Question:
Why are aluminum cans hazardous to the ozone layer?


Replies:
I do not know, but since aluminum requires a lot of energy to be rendered from Bauxite, I would guess that there is some potentially harmful pollution emitted during the smelting process.

The only thing I could find about air pollution in the aluminum industry are two articles in the journal "Atmospheric Environment," one in Volume 21, Number 3 (1987) page 617, and one in Volume 22 (1988) Number 3, Page 587. It seems that some fluoride gasses are released in aluminum processing, and maybe these are harmful to the ozone layer, but I do not think anyone has really studied the problem.
