This paper discusses recycling of resources in communications cable industry in large

middle and small scales.How to apply the"3R principles"（Reduction

reuse and recycling）of resource utilization in the cable design and manufacturing is presented.The cable processing technology which helps resource conservation and recycling is summarized.The technical issues concerning the recycling of copper scraps

polyethylene and PVC sheathing compounds are analyzed.Different manufacturing processes in other industries and cable industry can be combined to achieve a closed materials loop in large social-scale

which is illustrated by the combined processes to produce polycrystalline silicons and silica optical fiber preform rods.
