This winter U.S. automakers have unveiled more environmentally friendly cars, SUVs, and
trucks. They include gas-electric hybrids, even hydrogen fuel cell powered vehicles. The new
models will reduce smog and other emissions and reduce our dependence on foreign oil. But a
cleaner domestic fuel already exists for diesel cars and trucks, and you can find it at most
restaurants. The Great Lakes Radio Consortium’s David Sommerstein profiles a man who brews
his own biodiesel from used vegetable oil:


Joe Rappa’s VolkSwagen Quantum looks like any older car. It’s a maroon station wagon with
180,000 miles on it. It’s got a diesel engine with the tell-tale diesel rattle.

But even though we’re inside an enclosed garage in an auto lab, there’s no black exhaust, no acrid
diesel smell. Instead, it smells like a kitchen.


“Some people say it smells like French Fries, some say it smells more like hamburgers on the
grill than anything else. But everyone smells something different with biodiesel.”


Rappa teaches automotive courses here at the State University of New York in Canton. He lives
120 miles away. Several times a week he commutes in this car powered by biodiesel – a fuel
made from used vegetable oil he collects from local restaurants. He says anyone with a diesel car
can do it themselves.


“It might be a bit unnerving at first because we’re so conditioned to put the same fuel in our car,
that y’know that you go make something in your garage and then go pour it in the tank of your
car goes against everything you’ve been ever taught for the last 20 years that you’ve been
driving.”


Joe Rappa has a mischievous smile when he talks about brewing his own fuel, especially with
most people worrying about the price of gas, the places our oil comes from, and what it does to
politics and the environment. But Rappa insists he’s not an environmentalist.


“I don’t consider myself a big polluter, either. I’m a tinkerer. I always have to fool around with
something. It’s funny, my dad always used to kid me from the time I was a little kid, ‘You’re not
happy unless you’re screwing around with something.’ My bicycle worked fine, I’d take it apart.”


As an adult, he bought a diesel car. One day, he started reading about biodiesel on the Internet.


“And the more I looked at it, the more I thought, that’s kind of silly, but I bet I could do that, and
got a hold of the chemicals and started fooling around and making mini-batches, and once I was
confident the mini-batches were actually biodiesel and something I can burn in an engine, I
started making bigger batches and putting the stuff in my car.”


Today Rappa spends Sundays in his garage brewing up to 120 gallons of it at a time. He’s
considered a leading expert on biodiesel bulletin boards on the Internet.


Most of the enthusiasts he e-mails with are environmentalists. They see biodiesel as a way to
reduce our reliance on foreign oil and clean up the choking exhaust cars and trucks belch out their
tailpipes. Rappa says biodiesel creates less than half the smog-causing emissions of regular
diesel.


“The particle emissions out of the tailpipe, 70% less simply by switching fuel, 70-80% less
hydrocarbon, 70-80% less carbon monoxide, those are some serious numbers.”


Nitrous oxide levels are a little higher, though. Those also contribute to smog. But for Rappa,
the big number is price. It costs him 54-cents a gallon to brew the stuff.


Rappa snaps on rubber gloves to show me how it’s done. Basically you mix methanol and lye to
make methoxide. Then you add the methoxide to the oil. The ratio depends on the amount of
animal fat in the vegetable oil, which you figure out through what’s called a titration, and the
amount of biodiesel you want to brew.


“Now we just add the methoxide to the vegetable oil.”


Rappa uses old Pepsi bottles for this demonstration and a wine carafe to hold the oil.


“Put our lid on there. Give it a shake. Immediately it turns to a milkshake consistency. And the
reaction only takes a couple seconds to take place. You mix it thoroughly and it’ll start to get
dark as my biodiesel starts to form.”


The result is honey-colored biodiesel. Glycerine – basically soap – settles on the bottom as a by-
product. Rappa cautions this takes practice. You have to boil the vegetable oil to remove any
water in it. You need to make sure you separate the biodiesel from the glycerine.


In fact, most people who use biodiesel in their cars buy it commercially. Their number is
growing. The National Biodiesel Board predicts biodiesel production will increase by 20 million
gallons this year. Most it is made from soybeans. Some producers use other vegetable oils. But
a U.S. Energy Department-funded study says there’s enough used vegetable oil and other waste
grease to produce 500 million gallons of biodiesel each year.


(sound up of driving)


That’s plenty to keep Joe Rappa’s car on the road and encourage others to join him.


“I still chuckle every time I pour in fuel I made in my garage in the tank of my car.”

Carmakers Exempt From Greenhouse Gas Plan

The Canadian government is under attack by environmentalists after it exempted car
manufacturers from its plan to reduce greenhouse gas emissions. The Great Lakes Radio
Consortium’s Karen Kelly reports:


Opponents say the government granted the exemption because the car assembly plants are located
in Ontario.


The province is a stronghold of support for the leading Liberal party.


But federal officials say the auto plants were exempted because their emissions are already low.


Many industries are required to reduce their greenhouse gas emissions under the newly signed
Kyoto Protocol on climate change.


John Bennett of the Sierra Club agrees that the auto plants are relatively small polluters.


But he’s concerned that the feds lost some leverage as they try to convince automakers to create
more fuel efficient cars.


“It was a short term political tactic, but in the long term, it might mean we won’t get the kinds of
fuel efficiency improvements in cars that are absolutely essential if we’re going to meet the Kyoto
target and go beyond it.”


Thus far, the auto industry is resistant to building more efficient vehicles.

Pay-Per-Mile Insurance a Fairer Option?

