I wonder why they wouldn’t use a different inert gas like nitrogen? It would be a much more humane way to euthanize any mammal, and it’s cheaper to produce on site.
Maybe these aren’t really gas “chambers” and are just open pits, and using c02 because it’s heavier than air?
That’s the key reason. It’s cheaper to run an abattoir like that because of the throughput. Using gondolas you “dip” the batch of pigs in the gas simultaneously, all in the same cage, and rotate it to the unloading bay. No gas containment needed.

Ahh, yeah… Unfortunately that’s kinda what I was figuring.
