"Vaughan: In the United States you get ethanol made from corn in the gasoline; in Brazil you get ethanol that's made from sugar. But Iogen uses straw?
Passmore: That's correct. Iogen is not in the business of making ethanol from grains such as corn. We are in the business of making ethanol from agriculture residues such as straw or corn cobs and stalks.
By using enzymes, we turn the cellulose material in this residue into sugars and then turn the sugars into alcohol. This alcohol (ethanol) can be used in today's cars just like grain-based ethanol. In fact, all car manufacturers warrant ethanol blended up to 10 per cent with gasoline.
Cellulose ethanol, as it is known, is not commercially available at this time, but Iogen has the world's largest demonstration plant converting wheat straw into ethanol fuel.
