UNISENSOR Sensorsysteme GmbH is a family-run, innovative high-tech company in the field of process analytics and control based in Germany. They developed a sorting system based on laser spectroscopy which separates previously inseparable plastics, such as dark or black plastic mixtures, with highest precision and speed, allowing the long-term recovery of valuable raw materials. With POWERSORT 200 they developed a system that steps in where visual or other established systems and detection methods fail. The system uses a highly efficient and accurate detection method based on high-speed laser spectroscopy: it identifies the good material in a plastic flake or granulate stream using its specific opto-electronic spectrum and sorts it from various foreign and contaminating materials in just a single process step. Sorting using laser spectroscopy means that electronic scrap will in future be able to be reused in new electronic equipment. So waste can now become a resource.
