How many gallons of biodiesel can you make from a bushel of soybeans?
According to the U.S. Department of Agriculture's (USDA) Farm Service Agency, one
bushel of soybeans yields approximately 1.4 gallons of biodiesel. Soybeans contain about 20% oil, so it takes almost 7.3 pounds of soybean oil to produce a gallon of biodiesel. U.S.
soybean production reached about 2.5 billion bushels in 2003, according to the USDA National Agricultural Statistics Service. The United States produces about 20 million gallons of
biodiesel per year using soybeans and other feedstocks.
Soybean oil and used cooking grease are the two main feedstocks used to produce biodiesel in the U.S.
