Biodiesel: A Renewable, Domestic Energy Resource

Soybean oil is extracted from soybeans by crushing and pressing the beans to expel the oil. In some cases, a chemical solvent is used to obtain a greater oil yield. One bushel of soybeans (60 pounds) yields about 1.4 - 1.5 gallons of crude oil which can be processed into about 1.2 - 1.4 gallons of B100 biodiesel. One bushel of soybeans also yields about 44 pounds of soybean
