Turning Garbage Into Gas

Trash is usually out of sight, out of mind, but occasionally garbage grabs attention – especially when it starts costing a lot. Landfill fees are rising, and with higher costs to ship or truck garbage, a lot of communities are scrounging for alternatives to landfills. Reporter Shawn Allee found one community that hopes a trendy fuel might solve its garbage problem:

For most of us, there’s nothing less sexy than trash. But in part of Indiana, that’s changing.

“One second.”

“Take your time.”

I’m waiting for Jeff Langbehn. He heads a solid waste district in Northwest Indiana.

Lately, Langbehn’s phone is ringing off the hook – from reporters and colleagues. And why are they calling? Basically, it’s because Langbehn’s county is leaning toward doing something new with garbage – something that intrigues trash bureaucrats, maybe even the one in your town.

You see, Lake County Indiana is this close to letting companies convert most of its garbage into ethanol, you know, to run cars. Langbehn says his landfill costs are rising quickly. In his case, that would be 42 dollars per ton.

“The two garbage to ethanol providers were for $17.50 ton. Those savings alone made our board say, hey, we have to pay attention to this.”

And so Lake County Indiana sat down with the ethanol operators.

“And we asked the hard questions like, ‘are there any of these things operating in the country?’ All the standard questions you would ask.”

Shawn Allee: “Wait a minute, when you asked who else has done this and they said, no one, what did you think?”

“Well, the fact of the matter is that the components are being used, and have been used for a very, very long time.”

Sure, some components of garbage-to-ethanol technology have been around for a while. But, if you ask ethanol producers where they actually turn trash into ethanol, they say they can do it in labs, or in test facilities. That’s got some folks in the trash biz nervous.

“I guess I’d say I’m cautious and wary of using any new technology to process solid waste.”

Jeremy O’Brien researches trash for the Solid Waste Association of North America – a trade group. He’s seen landfill alternatives come and go.

“Early on in the 1970s we tried a number of technologies including composting the waste stream, anaerobic digestion, and then we also tried incineration.”

Of those, only incineration survived, but early incinerators had a nasty habit of spewing toxic pollutants, stuff like dioxin, out their smokestacks. O’Brien says incinerators are now cleaner.

His point, though, is that it takes time to improve technology. He worries some communities bent on turning garbage into ethanol could end up holding the bag.

“The facility could fail early on and they’d be stuck without having a place to put their waste.”

Indiana’s Jeff Langbehn says that won’t happen to his county. He says the ethanol companies will cover their own financing, and the county will have insurance as a backup. But speaking of backups, there already is another landfill alternative, right?

Shawn Allee: “Why can’t we just recycle all this and make it into stuff people buy again?”

“There are a number of people out there that could give a rat’s patoot about recycling. And that’s the waste stream we’re having to deal with. The other reality is, recycling is expensive, so I don’t believe it’s a realistic possibility for us to recycle everything, both from a cost standpoint and a societal standpoint.”

So, Langbehn says recycling helps, but ethanol might do more. He says he kind of wishes someone else would try trash-to-ethanol technology first, but it’s worth testing out.

And he says it might be so cheap he won’t even have to hold his nose.
