States are considering laws to phase out a material used in brake pads on cars and trucks. Lester Graham reports… it’s contributing to water pollution that’s affecting fish.

There’s a fair amount of copper in brake pads. Every time you put on the brakes… some of brake pad and the copper in it is worn off. It ends up on the pavement and eventually is washed into a stream or lake. That’s been causing some concern in the state of Washington where too much copper is hurting the salmon. A new state law bans heavy metals in brakes and requires phasing out copper.
Curt Augustine is with the Alliance of Automobile Manufacturers. He says they worked with lawmakers and environmentalists to come up with the plan. Other states might adopt it.

“Bills have been introduced in California and Rhode Island and likely similar bills will end up in some of the Great Lakes and Chesapeake Bay states.”

The Washington law calls for brakes to contain no more than five percent copper by 2021 and then consider using even less in later years.

Biodiesel Gets Lost in the Shuffle

Biofuels made from corn and soybeans have been bi-partisan political favorites in Washington for years, but Shawn Allee reports, one biofuel’s in political trouble right now.

Biodiesel’s made from soybean oil.
It usually gets a one-dollar per gallon federal tax credit, but that expired in December.
Since then, biodiesel makers have been laying off workers.
Alan Yoder manages Iowa Renewable Energy.
Yoder says he’s puzzled Congress has not renewed the biodiesel tax credit especially since other alternative energy sources still get help:

“A lot of alternative fuel projects they’re talking about are really still in the research stage. Biodiesel is on main street. It’s working and there’s production, there’s people using it, people employed. This is big stuff.”

A biodiesel trade group claims the industry’s laid off 22,000 workers.

Congressional aides say there’s support for renewing the biodiesel tax credit, but it got lost in the shuffle during debates on health care and new stimulus spending.

Energy analysts say a glut of
oil means gas prices probably
won’t spike too much this year.
Rebecca Williams has more:

We’re paying anywhere from 70 cents to a dollar more per gallon than this time a year ago. The good news is, we’re not likely to see four dollar-a-gallon gas anytime soon.

“We’re not in a world with runaway oil prices.”

That’s Ruchir Kadakia. He’s a global oil market expert with IHS Cambridge Energy Research Associates. He says weak global demand is keeping oil prices in check for now. At the same time, supply is relatively high. He predicts oil won’t average much higher than 80 dollars a barrel for the next year or so.

“And so what that really means for the gasoline point is through probably 2011, we shouldn’t expect to see gasoline prices much above three dollars unless it’s for a short period of time maybe in the summertime for a few months.”


Kadakia says oil speculators can drive prices higher or lower in the short term. But he doesn’t think we’ll see any major price spikes over the long term.

The US government is steadily
increasing the amount of ethanol
used in our gasoline supply.
But Shawn Allee reports
that effort’s hit a roadblock
in the country’s largest gasoline
market:

California regulators want car fuels to come from sources that create fewer greenhouse gas emissions. That means corn-based ethanol will soon get a kind of penalty in California’s fuel market.

Environmental groups like the Natural Resources Defense Council say ethanol should be at a disadvantage. The NRDC’s Roland Hwang says when we grow corn for fuel, farmers overseas plant more corn.

“Someone’s going to cut down a rain forest or convert pasture land or grass land to grow more food. Unfortunately, converting that land will lead to very dramatic increases in global warming pollution.”

Hwang wants the ethanol industry to stop using food crops for fuel.

Ethanol makers are not taking California’s rules sitting down, though; they’ve gone to court. They argue more lenient federal rules on ethanol should trump California’s.

US dropped in 2009. Lester
Graham reports that’s the first
time that’s happened since
World War II:

Last year there were four million fewer cars, but two million more drivers than in 2008.

Lester Brown is with the Earth Policy Institute. His group reviewed the numbers. He says the market’s saturated.

“We have more licensed vehicles than we have licensed drivers. So, we couldn’t get all our cars on the road at once if we wanted to because we don’t have enough drivers. That’s one way to define saturation.”

The Earth Policy Institute also found more people have access to mass transit, people are concerned about the impact of foreign oil, gasoline prices, and young people socialize on the internet and cell phones more than driving around in the car with their friends.

Auto industry experts say the decline of cars on the road has more to do with tight credit for auto loans than anything else.

New car models are hitting the

efficient cars are selling in the
wake of the government’s Cash-
for-Clunkers program:

It’s hard to miss the ads for new models.

