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:

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.”

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.
