Slimy, hungry invaders are moving through
the waters off the Northwest coast of the US.
They’re called invasive tunicates –
or sea squirts. And they’re the same invasive
species that devastated shellfish farms on Canada’s
east coast. If invasive tunicates aren’t controlled,
you could see a lot of seafood options disappear
from markets and menus. Ann Dornfeld has the story:

It’s a peaceful spring morning at this suburban marina. But beneath the water’s surface, a hunt is
underway.

(water sounds)

Professional divers – like Jesse Schultz with the Washington Department of Fish and Wildlife – are
combing the docks for invasive tunicates. They don’t have to look far.

“That’s one of the tunicates right there – that’s the guy right there.”

Schultz surfaces holding a jelly-like tube. Sea squirts compete with everything from clams to tube
worms for the plankton they all eat. The sea squirts usually win, because they don’t have native
predators. Three species came here from Asia, probably on boat hulls. Today, divers are cleaning
the hulls of local boats to keep the sea squirts from spreading.

Allen Pleus manages invasive species for the state.

“The whole intent right now is a containment action. We want to prevent any of these boats
from leaving this harbor with the tunicates attached to their bottom, going to another
harbor, and infesting that harbor or marina.”

When invasive tunicates get to a new harbor, they quickly become the dominant species. In the
warm part of the year, they spawn every 24 hours. And along with hogging the food supply, one
species of sea squirts forms a slimy mat that smothers mussels and other shellfish.

Pleus says if tunicates get out of hand, they could make a big impact on the seafood industry.

“It can definitely affect especially shellfishing in this area. Puget Sound, Western Washington is one of
the largest producers of shellfish in the nation. It could also affect other populations of
food fish, including salmon, by taking out a lot of the nutrients that juvenile salmon feed
on.”

Nova Scotia learned that lesson the hard way. Pleus says in Eastern Canada, entire shellfish
farms were recently wiped out by invasive tunicates.

“So the rap sheet is clear. They can grow to exponential sizes, quantities and smother
aquaculture facilities. They can’t even lift up their lines it’s so heavy with these critters on
it.”

To prevent the same thing from happening here, the state workers have to move quickly – and
they have to be thorough.

“Here’s another bag, Justin!” (splashing sound)

Back in the water, diving biologist Jesse Schultz has his hands full with a boat that has apparently
been docked for seven years. Its tabs show that’s the last time it was registered.

“This guy’s getting a free boat cleaning, sort of!”

The state is trying to scrape clean every infested boat in Puget Sound before the summer boating
season. But Schultz says because the docks are still covered with invasive tunicates, they’ll grow
back on this boat if the owner doesn’t keep it clean.

“That’s the biggest thing these guys can do to keep these things from spreading is have
their boats maintained.”

The state is still figuring out the best way to clean the docks. So far biologists have cleaned only
one entirely. When they were done, they’d removed ten tons of critters.

Unfortunately, Allen Pleus says only some of those were tunicates. In order to get rid of the
invasive sea squirts, they have to employ a sort of scorched earth policy.

“That is one of the hardest parts of this is that we have to basically take everything out.”

That means the good with the bad. We sift through a bucket of the creatures scraped from the
dock. Along with plenty of invasive tunicates, there are brightly colored sea cucumbers, scallops,
mussels, rock oysters, feather duster worms and chitons – exactly the kinds of animals the state
is trying to protect. They have to destroy the habitat in order to try to save it.

If you spend a lot of time on the Internet,
you probably know about MySpace, and Facebook, and
maybe you use Wikipedia to look up things quickly.
Well a couple of guys in California are combining
social networking, web content, and citizen action
to make a green website called Creative Citizen-dot-
com. Lester Graham spoke with Scott Badnoch and Argum DerHartunian:

Scott Badnoch and Argum DerHartunian: “CreativeCitizen-dot-com is based on the idea that we need
to infuse action into people’s lives when it comes to the green movement. So, we call ourselves
the action-based green community. And it’s essentially where Wiki meets social networks. So,
we’ve taken the best of both worlds and put them together. And so, instead of trying to be a static
content provider, what we do is we open up the playing field for the entire community to be
involved.”

Lester Graham: “Now, when you’re talking about opening up to the whole community, that just
seems you’re asking for a lot of misinformation to be passed around. Who’s monitoring this to
make sure that you ensure accuracy on this thing?”

