Sorting Mixed Plastics by Color and Type

Cologne-based Steinert will present sorting solutions for mixed plastic waste at the upcoming K Show in Dusseldorf.

• The Unisort Film EVO 5.0, for 2-dimensional plastic, uses circulating air flow to stabilize films on the conveyer so that they can be detected by near-infrared sensors and sorted. The near-infrared sensors used by Steinert use hyperspectral imaging technology to detect very small differences in composition, allowing the system to distinguish PET bottles from PET trays, for example.

• The Unisort Finealyse is optimized to achieve high purity in flake sorting. A high-speed belt with directed air stream stabilizes small objects, resulting in high quality sorting with minimal material loss.
• The Unisort Blackeye enables the detection and separation of black and dark plastics. Using the mid-infrared range of the spectrum, black mixed plastic can be separated by resin, including PE, PP, PS, and ABS.

Steinert will show its solutions at its stand E24 in hall 9 at K Show, as well as presenting at the VDMA stand CE01 and the R-Cycle stand CE07, in the Circular Economy Forum.
