Powering a Town With Pig Manure

With skyrocketing crude oil prices much of the nation’s attention has turned toward alternative fuels. While many people are focused on ethanol production, one small town is looking at turning waste from humans and hogs into electricity. In a few months, the town will break ground on a 10-million dollar processing plant. It hopes to become the first town in the nation to run completely off renewable resources.

With skyrocketing crude oil prices much of the nation’s attention has turned toward
alternative fuels. While many people are focused on ethanol production, one small town
is looking at turning waste from humans and hogs into electricity. In a few months, the
town will break ground on a 10 million dollar processing plant. It hopes to become the
first town in the nation to run completely off renewable resources. The GLRC’s LaToya
Dennis reports:


To get where we’re going, you have to pass through small town after small town and
acres and acres of cornfields. Reynolds, Indiana is a farm town of about 500 people. It’s
hard to find on most maps. And it’s pretty easy to overlook. After all, there’s only one gas
station and three restaurants. But what Reynolds is doing is hard to overlook. Charlie
Van Voorst has lived there for a long time and is now the town president. He says the town is
going to provide its own electricity and it’s not going to burn fossil fuels like coal or
natural gas.


“Town board meetings went from talking about the neighbor’s dog in your yard to now
talking about million dollar decisions about what we’re building.”


What the town of Reynolds is building is a new power plant powered by the by-products
of the surrounding farms, chiefly, pig poop. The plant will use technology to pull
methane and other gases from animal and human waste. The gases will then power
engines and steam turbines. Coming out on the other end is electricity, and leftover solids,
which can be used for fertilizer.


(Sound of pigs)


Within just a few miles there are around 150 thousand pigs. That makes for a lot of
waste:


“Well, this is the bacon.”


Bill Schroeder is a local pig farmer. He’s standing in the middle of a thousand hogs.
They’re about knee high and weigh around 300 pounds each. They’re constantly eating
and pooping.


“It don’t smell to me, does it smell to you. When you walked in here, did you smell?”


Actually, it did smell, but Schroeder thinks it smells like money. He says he’s willing to
give the waste his pigs produce to the town to turn into electricity. After the waste is
processed, farmers will get a higher quality fertilizer back for their fields. But Schroeder
says some farmers still might hesitate because they’re not being paid for their pig waste.


“There should be return. Anytime you invest money, you expect a return. I mean if
you’ve got a CD in the bank you expect a return on that CD. It’s no different from
investment in machinery, hog buildings or anything else.”


Obviously, some of the financial incentives still have to be worked out, but Reynolds
town officials say there are good reasons besides money to take the town off the existing
power grid. Right now, Reynolds gets its energy from coal. That puts a lot of carbon into
the air. Methane processing produces less carbon dioxide than coal.


Jody Snodgrass is managing director for Rose Energy. That’s the company building the
processing plant. He says the project has another environmental benefit. It reduces the
amount methane from pig manure that’s released into the atmosphere because it’s
captured and used to make electricity.


“The increase of methane causes increased cloud formation. Also causes decreased ozone
layer and basically contributes to global warming as does carbon dioxide and several
other compounds. And if you can reduce those or eliminate those, that obviously is a plus
for the environment.”


That’s the reason the town of Reynolds is getting the support of the state in its effort to
become energy independent. Although everyone’s not on board yet, town president Charlie Van
Voorst is excited about what’s to come. He says small town farming communities haven’t
seen a development this big in more than 100 years:


“Oh, my goodness. Since I’ve grown up, golly. I suppose you could talk about the –
something to this magnitude would be when electricity came into our community.”


Town officials hope Reynolds is powered by pig poop and other alternative fuels by
2008. They say if things go well, their town could become the model for other small farm
towns across the country.

Cleaning Waterways From the Bottom Up

Polluted sediments sit at the bottom of rivers and lakes across the Great Lakes region. They can affect water quality, wildlife and human health. More than 40 highly contaminated areas in the region have been identified by the EPA’s Great Lakes Office, but so far only about half of those sites have been cleaned up. This fall, dredging is taking place in at least three of those hot spots – all on rivers. The Great Lakes Radio Consortium’s Karen Kelly reports on the challenges of cleaning up a river bottom:

Polluted sediments sit at the bottom of rivers and lakes across the Great Lakes region. They can affect water quality, wildlife and human health. More than 40 highly contaminated areas in the region have been identified by the EPA’s Great Lakes Office.
But so far, only about half of those sites have been cleaned up. This fall, dredging is taking place in at least three of those hot spots, all on rivers. The Great Lakes Radio Consortium’s Karen Kelly reports on the challenges of cleaning up a river bottom.


