Abstract
The authors have developed and commercialized the tribo-electrostatic separator for waste plastics into high-purity materials by type of plastic. This technology employs the frictional charged characteristics which is obtained when different types of plastic are rubbed together. And, it utilizes batch processing to frictional electrification in the standard type of this separator. Therefore, the successive batch processing is applied for continuous separation by plural frictional electrifiers. This report describes an outline of the tribo-electrostatic separator with the successive type batch processing and the results of a continuous separation test. It also describes some pre-treatment conditions which is necessary to obtain 99% or higher purity separation.
