Ethanol Grabs Nation's Attention

(AP) COON RAPIDS, Iowa -- A tractor trailer rig rumbles into the Tall Corn Ethanol plant. Corn pours from openings in its belly to bins underground, where conveyor belts and buckets haul it to gleaming steel silos rising 13 stories above the Iowa plains.

The 40-acre distillery turns corn into alcohol in quantities that would make a moonshiner drool. Instead of white lightnin', the brew is converted to ethanol, a fuel that makes money for farmers and is seen as a possible solution to today's high oil and gas prices.

Like the other modern-day stills dotting the Midwestern landscape, the Coon Rapids plant reached capacity soon after opening -- within 12 days, to be precise.

Ethanol production in the United States is growing so quickly that for the first time, farmers expect to sell as much corn this year to ethanol plants as they do overseas.

"It's the most stunning development in agricultural markets today -- I can't think of anything else quite like this," says Keith Collins, the U.S. Agriculture Department's chief economist.

The amount of corn used for ethanol, estimated at 2.15 billion bushels this year, would amount to about 20 percent of the nation's entire crop, according to department projections.

Even as ethanol devours corn and pushes prices higher, the president and Congress are calling for even greater ethanol use. Wall Street cannot seem to get enough of ethanol-related investments. Automakers are speeding ethanol-capable vehicles onto the road.

Yet the ethanol industry is not without its critics, who question whether tax incentives provided by Congress are really needed.

The enthusiasm for ethanol makes farmer Lynn Phillips want to grow more corn. Phillips helped raise the money for the farmer-owned Tall Corn plant, which opened in 2002 as a way to make more money by processing every kernel of locally grown corn.

"We saw train cars after train cars of raw material being shipped away and value being added somewhere else," said Phillips. Now, the corn "is still going out on train cars -- it's just going out in the form of ethanol and distillers' grain."

Corn can cost more to grow because it needs heavy applications of fertilizer. Right now, Phillips plants corn on about half his 2,000 acres and soybeans on the rest.

Inside the ethanol plant, corn is ground and mixed with water to make mash. It is heated and mixed with enzymes to convert starch into sugar and fermented with yeast to make alcohol -- just like making moonshine. Hanging in the air around the 500,000-gallon fermenting tanks is the smell of sweet, white wine.

The mixture is kept just below 90 degrees Fahrenheit. Yeast seem happier below that temperature, general manager Owen Shunkwiler hollers over the hum. Shunkwiler works for South Dakota-based Broin Companies, which invested in Tall Corn and is responsible for its operations.

After fermentation, the mixture is boiled to remove water, then dehydrated to boost the alcohol content. Before leaving the plant, a denaturant, or poison, is added to make the alcohol unfit for drinking. Then the ethanol is ready for shipping to fuel storage terminals that will blend it with gasoline as it goes into trucks for distribution to gas stations.

Also yielded in the process is livestock feed. Corn kernels minus the starch are left over -- think South Beach for cows. Every 56-pound bushel makes about 17.4 pounds of grain feed, according to the Agriculture Department.

Tall Corn produces 150,000 gallons of ethanol each day, enough to power an estimated 272 cars for an entire year if they ran on ethanol alone.

But automobiles do not run on pure ethanol. Instead, ethanol is combined with unleaded gasoline to boost its octane rating and reduce emissions.

The most common blends are 10 percent ethanol, approved for any make or model sold in the U.S., or 85 percent ethanol, known as E-85 and used in specially made flexible fuel vehicles. About 5 million vehicles in the U.S. can run on E-85; more are in production.

In Iowa in April, regular unleaded gasoline was selling for $2.71, E-10 for $2.65 and E-85 for $2.33.

With demand comes expansion. In Iowa alone, three new ethanol plants opened last month. The industry likely will outpace a mandate from Congress to pump out 7.5 billion gallons a year by 2012, according to Collins.

Meanwhile, lawmakers envision vastly more ethanol in the nation's automobiles. Sens. Tom Harkin, D-Iowa, and Richard Lugar, R-Ind., are pushing to require 60 billion gallons of ethanol and soy-based biodiesel by 2030.

An expansion that big would require sources for ethanol besides corn. Ethanol is made from sugar cane in Brazil, which meets about half its fuel demand with ethanol. Sorghum, another feed grain, accounts for about 3 percent of U.S. ethanol, according to the Agriculture Department.

