I'd think you could build some machine to (re)harvest nitrogen from the air and it would eventually be free. But maybe that doesn't exist / super hard to do...

Or you could just run a pipe from the building's furnace or generator exhaust to the pig-gassing room and use the CO2 your facility is already generating.