Badnoch and DerHartunian: “It’s very rare that people provide things that are absolutely incorrect.
Now, at the same time, we also have experts. And I’d also like to add that our experts really guide
the process. They show people where to go to find more information, so then more eyes are
actually looking at it, and making sure the information is actually accurate and effective in the real
world.”

Graham: “Well, even among the experts there’s an amazing amount of confusion about everything
from everyday questions like ‘paper or plastic?’, to lawn care, purchases we make – how do you
plan to get around some of those complicated issues that might depend on where you live, or other
circumstances of your locale or your lifestyle?”

Badnoch and DerHartunian : “We’re not saying we are the sort of all-knowing Gods of green, but, in
reality, we’re saying ‘hey, we don’t know’, and neither does the vast majority of people. So let’s all
contribute, and put the knowledge that we do have together, so we can actually get a more clear
understanding of what this green-thing is.”

Graham: “Your CreativeCitizen-dot-com site seems like it might just be the perfect opportunity for
some of these corporations to come in and really spin things for systems that might not be that
great. How will you compete with corporate green-washing you might see on your site?”

Badnoch and DerHartunian: “On CreativeCitizen-dot-com, we’ve created an organic R&D system,
where each creative solution is uniform in a sense, and users can come and comment on
solutions, and edit them. And companies are really putting themselves out there by saying ‘this
product or service really has this benefit or savings’. And people can say, ‘well, I’ve tried this at
home and it doesn’t have these savings’, ‘I’ve researched this product and you’re using these types
of methods to produce this and manufacture this product and it’s not good for the environment’.
Or, vise-versa, saying that this is good, and really bringing the real green products that are not
green-washed to the forefront.”

Graham: “What have you learned on CreativeCitizen-dot-com that made you a more
environmentally responsible person?”

Badnoch and DerHartunian: “Well, I’ve transformed my entire life since the process of really
understanding sustainability. But one of the main things is really understanding that efficient living
and sustainable living is not about a sacrifice. It’s about really putting in these little acts into your
daily lifestyle that really make you happier as a person, more efficient – not only in a personal
sense but in a global sense. So, one of the most simple things is recycling laundry water. I’ve built
a system in my house where I can just put the laundry water in a bin and feed it to my garden,
using waste-water that is actually more nutritious for the plants because of the minerals in the wash
cycle. I like to call it ‘optimize without sacrifice’ – that’s actually from Amory Lovins. Green is really
about optimizing your life, and making life better for you, and then the result, fortunately, is that life
is better for the whole planet.”

Graham: “Alright guys, thank-you very much.”

Badnoch and DerHartunian: “Thank you, Lester.”

A new online encyclopedia wants to give all living things on Earth their own
web sites. Even the mosquitoes and leeches. Rebecca Williams reports:


The Encyclopedia of Life is like MySpace for bugs, birds and bottom feeders.
There are bios, photos and videos of 30,000 species on the site. But
the scientists who run the site are planning pages for every species on
Earth. All 1.8 million of them.


Jesse Ausubel helps manage the encyclopedia. He wants you to be able to
pull up the site on your phone or Blackberry while you’re on a hike. Like a
field guide to find out what that funny looking bug is.


“But it’s also for scientists looking for large patterns in nature – if you want to study all plants that have purple coloring or all
animals that live at least 60 years.”


Ausubel says in a few months, they’ll launch the interactive version of the
Encyclopedia. Experts will make sure the science is accurate. But if you
want to blog about your favorite spider, there’s room for that too.

Composting in the City

  • Backyard composting isn't quite as inticing a hobby in the wintertime. (Photo by Karen Kelly)

Composting has always been a part of farm life, but a growing
number of city folks are trying it as well. The GLRC’s Karen
Kelly is one of those city dwellers, and she found if composting
isn’t convenient, it doesn’t get done:


“So we’re going to put in our banana peels, and the oatmeal that
nobody ate, and I’m going to break some of this up because apparently
it breaks down faster if it’s in smaller pieces. So right now we’ve got,
half a scone, a bowl of oatmeal, some banana peel… ”


It’s just after breakfast and my kitchen is covered with dirty dishes.
Some of the food is heading into the garbage, the rest I’m going
toss into the composter. It kind of looks like a brown garbage can
with a lid, but it takes about half my garbage and turns it back into
soil.


I started about a year ago, when I finally got a small backyard
where I live here in Ottawa, Canada’s capital city. First, I asked
my friends Connie and Dan how they do it.


