I think this is poorly written in the article... Likely the Co2 gas is used to power bolt-guns which are in turn used to stun larger animals like cows before slaughter.

No, the slaughter industry does in fact use CO2 to asphyxiate animals. It even has a fun euphemism, "Controlled Atmosphere Stunning".

Interesting, I didn't realize that was done at scale... As the comment above me said, seems harsh to use CO2 for that...
