On the farming side, most of that 1300 lbs of fertilizer is NOT necessary to grow corn. The 5300 gallons of water is rain, and is going to fall on the fields anyway, and be used by whatever plants are growing there.

On the production side, all that water is NOT waste, it's just water which can be re-used, or put to other purposes. For the heat, any sensible producer would build their ethanol distillery next to a power plant, and use the waste heat from it to do most of the distillation. And of course, the mash that's left is a protein-rich animal food.

And of course the whole thing about the CO2 given off in fermentation & burning of ethanol is worthy of being accepted as denialist propaganda. Since it's part of the ongoing carbon cycle, it does not increase atmospheric CO2.
