The recycling of plastic materials is considered nowadays as a major strategic issue, since several million tons of plastic are the subject of recovery and recycling. The consumption of plastics in African countries is continuously growing up and the need of low-cost recycling methods is becoming more pressing. The purpose of this paper is an experimental(More)
Tribo-electrostatic separation of mm-size granular insulating materials is a process widely used in plastics recycling industry. However, the separation of micronized plastics is still inefficient because the adhesion and aerodynamic forces of such particles are most often stronger than the electrostatic forces. The aim of this paper is an experimental(More)
The selective sorting of mixed granular plastics can be achieved by tribocharging in a vibrated parallelepiped chamber of variable height prior to introducing them in a free-fall electrostatic separator. Although such vibrating tribochargers are currently used in industry, no experimental investigation of these devices has been carried out yet. The(More)
