From Wikipedia, the free encyclopedia
Yellow grease is derived from used cooking oil from the fast-food industry. It is used to feed livestock, and to make soap, make-up, clothes, rubber, detergents, and bio-diesel fuel.
It is distinct from brown grease; yellow grease is typically used-frying oils from deep fryers, whereas brown grease is sourced from grease interceptors. Yellow grease can also refer to lower-quality grades of tallow (cow or sheep fat) from animal rendering plants.
Thanks to all. This thread has been helpful. Now that we've mulched every year and built up some soil, Armadillos are decimating all of my flower beds but I'd rather not kill them.
