Abstract

Nowadays, due to their numerous favorable properties, plastic materials replace other materials in many industries, especially packaging industry, therefore the generation of plastic waste is constantly increasing. Waste plastics can be recycled, which decreases potential harmful influence on the environment and saves landfill space and natural resources. The aim of the research presented in this paper was to evaluate the performance of the electrostatic separator when separating a PET/PVC mixture. The effect of electrode potential and rotor speed on separation efficiency was studied on three different particle size classes (4/3,15 mm, 3,15/2 mm and 2/1 mm). Indicators of separation efficiency for two-component plastic mixture were the concentrate grade and recovery. The best result (100 % grade and 87 % recovery) was obtained by separating coarse particle size class 4/3,15 mm after two separation stages at the electrode potential of 15,5 kV and rotor speed of 35 m/min.
