TECHNOLOGY | ANTI-COUNTERFEITING


10% concentration of the marked particles can be sorted out so that the purity of the unmarked stream is between 98 and 99% after one pass of sorting, reports Dr Martin Fahr, CTO of Polysecure. In August 2017, Polysecure began a TBS

supply to its foil customers and other players in the market in order to keep the supply chain secure.


Sorting technology Marker technology is progressing in another innovative use beyond counterfeiting. Polysecure’s tracer-based sorting (TBS) technology is now being used to separate similar materials in the plastics recycling stream. While traditional separation of waste materials depends on significant differences in the materials (for example, density or chemical composition), TBS technology can separate even identical materials when one contains a tracer and one does not. Rehau, for instance, manufactures a PVC profile


range with an unreinforced outer layer of PVC extruded over an inner layer of PVC with fibre reinforcement and an added fluorescent Polyse- cure tracer. During recycling the profiles would be shredded into small flakes (typically measuring 2-8 mm) and passed into a TBS sorting machine, which uses a laser to excite the particles containing the fluorescent tracer. A camera identifies the particles with tracer (and therefore glass fibre) and air jets are used to blow out the identified particles from the general stream. With a belt speed of 3 m/s, a


research project in collaboration with Pforzheim University, KIT, Werner & Mertz, and Der Grüne Punkt (Duales System Deutschland) called “Marker based sorting and recycling system for plastic packaging (MaReK).” The project seeks to prove the ability of identifying and sorting specific plastic packaging, independent of the plastic type, so that recycling streams can be further differenti- ated to provide higher value and to increase the ability to recycle packaging. Recovering materials from waste streams can


decrease the use of primary raw materials. “The MaReK approach allows for food packaging to be recycled to the initial application again,” says Dr Michael Heyde at Der Grüne Punkt. The project serves several aims—developing uses for the recycled materials, assessing the marker materials, and optimising waste manage- ment processes. “Moreover, we are observing the innovation effects of the technology in the market environment,” says Dr-Ing Claus Lang-Koetz from Pforzheim University. The researchers will soon be publishing initial results on the technical and financial aspects of the project.
