Copper is known to be one of the most resistant metals around. Meaning it can last for a long time. One of the most significant properties that copper possesses is that it is recyclable. Bearing the same similarities to aluminum, it requires less energy to produce new copper through recycling than to produce new one through mining. In addition, mining new copper not only is harmful it also emit toxic gases such as Sulphur dioxide which may pollute and cause side effects to the environment.

Thus it is cheaper to recycle old copper than to extract new one as the value of recycled copper is still worth up to 90% of the cost to an original copper. It is often found in our electronic gadgets such as mobile phones, computers and other machinery parts.
