Developed by the machine vendor Tomra and the digital watermarks technology supplier Digimarc, the detection unit demonstrated high results across all tested categories of plastic/fibre-based packaging material of 99% detection, 96% ejection and 93% purity rates, on average. The industrial scaled tests are planned to start in 2022.
Timeline and detailed results
The semi-industrial tests of the Tomra/Digimarc prototype started in March 2022 at the Tomra Headquarters in Germany. The purpose was to evaluate the technology by replicating real-world industrial conditions. Success criteria included detection efficiency, ejection efficiency, purity, prototype stability and routine function, ease of programming the sorting operation, and counting capabilities of the prototype.
