Sorting mixed plastics by color and type

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

  • The Unisort Film EVO 5.0, for two-dimensional plastic, uses a circulating airflow to stabilize the films on the conveyor 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 airflow stabilizes small items, enabling 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 present its solutions on its stand E24 in hall 9 of the K Show, as well as on the VDMA stand CE01 and the R-Cycle stand CE07, at the Circular Economy Forum.
