Used Cooking Oil
Used cooking oil is waste or spent cooking & frying oils collected from commercial food factories, restaurants, arena’s, casinos, schools, bakeries, etc. While the majority of used cooking oils are vegetable based, by no means should UCO be considered “waste vegetable oil” as there is inevitably some level of animal fat in UCO, which is naturally derived from the cooking process, and of course some restaurants cook in fats rather than oils.
