Aluminium is a great example of a good metal to recycle. Extraction of the metal from fresh ore is expensive because of the need for electrolysis to convert the aluminium oxide into aluminium. Recycling aluminium only requires the collection of the waste and then for the aluminium to be melted and re cast into the new items. "New" aluminium and "recycled" aluminium are exactly the same in chemical terms so there is no disadvantage in using the recycled stuff. The only real cost for the recycling is the collection and sorting of the waste. Many local authorities now collect cans. The aluminium can easily be separated from the steel ones becuse the steel ones are magnetic. An even better plan would be for people to sort their own rubbish before it is collected separately. It is much easier to have to simply choose which bin to put a piece of rubbish into than having to have some central collection an sorting depot.
The ability for "recycled" aluminium to be a perfect replacement for "new" aluminium is a bit different to paper recycling where the recycling process makes the paper less good. So, although recycled paper is good for many purposes, there is a loss of quality during the recycling process.
Hope this helps. Check with your specification for the exact details that you are required to know.
