Triboelectric separation of binary plastic mixture
The separator consists of four cylindrical electrodes. The principle behind the separation technique is based on the difference in the Coulomb force acting on the plastic particles after triboelectric charging. The separation of mixtures of acrylonitrile butadiene styrene (ABS) and polystyrene (PS) using this method was studied.
Triboelectric Series - Triboelectric Effect, Triboelectrification, FAQs
A triboelectric series is a list of substances that is ordered by particular relevant characteristics, such as how fast a substance accumulates a charge relative to other substances on the list. Substances are generally listed according to the sequence of the polarity of charge separation when substances are touched by another body.

Triboelectrostatic separation utilizes tribocharging phenomenon to get different materials charged in opposite polarities and then feed them into electric field to separate them by their different charge polarities. The particle trajectories are deflected in the electric field according to the polarities and the amounts of charge.
Tapping Triboelectric Nanogenerator - MRSEC Education Group
The extent of charge separation is based on the materials chosen. Clear office tape (Scotch brand has a polyvinylchloride derived backing) and aluminum, for example, are far apart on the triboelectric series. As more surface area of the materials come into contact, there is more opportunity for charge separation, which means more triboelectricity.
