Pure biodiesel feed stock for clean energy

Valley Proteins’ sustainable biodiesel feed stock is produced from the animal fats and used cooking oils we collect and recycle in our conversion facilities. Our fats are used to produce 100% biodiesel, and biodiesel/diesel blends, for use in diesel engine systems. Our biodiesel feed stock meets the quality standards specified by the American Society for Testing and Materials (ASTM D 6751) for use in diesel engines, and has passed the testing requirements of the 1990 Clean Air Act amendments.
