In Indiana, corn is widely grown and used for ethanol production, but this biofuel isn’t the most climate-friendly option. Researchers are exploring corn stover—the stalks, leaves, and husks left after corn is harvested—as a promising alternative.
This agricultural residue could serve as a sustainable biomass source for biofuel, offering environmental benefits while providing an additional income stream for Indiana farmers.
Corn-based ethanol production requires significant fossil fuels, including those used in fertilizers and farm equipment. While corn remains profitable for farmers, as they can sell it for both ethanol and livestock feed, the production process has a higher carbon footprint than other biofuels.
Biomass from corn stover, on the other hand, has the potential to produce cleaner fuel with less environmental impact.
Jennifer Pett-Ridge, a researcher from the Lawrence Livermore National Laboratory, has studied ways to remove carbon dioxide from the atmosphere and co-authored the Indiana’s Roads to Removal report. Pett-Ridge notes that many crops have leftover materials, like corn stover, which could be used to create biofuels.
“About half of that gets incorporated into the soil—and we want to keep doing that—but about half of it literally kind of rots on the surface,” she explains. By utilizing this leftover material for biofuel, Indiana could reduce agricultural waste and contribute to a cleaner environment.
Switching to corn stover as a biofuel source presents farmers with an opportunity to enhance climate-friendly fuel production while maintaining soil health.
Since some of the crop residue can still be incorporated back into the soil to maintain its quality, only a portion needs to be used for biofuel. This approach balances environmental needs with agricultural practices.
Corn stover as a biomass fuel represents an important step toward more sustainable energy in Indiana. As research and technology in biofuel production evolve, using agricultural by-products like corn stover could help Indiana farmers lead the way in reducing carbon emissions.
