The U.S. rendering industry collects and safely processes more than 50 billion pounds of animal byproducts each year. Rendering is the process of converting these materials into fats and proteins used in animal feed. The rendering industry provides services for the safe collection of these materials, transports the materials in biosecure, leak-proof trucks and uses heat (240 to 290º F) to dehydrate and separate the fat and solid materials. This seminar session will focus on the quality and safety of rendered products. Building on a background of the industry and its markets, globally recognized speakers will describe the value of using rendered products as an ingredient in feed, as well as explaining the process, safety, quality control, and research that is involved in the rendering process.
