Walthers North American Ethanol Series

I'm almost positive there are rix/plastruct tanks and silos to match that would look just fine.

They do look like it' be nice kits, and easy to assemble.
You could even use some of the Rix structures, such as the Engine house, with some kit bashing to make believable ethanol plant buildings.That and the silos and tanks Rix offers would make a more economical substitute, and even a smaller, taking up less real estate on the layout, and still make it look plausible.

Walthers "Theme" kits have always been pretty pricey to began with.
