Do real crematoriums even produce smoke at all? Like, there are funeral homes with onsite cremation services in the urban cores of most cities, can’t imagine any government would let them just spew out dead people fumes all willy nilly right in the middle of downtown, wouldn’t they need some serious exhaust filtration before it can be let out into open air? I’ve personally never seen any sort of smoke coming out of any funeral home with a crematorium ever.
