Abstract

|
|
The generation of waste cable has been continuously increased as a production of electrical and communication media are extended. The current recovery methods, such as mechanical peeling, incineration, solvent extraction and pyrolysis, seems inadequate because they are either hard to apply in some cases or environmentally unacceptable. It has been shown that copper can be effectively separated from the jelly filled type cables using a soybean oil treatment method. As a result, jelly compound is vanished from the wire by soybean oil bath and waste wires are separated copper and PE by the mechanical chipper. This is a more environmentally friendly method than burning, and considerably faster than stripping.
