Description

The goal of this project is to set up a markerbased system for sorting and recycling that involves every stage from packaging development and sorting technology to high quality material reuse. The MaRek project demonstrates the usefulness of fluorescent markers for waste management applications. TBS technology, developed and patented by project partner Polysecure, will be piloted and tested in an industrially relevant context as a solution for the challenges of sorting Large Volume Parenterals (LVP) in particular. This will contribute to fulfilment of the requirement of the new packaging law that a higher proportion of waste is recycled. The project will investigate pace, effectiveness, and economic performance of sorting various waste constellations of waste collection under framework conditions applicable to industry. The project addresses the entire value chain of the packaging lifecycle – from design, to process development for marker application and sorting, to material reclamation. The results will lead to new approaches in packaging governance, which will be worked out with relevant stakeholders – together with the technical results of the project, these will serve as a basis for a more sustainable packaging use in the medium term.

Main areas of work

  • Representative recycling of lightweight plastic packaging including determination of the technical residual value (material properties) and the added value potential
  • New or further development and industrial testing of the "tracer-based sorting" method with real batches from separate collection (pilot plant), for this purpose further development of tracer and detection technology
  • Applied innovation research for the  investigation of drivers and obstacles of the developed technology and their application in the complex structure of stakeholders
  • Comprehensive analysis of energy and material flows and an assessment of possible environmental impacts of the developed technology taking into account the life cycle perspective
