Brewing Greener Beer

It takes a lot of water and a lot of grain to brew a good beer. And once that beer is made, there’s a lot of spent material and water left over. This excess is usually just considered waste. But two guys in the Great Lakes region decided to start a brewery that would focus on reducing pollution and waste and then re-using whatever was left over.

It takes a lot of water and a lot of grain to brew a good beer. And once
that beer is made, there’s a lot of spent material and water left over. This
excess is usually just considered waste. But two guys in the Great Lakes
region decided to start a brewery that would focus on reducing pollution
and waste and then re-using whatever was left over. They wanted to
show how helping the earth could also help business. The Great
Lakes Radio Consortium’s Annie MacDowell reports:


(ambient pub noise)


It’s a busy summer night at The Leopold Brother’s of Ann Arbor
Brewery. People have shown up to unwind after a long week. Some are
here to listen to the live band. Others to play a rowdy game of Pictionary
in the beer garden.


But mostly, people are here to drink the beer.


Brothers Scott and Todd Leopold own and run the brewery. A family resemblance is
obvious between the brothers.


But their roles in the business are totally different. Todd Leopold brews the beer. He’s a
big, friendly guy who seems at home in a comfortable-looking pair of old
overalls. Todd went to the Siebel brewing school in Chicago and got hands-on
training in four different German breweries. He uses techniques he learned over there in
his own facility.


His brother Scott Leopold is an environmental engineer, educated at
Northwestern and Stanford. Scott spent years helping big companies
save money by using environmentally sustainable business techniques.


But four years ago he decided to put his money where his mouth was.
One night, at a bar in Colorado, the two brothers came up with the idea
to combine their talents and start the world’s first zero-pollution brewery.


They wanted to build the model, then show people that it could really work.
Their idea was met with some skepticism by family and friends. Simply put, they
thought Scott and Todd were nuts. And Scott says they weren’t all wrong.


“Most of the entrepreneurs who are out there will tell you if they knew what they were
getting into before they got into it…they probably wouldn’t have done
it. We might not be alone in that.”


But so far the idealistic business venture has proved to be a success. Scott and
Todd have reduced the volume of a typical brewery’s waste by 90 percent.


To accomplish this, Scott and Todd designed a brewery where every detail was taken into
account to conserve resources.


“What we wanted to do was put science ahead of marketing…to ensure that anyone could
look within our production processes to ensure that it would stand up to the rigors of
science within the environmental engineering world.”


(ambient sound of brewery)


In the brewhouse, stainless steel machines gleam like they’ve just been washed. They’re
not brewing today… that only happens about once a week. But the factory computer is on
and its small, colorful graphics are showing everything that’s happening in the facility.


The computer helps cut down on the brewery’s waste by tracking and regulating all
energy and water use. So there’s always an accurate record of what was
produced versus how much of the raw materials and energy was consumed.


Todd Leopold says this helps him brew better beer.


“When you know everything that’s going in and everything that’s going out, if suddenly
that changes or there’s a spike you know there’s a problem and you’re able to track it
down. So it’s really helped me run a much tighter ship.”


All the other devices in the brewhouse are specially tailored to reduce waste. In fact,
they’re so efficient that Leopold Brothers generates 25 percent less solid waste residue
and buys 25 percent less grain than most small breweries.


That means they’re saving money.


Scott Leopold says their profit margins are nearly a quarter higher than they would have
been if they hadn’t made the investment in better equipment early on. But even with all
the complex equipment, there’s still some spent grain and water left over.


It’s all put to good use. The used organic malt and hops make great food for
animals at organic farms. Excess water from the brewing process is used in the
greenhouse in the back.


Pots of basil for the menu and moonflowers for the beer garden grow in there.
Conservation even extends beyond the brewhouse to the brewery’s decor.


Fat vinyl green tubes with zippers up the sides snake across the ceiling. They’re part of a
more energy-efficient heating and cooling system. And old doors hammered together
make up the bar.


The Leopold Brothers pay the same attention to detail when it comes to marketing their
product. The labels are made from vegetable-based inks. And they use recyclable
cardboard boxes as packaging.


