NCERC’s 20 YEARS of Impact

Two decades after opening—helping the ethanol industry advance as it experienced 12-fold growth—the Southern Illinois research facility is not only proving why it's worth celebrating, but how it can impact the future of biorefining.

The National Corn-to-Ethanol Research Center at Southern Illinois University-Edwardsville turns 20 this year. For two decades, NCERC has been a dependable outlet for entities ranging from multinational corporations to small startups looking to test, validate or improve a component of the ethanol production process. There are several milestone moments that have occurred since NCERC's inception. Hundreds of ex- perts, researchers, tech developers, managers and other personnel across the ethanol industry are have ties to the center. And although NCERC has achieved a status within the industry that warrants a tribute that looks back at what it’s done, this moment doesn’t seem to be only about celebrating the past. As our conversation with John Caupert, executive director of NCERC for all but three years of its existence, shows, the facility’s 20-year anniversary is perhaps more about what NCERC is doing now, and how it can impact ethanol production and corn utilization in the future.

Part of Ethanol’s History and Future

NCERC is roughly 30 minutes from St. Louis. When the International Fuel Ethanol Workshop & Expo (the world’s largest gathering of ethanol producers) would take place in St. Louis, NCERC was almost always a featured stop on the event’s facility tours. Even today, industry professionals not only want to see the latest work being done there, but industry sponsors—companies that support NCERC—enjoy being onsite. At one time, the building may have been considered on-trend. Today, it serves its purpose. The link between industry sponsors/partners and the facility has always been healthy. NCERC receives a mix of state funding, federal dollars and payment from industry partners that use the resources offered in Edwardsville in exchange for a fee. Siemens and Shimadzu Corp., for example, are two major sponsors associated with NCERC and its continual quest to improve fermentation and research.

The facility employs roughly 30 to 40 full-time team members, with interns, guest researchers and others contributing at any given time. The fully-integrated facility has multiple bioreactors and can provide engineering design, method development, process control and automation, doing so with client confidentiality, intellectual property protection and commercialization services. For that, the team at NCERC provides project design, proof of concept, third-party validation and scaleup insight.

Through its fermentation lab, the team can evaluate potential fermentation products at 250mL and 5L. At its fermentation suite, pilot-scale bioreactors at 30, 150 and 1,500 liters are ready. A pilot plant includes four 22,000L anaerobic bioreactors. And, in the analytical lab, high quality data is collected and secured.

When talking with Caupert about what the center can do for the industry, and perhaps specifically fermentation, he says it should be more a question of what the center can’t do.

According to Caupert, in the early days the center did a tremendous amount of collaborative work with the USDA. They were looking at the possible yield of ethanol per bushel of corn. “We wanted to know how many gallons we could get, and we were primarily looking at the conversion of the endosperm or the starch portion of the kernel,” he says.

After that, came a focus on de-oiling of the kernel. They also used to talk a lot about the biorefinery concept. “Today we have a biorefining reality,” Caupert says.

Dry grind ethanol plants are now taking a kernel of corn and producing multiple value streams. That reality has altered some of the work done at the center.

STEPPING UP TO SCALE: NCERC's approach to ethanol research pivots on scale up. Here, an NCERC team member works in he facility's fermentation suite. Projects at NCERC typically begin with bench-scale work and bench-scale validation before advancing to pilot-scale/intermediate, fermentation and, eventually, 22,000-liter fermentations prior to commercialization efforts.

NCERC isn’t just about what its name implies. They do a lot more, from work on biorenewable polymers to municipal solid waste to ethanol processes.

The corn ethanol industry was 1.3 billion gallons when NCERC opened its doors. Today the industry is closer to 16 billion gallons. “We are still very true to our mission, which is to facilitate commercialization that can be used in the fuel ethanol space.”

Ethanol Research at Scale

There are many aspects of the center and its approach to ethanol research that are unique, but what stands out the most is its focus on scalability. According to Caupert, scalability is a driving force for his team of researchers and experts. The industry needs to operate at scale. There has to be a pathway or possibility of that, he says. “We take a deliberate approach to scale,” Caupert says.

When they start a project, they begin with bench-scale work and bench-scale fermentors. After they are satisfied with that step, they will move to piloting or intermediate fermentation that is 30L up to 1,500L.

“We spend a significant amount of time at intermediate-scale fermentation. Then, from there it's into the 22,000L bioreactors,” Caupert says.

At NCERC, when your project makes it to the 22k bioreactors, you are only a step away from the commercialization pathway. In some cases, NCERC has clients that come in with data already generated at their own facilities. They think they will be ready for the 22k bioreactors, Caupert explains. The team encourages them to relook at the early data. NCERC will, and often does. “If we can replicate what they have done, it is good to go.”

Most of the time, the work to validate the early data is actually credited back to the client, Caupert says. “We always find something in that early data.”

Roughly 90-percent of the time, the NCERC team discovers findings that are in favor of the client’s projects, usually associated with efficiency gains.

Reach Beyond R&D

You will be hard pressed to find a more passionate or well-spoken ethanol advocate than Caupert. He’s used that trait to help the center play a role in the ethanol industry’s place in the world of energy and politics.

“What I’ve learned in my time as executive director here is that we must as an industry continue to work—and work on the broadening and evolution of our base of friends and supporters,” he says.

NCERC is in a great place to educate others because of its prominence across the ethanol sector. Its depth of knowledge and
