At your home, chances are your TV, computer and other electronic gear were made
overseas. That’s because it’s cheaper to make them there. And it’s cheaper to get rid of old
electronics overseas. Someday, your old cell phone or CD player might end up right back
where it started: in China. Ted Land visited a Chinese city where electronic waste , or e-
waste, is shipped by the thousands of tons. Pollution from that waste is threatening the
health of people who live there:


The city of Taizhou is in eastern China. It’s an industrial port city. A lot of the people
who travel here are here on business. Ships loaded with new products are often headed
for the United States. But it’s not just what leaves this city that makes business boom…
it’s also what’s coming in:


“I know it’s polluted here but it’s not a big deal. The most important thing is my
children, that’s the reason why I found work here.”


Liu Qinzhen works at this Taizhou scrap plant. It’s the final stop for some of the nearly
4,000 tons of scrap and e-waste that enters the port each day. Liu is one of hundreds of
workers who squat under an outdoor pavilion picking apart old circuit boards and wires.
She works 9 hours a day, 7 days a week, earning about 130 dollars a month.


The work is dangerous. She and the other workers are exposed to harmful chemicals
from e-waste such as lead and mercury. The 23-year-old moved here for this job because
she needed to support her two kids:


“I used to work in a shoe factory but then I had a baby and it’s not convenient to have a
baby there so I moved here even though the pay is the same. I come from the countryside.
You can’t earn money on a farm.”


The plant where she works is considered safer than scrapping these materials in the
countryside where families work in their front yards and in their homes. They melt
circuit boards and burn wires to extract bits of valuable copper and gold.


Environmental organizations have documented evidence that what’s left over after the
valuable metals are retrieved is dumped into local rivers and streams:


(Land:) “I noticed when we arrived they shut down the other door of that other shop?


“They are doing the same kind of e-waste, but they are afraid of being discovered by
others.”


Afraid, says Taizhou resident Chen Yijun because what they’re doing is illegal. Chinese
law forbids the import of e-waste, yet piles of foreign electronics litter the countryside
and pour into scrap plants daily.


Yijun is a teacher at Taizhou #1 High School, where students are concerned about what
the e-waste industry is doing to their environment. They’ve been testing the water in
local streams, looking for signs of harmful chemicals:


On this day they draw several gallons from a stream. The banks are littered with piles of
electrical cable. Chen Zhengyan has been working on the project for years:


“The frogs here are different from frogs in other places because sometimes they have
extra limbs. We are sure the pollution is from e-waste because in this area there is no
other industry.”


Chen and her colleagues say this pollution is harmful to people, too. They tell local
government officials such as Liang Xiaoyong that something has to be done to improve
the situation. But, Liang says there’s only so much the government can do to combat an
illegal industry that so many residents make their living off of. He says cutting off the
imports is difficult because sometimes e-waste is hidden in with other scrap. He doesn’t
deny the waste industry is a big business here:


This industry generates a lot of tax money for us in the form of tariffs. So, if this industry
doesn’t exist, the Taizhou harbor won’t survive.


Jim Puckett is coordinator of the Basel Action Network, a Seattle based group that
confronts toxic trade issues around the world. He says it’s not that the Chinese
government is unwilling to stop imports, it’s simply unable to stop them.


“They’ve banned the import, the problem is they can’t control that flow, it’s just coming at
them container load after container load through various ports and they can’t possibly check every
single one.”


American waste is literally fueling the fires burning electronics that dot the countryside in
China. And many of the original owners of this gear had taken it to be recycled, and
thought they’d done the right thing. But, often it ends up on a ship, headed for scrap
yards overseas.


About seven thousand miles away from Taizhou, practically the other side of the globe,
there’s a warehouse in Springfield, Illinois stacked with old electronic gear.


The Illinois State Department of Central Management Services, or CMS, disposes of old
state property, including old copy machines, computers, and monitors. In 2005, CMS
was contacted by the Basel Action Network with some disturbing information. The
group was finding State of Illinois computers dumped in developing countries around the
world. Curtis Howard is manager of CMS state and federal surplus property:


“It hit me pretty hard, the fact that, not realizing, you know I always look at it, these guys
were here, they come in, they bid on our property, you know I’m maximizing the return on
the state’s investment, I’m doing a good job, I never really thought about the tail end of
the dragon.”


