Just 1 remark: There can never be 100% recycled Alu for all Alu products - why:

- some Alu will intentionally stay at the place there it's used; (and thats good, better than re-use, btw)

- there are losses in the recycling chain; may be just 5%, still, that alone would add 0.4 tons/ton

- nobody can just claim that "he is using" recycled Alu only; why not? Because, there will not be enough of this stuff, the bottleneck is not using it, the bottleneck is the Alu-return-fraction; or: using add. recycled Alu is always just taking it away from someone, who has used it anyhow (before you do).

- so what? For Alu, just use the mixed emission factor of all Alu used in your country.
