They mix 225g sand with 50g of corn starch.

It's more "sand based" than "corn based".

in concrete, cement makes up less than 25% of the mix, and here corn is like 20%, so I think when you're comparing this class of materials (concrete, epoxy granite, concrete), it makes sense to describe in terms of the binder even if it is a smaller % of the complete product.

All concrete is more aggregate than binder… but it’s the binder that matters from an emissions perspective.
