Ethanol production from corn residue is poised for a major expansion, with industry experts predicting it could capture 20% of the gasoline market within the next few years. This would create a significant financial windfall for farmers, especially no-till practitioners who are well-positioned to supply the large volumes of corn stover needed by ethanol producers.

Why it matters

The ability to produce ethanol from corn residue, rather than just the grain, represents a major breakthrough that could dramatically increase the scale and economic viability of the biofuel industry. This would provide a new revenue stream for farmers and help reduce reliance on fossil fuels, but also raises questions about the sustainability of large-scale corn stover harvesting.

The details

New enzymes have been developed that can break down entire corn plants, not just the grain, making the process of producing ethanol from corn residue economically feasible. Industry experts expect full commercialization of this technology between 2007 and 2010, with new processing plants potentially breaking ground as early as 2004. Currently, only about 10% of the corn crop is used to produce 2.7 billion gallons of ethanol, which is around 2% of the overall gasoline market. But the expected surge in production could result in ethanol capturing 20% of the gasoline market, a tenfold increase in market share.

  • Ethanol production from corn residue is expected to reach full commercialization between 2007 and 2010.
  • New ethanol processing plants could begin breaking ground as early as 2004.

What they’re saying

“We're now using about 10 percent of the corn crop to produce about 2.7 billion gallons of ethanol. That's about 2 percent of the market.”

“The expected surge in production could result in ethanol capturing 20 percent of the gasoline market, 10 times its current market share.”

— Jim Hettenhaus, Chemical Engineer

What’s next

Industry experts expect to see groundbreaking on new ethanol processing plants as early as 2004, as the technology reaches full commercialization between 2007 and 2010.

The takeaway

The ability to produce ethanol from corn residue represents a major breakthrough that could dramatically increase the scale and economic viability of the biofuel industry. This would provide a significant new revenue stream for farmers, especially no-till practitioners who are well-positioned to supply the large volumes of corn stover needed. However, the sustainability of large-scale corn stover harvesting will need to be carefully evaluated.
