The tribo-electrostatic separation of PP and LDPE followed the same separation principle as PP and HDPE, since the polyethylenes are adjacent in most tribo-electric series (Table 1). Hence, the PP particles acquired negative or neutral charge, while the LDPE particles acquired positive charge and were attracted to the electrostatic electrode.