But the brothers want to have an impact on brewing beyond just their own facility.


Todd says they have to start off small.


“We’d love to see the larger, world class…well, not world class, but world size breweries
that distribute their beer internationally to adopt some of the things that we do. It’s just
very difficult to infiltrate the corporate culture as opposed to where there’s one or
two owners. You sit down with them, have a beer, and say this is how you need to do
things. It’s much easier to have an impact on that level, I believe.”


Scott and Todd Leopold say the big breweries have adopted some conservation
techniques simply to save money…but they still generate a lot of waste water.


Scott thinks they could reduce the amount by introducing new machinery and changing
their cleaning techniques.


But U.S. Environmental Protection Agency environmental scientist Erik Hardin says the
big breweries will have to be shown that trying more new things will help the bottom
line.


“With most any big business, pollution prevention steps seem to be incorporated after the
people in charge have been convinced thoroughly that these things can actually save them
money.”


And the Leopold Brothers say that is the exact mission of their brewery …to show, by
example, that sustainability means profitability.

On March 31st, the U.S. Environmental Protection Agency will be holding public
hearings across the country about changes to Clean Air Act regulations, called New
Source Review. The Great Lakes Radio Consortium’s Annie MacDowell has more:


The proposed changes to the New Source Review would relax standards for pollution
controls on power plants that are more than 25 years old.


Environmentalists worry the new standards could allow old power plants to pollute more.


The EPA will hold forums in Albany, N.Y.; Dallas, Texas; Romulus, Michigan; Salt
Lake City, Utah; and the EPA’s Research Triangle Park headquarters in North Carolina.


Bill Harnett is the Director of the Air Permitting Division of the U.S. EPA. He says the
meetings will give the public a chance to ask questions and make comments about
changes to New Source Review.


“It gives them more of a direct feed into the agency and the process, and it’s
something we always do on our rules is offer this kind of opportunity. And on
major rules like the one we’re doing, we always offer it in multiple places in the
country.”


Harnett says he expects a good turn-out, and the hearings could last all day.


After all public comments have been received, the EPA will review them and
decide whether to make the proposed changes.

Manmade Dead Zone to Block Asian Carp?

The Asian Carp is a huge fish that’s native to China. It was brought over from China and during the Great Flood of 1993 escaped from farm ponds and got into the Mississippi River. The Asian Carp competes with native fish and destroys their habitat. Researchers worry that if the Asian Carp gets into the Great Lakes, it could damage the lakes’ ecosystems. Some scientists believe that the threat of this invasive fish to the Great Lakes fishing industry is great enough to take drastic measures. One proposal would kill part of a river that connects the Mississippi River System to the Great Lakes. The Great Lakes Radio Consortium’s Annie MacDowell reports:

The Asian Carp is a huge fish that’s native to China. It was brought over from China and
during the Great Flood of 1993 escaped from farm ponds and got into the Mississippi
River. The Asian Carp competes with native fish and destroys their habitat. Researchers
worry that if the Asian Carp gets into the Great Lakes, it could damage the lakes’
ecosystems. Some scientists believe that the threat of this invasive fish to the Great
Lakes fishing industry is great enough to take drastic measures. One proposal would kill
part of a river that connects the Mississippi River System to the Great Lakes. The Great
Lakes Radio Consortium’s Annie MacDowell reports:


Since late in the 19th century until now, Chicagoans have spent billions of dollars to
clean up their water. Untreated sewage used to flow into the Chicago River and was
carried into Lake Michigan, where the city got its drinking water.


In the summer of 1885, 12 percent of the population of Chicago died of cholera and
other diseases because of fouled water.


Phil Moy is with the Wisconsin Sea Grant. He says before modern-day sewage treatment
plants, the river was a cesspool.


“You go back far enough, like before there was really even much more than primary
treatment… you had cattle carcasses and all sorts of nasty things floating and actually in
the river itself.”


