Made from an increasingly diverse mix of resources such as recycled cooking oil, soybean oil and animal fats, biodiesel is a renewable, clean-burning diesel replacement that can be used in existing diesel engines without modification.  To be called biodiesel, the fuel must meet the strict quality specifications of ASTM D6751.  It is the nation’s first domestically produced, commercially available Advanced Biofuel. NBB is the U.S. trade association representing the entire biodiesel value chain, including producers, feedstock suppliers, and fuel distributors, as well as the U.S. renewable diesel industry.  Biodiesel is produced in nearly every state in the nation and supports more than 64,000 jobs nationwide.
