Spectral Imaging Transforms Recycling

PAS brings spectral imaging to the growing recycling and waste management industry.

For the recycling industry, legacy ‘RGB’ technologies are unable to pick out the precise spectral characteristics that distinguish similar-looking types of plastic or paper products.

Although hyperspectral imaging sensors have been used for some time within the recycling industry, Headwall’s application-specific approach and a focus on robust, reliable instrumentation means that this technology is continually evolving and keeping page with the rapidly changing recycling landscape across the globe.

Headwall’s hyperspectral sensors collect image data across hundreds of spectral bands with exceptional resolution. The output of this process is a hyperspectral cube comprising all the spatial and spectral data within the field of view. When analyzed, the data leads to efficient, sensible, and profit-generating decisions.

Headwall’s fast-frame-rate Near-Infrared (NIR) Hyperspec® sensors cover the range of 900nm to 1700nm and are perfect for high-speed lines found within the recycling industry.

  • Compact, rugged design for durability and stability
  • Very wide field of view
  • 320 spatial bands and 166 spectral bands
  • Extremely high signal-to-noise

With this technology, the chemical composition of similar-looking materials is clearly distinguishable. Headwall’s Hyperspec III software not only controls sensor operation but integrates seamlessly with downstream robotics to complete the identification and sorting cycle.

Since recycling is a multi-billion-dollar industry, it pays to be precise. And Headwall is able to produce hyperspectral sensor solutions that allow you to achieve real competitive differentiation by extracting more value from your high-speed operation.
