A Shell station near Ottawa, Canada is leading the way in offering cellulosic ethanol at the pump. While many companies, including some in Canada, are working on making the biofuel, not many have gotten it to the refueling station. Blended at 10 percent with unleaded (E10), the ethanol is made by Iogen, which has a process that uses enzymes to chemically break down wheat straw until the cellulose molecules become ethanol. The most interesting part of this ethanol is that it isn't obtained from feedstock, but from agricultural waste. Both Shell and Iogen stated that the factory could produce up to 40,000 liters (10,500 gal) of cellulosic ethanol a month from their demonstration plant in Ottawa. Thanks to Chris for the tip!
UPDATE: It's not the first time.
