It’s estimated, every year, somewhere
between seven and eleven-million tons
of old asphalt shingles end up in landfills.
Some states are short on landfill space.
Lester Graham reports, they’re now
encouraging grinding up and recycling
the old shingles:

Two-thirds of American homes have asphalt shingle roofs. They last twelve to twenty years before they need to be replaced.

Since most of the material in asphalt shingles is the same stuff used in asphalt pavement, that’s where they’re going.

(sound of machinery)

New businesses are popping up across the nation that take the shingles.

Chris Edwards is co-owner of Ideal Recycling in Southfield, Michigan. He says roofers can dump old shingles at his place cheaper than taking it to the landfill.

“And then they can also sell it to their customers that they are recycling and it’s green. So it does help the contractors quite a bit.”

Several states are studying how the material holds up for asphalt roads, but for now most of the singles are mixed in asphalt used for parking lots.

When most people put a new roof on
their home they usually use standard asphalt
or tile roofing. But other people are going
for something more natural. They’re planting
grass and flowers on their houses. Joyce
Kryszak talked with one builder in
Western New York who planted a green roof on
his garage to show his neighbors how it works:

About 90% of all residential roofs are made out of manufactured
asphalt.

But builder David Lanfear knows that nothing tops mother nature.
He makes roofs out of gardens.

Lanfear recently ‘installed’ one on his own garage roof, so his
neighbors could see the benefits. There are beautiful flowering
plants visible over the edge of the flat roof. Lanfear says they’ve got
the whole birds and bees thing going on.

“We’ve noticed a big increase in insects, butterflies, birds all
sorts of new birds that I haven’t ever seen. They’re up there
eating something. Bugs? But its kind of nice to sit on the deck
and watch this nature in the city thing,” said Lanfear.

But the living roof isn’t a novelty. Lanfear says the roofs are more
eco-friendly. He says a living roof provides a whole cascade of
environmental benefits.

“Especially in a downtown when you get a hard rainfall the water
washes off all at once. There’s nothing to absorb it. If you had
a roof like this it absorbs the water and let’s it off slowly. So, it
not only slows the runoff, it cools the water and it starts to filter
the water. It filters some of the atmospheric crud out.
Otherwise, you get super heated water rushing off into the storm
sewer, and then out into the river or the lake and effecting the
environment there,” said Lanfear.

Once his neighbors understood the concept, they stopped thinking
Lanfear was crazy. A few even offered to give him a hand planting
his roof.

First the roof was reinforced with used lumber. Next are the
waterproof barriers – a rubber membrane, a root barrier made out of
old billboards and some old carpeting. Finally, recycled, crushed
concrete is shoveled on to be used as soil for the plants to grow in.

It’s all sustainable. And the native plants require very little water or
maintenance.

Neighbor Deborah Bach loves to garden. So, she was happy to
pitch in. Bach says the concrete soil needs to be doctored to enrich
it. But they have a reuse idea for that too.

“My son works at Starbucks and they give out free grounds for
gardens. So, we’re going to try doing that to try to balance this
out. You know, using recycled materials and things that have
already been used,” said Bach.

Another neighbor stopped by to help. Alex Sowyrda is a high school
technology teacher who’s interested in the science of green roofs.
He plans to share what he learns with his students.

“I try to bring it into my curriculum at school and, hopefully, the
kids graduating high school now take this knowledge with them
and are able to make responsible choices in the way they build
and the way they design in the future,” said Sowyrda.

The living roof builder David Lanfear says it’s a concept that can grow
on anyone. Even people who grew up with more traditional roofs. He
says to start small – with a garage roof – or maybe even smaller.

“We all have little expanses of roof in front of windows. And in
the summer you might notice that when the window is open the
hot air blows in, a lot of that heat comes from that little bit of
roof. If we could just put sections one square yard of living roof
outside of our windows on the porch roof, that would make a
drastic difference in cooling our house – simple,” said Lanfear.

And pretty cheap. Lanfear says the cost of materials is about the
same as an asphalt roof. But he says there’s savings in the long run
because the green roof can last three times as long.

And he says it’s a whole lot nicer to look at.

Making Solar Power Mainstream

Solar panel technology has been around for decades…but not many
people have panels on their roofs. Solar energy is the ultimate clean
power source, but it’s also expensive and that’s kept most people away.
But regulators in one state are hoping to change that. The state’s Public
Utilities Commission recently approved a 3-billion dollar fund to give
homeowners and businesses hefty rebates if they install solar panels. It’s
the first program of its kind and size in the nation. The Great Lakes
Radio Consortium’s Tamara Keith reports:


A little over a year ago, Chuck Wingo and his wife Pam moved into a
new house in an innovative housing development. Their house, like all
the others in the neighborhood, is equipped with bank solar panels, built
right into the roof like shingles.


“These are the 2 meters that are on the house. It’s simple. One uses for
our usage, what we use, and the other one is from the solar panels, what we
produce.”


Chuck says sometimes he walks to the side of his California house and
just watches the solar meter spin.


“We check it all the time, what’s even better is checking the bills. The
bills are great, we paid 16-dollars for our usage in August, the hottest
month in Sacramento. So, it’s kind of cool.”


The Wingo’s weren’t big environmentalists before moving into this
house, but Pam says when she heard about this development, something
clicked.


“The idea just sounded, if you’re going to move, do it right at least. Do
something pro-active about where you’re going to be living and spending
your money. It’s really good for everybody, for the country. We all
should be living like this so we’re not wasting out energy.”


And many more Californians will be living that way, if the California
Solar Initiative lives up to its promise. State energy regulators approved
the initiative, which will add a small fee to utility bills in order to create a
3-billion dollar fund. That fund is designed to make solar panels more
affordable.


