A biorefinery in central Iowa is producing natural gas from corn stover.
VERBIO North America CEO Greg Northrup says they are the first company to use agricultural residue to create biomethane gas.
“Most of the renewable natural gas made today either comes from landfills, where they take methane and they upgrade it to pipeline-quality natural gas. Or from wastewater treatment plants where they put it through an anaerobic digestion process to then make methane to then again upgrade it to renewable natural gas.”
The corn stalk bales are the primary feedstock for the Nevada facility and a new source of revenue for area farmers.
