The Company sells these products nationally and internationally, primarily to producers of animal feed, pet food, fertilizer, bio-fuels and other consumer and industrial ingredients including oleo-chemicals, soaps and leather goods for use as ingredients in their products or for further processing. Effective January 2, 2011, as a result of the acquisition of Griffin, the Company's business operations were reorganized into two new segments, Rendering and Bakery, in order to better align its business with the underlying markets and customers that the Company serves.