Research is under way on other potential sources, such wood fibers and residue from crop harvesting.

"When the price of anything gets high enough, then all kinds of substitutes come out of the closet," Collins said. "That's what's going on now. As long as the price of oil stays high, where ethanol is profitable, this industry is going to keep growing."

I had a propane vehicle once, drove it for a couple of years.

It was good for the engine as the oil stayed so clean you had to force yourself to change it.
It was also about 30% down on power, and a real nightmare if you ever "ran out of GAS".
You cannot just pick up a can of propane and pour it in the tank!

The E85 will suffer from similar problems of low power and poor mileage.

My experience with propane illustrates the real hurdle for nearly every "alternative" fuel. They just do not work as well as gasoline.

Propane as an alternative has been available for decades, the car I had was converted when it was new, in 1974!

People will not avail themselves of these alternate technologies until-
1. They work as well as gasoline.
2. They are forced to.

#1 will work far better than #2, but I fear #2 is more likely in this century.

"where ethanol is profitable, this industry is going to keep growing."

I wonder if this will be a colossal mistake. I read the following in a local paper:

The EPA has identified ethanol plants as significant air polluters and deals have been reached to curtail harmful toxic emissions, but not in this case.

Citizens have long complained about the sickening sweet, pungent odors that travel miles from the AE Staley (Loudon plant).

British owned and globally known Tate & Lyle is a top producer of ethanol and high fructose corn syrup. Archer Daniel Midland, agri-giant ethanol producer is a large stockholder of Tate & Lyle, parent company of AE Staley. Currently, Tate & Lyle/Staley will joint venture with DuPont Chemical Co. on a new industrial bio-based polymer. This new process is expected to add 35 tons per year of air pollutants, 7 tons identified as ammonia. DuPont will not identify the composition of the remaining 28 tons of pollutants.

A well-respected Loudon pediatrician has repeatedly testified of an increase in respiratory problems with children patients. A grassroots citizens group, Clean Air Friends-Clean Air Kids, Inc. held a drive and collected over 2,600 names to petition Gov. (Phil) Bredesen and Betsy Child, TDEC commissioner for relief. Citizens voiced concerns about respiratory, and catastrophic diseases and worries about sick children. Local, state and federal officials and plant owners appear indifferent to concerns.

Special interest groups lobby for the introduction of ethanol bills under the guise of cleaning the air that we must breathe to require use of an inefficient ethanol grade of fuel. Another bill proposes to give away some $6 million in gasoline taxes. Ethanol tax incentives have raided the Federal Highway Trust Fund of $7.1 billion since 1979 bestowed to big agribusiness. A loss of billions of tax dollars amount to highway robbery of roads and bridges in need of expansion and repair and reduced highway safety. The General Accounting Office, concluded ethanol subsidies have not paid off in reducing U.S. dependence on oil imports.

Experts believe ethanol actually contributes to ozone and smog formation, especially when vehicles use it as the 10 percentethanol, 90 percent gasoline blend. Studies show a 10 percent mix of ethanol and gasoline would put more chemical contributors to smog into the atmosphere than gasoline alone and suggest a 10 percent blend is the worst possible combination. Not until the ethanol portion of the fuel mixture approached 80 percent did it fall below the ozone contribution potential of standard gasoline.

The Loudon (Staley/Tate & Lyle) plant purportedly uses 700 tons of coal per day. Adding yet to more air pollution, toxic diesel emissions since ethanol must travel by rail, truck, or barge. Experts believe it takes more energy to make ethanol than is saved using it. A Sidney newspaper reported, up to a third of Australia’s 10 million cars will not operate satisfactorily on 10 percent ethanol. Industry sources added, 30 to 40 percent of cars cannot perform satisfactorily or may even be damaged with E10.

Twenty-two years ago, farmers were lead to believe AE Staley would buy Tennessee corn. Sadly, some mortgaged farms to later learn corn would instead be bought from the Midwest. Big money, special interest and politicians promoting ethanol should not come at the expense, health, and future of its children and residents of Loudon County and West Knoxville; this is not a fair trade off, especially when ethanol will do little good to reduce air pollution. One thing’s for sure, corn-fed politics will cost taxpayers a bundle!
