Re-using ferrous and non-ferrous waste is simply common sense. Theoretically, these materials can be processed and reused indefinitely. In other words, there is no use-by date on ferrous and non-ferrous metals.
4 good reasons to re-use ferrous and non-ferrous metals: :
It reduces the demand for the world’s raw materials
It requires less energy than producing new metals
The amount of environmentally damaging waste products is reduced when compared with production using primary raw materials
It reduces the need for junk yards, incineration, etc.
Did you know that if all the metals from the 2.3 million smartphones annually sold in Denmark were recovered, they would include 195kg of gold, 841kg of silver, and 2,415kg of tin? Source: Stig Irving Olsen, lecturer in sustainable production at the Technical University of Denmark.
