Tele-communication cables of the waterproof type are widely used in internet service, high-speed internet access and voice and video services. As often in the case of non-waterproof cables, atactic polypropylene
flooding compound is applied between their protective sheaths about the cable core to prevent water entry. Recently the manufacture of traditional copper multipair cables is in decline due to the newly installed fibre optic technology. 6500 tons of jelly cable waste was evolved in 2008. Jelly cable wastes should be properly handled for environment-friendly recycling and one of the fundamental recycling process is to separate the copper and plastic fractions from jelly filled cables and to produce clean copper granules free from jelly, which is the main topic of the present study.