An environmental group is calling for a change in how we pay for car insurance. The Great Lakes Radio Consortium’s Lester Graham reports on the group’s strategy to lower rates for people who drive their cars less:

An environmental group is calling for a change in how we pay for car insurance. The Great
Lakes Radio Consortium’s Lester Graham reports on the group’s strategy to lower rates for
people who drive their cars less:


The group, Environmental Defense, wants it to work this way: if you don’t drive your car that
much because you’re taking the bike, or walking, or using mass transit, then you should be
allowed to pay for insurance based on the miles you drive. Michael Replogle is the
Transportation Director for Environmental Defense:


“Those of us who drive less are helping to protect the environment, but we’re paying a
disproportionate share for car insurance. We pay a much higher rate per mile than those who
drive more.


The flip side of it is, to work, everyone would have to be charged on a per mile basis.
Environmental Defense thinks that would be a step toward cutting down how much all of us
drive, burn up gasoline, and pollute. The group says it’s talking with a couple of insurance
companies that are studying the idea.

‘ODOR PATROL’ SNIFFS OUT POLLUTION

The world’s largest automaker is doing something it’s never done before. General Motors is recruiting people who live near its assembly plants to help the company find ways to pollute less.

The world’s largest automaker is doing something it’s never done before. General Motors is
recruiting people who live near its assembly plants to help the company find ways to pollute less.
But as the Great Lakes Radio Consortium’s Erin Toner reports, some environmentalists say GM’s
efforts are missing the point.


The city of Lansing, Michigan is the car Capital of North America, producing nearly a
half-a-million Pontiacs, Oldsmobiles, Chevrolets and Cadillacs every year. Later this year,
General Motors adds another car to its Lansing lineup – a brand-new Chevy roadster. But it
almost didn’t happen.


Environmentalists threatened legal action to block production because they weren’t satisfied with
the factory’s air pollution controls.


Steve Tomaszewski is General Motors’ Lansing environmental manager.


“People were concerned, everyone was concerned. There was a breakdown of communications,
on all parties.”


The disagreement was over air pollution from one of GM’s plants. Those emissions were due to
nearly double under a new state air quality permit.


Some Lansing residents and two state environmental groups threatened to appeal that new permit
if GM didn’t agree to use better pollution controls. The two sides made their cases in the local
papers and eventually struck a deal.


Again, GM’s Steve Tomaszewski.


“We’ve come a long way, a long way, from where we started in the process. You know, we sit
down and we know more about people’s families other than just concentrating, on you know, the
industrial odor issues, which is great.”


General Motors agreed to join a new Air Quality Task Force. It’s made up of GM engineers,
environmental officials and people who live near the plants. GM also brought in an odor expert to
train the group to sniff out emissions from the plants’ paint shops. This “odor patrol” then files
reports to a new Web site.


Marci Alling is part of the group.


“They kind of calibrated our noses, that’s about the best way to describe it to kind of get us all
where we are more or less reporting the same levels of odor.”


Alling and her husband have lived near GM factories for 10 years. Often, whether they spend
time in their backyard depends on which way the wind blows. In certain weather conditions,
typically on hot, sticky days, a paint-like smell from the plants drifts through their neighborhood.
They’ve wondered whether the odors are making them sick.


State officials say the odors might be annoying, but recent studies found people who live near the
plants are not at a greater risk of cancer or other illnesses.


GM’s Steve Tomaszewski says the odor patrol will help the automaker better monitor emissions.


“We know we can’t be completely odor free. We strive to do our best. But this information, what
we’ll do is be able to go back and it’s more real time. You’re able to link it to the day and the time,
and we’re able to go back into the process to see what’s happening.”


But environmental groups say General Motors should be doing more to reduce pollution in the
first place, instead of tracking emissions after they become a problem.


James Clift of the Michigan Environmental Council says technology is available to make the
painting process cleaner. But he claims GM isn’t using it.


“If what you need is pollution control equipment and it’s not there, the odors may continue. We
might know better what they are, but if the permit doesn’t require them, it doesn’t matter. Now,
the department always has the ability to bring what they call an odor violation against General
Motors. In my mind, they’ve received lots of complaints over the years, but the DEQ has never
acted and actually issued a violation on odors.”


But the Michigan Department of Environmental Quality says it has issued odor violations against
General Motors. GM was ordered to raise its smokestacks in Lansing a couple of years ago
because of a violation. And GM says it recently spent 4-million-dollars on new painting
technology that greatly cuts down on pollution.


Now, General Motors is counting on its neighbors and their noses to help the company improve
air quality near its factories. GM says the project could lead to better pollution controls at plants
throughout the country, including more than 40 in the Great Lakes region.

Super Unpatriotic Vehicles

Recent reports that sales of SUVs, mini-vans, and light trucks have outstripped car sales has Great Lakes Radio Consortium commentator Don Ogden wondering if SUV is short for Super Unpatriotic Vehicle:

New Emission Control for Diesels

The company that fueled the innovation for cleaner auto exhaust is looking to do the same for diesel-powered trucks and buses. The Great Lakes Radio Consortium’s David Sommerstein reports:

Commentary – The Costs of Comfort

A recent Canadian Government study shows that sports utility vehicles
are responsible for a seven-percent increase in auto emissions. Great
Lakes Radio Consortium commentator Suzanne Elston thinks it’s time
consumers took a second look at the cost of comfort:

Demand Is High for Hybrids

For the first time, demand is high for an environmentally friendly
car. Honda’s new Insight now has a two-month waiting list. The Great
