Black plastics represent a particular challenge because they cannot be detected with the optical sorting technology found in standard recycling plants. Since 2011, Steinert is working on detection solutions for those materials. Sophisticated air flow technology also makes Steinert the only company to be able to cost-effectively sort flat and lightweight black materials.
What’s more, the pure-grade separation of black polyolefin’s (PO) into their constituent parts, such as polyethylene (PE) and polypropylene (PP), but also polystyrene (PS) and acrylonitrile butadiene styrene copolymers (ABS) allows polymer granulates to be replaced by mint-condition recyclates.