More than a century ago, city planners decided to reverse the flow of the Chicago River,
to protect people’s health. This involved digging a larger and deeper canal that connected
the Mississippi River system to the Great Lakes. From then on, sewage dumped in the
Chicago River flowed downstream instead of into the lake. Chicagoans’ water supply
was no longer tainted, but the project opened up a way for fish and other species to travel
between the rivers and the Great Lakes. So Chicago’s efforts to clean up the sewage back
then, has caused unintended consequences a century later.


Now scientists are trying to find ways to stop exotic species that have invaded the
Mississippi from getting into the Great Lakes and exotic species that have invaded the
Great Lakes from getting into the Mississippi. Ships and barges use the canal to transport
goods, so putting up a physical barrier wouldn’t work. For now, the government has
spent more than a million dollars on an electric barrier that repels the fish, but they need a
second electric barrier for extra protection. However, more money from the government
to build the second barrier has been slow in coming.


So in the interim, some experts have come up with an idea… a temporary solution that
flies in the face of the Clean Water Act. They want to pollute the river again.


Jerry Rasmussen is with the Mississippi Inter-State Cooperative Resource Association.
The group tries to coordinate states’ efforts to protect the river system. Rasmussen says
creating a dead zone could be done easily and at low cost.


“Probably the least expensive thing to do in this situation would be shutting down some
of the treatments. It would be a cost effective measure, certainly in the interim.”


Rasmussen says the first step would be to shut off the aerators.


(natural sound)


South of Chicago, along part of the canal that connects the Chicago River to the
Mississippi River system, an inoperative aerator sits alongside the water. It’s not needed
in the wintertime, because there’s enough oxygen in the water during the cold months.
During the summertime, the aerators are turned on to help keep the river healthy. But
Irwin Polls of the Metropolitan Water Reclamation District says shutting off the aerators
alone during the summer would not reduce the oxygen level enough to be lethal to the
fish.


“Keep in mind, in the early fifties and in the nineteen-sixties, before supplemental
aeration, before the treatment plants were upgraded, the primary fish species in these
waterways were carp and goldfish which could survive at lower oxygen levels than we
have today.”


So if common carp could survive the lower oxygen levels, maybe Asian Carp could, too.
If shutting off the aerators isn’t enough to degrade the river’s water quality, things could
get messy.


Jerry Rasmussen says releasing more sewage waste into the river by omitting the final
stage of waste treatment could be enough to create the dead zone. If not, Rasmussen says
chemicals would need to be added to make the water more toxic. Irwin Polls says this is
a bad idea.


“The kind of chemicals they’re talking about are hazardous. Over one and a half billion
gallons of treated sewage enters this system every day so you’d have to kind of add
enough material to dilute the system that you have in there so we’re talking about large
volumes, continuously, of toxic compounds. So it would be in violation of the law, the
federal laws, as far as introducing toxic compounds and the cost I think would be
astronomical, because the volume of water is tremendous.”


Breaking federal law is the major obstacle to implementing the dead zone plan. To
violate the Clean Water Act, scientists would have to get the support of the Mayor of
Chicago, the Illinois Governor, the U.S. Environmental Protection Agency, and
ultimately the President.


But some scientists believe they’ve got to do something now to stop the Asian Carp.
They’re worried the carp might get into Lake Michigan while they wait to get enough
government money to make repairs on the existing electric barrier, and to buy and install
the second. They hope to have the second line of defense in place in a year. A meeting
with government leaders and experts on invasive species has been scheduled for
sometime in May. That’s when the plan’s supporters will try to convince policy-makers
to kill part of the river.

Carbon Dioxide Injection to Reduce Pollution?

Scientists are talking about a new way to address global warming. Their idea is to take carbon dioxide from coal-burning power plants and inject it deep into the earth. The Great Lakes Radio Consortium’s Annie MacDowell explains:

Scientists are talking about a new way to address global warming. Their idea is to take carbon
dioxide from coal-burning power plants and inject it deep into the earth. The Great Lakes Radio
Consortium’s Annie Macdowell explains:


It’s called carbon sequestration. The idea is to use a chemical process to remove carbon dioxide
from power plant emissions and pressurize it into a liquid form. The liquid would then be injected
into saline aquifers up to ten thousand feet below the ground.


