Some big corporations and some small businesses are taking a serious look at their impact on the environment. Some are using a science-based framework called the Natural Step to try to operate more sustainably. Stephanie Hemphill visited one, and has this report:

The Duluth Grill is a family restaurant. Tom Hanson is the owner here. He says things started changing for the restaurant when he decided he should be offering healthier foods. He says too many of us are gaining too much weight. So he changed the menu, and now he says people can still go out and have a good time without it all going to their waist.

“Whether it’s French fries or fruit or healthy home-made soups, people can be socially engaged eating out but you’re not necessarily sacrificing your eating habits or eating styles.”

His menu offers healthy ethnic meals, gluten-free foods, and teas that claim health benefits.

Once Hanson started thinking about the health and well-being of his customers, he started thinking about the other impacts of his business. He joined a group of about a dozen businesses recruited by a local non-profit to try out the Natural Step approach to sustainability. The Natural Step was developed in Sweden, but it’s being used all over the world.

Restaurant staffers attended training sessions on how ecosystems work, and on what it means to be sustainable.

Manager Jeff Petcoff shows off the new LED lights in the restaurant.


“They produce 12 watts of energy versus 320 watts from the regular light bulbs that we were using prior to this. It’s a little more intimate with dining at night, but we’ve had a positive reaction to that as well.”

The Natural Step program encourages reducing the use of fossil fuels and other resources that have to be mined from the earth. And it calls for not throwing as much garbage into the earth.


In the kitchen, workers separate the trash. There’s a bin for recyclables, one for trash, and one for food scraps. Petcoff says the food waste goes for compost.

“We’ve just made it very easy for our staff to be able to compost and recycle with the bins all over the restaurant.”

The Duluth Grill has reduced its weekly trash pickup, and saved a bunch of money in the process. Owner Tom Hanson says saving money is nice, but part of the Natural Step program calls for not degrading the earth, like by building landfills.

“We don’t live next door to landfill but somebody does, and once you become aware of it, I think, it becomes more compelling to do it.”

And the restaurant encourages its customers to get involved in helping each other. Next to the front door there’s a bin where people can dump their old magazines. A local youth center is recycling them to raise money.

And there’s a bookshelf where people can leave children’s books; it’s part of a community-wide literacy campaign.

One Natural Step principle is about people: a sustainable business operator makes sure the people who work there, and even the suppliers and customers, anyone who has contact with the business, can meet their needs without a big struggle.

Tom Hanson dreams of offering health coverage to all his staff — and maybe someday even child care.

“You could easily consider day care for your staff as being an expense that no small operator could afford. But when you make change little by little, that step could very well enter into our values, and once it becomes one of our values it becomes affordable.”

Many businesses are making these kinds of changes and you might not even be aware of it. But Tom Hanson would say if you’re not sure, ask. You might prompt someone else to do better.

She recently visited a church that’s

thinking more about its impact on the

environment:

The folks at Gloria Dei Lutheran Church in Duluth Minnesota are studying
more than their Bible these days. They’ve been learning about how the
ideas in the Natural Step can make their church operate more sustainably.

One Saturday in the church basement, about a dozen people from churches
around the region are talking about what sustainability means.

Judy
Isaacson is from a small church in the country.

“It’s a growing understanding that we as individuals have to be responsible
for what we do, and then I think a big part is helping people understand
it’s not that difficult to live up to what our values are and what we see
happening.”

Isaacson says it’s easier to talk about the practical ways to be
sustainable than to expound on the theory. She’s been learning how to
encourage everyone in her church to get involved in making small changes.
Like using less electricity.

“We’re the newbies at our church; we’ve only been in the church six years.
And by having someone who’s been there forever change the light bulbs, it
was very easy because she had credibility within the congregation.”

For many Christians, the Natural Step fits right in with what they call
“creation care.” For them it means taking care of what God created.

The Natural Step publishes its principles on the internet, along with
inspiring examples of how it’s working in various places around the world.