“How would you guys describe your approach?”


“Laissez faire.”


“Yeah. It’s really a shame that everybody doesn’t do this because it can
be really easy. Just put it in a box and let it sit there.”


I liked the sound of that hands-off approach, but I was also
wondering what to put in and what I needed to leave out. So, I gave
George Reimer a call. He’s the city of Ottawa’s composting expert.


“ust stick with kitchen scraps, vegetables, fruit scraps…plants that
you have from the gardening season, that type of thing.”


“Okay, okay. So no animal products basically?”


“Exactly.”


Once you have a good mix of kitchen scraps, leaves and grass, the
best thing for compost is to mix it around on a regular basis. When
you add that oxygen to the microorganisms already in the garbage,
it breaks the waste down even faster.


It’s not as easy as it sounds – especially if you compost in a plastic
drum. Just imagine sticking a pitchfork into your garbage can and
trying to flip over a pile of wet dirt.


So, armed with that information, I asked George if he could take a
look at our progress after our first week of composting. He stooped
over to pull open a sliding door at the bottom of the container.


“Oh, you haven’t got anything in there, have you?”


“Well I did put some things in there…”


“Yeah, you need to put a slab down or dig it into the ground
because obviously something’s gone in there and removed it all.”


“Yeah, there’s no food in there. Okay. All right then. That was
a week’s worth of squirrel feeding.”


“Yeah exactly.”


(Sound of bricks laying)


So, the next day we go to a big box store to get some bricks. We
lay them all around the base of the composter. The squirrels are defeated.
A few weeks later, I see a huge raccoon shuffling across the backyard.
It knocks the top off the composter and climbs in.


We drive back to the big box store and buy some flat, heavy bricks
to lay on top of the lid. We also buy a few bags of fertilizer, of
course because we still have no compost. I think, this is starting to
feel like work and to be honest – I find it disgusting.


(Sound of brick noise)


“So now, it’s even more challenging to do this.”


(Sound of dumping)


“Ewww. A lot of it is sticking to the pot, which is disgusting but
alright. Uhh, brick back up, auxiliary bricks, okay.”


Now that I had to move those bricks, I was less likely to run out
with just the dinner scraps, and we weren’t mixing the compost very
often, either. So, I tried to remind myself of why I started doing this.


For one, it seemed like a shame to throw vegetable scraps into a
plastic bag and send them to a landfill. Especially when landfill
space is so tight that some Canadian cities are shipping their
garbage to the U.S.


Plus, we have a garden, which could use the nutrients from the
compost. According to George Reimer, those nutrients stick
around a lot longer than the ones found in commercial fertilizer.


I knew all that, and yet, on a stinking hot day in July – and the
composter was stinking because we rarely turned it – I officially
stopped. For a while… for six months. Until recently, when my
guilty conscience prodded me out the door with a bowl of kitchen
scraps.


(Sound of walking in snow)


“We’ve got snow on the ground and a bowl of fresh vegetable
scraps. Umm, interesting. It’s about a third full so there must be
compost under there somewhere.”


Last time I looked, the container had twice that amount in it.
Which makes me think that most of the food has broken down into
something we can finally use on the garden. It gives me an
incentive to start over. Plus, in a few years, I’ll have to compost.


Ottawa will join at least 18 other Canadian cities where residents
are required to throw food scraps into a separate container, and
hey, if all else fails, there’s nothing like a new law to get you
motivated.

A Lighter, Brighter Christmas?

The message from advertisers this holiday season seems to be, buy more because you and your family deserve it. Retailers are hopeful we’ll all spend just a little bit more to make the holidays shiny and bright. The Great Lakes Radio Consortium’s Lester Graham went to the shopping mall with a guy who thinks we ought to scale back our spending during the holidays:


Bob Lilienfeld is one of the co-authors of a book called Use Less Stuff. As you might guess, he’s an advocate of using fewer resources, including buying less stuff during the holidays. We asked him to meet us at a big shopping mall to talk about why he thinks buying less means more.


Lilienfeld: “I want you to go back to when you were a kid. Think about the two or three things in your life, the things that you did that made you really happy. I guarantee none of those have to do with physical, material gifts. They have to do with time you spent with your family or things you did with your friend. But, it wasn’t the time you said ‘Oh, it was the year I got that train,’ or ‘the year I got those cuff links,’ or ‘when I got those earrings.’ That’s the principle difference. We’re trying so hard to be good and to let people know that we love them, but the things that we love about other people and that they love about us have nothing to do with material goods.”


