Researchers at North Carolina State University have published an inquiry into advanced hyperspectral imaging technology as a potential jumping-off point for sorting municipal waste. The study, published in the journal Matter, discusses the scientists' use of powerful optical sensors to analyze the wavelengths of light reflected against various materials as conveyed through a pixelated image. "Hyperspectral imaging is a powerful tool that allows us to see what human eyes or standard cameras can't," explained Lokendra Pal, an E.J. Learn moreA large body of these "fingerprints" can better equip local recycling systems as they sort through municipal waste — in particular, identifying materials that can be salvaged for various recycling endeavors. This research to speed up and enhance automated sorting techniques through hyperspectral imaging can help pinpoint more salvageable materials and transform our recycling management systems for the better.
