- Save raw materials and electrical energy by not having to extract the aluminium from the bauxite.
- By recycling used aluminium, it uses only about 5% of the energy used to extract it from bauxite.
- Recycling used aluminium saves space, as dumping the unwanted aluminium requires the finding of space.