The government wants to create 4 to 10 regional partnerships to study the possibility of carbon
sequestration. One of the potential sites is in the Illinois Basin. The basin extends throughout three
quarters of Illinois, into Western Indiana and Western Kentucky.


Robert Finley is the director of the Center for Energy and Earth Resources at the Illinois State
Geological Survey. He says carbon sequestration could be a good transition for the country as it
moves away from using fossil fuels.


“It would allow us to use coal in a more environmentally responsible way while we look toward the
future with additional use of renewables and ultimately, perhaps, going to a hydrogen economy.”


Finley says at this point, sequestration doesn’t work with other pollutants found in power plant
emissions, such as sulfur dioxide, nitrogen oxide, and mercury.

Ijc Hears Concerns Over Task Force Report

An international group that monitors the health of the Great Lakes is working on a report that
they hope will help policymakers manage the waters in the basin. The Great Lakes Radio
Consortium’s Annie MacDowell reports on a public hearing that took place in Chicago:


Concerned groups responded to a report that came out two weeks ago by the International Water
Uses Review Task Force. The International Joint Commission appointed the task force to
provide an update on developments that have taken place in the basin since the Commission’s
2000 report.


Noah Hall is from the National Wildlife Federation’s Great Lakes Office. He says he’s
concerned the task force’s report does not emphasize how serious threats to the Great Lakes have
become.


“The report could mislead the public or interested policy makers and lull policy makers into
complacency in terms of the need and the urgency for basin-wide protection for the Great Lakes,
particularly for ground water.”


Hall said ground water depletion is causing problems in the communities around the Great Lakes
Basin. Other criticisms of the report were its failure to look toward the future on issues like
climate change and water diversion. The U. S. Chairman of the IJC says the Commission will
study all the public’s comments at a retreat and write their official report within two to three
months.

Water Filter to Reduce Beach Closings?

Beaches throughout the Great Lakes have long been plagued by bacteria that can make people
sick. For the first time in the region, researchers will test a filter designed to guard a swimming
beach from hazardous bacteria. The Great Lakes Radio Consortium’s Annie MacDowell reports:


Next April, the Chicago Park District plans to install and test an eighteen-hundred foot-long
floating filter system. A similar technology was used to protect fish hatcheries during the 1989
Exxon Valdez oil spill. And studies show the system has been successful in decreasing bacteria
levels at New York beaches.


Jim Miner is the Executive Vice-President of Gunderboom Incorperated, the company that makes
the filter. He says the filter will surround the beach like an underwater curtain:


“What is underwater, the fabric curtain, will not be seen by the swimmer and it is a non-intrusive,
fabric-filtered barrier that goes from the surface to the bottom and it’s anchored there and
protected so that only filtered water can get into the swimming area.”


The technology could reduce swimming bans at city beaches.

Killing River to Stall Spread of Invasives?

Biologists are trying to prevent invasive species such as the Asian carp from traveling between
the Great Lakes and the Mississippi river basin. The latest plan proposed by some scientists is to
remove all the oxygen from a section of the Chicago river. The Great Lakes Radio Consortium’s
Annie Macdowell has more:


Scientists say killing part of the river would create a barrier no fish could swim through and live.
Removing the oxygen is against the Clean Water Act, but biologists think it might be worth it.


Jerry Rasmussen is a river biologist with the U.S. Fish and Wildlife Service. He says the
potential economic and ecological disaster from the invasive species justifies creating this dead
zone.


“The real problem has been reluctance of everyone, including myself, to take a measure like this
because of the implications of it and the precedents it sets, but the concern is significant enough
with these Asian Carp that a significant problem may require significant measures to stop it.”


Rasmussen says killing a section of the river buys engineers time to work on a long-term solution
to the invasives problem, such as building a second electric barrier. He says the river would be
shut down for a minimum of two years and then re-oxygenated so that living things could return.

New Air Regs to Allow More Pollution?

According to data from the EPA, air pollution from older, dirtier power plants leads to thousands of premature deaths each year.