(Sound of dredging)


Geologist Dino Zack stands on the steps of a mobile home overlooking the St. Lawrence River. He watches as barges glide in and out of an area contained by a 38 hundred foot long steel wall. Each barge carries a crane that periodically drops a bucket into the river bottom, pulling up sediment contaminated with PCBs. The goal is to remove 80 thousand cubic yards of contaminated sediment. Zack’s trailer is the EPA headquarters for the dredging project. He’s an independent contractor working for the federal government, which is spearheading the operation. And he’ll spend the next couple of months watching the Alcoa-Reynolds Company remove the chemicals they once dumped in the river.


“I’ll observe them while they’re collecting their data to make sure they’re following the work plan. Then, I’ll bring all the data back, assemble it into tables and review it.”


Zack isn’t the only one keeping a close eye on the dredging project, which began in June.
There’s another EPA scientist here, as well as two members of the Army Corps of Engineers who are supervising the work. There’s also a representative from the St. Regis Mohawk reservation, which is downriver from the contaminated area.
The EPA ordered Alcoa-Reynolds to clean up the pollution in 1993. The PCBs were present in a flame retardant liquid the company used in its aluminum smelting process.
Over the years, the liquid drained into the river, contaminating sediments along the shoreline. The most polluted area contains 2000 parts per million of PCBs. That equals about one bad apple in a barrel-full. The goal is to leave only one part per million of PCBs in the sediment. Anne Kelly is the EPA’s project director for the site.


She says achieving that level in a river environment is a challenge.


“One of the biggest problems with dredging a river is that you’re working without really seeing where you’re working. The other problem is the issue of re-suspension, that whenever this bucket hits the sediments, it stirs up sediments and then it settles out again.”


One of the biggest concerns is that the disturbed sediments will move downstream.
In this case, they’d only have to travel a mile to reach the drinking water intake for the St. Regis Mohawk reservation. That means toxins could make it into the drinking water.
Local people have also expressed fears that the PCBs could contaminate the air as well.
The dredging project was temporarily suspended this summer when residents on nearby Cornwall Island complained of respiratory problems. But air quality tests found the dredging wasn’t to blame. Ken Jock is the tribe’s environmental director.
He says in addition to air and water quality concerns, the local people would like to see a healthier fish population. Some species have been contaminated with PCBs. And he says that’s why the tribe supports the dredging.


“We know the PCBs will be there in a thousand years and we’ll be here, and we’ll still want to eat the fish. So we think that any solution has to be a permanent solution.”


The Alcoa-Reynolds Company had wanted to place a gravel cap over the chemicals rather than dredge. But the EPA ordered them to remove the PCBs. Rick Esterline, the company’s project director, says they’re fully cooperating with the government.


“You’re required to clean it up, that’s the rules and regulations that we have in our country. Whether they come at you with court orders or whether you do it, it’s still you have to do it.”


The project is expected to cost the company 40 million dollars. That includes the eight million dollar reinforced steel wall around the contaminated area. Alcoa-Reynolds is also using a special electronic bucket to remove the sediment. The EPA’s Anne Kelly says this has become the bucket of choice for Great Lakes dredging projects.


“Based on the information that will be transferred to the operator on the barge, he’ll know if that bucket is completely sealed, which is very helpful because a clamshell bucket will begin to close and hit a rock… he won’t know it’s still open partially and begin to pull that up through the water column with materials basically pouring out of it.”


Kelly says every cleanup project requires a different approach. In Michigan, General Motors is using an environmental bucket and silt curtains to dredge the Saginaw River.
Engineers in Michigan’s Pine River built a steel wall and emptied out the water inside before dredging. The dredging in the St. Lawrence is expected to finish in November.
And it’s possible it won’t reduce the PCB levels to one part per million. The cleanup at the nearby General Motors plant fell short of that goal. If that happens, the EPA will require the company to cap the river bottom – and monitor the sediments, the water and the fish indefinitely. For the Great Lakes Radio Consortium, I’m Karen Kelly.
