Americans get rid of almost 300 million scrap tires every year.
Historically, a lot of used tires have ended up at the bottom of
ravines or in huge tire piles. These piles have created eyesores,
toxic fire traps and places for mosquitoes to breed. But Ann Murray

Americans get rid of almost 300 million scrap tires every year.
Historically, a lot of used tires have ended up at the bottom of
ravines or in huge tire piles. These piles have created eyesores,
toxic fire traps and places for mosquitoes to breed. But Ann Murray
reports that the days of widespread illegal dumping and monster tire
piles are waning:


Michelle Dunn is making her way through shoulder high knotweed to
show me an urban tire dump:


“This is the start of the tires. They’re all entwined in here.”


About 300 tires have been chucked over the hill in this quiet
Pittsburgh neighborhood. Dunn’s with a non-profit that helps
communities clean up old dump sites. She says illegal tire dumping is
still a problem but not the gargantuan problem it used to be:


“I don’t think you’re seeing new major piles appearing. The regular
Joe isn’t dumping as many tires because people are now becoming
educated. They have a service they can take their tires to have them
disposed of properly.”


In many states, the place to take old tires is now the neighborhood
tire store. Since the early 1990s, about 35 states have required tire
dealers to collect small fees to dispose of used tires. Now fewer
people dump tires and about 4 out of 5 scrap tires have been
cleaned up. Numbers have nosedived from a billion stockpiled tires to
less than 200 million.


Not all states have had equal success reducing their cache of old
tires. Some states such as Alaska, Wyoming and Nevada are still
struggling. Their rural landscapes have made it hard to catch illegal
dumpers and collect tires. Many other states have stepped up
enforcement. They now make dumpers pay to clean up waste tire
sites and register scrap tire haulers. But Matt Hale says new laws
aren’t the only reason scrap tire programs are working. Hale directs
the division of solid waste for the US Environmental Protection
Agency:


“In many cases a successful program is the result of being near
markets for tires. In the southeast for example, tires are in demand as
a fuel use and that certainly makes state tire programs in that part of
the country easier.”


Stricter waste tire laws have made it easier for the tire
recycling industry to take hold. Dave Quarterson is a senior director
with Liberty Tire. Liberty’s the biggest tire recycling company in the
country:


“It has been difficult for companies like ours in the past to look at
having to invest 5 or 10 million dollars into a facility to recycle tires
and then to have to compete on the street with a guy with a $1000
pickup truck who’s rolling ’em down an embankment somewhere.”


In 1990, very few of the 300 million scrap tires generated each year
were re-used. Today about 90 percent are recycled. A majority of
these tires are chipped and shipped to cement kilns and paper mills
to be burned for fuel. A fuel source that US EPA says is relatively
safer than burning coal but environmental groups say is still polluting.


Tire recyclers like Liberty Tire are now in big demand. Liberty uses
almost 75 million scrap tires a year. Their headquarters
plant specializes in making “crumb” rubber. Crumb’s used in
everything from football field turf to brake lining. It’s made from
shredded tires that are frozen with liquid nitrogen and then pulverized
into various sized bits.


Dave Quarterson, says tire recyclers are starting to move away from
producing tire chips for fuel to making newer products like crumb
rubber:


“We’ve got a lot more money into producing it but it’s a lot more
rewarding financially.”


States are also encouraging new uses for the decades old tires that
still remain in big, abandoned piles. Even with this backlog of old
scrap tires, states and recyclers are optimistic that growing markets
and new laws mean more and more scrap tires will have a useful
second life.

State Car Emissions Ok’d

A federal judge has ruled in favor of a state law aimed at cutting greenhouse gases from
cars and light trucks. Mark Brush has more:


Like 11 other state laws – the Vermont law calls for a 30% cut in heat-trapping gas
emissions by 2016. Automakers sued Vermont saying these kinds of regulations would
hurt the industry and can not be made by individual states. A federal judge disagreed.