According to EPA estimates, air pollution from older, dirtier power plants leads to thousands of
premature deaths each year. Now, environmental watchdog groups worry that recent changes to
Clean Air Act regulations will allow these aging power plants to continue to pollute. The Great
Lakes Radio Consortium’s Annie MacDowell reports:


Most of the coal-burning power plants in the Midwest are more than 25 years old.


Under EPA regulations, called New Source Review, these grandfathered power plants would
have to install modern pollution controls if they undergo any major upgrades.


Recently, the EPA relaxed standards on New Source Review regulations.


The EPA says the changes will cut through a lot of red tape and will provide flexibility for power
plants to improve and modernize their operations.


But environmentalists say the Bush Administration is catering to big business.


Howard, Lerner is Executive Director of the Environmental Law and Policy Center. He says the
changes to New Source Review regulations will let old power plants stay dirty.


“This is a break that’s being given by the Bush Administration for the coal industry, for the
utilities, the oil refineries and it comes down to a classic case of what’s good here for some of the
highly-polluting power plants is bad for the public when it comes to clean air and good health.”


Meanwhile, a group of Northeastern states that say they receive air pollution from Midwest
power plants plans to file suit challenging the changes.

Managing Unwelcome Geese

Transcript

Growing numbers of Canada Geese are taking up residence in the Midwest instead of
migrating in the spring and fall. As the Great Lakes Radio Consortium’s Annie
Macdowell reports – government officials and environmental groups are coming up with
creative ways to control the growing population:


Canada geese are becoming a familiar sight on front lawns and in retention ponds across
the Midwest. Goose excrement is a nuisance to residents and bacteria in their feces can
make people sick. Vid Rapsys owns an Illinois franchise of the “Geese Police.” This
special force uses border collies to gather and frighten geese away from private property
without hurting them.


“Tell the dog to come by while it’s in the water. It’s going to swim in a clockwise motion
around the geese in the water. The geese become very unnerved when animals come in
the water after them. Especially animals that looked like they were stalking them on land
and now there’s someone after them in water.”


But Rapsys adds the Border collies don’t offer a permanent solution. Usually the birds
just fly a couple of miles away and settle in someone else’s lawn or pond. More
permanent options involve shaking goose eggs or covering them with vegetable
oil, which stops the growth of the embryo. But aside from killing geese during hunting
season, people are not allowed to harm a Canada goose. They’re protected by a law
written in the early 1900s.

Eliminating Mercury in Sewage Treatment

A city along Lake Michigan is fighting the construction of a waste-treatment plant. The town filed a lawsuit against the local waste-treatment company that wants to dry and burn sludge from half the surrounding county. City officials say they don’t want an eye sore on their lake front and environmentalists are worried about mercury getting into the lake.

A city along Lake Michigan is fighting the construction of a waste-treatment plant. The
town filed a lawsuit against the local waste-treatment company that wants to dry and burn
sludge from half the surrounding county. City officials say they don’t want an eye sore on
their lake front and environmentalists are worried about mercury getting into the lake.
But the sanitary district says it has a system that will virtually eliminate emissions. As
the Great Lakes Radio Consortium’s Annie Macdowell reports, environmentalists say
that’s not enough:


After rolling out of bed in the morning, what’s the first thing you do? Do you use the
toilet? Take a shower? Brush your teeth? Probably one or all of the above. And what
happens to that unwanted dirty water? It just vanishes, right? Flushes into oblivion?
Disappears down the drain? Wrong. All that scummy sludge heads straight for your
local waste water treatment plant.


The North Shore Sanitary District along Lake Michigan in northern Illinois receives 187
tons of waste water a day. That adds up to 20 trillion gallons of the stuff a year. And in
among all that waste there are 26 different toxic metals. At this point, North Shore is
trucking the toxic sludge to landfills and dumping it. Brian Jensen is the general manager
of North Shore. He says toxic chemicals aren’t necessarily safe in a landfill because a
landfill liner can leak.


“If in fact, that liner were to leak, and there’s been a history around our country and in
Europe that these liners do leak, when that happens, the environmental liability is
extremely significant.”


With these worries in mind, a couple of years ago Jensen started looking around for a
new way to dispose of the sludge. He says a process called “sludge-drying” was the best
option.


