Over the last 30 years, plastics
have become indispensable on America’s
farms. They save farmers time and money.
The problem is agricultural plastics are
filling up landfills. In some places,
farmers actually burn the plastic. That
releases dangerous chemicals into the air.
David Sommerstein reports
on a new effort to bale plastics and recycle
them:

Farmers must have been paying attention when Dustin Hoffman got that
famous piece of advice in ‘The Graduate’.

“I just want to say one word to you, just one word.”

“Yes, sir?”

“ Are you listening?”

“Yes, sir, I am.”

“Plastics.”

Plastics are all over the farm today. Plastic greenhouse covers. White sheets
to wrap hay bales. Black plastic feed troughs.

(sound of moving troughs)

Dale Tetreault shakes a tall pile of the feed troughs on his dairy farm in
northern New York State.

“They’re a hard plastic and they hold molasses and minerals.”

Tetreault says the plastics are handy – essential, really – to keep feed fresh
for his 500 cows. But the material’s hard to re-use because it gets dirty and
tears easily.

So Tetreault’s left with a decision – spend a thousand dollars a year to truck
them to the landfill. Or burn them, polluting the air and water.

“Yeah, exactly, I mean, we’re not talking about some light piece of plastic
here. We’re talking about heavy duty plastic.”

A new machine is giving Tetrault a third alternative. It goes by the name of
Bigfoot.

(sound of motor starting up)

Bigfoot is a portable hydraulic press. It crushes used plastic and ties it up
in bales.

“Quite an interesting contraption, that’s for sure.”

Tetreault’s been saving up used farm plastics for a couple months for this
test run.

“Alright, we ready to try this?”

That’s Steve Mahoney, a farm educator with the local soil and water
conservation district. He bought Bigfoot with a $35,000 state grant.

(sound of engine running)

Mahoney and some farmhands stuff dirty plastic sheets into the baler, then
Bigfoot crushes it down. That makes room for more.

(crushing sound)

“Okay, so go on back up.”

Mahoney teaches the farmhands how to run Bigfoot. With the help of the
local farm extension office, he’s baled plastics at nine farms so far. He
wants all of the area’s farmers to share Bigfoot, to keep plastics out of the
landfill or burn pile.

“It’s an obvious problem on the farms. It’s necessary, but the disposal of it
is a problem.”

The big plan is to recycle the plastic. Mahoney’s coordinating with a
recycling firm in Minnesota to pick up 40,000 pounds of plastic bales. They
could be made into plastic lumber or shingles or road filler.

The thing is, there isn’t much of a market for low-grade, dirty plastic right
now. Lois Levitan directs New York’s Ag Plastics Recycling Project at
Cornell University. She says as fuel costs rise and more farmers bale their
plastic, that might change.

“Markets want to know that there’s a certain quantity of product at a
certain level of quantity and they’re going to become increasingly interested
when they know there’s a steady stream.”

(sound of Bigfoot machine popping out a bale)

“Ok, that’s it, that’s the finished product.”

Steve Mahoney presses a button and out pops a thousand pound bale of
plastic. Farmhand Lennie Merculdi brushes his hands.

“Put it this way, trying to put it in a dumpster, to the barn, and never having
enough room for the garbage, that’s not good either. What’s a few minutes?
You get rid of the plastic, it’s convenient, you tie it up and away it goes.”

U.S. Lax on Chemicals

News about dangerous chemicals in toys,

News about dangerous chemicals in toys,
cosmetics and cleaning products has a lot of
Americans spending extra money. People want to
make sure they’re choosing things that are safe
for their families. Julie Grant reports that
other countries are ahead of the US in efforts
to improve the safety of all products:

So you might expect that the government has tested those
chemicals to make sure they’re safe. But you’d be wrong.

Daryl Ditz is senior policy advisor at the Center for
International Environmental Law.

He says the US Environmental Protection Agency has never
assessed the hazards of most chemicals used in every day
products.

“That means the EPA doesn’t know, and you and I don’t know,
which materials on the shelves are more dangerous and
which are less.”

