The goal of this project was 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 demonstrated the usefulness of fluorescent markers for waste management applications. For this purpose, the use of the TBS technology developed and patented by the project partner Polysecure was piloted as a possible solution and then tested in an industry-relevant way, especially for the sorting of plastic packaging (LVP). The speed, effectiveness and economic efficiency of sorting different compositions of the collection fractions were investigated under industry-relevant boundary conditions. The project addressed the entire value chain of the packaging life cycle from design to process development for marker application and sorting to recovery of the materials. Approaches to a new packaging governance were elaborated with the relevant stakeholders and, in the medium term, should serve as a basis for more sustainable packaging use in addition to the technical results of the project. In this way, the developed process can make an important contribution to increasing the recycling rate required by the new packaging law.
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
