The National Biodiesel Board (NBB) is the national trade association representing the biodiesel industry in the United States. Made from sustainable resources such as soybean oil, recycled grease and other fats and oils, biodiesel is the first EPA-designated advanced biofuel produced on a commercial scale across the U.S. Nearly all major U.S. automakers now formally support blends of at least 20 percent biodiesel (B20) in their equipment. Consumers used a record of nearly 2.1 billion gallons in 2015.