Basel Action Network coordinator Jim Puckett says if the Chinese are unable to stop the
imports, then it’s up to the United States to control what they export:


Other countries have laws forbidding it, laws controlling it, but in the United States, we
don’t even have a law to control this export.


The U.S. is one of only a handful of countries that have not signed and ratified the Basel
Convention, an international treaty that bans hazardous waste exports. That means if
anything is going to be done to stop electronic waste from polluting countries overseas,
it’s going to be up to the States to take action.


It starts with buying electronics from companies that make products that are more easily
recycled, and ends with making sure old electronic gear is getting into the hands of
responsible recyclers who don’t simply ship the e-waste to scrap yards overseas.

High Tech, High Voltage Cars

These days, hybrid gas-electric vehicles make up just a tiny fraction
of total car and truck sales. But that’s expected to change.
With higher gas prices… demand for hybrids is going up.
And car companies are stepping up their hybrid production. But there’s
a shortage of people who know how to fix hybrids. Rebecca Williams
reports some mechanics are getting a crash course in hybrids:


Mike Beukema’s been a mechanic for more than 18 years. So he’s seen
cars change a lot. But opening the hood of a hybrid car… that pretty
much changed his life:


“This car just fascinates me altogether so that was the perfect fit.
When it came out, I says this is what I want to be all about!”


He loves the technology. He loves that every time you hit the brakes
you recharge the car’s battery. He loves all the little computers that
tell him exactly what needs fixing.


But there’s one thing that took some getting used to:


“The whole issue of safety was freaky at first because you almost
didn’t dare work on them because they were letting you know exactly how
dangerous it was.”


It’s dangerous because you can get zapped by the high voltage battery.


“These have circuit fuses in ’em at 15 amps – there’s plenty of power
there. Not something you want to mess with.”


You can actually get electrocuted.


Mike Beukema’s got experience with hybrids. He worked at Toyota when
the first generation Priuses came out.


Beukema says the high voltage batteries are pretty intimidating for the
professionals, let alone backyard mechanics. And to really know what’s
wrong with a hybrid system, there’s a big thick manual you have to
read. And c’mon, who wants to read the manual?


Beukema says all this means working on hybrids is a pretty big shift
for mechanics. He says at this point most people who know how to fix
hybrids work at dealerships. There aren’t a whole lot of independent
shops that can fix them. That could be a problem if you like to shop
around to save money on car repair. Or if you break down in the
middle of nowhere.


That’s why, here and there, hybrid classes for independent mechanics
are popping up.


Kurtis LaHaie teaches auto tech classes at Macomb Community College in
Michigan. He recently started hybrid classes here. Today, he’s got a
room full of high school auto tech teachers.


He’s holding their attention… even after lunch.


“Too many volts, too many amps, you’re being cooked, literally inside.”


Then he pulls out the face shield and the big orange gloves.


“Now, as a technician, we’re going to need some new tools. These are
lineman’s gloves – people up on telephone poles? That’s what they wear.
That’s what we’re going to wear, same thing.”


LaHaie says electricity can get through even a tiny pinhole in the
gloves… so you have to be careful.


There’s also a big shepherd’s hook you’re supposed to have on hand.
Just in case you have to save your buddy from being electrocuted by a
live battery.


Joe Hart had his eye on that shepherd’s hook. It’s not the kind of
thing that helps sell a guy on hybrids:


“I’m an internal combustion guy, a technician, but you’ve gotta embrace
change and you’ve gotta accept the fact that we’re going to move from
an oil society at some point and I want to be there when it happens, I
want to be ahead of the game rather than trying to catch up.”


Hart might not have much of a choice.


Instructor Kurtis LaHaie says even new internal combustion cars are
getting more complicated. Let alone hybrids:


“If you don’t keep up, you’re going to fall by the wayside. The old
backyard mechanics, they’re very hard to maintain these cars, they’re
very sophisticated. This is just the next level for them to get into.
There’s room for everybody but I think the guys who take the lead in
this, especially now, will take the lead in the future and will do very
well.”


