Opto-electronic, sensor-based sorting systems for bulk materials, with strength in mining and recycling, are the specialty of OptoSort GmbH, whose free-fall sorting systems such as the APOLLO series use hyperspectral near-infrared (NIR) technology, color detection, and holistic particle scanning to sort construction waste, minerals (limestone, talc), and impurities (gypsum, plastics) with grain sizes from 8-250 mm. Established in 1992 and headquartered in Klagenfurt, Austria, the company can process up to 200 tons per hour, lifting efficiency, cutting energy and water use, and supporting closed material cycles. Serving global markets, it emphasizes robust, maintenance-friendly designs with pull-out valve arrays and remote-maintenance capabilities, and its technology ensures high recovery rates that promote sustainability in mining and recycling.