Graham: “There’s a certain expection during the holidays, though, that we will get something nice for the people we love and here at this mall as we’re looking around, there are lots of enticements to fulfill that expectation.”


Lilienfeld: “That’s true, but we’ve been led to believe that more is better, and to a great extent more gifts is not better than fewer gifts. Quality and quantity are very different kinds of thoughts and we’ve been led to believe economically that quantity is more important. But, in reality it’s the qualitative aspects of life that we long remember and really are the ones we treasure.”


Graham: “Now from the news media, I get the impression that if I don’t do my part during the holidays in shopping, that it’s really going to hurt a lot of Americans, the American economy. $220-billion during the holiday season. It’s 25-percent of retailers’ business. So, if I don’t buy or if I scale back my buying, won’t I be hurting the economy?”


Lilienfeld: “It’s always been 25-percent of retailers’ business, even if you go back 30 or 40 years, and that’s probably not going to change. It comes down to your thinking through what’s good for you, what’s good for your family, what’s good for your friends and not worrying so much about what’s good for the economy and what’s good for big companies.”


Retailers are expecting sales to be better this year than last year. So, that simpler lifestyle that Lilienfeld is talking about is not widespread enough to have any real impact on the overall shopping season. But apparently the economy isn’t strong everywhere.


We talked to some shoppers about their holiday shopping plans and the idea of simplifying things. Many of them told us that the economy was forcing them to cut back on gift buying…


Shopper 1: “Well, because of my limited budget, I have to buy, like – I have a list – and I have to buy one at a time, so, being pretty poor is being pretty simple. I’m kind of already living that way.”


Shopper 2: “I don’t need to celebrate Christmas by buying people gifts. And I can give people gifts all year long. And I — Christmas is kind of sham-y to me.”


Shopper 3: “This year, yeah, my family is like, ‘Don’t get me anything.’ I’m going to do something, but hopefully it will be smaller and less expensive and all that.”


Shopper 4: “Well, I don’t feel compelled to buy something because an economist says it’s my part as an American. And I think people are going to get smarter and smarter about how they spend their money and the almighty dollar.”


With the constant messages on television, radio, the Internet and newspapers to spend, there’s a lot of persusive power by advertisers to buy now and think about the cost later.


Since Bob Lilienfeld is such an advocate of a simpler lifestyle, it makes you wonder about his own shopping habits.


Graham: “Do you ever find yourself in the shopping mall, buying stuff for the folks you have on your Christmas list or your holiday list?”


Lilienfeld: “All the time. But, what I try to do is two things. One is think about the fact that more isn’t necessarily better. But the other thing I really try and do is look for gifts that are what I call ‘experiential’ as opposed to material. Tickets. Things where people can go to plays or operas or ball games so that they have an experience. Same thing with travel. I mean, if I could give my father a gift or if I could help him afford to go somewhere, like to see me and the kids, that gift is probably worth a lot more to both of us than if I just gave him a couple of bottles of wine.”


And Lilienfeld says you don’t waste as much wrapping paper when you wrap up tickets.

Room for Wilderness in the Suburbs?

  • Lilies like these reside in the Reinstein Nature Preserve. Environmentalists worry about natural life in the preserve as the state of New York considers opening it up without restrictions.

Imagine a suburban, backyard wilderness where 200 year-old trees still stand. That’s exactly what you’ll find at the 300 acre Reinstein Nature Preserve. It meanders right through the heart of a bustling suburb. The preserve has been limited to small groups led by a nature guide. But there’s a new plan to give unrestricted access. Some environmentalists worry that would ruin the preserve. The Great Lakes Radio Consortium’s Joyce Kryszak takes us to the woods – and to the debate:

Imagine a suburban, backyard wilderness where 200 year-old trees still stand.
That’s exactly what you’ll find at the 300 acre Reinstein Nature preserve.
It meanders right through the heart of a bustling suburb. The preserve has been limited
to small groups led by a nature guide. But there’s a new plan to give unrestricted access.
Some environmentalists worry that would ruin the preserve. The Great Lakes Radio Consortium’s
Joyce Kryszak takes us to the woods – and to the debate:


A Great Blue Heron perches lazily in the distance above an expanse of pink water lilies.
At first Bob Reinstein doesn’t see the bird.


“I should’ve brought my field glasses.”