(Sound of grandfather clock chiming)


Mechanic Mike Beukema is hoping that’s true. After a long career at a
dealership, he’s just opened his own shop specializing in hybrids.
Right now, it’s a little lonely for him.


“I’m the service writer, the person that answers the phone, the person
that fixes your car, and person that collects your money – so I am, I
guess, everything here right now.”


Beukema says with any luck, that won’t last too long. He sees his shop
getting big enough that he can quit fixing cars himself. His dream is
to hire guys fresh out of trade school and train them to be experts on
hybrids and other cars of the future.

Road Salt Damage

  • Overuse of salt can cause damage to concrete, steel and the environment. (Photo by Lester Graham)

Each year about 118,000 people are hurt and 1,300 people are killed on
the roads during snowy and icy conditions. So, snowplows hit the
roads, scraping snow and ice off the surface… and spreading
incredible amounts of salt on highways, streets and roads to help keep
them clear. Lester Graham reports there’s some concern about the long-
term effects of all that salt:

Each year about 118,000 people are hurt and 1,300 people are killed on
the roads during snowy and icy conditions. So, snowplows hit the
roads, scraping snow and ice off the surface… and spreading
incredible amounts of salt on highways, streets and roads to help keep
them clear. Lester Graham reports there’s some concern about the long-
term effects of all that salt:


This dump truck is getting ready for a load of salt for a coming
winter storm. Salt helps make icy roads safer. It helps prevent
people from slipping and falling on sidewalks. And… it’s pretty
cheap. But there are problems with salt. Salt pollutes and salt
corrodes.


Mark Cornwell has spent a good deal of his career trying to convince
highway crews that there are better ways to keep things safe and reduce
how much salt is dumped on roads and sidewalks:


“Salt basically damages just about everything it comes in contact
with. Salt moves through concrete and attacks structural steel,
bridges, roads, parking structures; it eats the mortar out of bricks
and foundations. It damages limestone, you know, just on and on and
on.”


So, even though salt is cheap, the damage it does costs a lot. It’s a
hidden cost that’s seldom calculated. Imagine the cost of having to
replace a bridge five years early because the structure is weakened by
salt. And then there are your direct costs: trying to keep salt
washed off your vehicle, and still seeing rust attack your car.


Cornwell says there are some cities and road commissioners working to
reduce the amount of salt spread on the roads. But in most places, the
political pressure to get the salt trucks out early, and laying it on
thick to keep drivers happy, outweighs any concerns about trying to
reduce the salt:


“I’m sure the public expects full attention to snow and ice. And they
have absolutely no understanding, however, of what it costs to provide
that.”


Nobody thought a lot about the damage salt was causing until the last
couple of decades. In a few places, the people responsible for keeping
the roads and walkways safe have been trying to reduce the amount of
salt they use and still keep public safety tops on the list of
concerns:


“So, this is our shops. The brine-maker is right here.”


Marvin Petway is showing me some of the tools in his arsenal to reduce
how much salt is used and still keep things safe. He works at the
University of Michigan, where there’s a goal to cut the amount of salt
used in winter in half. What they’ve learned is using innovative ways
of putting down salt can actually help melt snow and ice faster. One
way is to mix it with water to get the chemicals in salt working
a little more quickly:


“Why use 5 pounds of rock salt when you can use 2 gallons of liquid
salt? We’re able to get better coverage, quicker, better cost, and
we’re putting the material that is effective in reducing ice build-up
directly to the area where we don’t want ice located.”


The crews trying to reduce salt use computer assisted spreaders to
measure out only the salt needed, they mix in less corrosive chemicals
that make salt brine more effective, and even just wetting the salt in
dump trucks with chemicals all help to melt snow and ice faster and in
the end use a lot less salt.


Nothing is going to replace salt altogether, but those efforts can add
up to a lot less salt. That means less destruction of infrastructure.


