Well; thank you Max,

The process in called Cellular Ethanol; An it is the process of using
the waste (What is now called Waste) biomass. The same size field can
out produce Corn 10 to 1 and the emission is reduced by 85% compared to
Ethanol from Corn is only about 25%. The Fermentation uses Gas rather
than Yeast and is getting cheaper every day but is still higher cost yet
than Crude but, as you say, it is competitive right now.

Max; Ethanol is the Chem of the week right now but there are 4 Alcohol
of high interest Methanol, Ethanol, Propanol and butanol. All capable of
replacing Fossil Fuels. Butanol is closer to gasoline than Ethanol
