And the waste water from processing the corn gets used too
I've been watching assorted bio-construction. Nobody seems to mention vermin.

That's what always worried me about straw bale construction.

Yeah, there's a guy in EU mainland going nuts about that. I keep thinking "Yeah, buddy, keep doing that and you're going to get to see a rat king."

We have friends with a straw bale house. The builder of our house is a straw bale specialist. His worry for our house was snow leaning against the house rather than pests.
We've had plenty of squirrels in the walls of our stick frame house. I don't think straw bale houses fare any worse.
And I don't think a concrete that uses corn necessarily has a problem with pests any more than a plastic bag derived from biofuels does. In both cases, I don't think the end product is edible per se.
Over the last couple of decades a lot of different alternative building technologies have been promoted with big announcements but then seem to disappear. (ie. Terrabrick, Hempcrete, straw bale, foamed spray concrete, various 3-D printing...)
3-D print corn waste crete makes a lot of sense in regions where you have a surplus of corn waste so it will be interesting to see where they go with this.
One question I have about 3-D in general is without rebar how strong is it against earthquakes where the earth shifts sideways rather than bouncing up and down?

It'd be easy to design & build a cheap 'slider' layer between the foundation and the structure. The concrete could have -also cheap- fiber strands added to the mix.