Michelle Robinson is with the Union of Concerned Scientists. She says the judge heard
from the group’s engineers. They designed a minivan that would meet these new
standards with technology that exists today:


“There’s no need to change the look of the vehicle or the performance of the vehicle in
any way. So you could maintain the levels of safety and performance that drivers expect
while improving the pollution performance of the vehicle.”


Aside from a likely appeal from the auto industry, the states are also waiting on the
Environmental Protection Agency. They have to get a waiver from the EPA before they
can enforce their laws.

Legislation Dividing Organic, Biotech Farmers

The nation’s agricultural seed companies are fighting local restrictions on
their genetically engineered products. They say it’s the federal
government’s job to regulate food safety, but critics say federal agencies
aren’t doing a good job of testing genetically modified food for safety.
They’re backing the right of local governments to regulate genetically
engineered crops themselves. The Great Lakes Radio Consortium’s
Sarah Hulett reports:


Genetically engineered crops are created when genes from other plants,
animals or bacteria are used to alter their DNA.


Critics call them “Franken-foods,” and two years ago, three California
counties banned farmers from growing genetically altered crops. That
alarmed the agribusiness industry, and now it’s fighting to keep that from
happening elsewhere.


So far, the industry successfully lobbied 14 states to pass laws preventing
their local governments from putting restrictions on engineered crops.
Four other states are considering similar measures.


Jim Byrum is with the Michigan Agri-Business Association.


“Frankly, it’s pretty frustrating for us to look at some of the rumors that
are floating around about what happens with new technology. It’s
reduced pesticide use; it’s reduced producer expense in production. It’s
done all sorts of things.”


Genetically engineered seeds are created in the laboratories of big seed
companies like Monsanto and DuPont. The modified plants can produce
higher-yield crops that make their own insecticides, or tolerate crop-
killing problems such as drought or viruses.


Proponents of the technology say genetically altered crops have the
potential to feed the world more efficiently, and they say it’s better for
the environment. That’s because the crops can be grown with fewer
polluting pesticides, but critics say not enough is known yet about
engineered crops’ long-term ecological impact, or on the health of
people who eat them.


(Sound of farm)


Michelle Lutz is among the skeptics. She and her husband run an 80-
acre organic farm north of Detroit. She’s watching about a dozen head of
the beef cattle she’s raising. They’re feeding on cobs of organic corn
grown several yards away.


“I’m surrounded by conventional farmers. The farmers right over here to
my east – they’re good people, and I don’t think they would intentionally
do anything to jeopardize me, but they are growing genetically modified
corn.”


Lutz worries that pollen from genetically modified corn from those
nearby fields could make its way to her corn plants – and contaminate
her crop by cross-breeding with it. Lutz says people buy produce from
her farm because they trust that it’s free from pesticides, because it’s
locally grown, and because it has not been genetically altered. She says
she shares her customers’ concerns about the safety of engineered foods.


Lutz says letting local governments create zones that don’t allow
genetically engineered crops would protect organic crops from
contamination.


But Jim Byrum of the Michigan Agri-Business Association says no
township or county should be allowed to stop farmers from growing
genetically modified crops. He says every engineered seed variety that’s
on the market is extensively tested by federal agencies.


“Frankly, that evaluation system exists at the federal level. There’s
nothing like that at the state level, and there’s certainly nothing like that
at the local level. We want to have decisions on new technology, new
seed, based on science as opposed to emotion.”


Critics say the federal government’s evaluation of genetically modified
crops is not much more than a rubber stamp. The FDA does not approve
the safety of these crops. That’s just wrong.


Doug Gurian-Sherman is a former advisor on food biotechnology for the
Food and Drug Administration.


“It’s a very cursory process. At the end of it, FDA says we recognize that
you, the company, has assured us that this crop is safe, and remind you
that it’s your responsibility to make sure that’s the case, and the data is
massaged – highly massaged – by the company. They decide what tests
to do, they decide how to do the tests. It’s not a rigorous process.”


Gurian-Sherman says local governments obviously don’t have the
resources to do their own safety testing of engineered foods, but he says
state lawmakers should not allow the future of food to be dictated by
powerful seed companies. He says local governments should be able to
protect their growers and food buyers from the inadequacies of federal
oversight.
