MIR (mid infrared) – This technology works on a similar principle to NIR, but projects light in the mid infrared range onto materials to be analysed. French company Pellenc ST has been piloting this technology as a more efficient way to separate paper and cardboard claiming efficiency levels up to 90%, an improvement of around 30%.94

  • BOREAS - Pellenc ST also has commercialised this near infrared technology-based on using infra-red detection to determine the weight of the paper, or more exactly the length of the fibres in the celluloid materials. The length of the fibres enables the paper to be identified without any possibility of error and determine if it is of good quality or not.95
