The next time you’re near your cupboard, check for kosher food items.
The packages have specials symbols, like a “U” or a “K” with a circle around it.
The kosher label shows Jewish people the food was prepared with ingredients that meet religious guidelines.
Shawn Allee learned rabbis had to work overtime to keep kosher food separate from the byproduct of an alternative fuel.

The world of futuristic alternative fuels got tangled up in ancient Hebrew food laws.
To understand how, I talk with a rabbi in the know … Sholem Fishbane of Chicago’s Rabbinical Council.

To start, I admit I don’t understand the key word: ‘Kashrut’ in Hebrew … or ‘kosher’ in English.

“How about your Yiddish?”

“Not so good.”

“Not so good, OK.”

“The word kosher means straight, correct. So when it comes to consumer items, and especially food, how does this play out?”

“The basic concept is that you are what you eat. You become the character of what you’re consuming.”

For example, in the Hebrew Bible, pigs are unclean, so pork’s not kosher.
But even some ‘clean’ foods are not kosher if you mix ’em …

“A very big thing in kosher is not to eat, uh … milk and meat together. meat representing death. milk representing life. Those are things that shouldn’t be coming together.”

So, you separate kosher food foods from non-kosher foods and even each other at times.

Well, Rabbi Fishbane’s job is to keep all this straight at big food factories.
He inspects food equipment and ingredients.

If everything’s kosher, he lets factories use the little “K” character on packages.

So, a few years ago, Rabbi Fishbane was at this factory, inspecting paperwork.

“All of a sudden you see an increase amount of glycerin receipts and hey, what’s going on? You usually have X amount a month and now it’s tripled.”

Glycerin is a common food ingredient, so Rabbi Fishbane thought, ‘no big deal.’
Until … he saw glycerin prices plummet, and his factories substituted it for more expensive ingredients.

“This is now a pattern. When we see a pattern, that’s when we get nervous.”

So, Rabbi Fishbane dialed up a teleconference with other rabbis.

They noticed the same thing … loads of cheap glycerin hitting the market.
The rabbis started sweating.

“glycerin has always been a kosher-sensitive item.”

This is one of the other rabbis on that conference call – Abraham Juravel of the Orthodox Union.

Glycerin keeps food sweet or moist.

It’s a clear, slick goo … and it’s made from oil or fat.

“The fat can be from animal or that fat can be from vegetable. and so automatically, there’s kosher glycerin and non-kosher glycerin. As a food ingredient it’s very common in all kinds of products. They actually use glycerin as a sweetener in certain candies.”

Rabbi Juravel started tracking down the source for all this new glycerin.
After some detective work, he found it was coming from factories that make biodiesel.

Biodiesel is an alternative fuel made from oil or fat.

You chemically process the fat … and you get fuel for cars and trucks, but …

“What you’ll also get is very crude glycerine, which is the waste product.”

Several years ago, new biodiesel factories were popping up and they looked for whatever fat they could find … kosher or otherwise.

“So, they buy used oil that you fried french fries in, and who knows what else you fried in there. if you made french fries and then you also made southern fried chicken in that oil, then that oil’s not kosher.”

Again, if the oil’s not kosher … neither is the glycerin and whatever food glycerin goes into.

There is a happy ending here.

Rabbis worked overtime to keep non-kosher glycerin out of the kosher food supply, but they actually made biodiesel operations part of the solution.

Some factories switched to all-kosher oils, so now their waste guarantees a steady supply of religiously pure, kosher glycerin.

Coal Ash Controversy

This past December a sludge of coal ash broke out of an impoundment at a power plant in
Tennessee. It destroyed homes. It devastated a section of river. And it set off a firestorm
about the problem of coal ash disposal. Now two US Senators and a bunch of environmental
groups are calling on the Environmental Protection Agency to regulate coal ash. Tamara
Keith has the story:

Coal ash is byproduct produced by coal burning power plants and it’s stored at more than 500
sites around the country.

Anti-coal activist Dave Cooper signed onto a letter this week with more than 100
environmental groups telling the EPA it’s time to get involved.

“What we want is for the EPA to regulate coal ash as a hazardous waste.”

But Dave Goss with the American Coal Ash Association says safe storage is an issue, but a
lot of the ash is actually recycled into things like concrete and wallboard.

“If you stigmatize it by giving it some sort of a classification such as hazardous, that’s going
to have a dramatic impact on the ability to re-use the materials.”

