Renewal Processing, Inc. is a family business that converts recycled food by-products into feed ingredients, with its origins in Pennsylvania agricultural work. John Sensenig began experimenting with bakery-waste processing in 1990, and by the end of 1991 was producing a dry bakery by-product for cattle feed; the business was founded as Sensenig Milling Services, Inc. in 1994 and later renamed Renewal Processing. The company presents its work as a way to keep food by-products out of landfills while supplying an alternative to grain for animal feed.
