Many laws on recycling are being enacted and attempts made to build a "recycling" society in all fields. Mitsubishi Heavy Industries, Ltd. (MHI) has developed automatic separators for recyclable waste and installed a recyclable refuse recycling demonstration plant concentrating waste recycling technology at the Yokohama Dockyard and Machinery Works of MHI in March 1997. Recyclable waste and collection methods are different among local governments. MHI uses the recyclable refuse recycling demonstration plant to determine the most suitable separation system for each local government and verifies the required performance. Separation system consists of magnet separation, particle size classification, and vibration wind classification, bottle color separators, and plastic bottle separators. This report focuses on bottle color and plastic bottle separators.
