well, it's free feedstock. Now, this would make even more sense if they put an ethenol still on site, so it didn't have to go anywhere before being turned into ethanol. I've seen a plan where co2 harvested from power-plant stack gasses is used to feed algae which is used to make biodiesel which results in residue which is fed to pigs, who produce methane and poop which goes to run the power plant and feed the algae. It's all designed into the same space, so little or no energy is lost in transporting byproducts.
