Griffin Industries' pioneering role in the development of biodiesel is the foundation of the company's renewable energy efforts. Griffin began producing commercially viable biodiesel in the 1990s, even before the U.S. Department of Energy recognized biodiesel as an alternative fuel.

Griffin's animal fats and recycled greases, as well as plant oils such as soybean oil, are recycled into a quality biodiesel fuel called Bio G-3000^™ Premium Biodiesel Fuel. It is safe for the environment, biodegradable and produces less air pollution than diesel fuel. Bio G-3000 can be used in place of diesel fuel without engine modification or performance reduction and is the fastest growing domestic alternative fuel.

Griffin's biodiesel operation in Butler, Kentucky, is the longest continuously producing, flexible-feedstock biodiesel production facility in the United States. In addition to being a vertically integrated biodiesel producer, Griffin Industries supplies primary feedstock to many commercial biodiesel producers around the country.

Griffin's biodiesel operations are accredited through the National Biodiesel Board's BQ-9000 program. BQ-9000 is a voluntary fuel quality assurance program which provides customers the peace-of-mind that Griffin's biodiesel will meet all related ASTM D6751 specifications.