But there are more reasons for reducing salt than the damage to
roadways and parking decks. Salt also damages the environment:


Mark Cornwell first noticed the effects of salt because he was a
horticulturalist. He’d work all spring, summer and fall planting
shrubs, make the grass green, tending beds of flowers. Then the winter
would come:


“Unfortunately what we were doing in six months of winter was
undoing everything we did in the other six months of the year.
If you’re going to get ahead, you’ve got to solve the problem
and in my mind, that was misuse of salt.”


Use too much salt and it kills plants. And it turns out the cost of
using all that cheap salt could be even greater than anyone guessed.
For decades, it’s been assumed that rain washed away most of the salt, but
studies in Ontario find that a lot of the salt doesn’t get washed
away.


Instead, a good deal of it is percolating down into shallow aquifers.
Researchers predict that in the future we’ll start find salt is getting
into the groundwater that supplies many of the wells where we get our
drinking water.

A “town hall” type forum on Great Lakes issues is now as
close as your nearest computer. The Great Lakes Radio Consortium’s
Chuck Quirmbach reports:


There are forty-two million people in the Great Lakes region and it’s
a little hard getting them all in the same room, but now, you can go to
a computer website for discussions about Great Lakes issues, and to
share your favorite Lakes experience.


The Wisconsin-based Biodiversity Project has set up the interactive site,
great lakes town hall dot org. Jeffery Potter is a spokesperson
for the Project.


“When it came to the Great Lakes Town Hall, we wanted to create a
resource where people across the region could come together, share
their ideas in an inclusive environment, and really talk about and get
more engaged in issues that are vital to protect the Great Lakes as a
resource for all of us.”


Potter says the website features a weekly guest expert, and there’s
a moderator on duty. Anyone can look at the site, but you’ll be asked

Searching for E-Waste Solutions

If you bought a new computer over the holidays, there are plenty of
places to drop off your household’s old computer, but to prevent more
of the old monitors, laptops and other items from winding up in
landfills, some Midwest states are looking to make sure computer
makers get involved in recycling their products. One of the few
manufacturers that already helps re-use old computer parts is
Texas-based Dell, Incorporated. The Great Lakes Radio Consortium’s
Chuck Quirmbach went to a Dell-sponsored recycling center and has this
report:


About a year ago, Dell helped set up and publicize a computer
recycling plant at a Goodwill Industries facility in Dell’s home city
of Austin.


(Sound of clunking)


Goodwill employees and volunteers sort through the hundreds of
boxes of computers and computer parts that are dropped off – at no
charge to the consumer – at the site. Newer computers are set aside
for repairs, and hard drive memories are erased. Older computers go
to a bench where workers like Paul take apart (or demanufacture)
them.


“I’m taking apart all the useable parts. Motherboard, power sources,
cards, ports, metal goes into bins, plastic goes into bins for
recycling and what not.”


(Sound of ambience switch)


Goodwill sells the reusable parts at its retail store elsewhere in the
building. Used LCD monitors, for example, go for as low as twenty
dollars.


Manager Christine Banks says some of the equipment is under
a 30-day Goodwill warranty. Other parts can be exchanged if the
customer isn’t satisfied. Banks says Goodwill is happy this computer-
recycling program makes a profit.


“Our operation does. However, there are 7 or 8 other Goodwills
throughout the country that do this that barely break even. We’re just
fortunate we have higher tech donations, a pool of employees with
more technology, it’s very tricky.”


Some states charge high disposal costs for unwanted computer parts,
which can contain potentially harmful chemicals. Those high costs can
make it difficult for a recycling program to get off the ground, but
environmental groups say the fast-growing pile of circuit boards,
monitors, and plastic parts can leach poisons like lead, mercury, and
cadmium into the environment.


They say small-scale projects like the one in Austin have to be part of a
broader effort to keep electronic waste out of the nation’s landfills. That
effort could include government mandates forcing manufacturers to
safely dispose of old products.


Robin Schneider is with the Austin office of the National Computer
Takeback Campaign.


“So, to really deal with the environmental problems of millions of
pounds of toxins, we’re gonna need something bigger than this. This is a
piece of it…and gonna need lot of pieces of it.”