Ditz says only a few hundred chemicals have been
thoroughly tested by the U.S. government, but there are
80,000 chemicals used in products on the market.

In the U.S., the EPA has to prove a chemical is harmful to
keep it off the market.

(sound of toy store)

Dorothy Bryan is shopping at this upscale toy store in Northeast Ohio.

She’s got three grandkids. She’s looking at an
organic cotton bunny, colorful wooden blocks, and of course
Thomas the Tank Engine. She
pays more for toys at this store than she would at the big box
retailer. But Bryan says they’re worth it.

“They’re not toxic. That’s the big part. They’re not the
plastic toxic things.
I purchase usually the wooden toys. The little one puts
everything in his mouth.”

But most kids’ toys are made of plastic. And lots of plastics are made with phthalates. It makes them pliable.

But phthalates are endocrine disruptors. They’re gender-bender chemicals that make girls develop earlier and reduce testosterone levels in boys.

That’s why
California has banned the use some phthalates in toys. So
have Japan and the European Union.

But Daryl Ditz, chemical expert at Center for International
Environmental Law, says regulators in the U.S. don’t have
much power to ban phthalates or other chemicals.
Chemicals here are innocent until proven guilty.

“That is, companies can sell virtually anything in a product or in a barrel unless it’s been proven
to be dangerous.”

But other countries are starting to take the opposite
approach. Ditz says the European Union is rolling out a new
set of laws that make chemicals guilty until proven
innocent.

“They’re putting the responsibility squarely on the shoulders
of the chemical makers. As opposed to having the
environmental authorities look for a needle in the haystack,
they’re saying, ‘this should be the responsibility of the
companies who make these materials.’”

Under the EU law, manufacturers will have to study and
report the risks posed by each chemical: whether they
cause cancer, birth defects, or environmental problems.

The Bush administration and chemical manufacturers tried to
block the European law. But they couldn’t.

Ditz says leaders in the
chemical makers’ trade group are now running around like
their hair is on fire. They’re worried – the costs to comply
could be in the tens of millions of dollars for some
companies that export chemicals to Europe.

But many individual companies have already started to
comply with the law.

Walter van het Hoff is spokesperson for Dow Chemical in
Europe. He says cataloging Dow’s 7000 chemicals is a
huge effort, but they don’t have a choice.

“You need to comply; otherwise you cannot sell them
anymore in the European Union.”

There are a half billion consumers in the EU and Dow wants to keep them. Dow and other
manufacturers might have to reformulate – or even abandon
some chemicals if the EU decides they’re unsafe.

While the U.S. is not considering a comprehensive chemical
review like Europe’s new laws, about 30 states are
considering new regulations on chemicals in toys. The Toy
Industry Association doesn’t want a patchwork of laws, so
it’s called for national toy safety standards.

Recently there’s been a big concern about bisphenol-A, or BPA, in some plastics. Some plastic baby bottles
and some water bottles have been pulled from the shelf by retailers. Grist is an online environmental news
outlet. The journalists at Grist have been looking at the BPA issue for a few years. We got a chance to talk
with Sarah Burkhalter at Grist about BPA and why it’s suddenly in the news:

Sarah Burkhalter: “BPA has been in our bottles for a long time, and there have just been some
more high-profile studies in the last year. Back in February 2007, the National Institutes of Health
came out with a report saying that there was a link to BPA and health problems. Even at that point,
people were switching over to glass baby bottles and things like that. But just in the same week,
there was another National Institutes of Health high-profile report, just a few days separate from
when Health Canada – the Canadian Health Department – also expressed concern. So, I just think
it was in the news, and people are suddenly realizing that this is a problem.”

Lester Graham: “So, it was a one-two hit in the media, plus when you mention baby bottles, or
possibly the liners of formula cans, that gets people a little nervous, if there’s something toxic in
that stuff.”

