"Food grains are not used in ethanol production, only seed quality grains."

And your source for that statement would be what? Can you define a 'seed quality' grain? Thanks for your time.

I think he meant feed corn, not seed.
as for the other question
Try look up "how ethanol is made"?

Oh, and also look up how much of the corn grown in America is used for human consumption (less than 1%) and even much of that goes unsold and ends up in landfills some years.

The USA is a food IMPORTER not a food exporter. (we import 76% of our food needs) Much of which gets tossed out.