But then its giant wings spread wide, laboring to clear the water in this serene Monet-like setting.


“The lilies were a gift from two different environmental organizations…”


The man and the majestic heron both seem oblivious to the rush of cars and people just
beyond the edge of the woods. This is the Reinstein Nature Preserve. It’s framed on all sides
by a sprawling suburb of houses and shopping plazas in Western New York. Like his parents before
him, Bob Reinstein says he’s risked his life for nearly sixty years defending this scene; he guards it against trespassers – and sometimes trespassers with guns.


“Their lives were threatened several times, in fact, mine was also. I was unarmed at the time,
but he had pointed his shotgun at me and threatened to shoot. Realizing it was pointing at my face,
I stopped following him.”


But Reinstein never stopped trying to protect the nature preserve his father created half a century ago.
By the time he died in 1984, the elder Reinstein had dug nine ponds, planted thousands of trees,
rare ferns and flowers to compliment the ancient scene. The younger Reinstein says it’s like a
living museum.


“Where else can schoolchildren walk back through history a hundred and fifty years and see
samples of what existed then, that are still here today?”


Reinstein says his father bequeathed the preserve to the state to keep it from being trampled.
He stipulated that it must stay forever wild. People could visit, but only for educational
purposes. And only with a trained nature guide. That could all be changing. A proposal by the
State Department of Environmental Conservation would give the public unrestricted access.


Jane Wiercioch lives in the nearby suburb and loves visiting her backyard wilderness. But today
Weirchioch is handing out petitions here. She hopes to stop the DEC from opening the preserve. She
says it would leave the woods vulnerable.


“I know I came in here the other day for a walk around that lily loop with my great granddaughters
and, of course, they were chasing frogs. So, I’m with them, I’m yelling at them, ‘don’t do anything.’ But can you imagine having people just coming in here and doing what they want?”


State conservation officials say bringing in more people is the whole point. Meaghan Boice-Green
is a spokesperson for the New York State Department of Environmental Conservation. She says all
other department-run properties are open to the public. Boice-Green says unrestricted access would be good for both the public and for the agency.


“We’re not talking about property that hasn’t touched by the hand of man, and in order for us
to obtain the funding to do the habitat maintenance that’s going to be necessary to maintain
this manmade habitat, we have to provide some public access. We’re not going to be able to
access funds to support a property that the public isn’t allowed to access.”


But the state has never had any trouble finding money to maintain the preserve before.
And Boice-Green couldn’t offer specifics about any extra funding.


Terry Boyle has volunteered as a guide at the preserve for eight years. But he agrees the
preserve should be unrestricted. Boyle says visitors can’t have a truly natural experience
if someone’s watching their every move.


“A lot of those people who do want to come in, they want to take photographs, they want to sit
down and reflect for a little bit about what they’re looking at, and that kind of stuff. So,
they can’t go at their own leisurely pace with tour guides, because we have to push them through a little bit
faster.”


But the head of a local environmental group sees it differently. Larry Watson says if the
preserve is opened, there won’t be anything left to look at anyway. He believes the state is
just tired of policing the woods. But Watson says it was Dr. Reinstein’s wish that the
preserve be kept wild. And he should know. As a young boy sixty years ago, Watson spent many
long hours in the woods, helping Reinstein plant the saplings that now tower overhead.


“If they turn this into what they want to, it will be nothing more than a state park.
And we’d rather see it kept as an individual showpiece and a place New York state can be quite
proud of and show the rest of the country what can be done in the way of environmental
conservation.”


The New York State Department of Environmental Conservation says it hasn’t made a final
decision. It will consider the wishes of those who want access to the preserve to remain
restricted. But many people are also demanding it be opened. Ultimately, the state says
it will likely let people come to the preserve whenever they want – and trust them
to be good caretakers.

City Cooks Up New Compost Recipes

  • A pile of food waste awaits processing at a Duluth, Minnesota composting site. A wide variety of materials arrive each day - anything from unused frozen dinners to sheet rock to bird droppings from a nearby zoo. Photo by Stephanie Hemphill.

Lots of people have a compost pile in the backyard. They throw their grass clippings and kitchen scraps in a pile and let it sit. Eventually it turns into rich black stuff that can be spread on the garden. Many cities around the Great Lakes collect residents’ yard waste and turn it into compost on a bigger scale.

