摘要：

Raman Spectroscopy is able to identify plastic components, similar to infrared absorption. This paper shows the potential application of Raman spectroscopy to post-consumer plastic recycling when massive and accurate sorting processes are required. We developed a high-speed Raman apparatus for scanning with an appropriate wavelength region of less as 1.5 milliseconds, and an analyzing methodology that uses a discrimination function. We successfully implemented this technique in a shredded plastic recycling plant. The online sensing system successfully carried out more than three hundred cycle decisions per second.