Burkhalter: “Absolutely. And, the thing with BPA is that it’s an endocrine disrupter, it can mimic
estrogen. And so the plastics industry has been saying, ‘well, we use it in such small amounts, no,
it’s no problem’. Other studies have said that even in very, very small amounts, BPA can sneak in
and change cell structure, and really muck-up the reproductive system. And it’s been linked to
early puberty, and breast cancer, and behavioral disorders, and all kinds of things. So when they
hear about this being in, you know, things that we’re regularly eating and drinking from, they pay
attention.”

Graham: “Now, here’s the big question – we’ve seen retailers pull some bottles off of the shelves,
there’s been this controversy with Nalgene, and now even a lawsuit against Nalgene about their
plastic bottles – what plastic bottles are safe to use, what ones can’t I use, how do I tell the
difference?”

Burkhalter: “well, BPA is found in number 7 plastic – that’s also known as polycarbonate or lexan –
and that’s the clear, hard plastic. So Nalgene bottles – not the white ones – but the brightly
colored, clear ones. Those are number 7. There’s also, as you mentioned, plastic adhesive in
linings of cans, some of those, BPA is also in some dental sealants. But when it comes to bottles,
number 7 is the one you want to watch out for when we’re talking about BPA. Number 3 has its
own problems – that’s PVC or vinyl – that’s another one you want to watch out for. If you gotta use
plastic, you’re gonna want to look for numbers 2, 4, and 5.”

Graham: “So we look for those numbers on the bottom of the bottle?”

Burkhalter: “Yup. Those are, I mean, you know, they’re not on every plastic, but if there is a
number on them, its ‘2, 4, and 5 to stay alive’. It’s the rhyme I just made up.”

Phthalate Chemicals Found in Infants

Infants are widely exposed to a class of chemicals that might be harmful to their
reproductive systems. That’s according to new research published today/this week
(Monday, February 4th, 2008) in the journal Pediatrics. Mark Brush reports – the
chemicals are known as phthalates:


Phthalates are everywhere. They’re used to make plastics softer. And they’re used in
perfumes, shampoos, and lotions to help the product absorb into your skin.


Researchers at the University of Washington found that infants had higher concentrations of phthalates in their urine if their mothers used baby lotions, shampoos and powders.
Dr. Sheela Sathyanarayana led the study. She says it can be hard to avoid phthalates:


“In terms of personal care products and cosmetics, we don’t know. The products are not
labeled to contain phthalates in them, and so it’s very, very difficult to kind of counsel
families about what to do.”


Sathyanarayana says more study is needed to determine human health effects. Animal
studies have shown that the chemicals can change hormone levels, leading to
reproductive problems in males.

Chain restaurants and retailers often test
their latest services and products in Columbus, Ohio
before launching them nationwide. It’s one of the
nation’s big test markets. But ‘going green’ is not
a trend that’s going well. Karen Kasler reports
recycling rates are well below the national average.
But businesses in this key market are beginning to
show more interest:


Columbus often bills itself as the nation’s test market. It’s demographics are seen as a reflection
of the nation as a whole. But this national test market is not at the front of the curve when it
comes recycling and other ‘green practices.’ For example, many companies around the country
have going green in the last few years, but businesses in Columbus are just starting to test the
waters.


John Remy works for SWACO, the Solid Waste Authority of Central Ohio It operates the area’s
landfill. Remy has only recently noticed a sudden jump in the number of calls he’s getting every
day:


“The boss wants the business to go green, and so the employees are left to, how do I go
green? And so they call us and want to know, how do I go green? And how do I do it five
minutes before I called you?”


SWACO advises businesses to audit their waste — to dig into trash cans and dumpsters and see
how much paper, plastic, glass, cardboard, food and other material is there and can be
recycled. Some big corporations were already working on that. Columbus’ Anheuser-Busch
brewery is one of big brewer’s 12 plants nationwide. Plant manager Kevin Lee says “green beer”
is not just a St. Patrick’s Day thing here. He says it’s a way of doing business, from the way the
bottles are labeled:



“The backing off of these labels that are applied onto the Bud Light bottle, we recycle the
backing, and there was approximately 66,000 miles of backing a year that is plastic
backing that’s recycled.”


