Measure and sort challenging black plastic
This company has developed a process for sorting plastic pieces based on material. The company’s tracking-type Raman spectroscopy technology enables the identification of materials with high accuracy in a streamlined process, even when sorting plastic pieces of black shades, as well as black plastic pieces mixed with those of other colors, which have thus far been difficult to identify using traditional near infrared (NIR) spectroscopy. A key advantage of the tracking-type Raman spectroscopy technology is that it uses this company’s measurement and control devices, so the exact position of plastic pieces on high-speed conveyor belts can be detected. The company plans to market a plastic sorting equipment using this method during the first half of this year. — Canon Inc., Tokyo, Japan
