Experts debate pros, cons of ethanol

CARBONDALE - "Crosscurrents" was an apt term for a discussion on ethanol Tuesday that blended ethical concerns with the main fuel of technology.

"Crosscurrents: Ethanol, Oil and Water in Southern Illinois," an Illinois Humanities Council program, blended presentations on geography, research, environmental resources and philosophy in the SIUC Student Health Center Auditorium.

Dimitra Tasiouras, IHC director of programs and partnerships, said oil and water "intersect in the production of ethanol" and "both involve tough decisions about stewardship of resources."

Panelists were Christopher Lant, professor in the SIUC department of geography and environmental resources; John Caupert, director of the National Corn-to-Ethanol Research Center at SIU Edwardsville; Kenneth Stikkers, SIUC professor of philosophy; and Ira Altman, assistant professor of agribusiness economics at SIUC.

Stikkers said sponsorship of the discussion by the humanities council was appropriate, because ethical issues are involved. "Is the energy gain worth the costs?" he asked.

His concerns include the impact of increased corn production for ethanol in developing countries, with small farmers being driven from their land to make way for crops that can produce ethanol and increasing the gap between rich and poor.

The increasing price of food crops used in ethanol production "is pushing an increasing proportion of the developing world over the edge," Stikkers said. Water is diverted to be used for crops instead of families, and fertilizers are contaminating water supplies, he said.

Lant said ethanol reduces oil imports, reduces greenhouse gas emissions and supports Midwest agricultural economies, but "there are very high resource costs in growing corn for ethanol." Growing corn for ethanol takes a lot of water and degrades water quality, and producing ethanol from the corn takes huge amounts of water, he said.

Caupert, who grew up on a Perry County farm, is now working to facilitate the commercialization of ethanol production. He advocates the alternative fuel to help American farmers increase their profits. Caupert showed a slide from 1933 in Lincoln, Neb., with a service station sign urging drivers to "try corn ethanol."

The ethanol industry can create jobs, decrease U.S. dependence on foreign oil and reduce greenhouse gas emissions. He said the amount of water used in producing a gallon of ethanol decreased from 6 gallons in 1994 to 2.91 gallons in 2007. He expects that soon will drop to 1.5 gallons of water to make a gallon of ethanol.

Altman, who grew up on a farm in Saskatchwan, has done considerable research on creating ethanol from a product he knows well - wheat straw. Using the straw would avoid diverting corn and similar commodities from the world's food supply, he said, but making "cellulosic" ethanol is not yet financially feasible. He is now studying ways to get wheat producers and the ethanol industry together.

"We won't run out of oil," Altman said. "At some point the price will get so high we will go to alternative fuels." Corn ethanol, he said, can provide a "bridge" until users give up oil.

Soy turns ethanol byproduct into pig food

CARBONDALE - A relatively cheap ethanol byproduct mixed with an old nutritional standby might help pork producers cut feed costs.

Gary A. Apgar, an animal scientist at Southern Illinois University Carbondale, has been testing a blend of distillers' grains - the fat, minerals, vitamins and fiber remaining after corn's starch becomes fuel - and soybeans, a traditional protein source for swine.

The combination turns out to be every bit as nutritious as soybean meal and, because grains cost less than beans, it's cheaper, too.

"Soy meal runs about $300 per ton and contains about 47.5 percent crude protein, where distillers' grains cost about $125 per ton and contain 27 percent crude protein," Apgar said.

"If for $250 you can get 54 percent crude protein, it's much more economical."

Apgar's work is part of a larger project aimed at solving two problems facing the ethanol industry: factory emissions in newer plants that exceed U.S. Environmental Protection Agency limits and the need to deal with the increased volume of byproducts that will result from expanded ethanol production.

Seemed kind of far fetched for Colorado, at least for Carbondale
