Aluminum cans and the ozone layer
Name: Bill J Petraitis
Why are aluminum cans hazardous to the ozone layer?
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.
