Fluorescence marker-based sorting technology

Factsheet 4: Tracer-Based Sorting with Fluorescent Tracers - Efficient and flexible sorting of plastic packaging

The German Packaging Act calls for a significant increase in recycling rates for plastics. In order to be able to produce high-quality recyclates, plastic articles must be separated by type. However, there is currently a lack of satisfactory identification options for the many different plastics.

MaReK

Marker-Based Sorting and Recycling System for Plastic Packaging
July 2017
December 2020

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.

revolPET

Development of a Recycling Technology for PET Waste Plastics from Multilayer Material and Other Waste Composites
October 2017
March 2021

revolPET aims to develop a solvolytic recycling process for materials made of PET (Polyethylene Terephthalate) in multilayer or mixed materials and to carry out experimental trials. Inactive patents for solvolysis of single-variety PET waste form the basis for this research: those solvolytic processes will be enhanced into a continuous waste treatment concept that can recycle PET waste.
