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.

Building for Disasters

There’s a whole category of disasters people think will probably never happen to them. Major floods, landslides, and earthquakes happen sometimes decades or centuries apart. So, people don’t think about them or they ignore the risks. And, some experts say, that’s why we build or buy houses in places that really aren’t safe. The Great Lakes Radio Consortium’s Melissa Ingells reports:


Disasters happen. It’s only a matter of when. The problem is, we prepare for things like tornadoes that happen every year, but we aren’t prepared for a major flood that might only happen once a century. Donald Hyndman is with the Department of Geology at the University of Montana. He’s an expert on disasters.


“People just do not understand the scale of events, they also don’t understand that if in their lifetime there hasn’t been a really major event, that there won’t be a really major event.”


So Hyndman has co-written a new textbook on disasters. He says there’s a lot of pressure to build houses in places that are hazardous. Maybe it’s just a great view, so people build there despite warnings. Or, they think they can stop the ground from moving with retaining walls, or think they can stop floods using levees. Donald Hyndman says that even well built projects just can’t stand the power of nature.


“There is increasing pressure to build in the same lowlands, the same flood plain areas, and the developers say, well, the Army Corps of Engineers has built a major levee or dyke here, that protects people on these floodplains. The problem is, levees break and they always break.”


Donald Hyndman’s co-author is his son, David Hyndman, a geologist from Michigan State University. David Hyndman, says even when a place is a known area for disasters, demand for housing means buildings go up all over again in the same spot.


“There’s always development pressure, and the developers even fairly soon after large floods like some that occurred in California, they keep pushing and the public has forgotten what has occurred and then often the development will be allowed, which causes a disaster afterwards.”


Donald and David Hyndman both say developers don’t help the situation when they build in dangerous areas.


But folks in the housing business say there are plenty of laws to warn potential homeowners, before a house is even built. Lynn Egbert is the CEO of the Michigan Association of Homebuilders. He says that people often ignore the regulations because they want to live where they want to live.


“Consumer desire – consumer interest and desire is the primary reason, even though there are state regulations and federal regulations to put people on notice and protect against the risk for insurance, to locate where they want to locate, which is a property right.”


Egbert says that real estate people and lenders are supposed to let property owners know of the risks. Sometimes that happens. Sometimes people don’t know to ask. And sometimes people think that despite the risks, a disaster just won’t happen to them. Donald Hyndman says we don’t respect how powerful the earth really is.


“Basically, some people feel that they can control nature, or improve on nature, and I’ve actually heard some politicians say we can improve on nature. We can not only not affect the results, those results are typically – they typically backfire. So we really cannot control nature.”


The Hyndmans are hoping their new textbook will help build awareness of all kinds of disasters—but especially the ones that could happen right in our own backyard.
