It produces 3x as much JRJuice as bio-diesel refineries get from a bushel of soy beans. You are comparing yields of different things. Normally, CAVD reactors produce more pyrolysis oil than the River Process. Pyrolysis normally yields 70% to 90% oil by weight -- the Rivera process yields 66%.
The difference is the water content of pyrolysis oil (c. 15% to 30%) vs. that of JR's.
