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.

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.

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.

Returning Quality Food to Urban Areas

Finding a big supermarket is next to impossible in many inner-city neighborhoods. That means a lot of people do their shopping at convenience and liquor stores, where there’s rarely fresh produce. The Great Lakes Radio Consortium’s Sarah Hulett reports on one group’s efforts to get around the grocery store problem and help revitalize a neighborhood:


(Sound of traffic)


Up and down this street as far as the eye can see are crumbling and burned-out buildings. This used to be a thriving business district. It’s where Vlasic Pickle, White Owl Cigar, and Lay’s Potato Chips grew into national brands. Today, the most evident sign of commerce is the prostitutes walking the street. Smack in the middle of this is Peacemaker’s International. It’s a storefront church where Ralph King is a member.


“Now if you look at it you see that there’s no commercial activity, no grocery stores within a mile of here. And our concern was that people had to eat.”


There are about seven liquor stores for every grocery store here on the east side of Detroit. Some people can drive to the well-stocked supermarkets in the suburbs, but many families don’t have cars, and King says the city busses are spotty.


“So they’re buying food at convenience stores or gas stations. And quite frankly, it just doesn’t seem a good fit that a community has to live off gas station food.”


That means processed, high-starch, high-fat diets that lead to illnesses like heart disease, diabetes, and high blood pressure. Those are all problems that disproportionately hit African Americans, and public health researchers say those higher rates of illnesses are linked to the food availability problems in poor black communities.


Amy Schulz is with the University of Michigan, and she’s studied the lack of grocery stores in high-poverty neighborhoods.


“What we found, in addition to the economic dimension was that Detroit, neighborhoods like the east side that are disproportionately African American are doubly disadvantaged in a sense. Residents in those communities have to drive longer, farther distances to access a grocery store than residents of a comparable economic community with a more diverse racial composition.”


In other words, if you’re poor and white, you have a better chance of living near a grocery store than if you’re poor and black. Ralph King and the folks in this neighborhood want to get around that problem. So about three years ago, they decided to try and reopen a nearby farmer’s market. They turned to Michigan State University Extension for help. Mike Score is an extension agent.


“I thought it would just be the process of organizing some people, helping them buy some produce wholesale, setting up in the neighborhood, selling the food, and generating a net income that could be reinvested. And I was really wrong.”


The farmer’s market was a flop. Score says produce vendors set up in the neighborhood, but the fruits and vegetables sat all day, unsold. He says the problem was they were using the wrong currency. Most people in this neighborhood have very little cash on hand, and they need to use their food stamp cards to shop for groceries.


So, Score helped develop a plan for a neighborhood buyers’ club that can negotiate low prices by ordering in bulk. His business plan also calls for job training for people in the neighborhood.


“It’s going to give people who are chronically unemployed but who have some entrepreneurial skills access to food at a lower cost, and that enables them to think about starting restaurant businesses or smaller retail businesses. So that’s an important part of this project: in addition to getting people groceries, it also creates some job opportunities.”


It’s been a struggle to get the program off the ground. It took a long time to get approval from the U.S. Department of Agriculture for a machine to read peoples’ food stamp cards. People have stolen some of the project’s meager resources, but Mike Score and Ralph King say they’ll stick with it until families in this neighborhood can put decent food on their tables. And they say they hope it can be a model that other low-income communities around the country can use.
