“The use of vegetable oils for engine fuels may seem insignificant today, but such oils may become, in the course of time, as important as petroleum and the coal-tar products of the present.”

Rudolf Diesel, April 13, 1912

Domestically Produced Biodiesel Vegetable Oils

The Biodiesel Process The Biodiesel Process

One bushel of soy produces 1 ½ gallon of diesel Energy ratio approximately 1 to 3
