For the past few years, ethanol’s been
a political darling, but lately it seems the
party’s over. There’s concern the industry’s
using too much corn. That’s contributing to
rising food prices. Well, some companies want
to avoid the controversy. Reporter Shawn Allee explains they want to make ethanol from
stuff we leave behind at the dinner table:

To give you a sense of how touchy the ethanol issue’s gotten, consider what happened to Presidential
candidate Barack Obama. Last year, he supported mandates to add billions of gallons of ethanol to our
fuel stream. But recently, on ‘Meet the Press’, he was defensive.

“If it turns out, we got to make changes to our ethanol policy to help people get something
to eat, that’s the step we take. But I also believe ethanol has been an important
transitional tool for us to start dealing with our long-term energy crisis.”

Obama and other ethanol backers say we’re not stuck with corn-based ethanol. We can use wood chips
or energy crops like switchgrass.

But this cellulosic ethanol is a ways off.

First, the technology’s expensive. Plus, farmers don’t even grow energy crops now.

So, some companies hope to make ethanol from stuff that doesn’t need farms at all. It would come
from garbage cans, like this one at a coffee shop.

“In that receptacle there’s a lot of paper, and there’s some food bits and there’s some
scraps. So, we’re able to turn that into sugar. And the weak sugar, then we ferment, we distill into alcohol, and we get the ethanol.”

Zig Resiak is with a start-up company called Indiana Ethanol Power. He says garbage could compete
with corn.

“If you have a corn-to-ethanol facility, you’re going to pay for the feedstock. Trash, as a feedstock, we don’t
pay for it. The municipalities actually pay us to take the trash, just like a
landfill will take the trash.”

Resiak’s company isn’t the only one to figure this out. At least three other ethanol firms are asking
cities to hand over their trash, and cash. Besides being cheaper, there might be other advantages to
using garbage for ethanol.

Bob Dineen is with the industry group the Renewable Fuels Association.

“We have garbage all across the country.”

Here’s why that matters.

Before it makes it to the pump, ethanol needs to be blended at refineries. Dineens says those
refineries are far from corn farms and rural ethanol plants, but refineries are often close to big metro
areas, and big-city trash.

“A company that is able to produce from local landfill refuse – he’s clearly going to have an
advantage in terms of transportation, feedstock costs, and all the rest.”

Well, that’s the theory, anyway. The market hasn’t tested garbage-based ethanol yet.

So, what exactly is stopping companies like Indiana Ethanol Power from giving it a go?

Resiak says it’s simple – cities just haven’t been willing to part with their trash.

“Municipalities are very comfortable with putting it in the back of a truck and letting it go to the landfill. They don’t think about it twice. But for us to come in and say we’re going to
take it cheaper and we’re going to save you millions of dollars a year on your tipping fee – that’s different
and that’s kind of scary, and they want to take a good, strong look at that.”

Resiak predicts by the time cities do come around to the idea, there will be even more companies ready to
take garbage bags out of their hands.
