You’re not subtracting the btu’s chargeable to the co-product. If you’re going to charge all of the energy cost of the distillation to the ethanol, then the CO2, corn oil and distillers grains are all free. (What could be better than a process which produces edible oils and high protein feeds for free?)

So?
>If you’re going to charge all of the energy cost of the distillation to the ethanol, then the CO2, corn oil and distillers grains are all free.
I realize that; I am not analyzing the “bonuses” given from waste- or by-products, but only the cost of the production of ethanol.

But they truly aren’t free if the cost-of-production-and-transportation of the Ethanol consumes MORE BTUs than the Ethanol contains in-total.
If that is the case then what you are terming as free “edible oils and high protein feeds” is actually costing something: the loss in BTUs.
