This study covers the triboelectrostatic separation of Polyvinylchloride (PVC) materials from mixed plastics such as polyethylene terephthalate (PET), polyethylene (PE), polypropylene (PP), and polystyrene (PS). The PVC material generates hazardous hydrogen chloride gas resulting from the combustion in the incinerators. The laboratory scale triboelectrostatic separation system consists of a fluidized-bed tribocharger, a separation chamber, a collection chamber and a controller. Negative and…

Waste of electronic medical devices contains different type of valuable plastics intermixed, generating incompatibilities and limiting the reusing potential, so that the separation of plastics is a
Set-Point Identification and Robustness Testing of a Triboelectrostatic Separation Process for Mixed Granular Plastics
Using Taguchi's methodology, it was possible to predict the most robust process design, with respect to the uncontrolled variation of granule size and ABS content, which revealed that the separation efficiency significantly depends on the high-voltage applied to the electrode system and on the position of the splitters, but is less affected by the material transport velocity on the tray of the vibratory feeder.
The Effect of Charged Granules Agglomerations on the Electric Field Distribution of a Tribo-aero-electrostatic Separator
Recycling of plastics from WEEE requires, first of all, separation on polymer types with various technologies being currently employed for this operation. A new solution, the single-step

The Triboelectric Separation for Plastic Sheets
An apparatus for separating a specified plastic from other kinds was devised. It consisted of a triboelectric section and a separating section with both polarities. Various plastic sheets were
Electrostatic separation of plastics by friction mixer with rotary blades
A mixture of plastic pellets or waste plastic pieces is electrostatically separated. The mixture is charged by friction in a mixer and falls through a horizontal electric field of 4 kV/cm into three
Slug characteristics of polymer particles in a fluidized bed with different distributors
Pressure fluctuations in a fluidized bed (0.38 m-I.D.x4.4 m-high) of 1.23-mm polymer particles (LLDPE) were measured with different distributors. Slug characteristics (slug frequency and slug rising