(montage of car advertisements)

But in September, fuel-efficient cars didn’t sell that well.

Mark Gillies is the Executive Editor for Car and Driver magazine. He says vehicles that get good gas mileage probably won’t start selling until gasoline prices go up – just like last year.


“That’s when you saw a big move to buying more fuel efficient vehicles. And I think the obvious thing about oil prices is that long term the trend is that they’re going to go up and they’re going to stay that way.”

Fuel-efficient models did sell in August because of Cash-for Clunkers, but Gillies says people bought low-end models this time because they were cheap – not necessarily because they were fuel-efficient.

The Attractiveness of Ethanol

Cheap oil makes switching to alternative
fuels such as ethanol less attractive.
Lester Graham reports that could affect
an upcoming decision about using more
ethanol:

Crude oil prices spiked a little because of Iran’s long-range missile testing and revelations of a secret nuclear facility.

But analysts think for the next several months we’ll actually see oil prices go down – maybe to around $30 a barrel, less than half of what it is now.

And that could hurt demand for fuels such as ethanol.

But the government has mandated the nation produce more ethanol.

Dan Flynn is an analyst with the trading firm, Alaron.

“Obviously the government definitely wants to push this through. However, the price of crude oil and gasoline, if that goes down, generally people look not to look for alternative sources of energy.”

One way to use more ethanol is to mix higher amounts with gasoline.

The government will soon decide whether to allow increasing the mix from the current 10% blend to as high as a 15% blend.

Sampling a New Crop: Sugar Corn

The federal government wants more
and more ethanol in our fuel supplies,
but it worries about how its made.
Most American ethanol is made from
corn kernels. That’s inefficient
and it makes the ethanol and food
industries compete for corn. The
government’s mandating we start making
ethanol out of things other than corn
kernels. Shawn Allee looks
at one effort to meet that mandate:

I’m just outside an ethanol plant in central Indiana and its pretty much like most ethanol
plants. There’re a lot of semi-trucks going by and they’re loaded with yellow corn kernels.


Most ethanol plants grind corn kernels for starch, they let that starch turn into sugar, then
they brew the sugary juice into ethanol. Now, this whole process would be easier and
cheaper if we could make ethanol directly from sugary plants instead of starchy grain
kernels like corn.


Pretty quick here, I’m gonna meet a guy who’s trying to make corn a plant that’s easy to
grow in the Midwest but produces sweet juice – not starchy corn kernels.

“If you walk over here, these are our sugar corn hybrids.”

I’m with Todd Krone. He’s a researcher with a company called Targeted Growth. He walks me
through a test plot of a plant nicknamed ‘Sugarcorn.’ He pulls off a ear of corn and pulls back the
leaves.

(sound of leaves being pulled back)

The ear is almost bare.

Allee: “There’re just a few stray kernels developing, very few.”

Krone: “Yep. A few got through.”

Krone says this plant avoids making corn kernels. Instead, it puts energy and sugar into the
stalk. He can prove it with a taste test – right here in field.

He snips a piece of stalk.

(sound of snipping)

And pulls out a little press.

Krone: “You squeeze some of the juice to see how much sugar’s there. It’s up to you, if
you like, you could put on on your finger and taste. Is there sweetness?”

Allee: “Yeah, it’s definitely sweet. It’s definitely got a sweet tinge to it.”

Krone: “It might be a bit sweeter than pop might be.”

Krone says tests show Sugarcorn juice is as sweet as juice from sugar cane. He says this means
America could have a new plant that boosts ethanol production – but doesn’t compete with food,
and uses equipment farmers already have.

Krone: “For the farmer, not much changes until harvest when some logistics still need to
be worked out.”

Allee: “Obviously if you’re selling a lot of this corn, you’d be making a good deal of profit,
hopefully, what’s in it for the rest of us in terms of the success or failure of this, for drivers
and everybody else?”

Krone: “I would say, hopefully, it results in cheaper ethanol that can compete with cheap
oil. And then meeting that mandate to get more and more ethanol produced.”

Well, that’s the idea, but Targeted Growth would have to change more than just corn plants to
succeed. They’de have to change how at least some ethanol companies do business. And some
ethanol companies have some tough questions about it.

“How could you handle sugarcorn? How would you store it?”

This is Jeff Harts. He works at Central Indiana Ethanol. Harts says he likes the idea of using
sweet corn juice to make ethanol – it could be efficient. But he worries about getting enough to
run an expensive operation like his. He has no problem finding corn kernels.

