read this aluminum smelting
I read the article and wondered about this quote:
“Recycled aluminium requires only 5 per cent of the energy required to make “new” aluminium. Blending recycled metal with new metal allows considerable energy savings, as well as the efficient use of process heat. There is no difference between primary and recycled aluminium in terms of quality or properties”.
Does this not apply as regards the recycling mentioned in this article?
