K: Steinert shows sorting of black plastics

The sorting of black plastics into pure grades to close recycling loops will be the focus of Steinert's presence at K Trade fair.
According to Steinert, UniSort BlackEye is the world's first machine capable of pure-grade detection and sorting of black PE and PP plastics, and has been used aorund the globe since 2016. Picture: Steinert

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.

If the material be sorted contains a mix of black plastics, it can be seperated into pure-grade polymer fractions. Picture: Steinert

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.