“It’s a consistent flow of corn and we need that consistent flow to keep going. That’s why
we have storage, the farmers have storage. That’s why we have a local grain elevator
network to ship corn to us to keep that flow steady 12 months out of the year.”

Harts’ company might be a bit reluctant to change right away, but ethanol producers will have
find alternatives to the corn kernel. The government is capping how much ethanol can come
from corn starch.

As those requirements phase in, alternatives like Sugarcorn might look sweeter than they do
now.

Recycling Your Ride

We’ve all heard over and over again about that government program ‘Cash for Clunkers.’ It’s got drivers thinking about what exactly happens to dead cars, regardless of how they die. Shawn Allee looks at how car recycling works and who’s trying to improve it:

You might not think about it this way, but your car just might be the biggest thing you own that gets recycled.

I mean, someday you’re going to junk it, or maybe some future owner will. Anyway, I’m out in front of a car shop in my neighborhood, and with the health of cars in mind, I thought I’d ask some people around here, percentage-wise, just how much of a junked car gets recycled?

“I would say maybe, like, 5% of the car.”

“I’ll say, 20% – 30% probably, of a car.”

“I guess the recycled one could be 30% of the car.”

“I guess, like, 50%.”

“About 70%.”
++

In my little unscientific survey here, it turns out that most people are giving a pretty low estimate of how much of a junked car ends up being recycled.

The auto industry and the federal environmental protection agency say about 80% of the junked car gets recycled. The rest heads to landfills. That sounds pretty good, but that means we bury about five million tons of junked car pieces each year.

To understand why they can’t recycle even more of the car, I’m going to talk with Jim Watson.

He runs ABC Auto Wreckers in a suburb just south of Chicago.

“We don’t want to landfill anything. The objective is to take the vehicle, process it and have all the parts be used.”

Watson shows me his shop where he pulls parts for the used market. A dozen workers lift hoods, twist tires, and pull out stuff I don’t even recognize. It’s like an assembly line in reverse.

“They do an analysis and inventory each of the parts of the car that have a probability of sale and then they harvest or pull those parts off the car.”

Watson and some of the bigger auto wreckers have parts-scrapping down to a science, but it’s expensive to keep pulling parts and keep space open for scrap yards.

Eventually, Watson’s pulls off everything usefull and he’ll send it to a car shredder.

“A machine that beats it apart and shreds the car into small fist-sized or hand-sized components.”

Recyclers can pull out big shreds of steel and aluminum, but about 20% of the car is left-over. This shredder residue gets tossed into landfills. But scientists are thinking about how to recycle this shredded mess.

One works at a lab at Argonne National Laboratory near Chicago.

“This is what shredder residue looks like.”

Dr. Bassam Jody reaches into a cardboard box and scoops a jumble of car seat foam, metal cable, wood, and shards of plastic.

Jody says shredder residue is a recycler’s nightmare.

“Maybe there are more than twenty different kinds of plastics. I tell you, plastics are generally incompatible, they don’t like each other and they don’t work together very well.”

Jody is developing machines to safely clean and separate all this stuff. It’s tough science.

Jody: “The more things you have in the mixture, the harder it is to separate. The trick is, you have to do it economically, and to produce materials that can be used in value-added products.”

Allee: “What can you make out of them?”

Jody: “Car parts. For example, this is a seating column cover.”

Jody says he gets a kick out of his work. He might just squeeze a bit more good out of our cars.

Turning Clunkers Into New Cars

All those clunkers are working their
way toward the final melt-down at
a steel mill. Lester Graham reports
you’ll see the steel from those clunkers
again:

The steel from those clunkers from the “Cash for Clunkers” program will eventually be melted down and used again.

Bill Heenan is the President of the Steel Recycling Institute. He says it’ll be a few months before that scrap gets recycled.

“It takes some time for that old automobile, the clunker in this particular case, to work its way through the dismantling system and then through the shredding system and eventually to the steel mill.”

Scrap yards can remove things such as fenders or hubcaps for used parts, but what’s left – including the engines – goes to the shredder.

Bill Heenan says those 700,000 clunkers won’t mean a glut of scrap steel.

“Let’s say there’s a ton of steel in each one, you’ve got 700,000 tons. That seems like a lot. But in a given year, we recycle 80-million tons.”

That 80-million tons of scrap is melted down and becomes the bulk of new steel products in the U.S., including new cars.
