1.Sources of waste cable wire
Old cables wires are very common scraps in communication engineering, and you can often see large piles of leftover materials. Most of the waste cables wire are disposed as scraps directly, but some old cables wires are also recycled and reused.
In general, old cable wire sheath is low plastic in PVC materials as it cannot be directly reused (generally, the grinding materials inside contain hybrid copper wires), and it must be re-granulated. But since the chlorine contained in the cable sheath is medium, the requirement to the granulating machine is not high. A machine with a single screw is enough to work, and most PVC granules are reused in producing new cables and wires.
2. The recovery value of waste cables wires
The main purpose of recycling waste cables wire is to refine various precious metals such as copper, aluminum and plumbum, which have high utilization value.
3. Common methods for recycling waste cables wires (Sheath Removing)
Manual stripping: The efficiency is low and the cost is high by using this method and the labor working environment is usually very poor;
Burning: It’s a traditional method. You can get copper by burning off those waste plastic wraps, but it will cause thick smelly smoke and pollute the air. Meanwhile, the surface of the copper wire will be seriously oxidized in the process of burning, which will reduce the recovery rate of copper. This method has already been strongly prohibited by various countries.
Using cable wire stripping machine: It still needs a person to operate the machine to strip the sheath of the cables, and the efficiency is also very low. Besides, it’s only suitable for thick cables.
Chemical method: Chemical processing scrap cables and wires was proposed in 1990s. A significant disadvantage of this method is there is no appropriate way to dispose those waste liquids which can cause great pollution to the environment. So, it’s seldom adopted.
