Why metals might not be recycled?
Some metals become contaminated, meaning they are unable to be recycled. Take motor-oil cans for example. The metal in question has come into contact with harmful toxins — even if you clean the cans, you can’t guarantee that all the chemicals have been removed. As a result, it would be unwise to recycle that metal.
Why is it difficult to recycle some metals such as copper?
For example, copper for electrical wiring requires a very high purity, so if wiring is made from recycled copper, the waste copper will need processing before being melted again into copper for wiring. However, steel used in construction doesn’t need such a high purity.
