Product description

The machine (name: FLUOSORT) separates a fraction from a continuous stream of plastic material which has been marked with fluorescent substances. Various applications are also conceivable with other materials in which separation via intrinsic material features (for example, density and color) is not possible or impractical and can only be realized by a targeted material marking. In the sorting machine, the fluorescence markers are excited by a laser with IR light at a specific wavelength, and their fluorescence is used in the visible region to identify the marked particles, which are then blown out of the particle stream.

October 2016. Since 2012 the Freiburg company Polysecure GmbH has used fluorescent markers as plagiarism protection. Now the first application for industrial material sorting starts with Rehau AG & Co.

Materials and products are characterized during their preparation by fluorescent markers (tracers). This allows them to be recognized quickly and reliably. This principle has already proven its effectiveness in plagiarism protection. Now it was also transferred to the material sorting (Tracer Based Sorting).
By means of the fluorescence, marked materials can be sorted directly in the waste stream and thus economically. Only one sorting step per marker is required. In addition, there are no "unsortable" fractions.
The markers are robust and temperature stable. They can therefore be used over several extrusions or other processing steps. This means that long-term labeling can also be achieved through numerous recycling cycles. In conjunction with the high sorting quality, a material recycling can thus be implemented at the same quality and performance levels and a down-cycle can be prevented.
The entire waste can be efficiently divided into pure fractions by this process and recycled accordingly. Thus, this technology is useful both from an economic point of view and from an environmental point of view.

Video Tracer-Based Sorting - A Concept - The marking particles (tracers) can be inserted into the label or matrix material in the presented concept. That concept brings a breakthrough in plastic sorting technology, leading the way towards more sustainability.