To the cans that fall off the filling lines and end up in hoppers:


“And we send those cans back to a recycling area where the cans are crushed, they’re
sent for aluminum recycling purposes…”


Lee says the idea is to save money and cut down on trash:


“Everything that is consumed off the line, whether it’s the waste beer or the
waste cans or the waste bottles or cardboard, we want to take those materials, treat them
or recycle them, so that we reduce our demand on the environment certainly, reduce our
costs, and that allows us to be the most responsible manufacturer we can be.”


Multi-million dollar automated operations can afford to smoothly snap new green technology
into their production lines, but it’s a little more hands-on in smaller companies and in non-profit
organizations.


Catholic priest David Gwinner did things the old-fashioned way at St. Paul’s parish just north of
Columbus. He stands by one of two eight-cubic-yard recycling bins outside the church offices.
And he says he started by sorting the trash on his own:


“Many days I would take the recycling, separate it and take it in my car.
Yes, in my Oldsmobile sitting over there and my dog, Margaret. And it started to be two,
three trips a day.”


After a few months of dumpster diving, Gwinner decided to organize the St. Paul’s staff in a
recycling effort. In the last year, Gwinner says everyone has gotten in on it – workers in the
administrative offices, guests in the meeting rooms, and the thousand kids in the school. Now,
the trash dumpsters are emptied three times a week instead of every day, which Gwinner says
has saved the parish 2,400 dollars over the last year. But Gwinner says it’s about more
than money. He’s preaching that this is a “partnership with creation,” and now his mission is to
get that message out to his 12,000 parishioners, many of whom own businesses:


“And if they had one or two or three pounds a day, times 12,000, times 365 days a year.
That tells the story of how huge… it’s a million tons a year that SWACO is receiving that’s
going into the ground. And they believe that a great percent of that is recyclable.”


A study a few years ago concluded 60 percent of commercial and residential trash is
recyclable, with paper and plastics the most common things thrown away. But even as
businesses are trying to take their bottom lines to zero when it comes to waste, their employees
may not be taking that attitude home. 88 percent of people in this test market town don’t
recycle. That number is nearly four times the stat from a recent Harris poll which shows the
national non-recycling average is 23 percent.

A new study finds low doses of a chemical used in plastics increases developmental
defects in mice. Rebecca Williams reports the study adds to the growing body of
research that has some scientists wondering if there are human health effects:


The chemical’s called bisphenol A. It’s used to make everything from plastic baby bottles
to the lining of food cans.


The researchers exposed pregnant mice to the chemical. They found that the female
babies those mice were carrying were more likely to have eggs with chromosome defects.
So it’s a three-generational effect. Exposure in the pregnant female mouse increases the
likelihood her grandchildren will have defects.


Patricia Hunt is an author of the study, published in the Public Library of Science
Genetics. She notes this is an animal study and humans are more complex:


“But we also need to bear in mind that this is one chemical of many that have these
effects, they can mimic the actions of hormones in the body.”


Hunt says there’s a growing level of concern among scientists that the developing fetus
might be especially sensitive to chemicals that mimic hormones.

Groundwater Study Finds Low Voc’s

Federal researchers have detected Volatile Organic Compounds, or
VOC’s, in many of the nation’s underground drinking water supplies. But
the samples showed lower concentrations of the cancer-causing
chemicals than some suspected. The GLRC’s Erin Toner reports:


Volatile Organic Compounds are by-products of industrial and
commercial applications. They come from plastics, paints, dry-cleaning
products and gasoline.


Over the past few decades, researchers have detected many places in the
country where soil and groundwater is highly contaminated by VOCs.
This latest study by the U.S Geological Survey took a broader look at
VOC concentrations in the nation’s groundwater.


John Zogorski led the project.


“In most of the wells that we sampled, and we’re sampling before any
treatment by the water utilities, we didn’t find any of these 55
compounds using even our most sensitive analytical methodology.”


Zogorski says VOC’s were found in some drinking water wells, but he
says the good news is that where the VOC’s were found, they were
mostly below federal drinking water standards.
