The Walders built a two stage press for a few thousand dollars that produces Soybean oil for fuel and leaves a high quality protein meal. I like the idea because: 1) It could reduce fuel use and green house gas emissions from the Ag sector (which are large). 2) It is small scale, allowing individual farmers buy or make one and increase their income. 3) It produces a high quality protien meal in addition to the fuel.
