Electrostatic Separation of Chopped Waste Electric Cables

E - Waste Recycling by Electrostatic Separation

This chapter discusses the problem of Waste Electric and Electronic Equipment (WEEE) as one of the largest growing waste streams globally, the influence of the product complexity and liberation in separation, and the basics of electrostatic separation. A very short review of mechanical separation processes is given and research conducted on one fraction of CRT TV set is presented. A CRT TV set ...

Tribo-aero-electrostatic Separation of Micronized Waste Plastics

Electrostatic separation of granular plastics mixtures has become a wellestablished technology, with industrial applications in the area of waste electric and electronic equipment (WEEE) recycling. The aim of this work is to validate the feasibility of selectively sorting of micronized waste plastics in a two-rotating-disks-type tribo-aero-electrostatic separator. The experiments are carried ou...

Electric Field Investigation in MV PILC Cables with Void Defect

Abstract—Worldwide, most PILC MV underground cables in use are approaching the end of their design life; hence, failures are likely to increase. This paper studies the electric field and potential distributions within the PILC insulted cable containing common void-defect. The finite element model of the performance of the belted PILC MV underground cable is presented. The variation of the elect...

Electrostatic vibration-to-electric energy conversion

Ultra-Low-Power electronics can perform useful functions with power levels as low as 170 nW. This makes them amenable to powering from ambient sources such as vibration. In this case, they can become autonomous. Motivated by this application, this thesis provides the necessary tools to analyze, design and fabricate MEMS devices capable of electrostatic vibration-to-electric energy conversion at...
