As long as you know it is a given that blending ethanol reduces VOCs overall, feel free to pursue that argument. Older ethanol plants released VOCs, but they are now required to install hardware which removes them. Burning ethanol releases fewer VOCs than burning gasoline.
The amount of distillers grains and other co-products produced are easily verified contacting an ethanol company or reading their financial reports. Your attempt to paint co-product production as a conspiracy is flaccid and limp.
That is not a distillers grain issue. That is grain issue period. If you feed any cattle grain only they get sick. It has nothing to do with the grain based feed that comes from ethanol production. Don't even try to take it there.
Also, the coproduct aspect itself is a huge level for misrepresentation of raw physics.
Somehow the USDA finds their energy requirements were much larger than previously thought, and then turns around and says their yields are even higher than ever.
You make the assumption that cattle can consume corn byproduct in large quantities, and that the market for it hasn't reached saturation.
When in fact there's now a huge glut of DDGS, and it can't be fed to cattle in more than 1/5th their diet, or else it causes them to get sick, because it's too acidic.
...CONT...Only 60% of the farming emissions for corn can be put against ethanol when you take into account that the corn used in ethanol is still put to work as the originally purposed cattle feed. It would have been grown anyway.
Yes but the GHG "credit" given to the DDGS can't be easily verified.
Or verified at all because the USDA keeps all their new accounting methods secret.
The exact opposite of what peer review does.

Also, considering you want to focus on that conclusion. Did you read the last sentence?
"This study did not include speciated hydrocarbons"
What do those do? They increase ozone formation.

How can that be?

No it doesn't. It says it depends on the car you test and the test you run. Read the entire conclusion section.

So your NCSU study actually agrees with the one I posted.
Lower CO emissions,
but higher aldehyde, nitrogen oxide smog emissions, and "Total HydroCarbon" emissions (Aka VOCs)
As expected.
