Aluminium Foil - Recycling, Source Reduction and Energy .

Used aluminium has always been an important source of 'new' metal. According to industry estimates, about two thirds of aluminium in use is eventually recycled because it is so much cheaper to re-melt it in its metallic form than it is to extract the metal from the original ore.
