well, duhh! "leftovers" of ethanol and their value

[poopfuel]

This is the point ethanol naysayers ignore. Coproducts, coproducts, coproducts.

1. I guess the question is how much use can get get out of the glue?

And the other coproducts? If it's just a good sub for ordinary white or wood glue, then it may not be as useful unless it can effectively take on casein based glues, getting rid of the need for millions of gallons of milk to go to stamps and envelopes and into school rooms and crafters' hands.

If the coproduct waste can be burned as biomass, again, I'm good with this - living near a large swath of dying forests and near forests that desperately need people to thinning the trees and using the wood as fuel, I'm a big supporter of biomass energy production.

2. How about growing mushrooms on it?

Mushrooms grow fine on logs, sawdust, even newspaper.