Schneider says she’s encouraged that some Midwest states are
looking into manufacturer takeback programs. She acknowledges that
recycling may drive up the cost of new computers, but she also says
manufacturers may start redesigning computers so that it’s more
profitable for the companies to take them back.

Moving Away From Tail Pipe Tests

There’s a new trend in how states with air quality problems carry out vehicle emissions testing. Some say it will allow cars that give off harmful pollutants to stay on the road. The Great Lake’s Radio Consortium’s Amanda Vinicky reports:


States that are required to test emissions usually test a car’s tailpipe. Illinois is switching to “onboard diagnostics.” That means the vehicle’s onboard computer gives testers all the information they need.


But older cars don’t have computers, so the state’s exempting all cars made before 1996 from testing. Brian Urbaszewski is with the American Lung Association.


“When you stop testing them, people aren’t even going to know their cars are polluting. Or, even if they know, they’re going to be less likely to fix it because there’s no penalty involved.”


The Lung Association says the Illinois Environmental Protection Agency’s own documents show that air quality will get worse after the 2007 change.


State and federal EPA officials admit that’s true, but they say fewer of those cars will be on the road each year. They say computer testing is better because it detects problems before they happen and it’s cheaper.

Scientists say a newly dedicated computing system called the
Open Science Grid could improve research on the environment. The Great
Lakes Radio Consortium’s Chuck Quirmbach reports:


Computer grids allow users in one group to tap into another group’s
computer data. Several Midwest universities have been working with
federal agencies on a grid for physicists, biologists, and others to be
used in scientific applications.


The hope is that the Open Science Grid will help different fields of science connect. Dane Skow is with the Fermi National Laboratory near Chicago. He says researchers might combine satellite images of crops with data on water quality.


“You may be able to track algae plumes so that you can see fertilizer runoff patterns from fields. There’s a whole bunch of things people are doing, looking at, and tying this kind of data together.”


Skow says creators of the Open Science Grid have put in controls to try to limit who has access to the system. He estimates the grid costs about ten million dollars to build.

New Mining Operation Worries Neighbors

A multinational mining company is planning to mine for nickel near the shore of Lake Superior. But some mining experts and the community don’t want the mine to be built. They say there’s no way to make sure the mine won’t damage the environment. The Great Lakes Radio Consortium’s Chris McCarus reports:

A multinational mining company is planning to mine for nickel near the shore of Lake Superior. But some mining experts and the community don’t want the mine to be built. They say there’s no way to make sure the mine won’t damage the environment. The Great Lakes Radio Consortium’s Chris McCarus reports.


The price of nickel has tripled in recent years. It’s needed for electronic produces such as computers. It’s used to produce cars. And nickel is even used in air pollution control equipment. If it’s approved, this would be North America’s only active nickel mine.


Kennecott Minerals Corporation says it’ll mean 120 jobs for local workers over a 10-year period. The state of Michigan has been lagging behind the rest of the nation in job recovery and in the northern reaches of the state good jobs are really hard to find.


The mine will cost 100 million dollars to set up. But the value of the nickel ore in the ground is somewhere between one and three billion dollars. So the company could make hundreds of millions in profit.


Scientists and activists say that this nickel mine could be even worse than the iron and copper mines of the past.


That’s because it would require mining through sulfide minerals. When they mix with water and oxygen, they can become sulfuric acid, just like battery acid. The industry calls the problem acid mine drainage. It can kill fish and wildlife and pollute water.


Michelle Halle is a lawyer for the National
Wildlife Federation and a local resident. She’s got one question.


“I’m always interested in the answer to the question about whether he believes that a mine can exist with 100% perfect track record.”


It’s a rhetorical question. She’s confident that the company won’t be able to meet the newer, stricter standards for getting a permit to mine.


“No human error, no design flaws, no natural disasters that are going to cause an impact… I don’t think that any company can say yes to that honestly.”


The mining company says there’s always some risk. John Cherry works for Kennecott Minerals Corporation. Cherry insists the company’s design is the best, and the safest. Although he says it’s impossible to guarantee against accidents at the mine.


“We can get in a crash on the way home today too. You design it with a safety factor built into your design. You have a very robust design. That’s your first step. You make your system as structurally competent as you can. Make it as bulletproof as you can.”


