Black plastics represent a challenge when recovering plastics because they cannot be detected as easily with optical sorting technology found in standard recycling plants. Steinert GmbH, Cologne, Germany, offers technology that allows black plastics to be sorted from the general waste stream and to be sorted into pure grades. The technology enables plastic processing companies to respond to the challenges of the circular economy and in a cost-effective manner; it also enables them to be equipped for all the processes involved in plastic recovery and processing, Steinert reports in a news release.
Since 2011, Steinert reports that it has been developing technology for challenging sorting applications and providing forward-looking reference projects, which document that plastics and the environment are compatible. The company reports that it was one of the first companies to be able to detect black plastics and positively separate them, allowing recycling rates to increase, Steinert reports in a news release. Sophisticated air flow technology makes Steinert one of the only companies to be able to sort flat and lightweight black materials in a cost-effective manner. Additionally, the pure-grade separation of black polyolefins into their constituent parts, such as polyethylene (PE), polypropylene (PP), polystyrene (PS) and acrylonitrile butadiene styrene (ABS) allows polymer granulates to be replaced by mint-condition recyclables.
Steinert plans to showcase some of these technologies that recycle black plastics during K 2019, which takes place Oct. 16-23 in Düsseldorf, Germany. The company will have experts ready to talk to customers at stand B23 in Hall 9.0.