Lots of people have a compost pile in the back yard. They throw their grass clippings and
kitchen scraps in a pile and let it sit. Eventually it turns into rich black stuff that can be spread
on the garden. Many cities around the Great Lakes collect residents’ yard waste and turn it into
compost on a bigger scale. In Duluth Minnesota, they’ve taken it a step further. An industrial-
sized compost operation uses some surprising ingredients. The Great Lakes Radio Consortium’s
Stephanie Hemphill reports:

There’s a steady stream of cars and pickups as people drop off leaves and branches. They’re
piling up their yard waste at the compost site of the Western Lake Superior Sanitary District in
Duluth, Minnesota. The Sanitary District takes care of the trash for Duluth and nearby towns.

At the back, four rows of future compost are cooking in the sun. They’re about 6 feet tall and
half a block long. They were mixed by a master chef of compost, Charlie Hitchcock. He’s about
to cook up a new batch. Today’s mix starts with biodegradable bags of kitchen scraps from
several restaurants.

“It’s a small load today, but it’s food waste and there’s animal hair that’s thrown in from some of
the pet grooming places. A lot of protein and nitrogen in that, I guess.”

Hitchcock consults a laptop computer to create his recipe. He plugs in the weight of the food
waste. The computer program tells him the right proportions of wood chips and leaves to mix in.
It’s aiming for the ideal combination of carbon and nitrogen. Most loads are about half wood
chips.

“Because it aerates it pretty good. And then I just keep punching a number in on the leaves until
I get between a 25-to-1 to a 35-to-1 on a C-N-N ratio, carbon to nitrogen.”

(tractor starts)

The key ingredient that’s loaded in Hitchcock’s mixture is different every day. That’s because the
sanitary district is always trying to divert stuff that would normally go to the landfill. Lately
they’ve been going after some of the garbage itself, not just yard waste. And sometimes that
garbage comes from some exotic places.

(bird sounds from zoo)

Dave Homstad takes care of the birds at the Lake Superior Zoo. He’s giving the parrots some
fresh water.

(parrot chit-chat)

He slides out the bottom of the cage and whisks sawdust and bird droppings into a black plastic
bag.

“The composting stuff goes into a black bag, so that we can keep them separate. And then
anything that can be composted goes in here and then eventually into a dumpster for that
purpose.”

The dumpster gets filled with uneaten food, animal bedding, like straw and sawdust, and animal
dung. At the composting site, the dumpster-load from the zoo might be mixed with scraps from a
coffee shop. A commercial fishing operation brings fish guts. Even sheetrock is ground up to
become compost. The latest addition is waste grain from the elevators on Duluth’s lakefront.

(train sound at elevator)

The Cargill elevator handles 50 million bushels of grain every year.

Roger Juhl manages the operation. He says there’s some spillage when railroad cars have to be
changed from one type of grain to another.

“So we have to clean them out and dump them onto the tracks, and then pick them up and put
them in the dumpster. And that’s where they’ll go to this recycling center.”

Juhl says he’ll probably save some money. He’ll still have to pay the hauler to take the grain
away, but he won’t have to pay for dumping it in the landfill. What’s even better, Juhl says he’ll
be doing something good for the environment.

“Hopefully it’ll be useful for something.”

It’s put to use, all right, in Charlie Hitchcock’s compost mixer.

(compost sound back up)

The mixer’s been turning for 15 or 20 minutes. Hitchcock peers into the barrel. The ingredients
look like chunky dirt, and smell like day-old garbage. He reaches in for a handful.

“I do the squeeze test on it. If you get it packed tight without moisture coming from it, it’s within
the 50% range, which is good.”

Hitchcock is learning how to turn an amazing variety of stuff into compost. Some days he gets a
load of spoiled vegetables from a grocery store. Other times it’ll be outdated frozen dinners.

“When I get a lot of wet pasta, I use some sheetrock and mostly grindings. That’s shredded up
tree branches and limbs that we have. I don’t put leaves in it because the pasta’s so wet, it gets
real gumbo-y.”

After six months in a pile, the compost is ready for customers, like Suzanna Didier.

“I mean, I’m glad they’ve figured out a way for us to decrease the amount of garbage that goes
into the stream, into the waste stream, because obviously that needs to be slowed down a bit. So,
it’s great.”

It’s an expensive operation that doesn’t pay for itself. Officials hope to recoup half their costs by
selling compost. As they get more raw materials, it’ll become more cost effective. Someday,
they hope everyone in Duluth will send their kitchen waste for composting.
