Abstract

The article reviews present situation and recent technology trend of 4R (Recycle, Reuse, Reduce, Repair) in electric power wires and cables. Based on the result of questionnaires to electric power companies and buyer of removed electric wires and cables, the amount of removed electric wires and cables and present situation of 4R were investigated. Many conductors of removed wires and cables are recycled as conductors again, but plastic materials of them that recycled again as plastic materials of wires and cables is not enough. Therefore, in order to improve the ratio of recycling, application of the recycling material to products other than wires and cables is considered and the new technology for recycling into the material of wires and cables is studied.
