternative to metal for train structure, anticipating emerging use of non-recyclable composites. - Packaging: MultiNanoLayered films involving no compatibilizers to replace currently non-recyclable multi-layers films. 2. Optimize reprocessing technologies adapted to the new SSRbD systems to support the achievement of ambitious recyclability targets. 3. Develop a scoring-based assessment that will guide material designers, formulators and recyclers to design SSRbD polymeric materials, operating over the plastics' entire life cycle, including hazard, health, environmental and economic assessments. 4. Merge all data and relevant methodologies in a digital infrastructure, offering an open-access user-friendly interface for innovators. SURPASS will in particular address its results to SMEs, representing more than 99% of enterprises, and therefore has an outstanding potential to contribute to the transition towards a green economy.
