At first, I thought that you were calling the OP a sweet name, then I remembered the truck that used to pull up to my grandpa's butcher shop. Emblazoned across the side of the big green truck were the words DARLING & CO.
Man, did that truck stink, especially in the Summer!
I couldn't think of the second half of the name. But it is Darling Ingredients, based in Melvindale. As a part of my job with the Michigan Department of Agriculture, I inspected a lot of things related to Animal Industry. Rendering is an amazing industry that finds uses for animal byproducts that would otherwise go in the landfill. Few realize that after all the animals guts, head, feet get ground up, cooled and separated, they use a lot in cosmetics. It is the beef tallow that makes lipstick so smooth.
One religious group would do an annual goat slaughter, about a hundred, in an afternoon. They owned a couple acres with a pole barn, where they kept the goats for a week or two, then held the slaughter there. However, their property was half wetlands and was overseen by 6 or 8 homes. The community wasn't happy with the view and I wasn't happy about the mass "graves" of offal. I made arrangements for Darling to supply steel barrels and haul the mess away.
In addition to the processing of animal byproducts, and the hauling away of the on-farm deas cattle, they pick up all the grease and used cooking oils from nearly every fast food and restaurant. Some goes into bio-fuel diesel. I know, TMI.
