1. Why Recycling Matters
China consumes about half of global refined copper but has limited domestic mine output. Recycled (secondary) copper - from end-of-life products, production scrap and imported recycled raw materials - supplies about one-third of China's refined copper, easing resource dependence and cutting energy use by roughly 80-85% versus primary smelting.
2. Industrial Chain
Recovery: collection networks for cables, electronics, construction scrap and machinery;
Dismantling: sorting, stripping and mechanical separation (increasingly automated and dust-controlled);
Processing and utilization: smelting/refining into anode and cathode, then rod (low-oxygen/oxygen-free), sheet, strip and alloy production;
Quality control: composition verification per grade, impurity limits per GB/T 467 and GB/T 3952 for copper products.
3. Main Clusters
Pearl River Delta: Guangdong (Qingyuan) and Hainan - import-oriented dismantling base;
Yangtze River Delta: Zhejiang (Taizhou, Ningbo, Yongkang) - largest processing cluster;
Bohai Rim: Tianjin (Jinghai) - northern hub with a complete chain;
New inland clusters (Jiangxi, Anhui) growing with cleaner, larger-scale plants.
4. Policy and Standards
Solid-waste import ban (effective 2021) ended raw scrap imports;
"Recycled copper raw materials" (GB/T 38471) may be imported under strict purity/contamination criteria;
Environmental regulations (emission limits for secondary copper smelting) drive consolidation and clean technology;
Output quality must meet the same standards as primary copper (GB/T 467 cathode, GB/T 3952 rod).
5. Outlook
Recycled copper's share is expected to keep rising with electrification (EVs, renewables, grid) increasing copper intensity and scrap availability; efficiency, automation and low-carbon smelting are the industry's main trends.