Here’s how the system works: the sludge is pumped into a dryer where most of the water
is sucked out. Then the dried sludge is burned as fuel for the next part of the process –
the melter. The melter burns up the organic part of the sludge at 3000 degrees. That’s
hot enough to melt heavy metals. So after everything else is burned away, what remains
are the toxic metals locked up in a glass matrix that looks a lot like lava. It’s called glass
aggregate. It can be used in concrete where it’s sealed and can no longer pollute water or
soil.


The only toxic metal that doesn’t go into the glass matrix meltdown is mercury. That’s
because in the hot melter, mercury becomes a vapor. Over the course of the year, north
shore gets about 33 pounds of mercury – a third of it comes from fillings in people’s
teeth. The rest is from industry and commercial sources.


People in the area and environmentalists, object to the idea of the plant emitting all that
mercury into the air. That’s because it could further contaminate Lake Michigan which
already is contaminated by mercury from coal-burning power plants. Cameron Davis is
the head of the Lake Michigan Federation. He says mercury is a dangerous neurotoxin.


“You know the MadHatter in Alice in Wonderland? That character was developed
because in the old days, people who made hats actually used mercury in the hat
manufacturing process, and that mercury being around it in the manufacturing of hats,
would cause people, literally, to go insane, to go crazy.”

Davis says Lake Michigan already has a fish advisory because mercury has contaminated
the water so badly. If people eat the fish, especially expectant mothers and children,
there could be serious health effects. Mothers could pass mercury poisoning onto their
infants. Children’s bodies are especially susceptible because they’re developing so fast.
Davis says anyone who cares about the environment is against the construction of any
new source of mercury emissions.


But Brian Jensen says the North Shore sludge incinerator will fix that problem too. The
plans include a filtration system, to catch mercury in the vapor state. The air travels
through carbon canisters and the mercury particles cling to the carbon. The canisters last
for up to 5 years and then the mercury is recycled and reused. The result is something
less than two pounds of mercury emissions a year. Jensen says that’s such a small
amount that today’s scientific instruments can’t detect it in the normal emissions each day.
They’ve tried. And in the end, Jensen says it could very well be that the new North Shore
Plant will emit no mercury at all.


But Cameron Davis says any uncertainty is unacceptable.


“We do want to encourage different ways to be able to get to zero and if we are in fact
getting to zero, then we’ve got a different game here, and that’s important, but we are
talking about zero.”


But Davis doesn’t have any better ideas for getting rid of the sludge. He says North
Shore should continue landfilling for now.


Michael Murray with the National Wildlife Federation’s Great Lakes Office says there is
a better alternative. It’s a process called land application. That’s when sludge is used as
fertilizer for crops.


“There’s a study published on work in France recently where they looked at number of
different options for sewage sludge treatment and they found that land application in
general had the lowest environmental cost, in other words it was the best environmental
option.”


Murray says companies must have a really good pre-treatment program if they’re going
to use land application. That means capping levels of toxic metals before they get into
the sludge.


Brian Jensen at North Shore says he looked into land application and saw too many
problems. He says North Shore already has an award-winning pre-treatment program,
but they still get too many metals to land apply. And he’s heard about problems like e-coli bacteria growths from the fecal matter in the sludge. Beyond that, he says they just
have too much sludge and not enough land to fertilize.


Jensen says he’s confident the judge will not let the lawsuit stop north shore sanitary
district from building the plant. It already has the permits from the Illinois Environmental
Protection Agency. He’s amazed that people are giving north shore such a hard time,
when right next door to where they want to build the waste treatment plant, a coal-burning incinerator emits up to 450 pounds of mercury a year.


“The North Shore Sanitary District is truly people that are concerned about the
environment. And this process, even though it probably, it does, in fact, cost a little more
to own and operate than a landfill, the environmental gains, I’m saying the environmental
gains, not losses, are significantly greater than any other sludge disposal method.”


Jensen says environmentalists should be the first to recognize when a waste water
treatment plant is doing the very best job that’s possible with the most recent technology
available instead of criticizing the effort.