The EPA has been studying this issue for years, and hasn’t responded to the latest calls for
regulation.

Capturing Wasted Methane From Landfills

  • A landfill is full of things people don't consider useful anymore. One group begs to differ. (Photo by Roberto Burgos S.)

The landfill is often seen as the end of the line… the burial ground of our trash. But one company says there’s still something to gain from that buried garbage.

The landfill is often seen as the end of the line… the burial ground of our
trash. But one company says there’s still something to gain from that buried
garbage. It’s planning to build a new plant to retrieve one final product from
all of our trash. The Great Lakes Radio Consortium’s Karen Kasler has the
story:


You probably don’t think of landfills as “green.” But Steve Wilburn does.
Wilburn is the president of FirmGreen. He says he knows different ways to
turn byproducts of landfills into useful energy.


First, capture the methane that’s produced when all that garbage stews
underground. Second, use it as fuel to generate electricity. Third, turn it into compressed gas for trucks. And finally, mix
it with soybean oil to make soy diesel.


Steve Wilburn says it’s an ambitious project.


“This is the first of its kind in the world. The Green Energy Center concept is
something I came up with about four years ago, and as we explored for ways to
implement it, we needed a centerpiece, a technology that was missing, and that
was to clean up the landfill gas in a very cost-effective way.”


FirmGreen is building what it calls its Green Energy Center right next to the
landfill in Columbus, Ohio. Mike Long is with the Solid Waste Authority of Central Ohio – SWACO for short. Long says right
now, there’s no practical use for the methane and carbon dioxide produced by the rotting garbage in the landfill.


“Currently, SWACO’s control technology is to have a flare where we burn off the
gases to keep it from getting up into the atmosphere. But the new technology,
we will take that gas and make it into energy and consumer products rather than
just simply burning it and exhausting it.”


Instead of burning those landfill gases, they’ll be redirected a small
electric generator operated by FirmGreen. The electricity will be sold back to
SWACO to power its main office and its fleet garage. That’ll start in just a
few months.


Later, FirmGreen will convert methane into compressed natural gas. That will
be used to fuel SWACO’s vehicles, which could save the waste authority an
estimated 100 thousand dollars a year.


FirmGreen’s President, Steve Wilburn says the final part of the project is the
real profit maker for his company: turning methanol into biodiesel.


“When we create
methanol, we then have the bridge to the hydrogen economy because ethanol is an
excellent hydrogen carrier. It’s also used in the manufacture and production of
biodiesel. Ohio is a large soybean producing state. So we’ll take our green
methanol and we’ll blend that with the soy oil and we’re going to create
biodiesel.”


When the FirmGreen biodiesel processing facility is up and running, it will
need 69 thousand acres of soybeans to produce 10 million gallons of biodiesel
annually. FirmGreen already has a contract with Mitsubishi Gas Chemical
Company to provide 6 million gallons of biodiesel a year. FirmGreen also hopes
to interest the growing hydrogen fuel cell industry.


“Biofuels” have their critics, who are concerned that it takes as much energy
or more energy to create biofuels than they produce. Mike Long at SWACO says
he’s heard that before, but it doesn’t apply to this project.


“The
energy is already here, and is being flared off right now at our landfill. There’s no recovery of the energy, no beneficial
use. So for those who argue that this process would be a consumer of energy, it’s not a net consumer, and right now, we’re wasting energy.”


Long and Wilburn point to statistics from the U.S. EPA. They says the data show
the Green Energy Center will have the same effect as reducing oil consumption by
more than twenty thousand barrels a year. They say that’s like taking 2,000 cars off the road.


Sam Spofforth is with the Central Ohio Clean Fuels Coalition. He says even
when factoring in the fuel used by trucks transporting the methanol to the
remote biodiesel processing facilities, the project still looks green to him.


“In terms of biodiesel, it’s about three point two energy units out for every one energy
unit in. What is even more exciting about this project – methane
gas is about twenty times as potent as a greenhouse gas as carbon dioxide. So the
fact that they’re using methane that would otherwise be vented into the air
makes the net emissions of those greenhouse gas even more positive.”


The Green Energy Center in Ohio is the first in the nation, but a second one
is planned to be built near Saint Louis, Missouri. With giant landfills venting
off methane in places around the country, if these two make money, it’s a
pretty sure bet others will be built in the near future.
