In order to deal with the problems facing the plastics processing industry research, work is focused primarily on designing, developing and testing a variety of separation and sorting techniques able to recover plastics from wastes, which can be re-used or re-processed to form new products. In this regard, technologies developed in mineral processing can be of great help. Various techniques for separating plastics materials have been recently developed. These techniques can be divided in two main categories, i.e. wet separating techniques and dry separating techniques. This paper presents the recent progress in separating plastics reviewing the potential of the available techniques.

“…V. Gente et al (Gente et al, 2003(Gente et al, , 2004) studied cryo-comminution and electrical separation of medical packaging blisters, it was demonstrated cryocomminution process improves the effectiveness of size reduction and thus promotes liberation of aluminum from plastics. Though high recovery of plastic and aluminum was obtained, more energy was adopted apparently by cryo-comminution.…”

“…4,5) Plastic wastes including PVC can release hazardous substances such as hydrogen chloride gas and dioxins during disposal procedures and its additives can be released by leaching and contact transference. 6,7) Also, mixed plastic wastes are difficult to recycle because of their inferior characteristics. In this regard, the disposal of plastic wastes has become an important issue all over the world due to their increasing volume and the decreasing landfill capacity for disposal.…”

In this research, on the basis of the control of electrostatic charge, a laboratory-scale triboelectrostatic separation for separating polypropylene (PP) and acrylonitrile-butadiene-styrene (ABS) in seaweed-drying net frame plastic wastes has been carried out. High density polyethylene (HDPE) in a charger material selection tests using a vertical-reciprocation system was found to be the most effective materials for a tribo-charger in the separation of PP, and ABS. In lab-scale triboelectrostatic separation tests using the HDPE pipeline charger, the charge-tomass ratio (nC/g) of the mixed PP and ABS increased when the air velocity was adjusted to over 10 m/s. The optimum splitter position estimated by Newton's separation efficiency ( n ) was a position +4 cm from the central. Furthermore, under the conditions of over 385 kV/m electric field and less than 30% relative humidity, a PP grade of 99.70% and a recovery of 92.30% could be obtained.
