This plant receives guts, feathers and blood from chicken processing plants and turns it into protein for animal food. This is one smelly dirty job. I live a couple of miles from one in Cumming GA and the smell at times is horrible. The name of the plant is American Proteins.
Haven't experienced it first hand. However, work with a guy who has had years of experience at nearly all points in the chicken process--all bad. Particularly terrible: rounding up chickens to be taken from a "house" to a processing facility. Ammonia levels so strong that people have been known to pass out and/or get chemical burns! (worst case) Then there’s the pain of dealing with literally tens of thousands pecking chickens.
Boy, you aren't kidding, that smells!! There's a rendering plant for farm animals not far from here, and even though its back from the road, the smell will come up through the air ducts in your car as you're driving past, and it lingers there until you're a mile down the road. If you should be unlucky enough to follow an animal in the bed of a pickup down the 2 lane road to the plant, whew, it'll just about knock you over! Mike should do this job, I know I sure wouldn't!!
