We can make ethanol from the grain easily because the grain is mostly
starch. Yeasts are very good at turning starch into ethanol.
Most of the rest of the plant is cellulose. They're working on getting
ethanol from cellulose in industrial quantities and expect success fairly
> SORRY - that should have said take the grain bit and use it for FOOD
When they make ethanol from grain, there's a mash left over that can be fed
to cattle. If I recall correctly it still provides about 2/3rds of the
amount of food value to the cattle as it would have fed directly.
