Corn and wheat are not interchangeable lines
Starch content, moisture, handling, regional availability and coproduct markets affect conversion economics. In Canada, fuel ethanol is produced principally from corn and wheat, but plant configuration and procurement differ.
Delivered cost is local
A benchmark grain price needs basis, freight, quality adjustments and timing before it becomes a plant input cost. A facility near surplus grain faces a different procurement landscape from one that must pull grain across a long distance.
Avoid the canola shortcut
Canola is central to Canadian renewable diesel and biodiesel conversations, not the principal starch feedstock for conventional fuel ethanol. The sites keep those pathways distinct.
