BlueFire Ethanol bets on household trash

BlueFire Ethanol expects to start construction of a plant within weeks that will convert landfill waste into the fuel ethanol.

CEO Arnie Klann on Thursday provided a timeline for the company's trash-to-ethanol projects at the Jeffries Global Clean Technologies conference, saying that there are two other larger plants already being pursued.

He argued that making ethanol from municipal solid waste is more economical than making it from corn, as is done now, or from agricultural and forestry wastes. Its process can make 70 gallons per ton of waste stream going into its machines.

BlueFire Ethanol intends to locate its plants at landfills, which reduces the need to transport the feedstock. The ethanol will also be produced in urban areas where there is the demand for the fuel, which keeps transport costs down, he said.

"We can use waste streams that are not universally used by other proponents of cellulosic ethanol," Klann said.

The U.S. renewable fuel standard mandates that a significant portion of ethanol comes from cellulosic sources, like wood chips or agricultural residue like corn cobs or the leftover bagasse from sugar cane plantings.

The price of the feedstock is one of the biggest factors in ethanol's end price. Producers need to locate their facilities close to their feedstock source to be economical.

Cellulosic ethanol producers typically are either using thermochemical processes, specialty microorganisms, or enyzmes to break down feedstocks into sugars which are then fermented into ethanol.

By contrast, BlueFire Ethanol is using concentrated acid hydrolysis, where trash is sprayed with sulfuric acid, dunked into a bath, and then pressed. The resulting sugars are then fermented into ethanol, while the acid is separated and recouped for later use.

Competitor CleanTech Biofuels is also using acid hydrolysis in its pilot ethanol plant, which it expects to open later this year. Another company interested in trash as a feedstock is Coskata, which has a conversion process that uses high-pressure gasification and bacteria to produce sugars.

Klann said the company expects its first 3-million-gallon-per-year facility to be constructed this year in Lancaster, Calif.

It expects to complete applications for a Department of Energy loan this year to build a second plant, capable of making 17 million gallons per year, in an undisclosed place. The third plant on the drawing board would produce 55 million gallons annually.

After 2009, the company then intends to build more--at a pace between five and seven plants a year--in the Northeast and Southeast U.S., Klann said. He also anticipated international expansion with its modular plant design.

"When you are talking about waste streams, there are maybe 15 or 20 landfills in the U.S. that could sustain a 100- to 150-million-gallon-per-year ethanol plant," he said. "We're looking at those locations to build out, but the vast majority of landfills will handle that 17 million-gallon-per-year size."

This sounds like an interesting idea. I don't know that I'm a fan of ethanol, but I'm supportive of anyone doing something to reduce reliance on oil, foreign or domestic. Of course, if its a clean way to eliminate landfill waste and future garbage I say go for it. We should be growing corn to eat, not to fuel cars.

Thank god someone turned the the light bulb on other than politicians cramming use of foodstuff for manufacture down our throat of ethanol.It or alcohol can be made out of anything which will rot from grass clippings on! Also motorcycle running on purely ethanol took special carb. used twice as much ethanol than gas to run.Politicians usually can't even change a flat tire yet make decisions mostly bad to enrich themselves not the people??America is waking up!

Amen! What we need (and this is evidence of that) is less government intervention. People are quite resourceful, and will be far more productive with the government trying to put its nose in everyone's business.

I would rather see them making butanol than ethanol.

[mlamonica]

As it turns out, they can make butanol from waste as well. I think they are keeping an eye on the demand for butanol.

[galeso]

I want one just big enough for all my junk mail.

I agree that we should eat corn not turn it into fuel. i am a fan of ethanol, hydrogen, and anything that will ween us off of oil. The corn for ethanol is the biggest boondoggle that has been pulled over us in a long time. 1 acre of corn makes 350 gallons of ethanol. 1 acre of algae makes 5,000 to 7,000 gallons of ethanol. Wonder why we are not speeding up the developement of this? Politicians from both parties in all corn states. I live in Georgia and do a lot of driving for work. I see fields of corn now instead of cotton, grass, soy, and peanuts. This drives up the price of these products.
If we are to make the jump to ethanol, hydrogen, and electric cells, then we are going to need a lot of electricity. This is also why we need more nuclear energy. We should get more oil now, build more nuclear now, and plan to get of oil. I am sick that we have to buy oil from the mideast and venezuela. Dont go to Citgo, it is Hugo Chaves's company.

Stopping alcohol use can be able to prevent or reduce health problems that are made worse by alcohol use, such as liver damage. Prevent harm to your unborn baby if you are pregnant. Reduce related family concerns or relationship problems.