Cherry says the next steps are to install a monitoring system to detect the smallest problems. And if there are any problems, the mine will have a contingency plan with the right materials and properly trained people on hand.


State law requires the company to pay all of its accident insurance up front. They can’t just pay in installments. That way, the company will pay to clean up any mess, not the state or the community. Minnesota has a similar law. And In Wisconsin, People Against Mining got the state to establish a moratorium on sulfide mining


David Chambers used to work as a geologist for a mining company. And now he works for the Center for Science in Public Participation. He says, at the nickel mine planned in Michigan, groundwater contamination is possible and would be dangerous.


“Probably the most likely event is an accidental release from the mine. All mines have problems. It’s likely that somebody won’t turn a valve the right way or a big storm comes and there’s an overflow.”


Chambers says a mine collapse would be the most destructive. But, he says, even for the accidents that will not devastate the environment, the company and the community should plan, because they will happen.


(Sound of trucks)


On the road leading into the wilderness area where the mine would operate, local road crews are doing routine maintenance. Right now, most people who use the road are hikers, kayakers and fishermen. The pristine waters of Lake Superior and surrounding lakes and streams attract them here.


Kristy Mills is a store owner. She thinks a sulfide mine would only mean heavier traffic of trucks carrying away nickel ore. She says it wouldn’t bring in the tourist dollars the area needs.


“We don’t like to see that kind of growth. I think it’s a poor way of investing into our future. You know, we need to encourage tourism and visitation, not mining and hauling ore around in big trucks. It’s gonna be interesting.”


Many local residents and environmental activists feel the area should have learned lessons from the region’s past mining heritage. The precious ore is removed. People somewhere else get rich. And the legacy of pollution is all that remains when the mines are closed. So now, they’re hoping if it comes, this mine will be different.

There are several groups in the region working to protect and restore the
endangered Karner blue butterfly. Now these efforts could be helped by a
new computer mapping and statistical modeling technique. The Great Lakes
Radio Consortium’s Chuck Quirmbach has more:


Habitat maps for endangered species can be based on broad general
estimates. But some scientists hope a combination of computer
software and data such as soil type and vegetation will lead to
more accurate information on where the Karner Blue butterfly lives.


David Mladenoff is a professor of Forest Ecology at the University of
Wisconsin – Madison. He says having a better idea of the butterfly’s
habitat might save companies money on things like surveying costs.


“In other words, if they say we’re planning on doing work on this utility
right away or potentially harvest this area of forest, is this even
a place we have to be concerned about for the Karner Blue butterfly
occuring?”


The U.S. Fish and Wildlife Service, a state agency, and some power
companies are funding a computer mapping project in Wisconsin.
Scientists say the same technique could be used in other states.

Wifi System to Help Save Money on Utility Bills?

  • If only your electricity meter could talk... (Photo by Kenn Kiser)

If the summer heat’s had you cranking up the a/c… you might be anxious about getting a big bill in the mail. Imagine if your house could send you an email to warn you that you’re spending a lot… before the bill arrives. The Great Lakes Radio Consortium’s Rebecca Williams explains:

If the summer heat’s had you cranking up the A/C, you might be anxious about
getting a big bill in the mail. Imagine if your house could send you an
email to warn you that you’re spending a lot before the bill arrives. The
Great Lakes Radio Consortium’s Rebecca Williams explains.


In the future, your electricity meter could talk to you.


You’d be able to type into your computer how much you want to spend on lighting and cooling
your house each month. Using wireless technology, your utility meter would
then send you an email when you’re going over those goals.


It’s a system created by mechanical engineering students at the University
of Michigan. Professor Steven Skerlos advises the team.


“As a recent homeowner, it was very obvious to me that even I had little
awareness of the impact that I was having and the consumption of course
until it was way too late. The bill comes a couple months later and you
can’t go back in time and turn down the thermostat or use less water.”


Skerlos says the system can also be used in water and gas meters.


But it might be several years before you can get the new system. Skerlos
says he’s had interest from the companies that make the meters, the next
step is getting utility companies to buy in.
