Changing the yield rate from the current GTECH rate to a Midwest agricultural rate of 586 L of pressed oil per hectare (63 gal/acre) and retaining the 99% conversion efficiency, production could range from 2.4 million L (648,000 gal) of sunflower biodiesel in Milwaukee (0.06% of the RFS2) to 9.2 million L (2.4 million gallons) of sunflower biodiesel in Indianapolis (0.2% of the RFS2). Potential contributions from Chicago, Columbus, and Detroit all fall within this range.
