Using five laser beams that can detect different types of plastics, this sorting robot puts plastics into six different piles, depending on their content. The robot uses photonics sensing technology developed by IDEC Co., LTD. and PARC, along with robot technology of Mitsubishi Electric Engineering (MEE) Co., LTD.
Right now, Japan recycles only PET and PS, but many more types of plastics are used. The robot could be a big emissions-saver by opening up opportunities for further plastics recycling.
