The efficiency of the tribo-electrostatic separation was evaluated by measuring the purity and recovery of the products. The results confirm that separating (ABS + PS) and (PP + PE) mixtures is feasible. The best separation results were obtained when the materials were stored and processed at an ambient relative humidity of around 50%.