In Duluth, a non-profit group brought the Natural Step to town. Experts
from Canada gave several day-long training sessions to about a dozen
businesses and organizations that committed to a year-long effort to put
the ideas to work.

Sue Anderson took part in the training. At the Saturday workshop in the
church basement, she mentions some of the things the church has done.

“The use of glasses and cups, reuseable items. We kind of got that going
through a lot of different committees, you know our neighborhood breakfast
and things like that.”

No more throw-away styrofoam cups. That fits in with one of the principles
of the Natural Step: don’t wreck the earth by building more landfills than
you absolutely have to.

Another principle is: use less fossil fuel, and other resources that have
to be mined from the earth.

When they replaced the roof at Gloria Dei, they added a lot of insulation.

David Carlson is pastor of Gloria Dei. This year he used Lent as a chance
to educate the congregation. He asked people to go on a “carbon diet” for
Lent.

“There’s usually a confession and forgiveness of not only the brokenness
that we have with God and between us and other people, but also the
separation that we have with creation. And this is one way that we can
participate in the healing of God’s creation.”

Carlson says a lot of church members are taking on projects. One man is
promoting the idea of ride-sharing to church.

“He is offering a free pillow-pack of fair trade coffee to anyone who comes
to him during coffee hour and says that they car-pooled that day. It’s
trying to remove barriers for people that may be in the way of taking
further steps. And they may be small. But they may make a difference.”

The biggest difference this group might make is offering their experience
to others. The non-profit group behind the Natural Step in Duluth is
documenting their progress and hoping others will join in.

A Spark in Your Step

When you think about alternative energy
sources, you probably don’t include people on your
list. But Ann Murray reports that scientists are
tapping into bionic people power:

Today, we really do have bionic technology.

(Opening of the “Six Million Dollar Man”) “Gentleman, we can rebuild him. We have the technology.”

Okay, maybe not to turn you into
the Six Million Dollar Man. But how about a mobile power plant?

Let’s start with the back story.

About 15 years ago, a couple of young
scientists, Doug Weber and Max Donelan, worked together. Donelan wrote
his grad school dissertation on the energy people create when they walk.
He asked Weber, now a biomedical engineer at the University of
Pittsburgh, to run with his idea.

“He approached me with the idea of building a wearable device that could actually harvest
that energy. And not only generate electricity but potentially make it easier
to walk.”

Weber and Donelan put together a rough prototype in his garage. A lab
tested version of their early demo was just published in the journal Science.
The bionic gizmo looks pretty much like a knee brace with a power pack
attached. Weber calls up a video on YouTube to show me how it works. On
the screen, a guy with a brace on each leg is walking on a treadmill.

“With each step he takes on the treadmill power is generated when the
knee is swinging in extension. It’s during that extension phase that we turn
on the generator and as the traces below the video show, generate large
peaks in power.”

Those peaks in power show up as the hamstring muscle “brakes” to keep
the leg from going too far forward. That’s when the bionic brace kicks in. It
grabs that potentially wasted energy and turns it into electricity.

The brace can crank up to 20 watts with each step. That means ten
minutes of walking can power a laptop for a half hour. No other lightweight
people-powered generator can top that.

Yad Garcha’s betting that people
will be intrigued. He’s the CEO of Bionic Power, a company formed to
market the brace. With some product tweaking, he envisions a world of
alternative energy possibilities. Especially for people who have to depend
on batteries or don’t have much access to electricity. His list includes
millions of people in developing countries, amputees, and soldiers.

“It is a green product primarily for the military because of the number of
batteries that they throw away.”

Garcha says, for example, Canadian soldiers carry up to 20 pounds of
disposable batteries.

“And these throw-away batteries cost a lot of money for them to get them into the
theatre or wherever they’re doing their fighting.”

Garcha’s already been talking to Canadian military reps about field tests.
But the brace probably won’t be ready for another year or two. The
prototype still needs to be quieter, lighter, and more efficient before it makes
its way into the hands – or rather, the legs – of consumers. Better move over
Steve Austin!
