Headwall Photonics will be supplying advanced-technology spectral imaging systems to Picvisa (Barcelona, Spain) for use for in-line plastic recycling and sorting. As a provider of sorting solutions for the recycling industry, Picvisa focuses on the ability of hyperspectral imaging to sort and process recycled plastics. By utilizing advanced hyperspectral sensors to capture discrete spectral image data, Picvisa is able to more precisely differentiate and sort between a range of plastics that otherwise would be indistinguishable.
Headwall's Hyperspec NIR image sensors are integrated into Picvisa's new ECOPACK systems slated for worldwide deployment. The spectral range for the hyperspectral sensors will be the Near-Infrared (NIR), spanning 900-1700 nm. Headwall's precision optical technology, based on aberration-corrected gratings in an all-reflective design, allows for deployment of vision technology across very wide conveyor belts collecting and processing information at high speed. This allows Picvisa to significantly increase throughput across the recycling operation. The high spectral and spatial resolution of Headwall's Hyperspec NIR sensor means that even similar material sets (such as plastics sharing the same color) can be distinguished and separated based on the spectral signature of each distinct material.