It starts by offering rebates to consumers who buy them. Bernadette Del
Chiaro – a clean energy advocate with Environment California – says
once those panels get cheaper, the marketplace goes to work…


“The problem with solar power today is its cost. Most of us can’t afford
an extra 20-thousand dollars to equip our home with solar panels, and
what we’re doing in California is saying, we’re going to get the cost of
solar power down. By growing the market 30 fold in the next 10 years,
we’re going to be able to cut the cost of solar panels in half.”


Last year, Governor Arnold Schwarzenegger tried to get the California
legislature to approve something similar. That plan got bogged down in
state politics … so he took it to the Public Utilities Commission. While
the commission can raise the money, there are some parts of this
revamped solar program that have to be legislated.


Democratic State Senator Kevin Murray has worked with the Republican
Governor on solar power issues. He says he plans to introduce a new bill
that would require solar panels be included as an option on all new
homes built in the state.


“Rather than some specialized left-wing alternative kind of thing, we want it to
be in the mainstream, so that when you go in to buy a new home, you
pick your tile and you pick your carpet and you pick your solar system.
So, that would have to be done legislatively and the other thing that would
have to be done legislatively is raise the net metering cap so that if you’re
selling energy back to the grid, you can get compensated for it.”


The new program would also target businesses, even farms. Public
Utilities Commissioner Dian Grueneich says she hopes this doesn’t stop
with California.


“I’m very, very excited. This is the largest program in the country
and I’m hoping that other states will look at this program as well, so that
it’s not just something in California but helping other states.”


And if the solar power initiative is a success in California, backers say
it’s good news for consumers all over the country. Much like the hybrid
car, made cool by Hollywood celebrities… California leaders hope they
can make solar trendy and more affordable for everyone.

Crafting a House From Scrap Lumber

One man and a few of his friends are using some old-fashioned methods and some cutting edge techniques to build an environmentally friendly house. The builders are also using a lot of material that other people would throw away. The Great Lakes Radio Consortium’s Chris McCarus reports:

One man and a few of his friends are using some old-fashioned methods
and some cutting edge techniques to build an environmentally-friendly house.
The builders are also using a lot of material that other people would throw
away. The Great Lakes Radio Consortium’s Chris McCarus reports:


Four men are raising a timber frame house on an old farm
in central Michigan. Several feet up in the air, they’re piecing together
some beams, 12 feet long and 12 inches thick with some help from a small
crane.


(Sound of engine)


“Cable it! Cable it! Cable it? Yes!”


(Sound of tool dropping)


The framing is like assembling giant Lincoln Log toys. Neighbor Nick
Van Frankenhuyzen is holding a rope attached to some beams.


“Look at that. Look at how far that is extended. We lifted one of
those beams yesterday by hand and they’re not light. Now this wall has to
come back. This has to pop out again to make that one fit and I don’t
know how that’s gonna happen.”


Facing these kinds of challenges is what people in the green building
movement seem to relish. Kelvin Potter owns this farm. He’s using materials
that most builders overlook.


Potter: “Yeah we saved all these timbers, developers were burning all these.
So. These were all going up in smoke. And some of these logs came off my
neighbor’s property. They had died and were standing. We dragged ’em over here. He planted them. He’s
standing right there.”


Van Frankenhuyzen: “Yeah we’re standing on them. And then Kelvin
said I sure could use them. Because they’re the right size. Go get ’em. So he did. And here they are. Can’t believe it. Much better than firewood.”


Kelvin Potter’s home is one example of a growing trend in green building.
The U.S. Green Building Council includes 4000 member organizations. It’s
created standards for protecting the environment. The standards include
reusing material when it’s possible, using solar and wind energy, renewable
resources, and non-traditional materials. Sometimes from surprising
places.


(Sound of truck)


A city truck dumps wood chips onto a municipal lot. On other days it
dumps logs like sugar maple, oak and pine. The trees came from routine
maintenance of parks, cemeteries and streets.
Kelvin Potter is also here, checking for any fresh deliveries. While other
guys come here to cut the logs with chainsaws for firewood, Potter says he
makes better use of it as flooring or trim. Even saw mills don’t take advantage of this kind of wood. That’s because
trees cut down in backyards often mean trouble for the mills.


“Sawmills typically aren’t interested in this material because there is
hardware, nuts, bolts, nails, clothes lines, all sorts of different things
people have pounded into them by their houses. ”


Potter says sawmills use big machines with expensive blades that get
destroyed. So THEY throw the logs away. Potter instead keeps the logs and
throws away his blades. He uses cheap ones, making it worth the risk.
When it’s finished, Kelvin Potter will have an environmentally friendly
house, even if it doesn’t meet all the criteria to be certified as a “green
building.”


Maggie Fields works for the Michigan Department of Environmental Quality.
She says there are many ways to build green. Anything that helps the
environment is a big improvement on the status quo.


“Every material that we reuse is a material that doesn’t have to be cut
from the woods, if that’s where it’s coming from, or remanufactured. And that means that the pollution that’s associated with that material getting
to that use state isn’t having to be created. So, it doesn’t matter if they
get the green seal. If they’re taking steps along that that’s great.”


(Sound of climbing ladder)


Kelvin Potter is climbing a ladder to the belfry of his new house. He
shows off his shiny steel roof, the kind now covering barns. He compares it
to asphalt shingles.


“It lasts 100 years versus 15, 20 years. We actually fill a lot of landfills with shingles. They don’t compress. They don’t decompose. Steel will
go right back into making more roofing or cars or what not. It’s a win-win
situation. It’s a lot cheaper all around and I can’t see why it’s not a lot
more popular.”


The point Potter and other green builders are trying to make is, good
building material isn’t just the stuff marketed at lumberyards. They say, “Look around. You might be surprised what you can use.”
