Can anyone explain why these CFC emissions were necessary in the first place? Are they a byproduct of a manufacturing process that requires filtration or something else?
I only know of CFCs used in refrigerant and cans of hair spray where suitable alternatives are abundant.

- pasabagi 6y agoCFCs are much easier to produce, and better-performing (non-toxicity, fireproofing, etc) than the alternatives. I read also that a certain amount of the CFC releases were apparently coming from illegal sale of heavy tars (industrial waste) for use as weatherproofing. Which is dumb as hell, but also pretty typical.
