Complete Guide to Cable Recycling: Process, Equipment & ROI
Waste cable recycling is one of the most profitable segments in the recycling industry. With copper prices steadily rising and environmental regulations tightening, investing in a cable separation line offers strong returns while meeting sustainability goals. This guide covers everything you need to know.
1. Why Cable Recycling Makes Business Sense
Every year, over 50 million tons of e-waste is generated globally, with cable waste representing a significant portion. Copper recovered from waste cables commands premium market prices — clean copper granules sell for 85-92% of LME copper prices, while aluminum granules fetch 80-88% of LME aluminum prices.
Unlike plastic recycling where margins can be thin, cable recycling benefits from the high intrinsic value of recovered metals. A well-configured cable separation line can achieve payback within 6-18 months depending on processing volume and local copper prices.
Key Market Drivers
- Global copper demand projected to double by 2035 (IEA)
- Urban mining: e-waste contains 40-50x more copper than ore
- EU and US regulations mandating cable waste recycling
- Circular economy incentives and tax benefits in many regions
2. The 5-Stage Cable Separation Process
Modern cable recycling uses a dry physical separation process — no burning, no water, no chemicals. Here's how each stage works:
Shredding (Primary Size Reduction)
Waste cables are fed into a single shaft shredder with hydraulic pusher and PLC control. The shredder cuts cables into 10-30mm pieces. Overload auto-reverse prevents jams and protects the knives.
Crushing (Secondary Size Reduction)
Shredded pieces enter a heavy duty crusher for further size reduction. This separates copper/aluminum from plastic insulation by impact and shear forces. Output: 3-8mm granules.
Iron Removal (Magnetic Separation)
A magnetic separator removes ferrous metals (steel wire armoring, iron connectors) from the granule mixture. This is essential before gravity/electrostatic separation to prevent iron contamination.
Gravity Separation (Density-Based)
Air classification and vibration tables separate materials by density difference. Heavier copper granules settle, while lighter insulation is carried away by airflow. This achieves 90-95% initial separation.
Electrostatic Separation (Final Purification)
A high-voltage electrostatic separator charges particles differently based on conductivity. Copper (conductive) and plastic (non-conductive) follow different trajectories, achieving copper purity ≥98% and recovery rate ≥99%. This is the critical final step for premium-grade output.
3. Choosing the Right Cable Separation Line
| Model | Capacity | Total Power | Copper Purity | Recovery Rate | Best For |
|---|---|---|---|---|---|
| LVKE-300 | 200-300 kg/h | 75 kW | ≥98% | ≥99% | Small operations, startup |
| LVKE-500 | 300-500 kg/h | 110 kW | ≥98% | ≥99% | Medium recycling facility |
| LVKE-800 | 500-800 kg/h | 150 kW | ≥99% | ≥99.5% | Large-scale processor |
| LVKE-1000 | 800-1000 kg/h | 200 kW | ≥99% | ≥99.5% | Industrial recycling plant |
Key selection factors: daily cable waste volume, available floor space (30-80m²), electrical supply capacity, target copper purity, and budget. Contact LVKESORT for a free consultation and customized recommendation.

5. Environmental Benefits: Dry Process vs. Burning
Traditional cable recycling often involves open burning to recover copper — a practice that releases toxic dioxins, furans, and heavy metals into the air. Many countries have now banned this method.
LVKESORT's dry physical separation process is 100% environmentally friendly:
- Zero water pollution — no washing or chemical processing
- Zero air pollution — no burning, no emissions
- Low energy consumption — 75-200kW total depending on model
- Plastic insulation recycled — not burned, can be sold as recycled plastic
- Compliant with EU RoHS, WEEE, and Basel Convention
