The Approach

SURPASS' researchers will work on new SSRbD polymers in three specific case studies representing 70% of the European plastic demand:

  • Building sector: bio-sourced polyurethane resins (PU) with enhanced vitrimer properties to replace Polyvinyl chloride (PVC) for window frames – with similar insulating properties, and able to achieve a higher number of recycling loops.

  • Transport sector: a new epoxy-vitrimer-based composite integrating nonreleasable fire-retardancy moieties, as an alternative to metal for the train structure, to decrease energy consumption (lightweight material).

  • Packaging sector: MultiNanoLayered (MNL) films involving no potentially harmful compatibilizers to replace currently non-recyclable multi-layers films, associated with a decontamination process for film reprocessing.

The Methodology

In order to support SMEs in the future to design SSRbD polymeric materials, SURPASS will deliver a web-based digital infrastructure. To achieve this overarching objective, the consortium will need to collect existing resources and analyze them to identify missing information for instance, regarding additives and toxicology. In parallel, the three case studies will be launched, which will regularly assess the infrastructure and feed it with acquired knowledge.
Reaching the demonstrator stage, it will serve to increase database content in particular on toxicology and
environmental impact assessment. Finally, once generic decision tools will have progressively been built, it will be challenged to results obtained on the three cases studies.
