In the heart of Iowa, a revolution is quietly unfolding, turning agricultural waste into the fuels, chemicals, and products of tomorrow.
Explore the InnovationImagine a future where the leftover stalks and leaves from a corn harvest power our cars, heat our homes, and form the building blocks for sustainable plastics. This is not a distant dream but the daily reality at Iowa State University's BioCentury Research Farm (BCRF).
As the first facility in the nation to fully integrate biomass production and processing under one roof, this unique farm is a living laboratory where scientists, engineers, and students are building a more sustainable future 1 .

Since its opening in 2009, the BCRF has become an internationally recognized home for cutting-edge bioeconomy science. It has supported over $85 million in grant funding and more than 50 research projects annually, all while training the next generation of innovators who go on to careers at leading companies like John Deere and SpaceX 1 . Here, the entire supply chain—from a single seed to a finished bioproduct—is reimagined and optimized.
The genius of the BioCentury Research Farm lies in its integrated approach. Unlike a traditional lab focused on a single discipline, the BCRF brings together diverse scientific expertise to tackle the entire lifecycle of biomass.
The work begins with the soil. On over 1,100 acres in Boone County, Iowa, researchers study and demonstrate the most effective ways to grow and manage biomass crops 7 .
After harvest, biomass enters the state-of-the-art Biomass Storage and Pretreatment Building capable of handling over two tons of material per day 3 5 .
| Research Area | Primary Goal | Example Projects & Impact |
|---|---|---|
| Digital Agriculture 3 | Use technology to support agricultural decisions and risk mitigation. | UAV (drone) research for crop health assessment; yield monitor technology recognized with a Silver Medal at Agritechnica. |
| Biomass Supply Chain Management 3 | Develop sustainable and efficient methods for biomass production. | Achieved a 40% cost reduction in corn stover production; developed best storage practices for year-round biorefinery operation. |
| Thermochemical Conversion 3 | Convert biomass into bio-oil and syngas using heat. | Home to pilot-scale fast pyrolysis and gasification systems that create intermediates for fuels and chemicals. |
| Biochemical Conversion 9 | Use fermentation and other biological processes to create products. | Large pilot-scale dry-grind ethanol plant; production of bioplastics, bio-pesticides, and food supplements. |
One of the most groundbreaking technologies developed at the BCRF is the Fast Pyrolysis Process Development Unit (PPDU). Pyrolysis is a thermochemical process that rapidly heats biomass in the absence of oxygen, causing it to break down into a vapor that is then condensed into a dark, energy-rich liquid called bio-oil.
The shift to autothermal operation did more than just save energy; it tripled the capacity of biomass throughput using the same reactor footprint, dramatically improving the process intensity 3 .
Biomass like corn stover or wood is ground into fine particles to ensure consistent and rapid heating 3 .
The ground biomass is fed into a pilot-scale reactor that can process 22 kilograms of biomass per hour continuously. Inside, a stream of air suspends the biomass particles, behaving like a boiling fluid for efficient heat transfer 3 .
The clever innovation is using 100% air fluidization. A portion of the biomass feedstock is intentionally combusted within the reactor, generating enough heat to drive the pyrolysis reaction for the rest of the material. This creates a self-sustaining system that requires no external fuel 3 .
The resulting vapors are not simply condensed into a single bio-oil. They are passed through a patented multi-stage collection system that separates them into distinct, higher-value fractions, such as fermentable sugars and phenolic oils 3 .
Sugar yield from corn stover increased by 15 times through pretreatment methods 3
Biomass throughput tripled using the same reactor footprint 3
| Feedstock Type | Processing Capacity | Notable Outputs Produced |
|---|---|---|
| Corn Stover 3 | 60 tons processed for the National Advanced Biofuels Consortium | Provided 100-micron stover to the U.S. Department of Energy |
| Woody Biomass (e.g., Oak, Pine, Poplar) 3 | Handled in large and small quantities | Successfully torrefied (roasted) feedstocks to create a higher-energy solid product |
| Other Herbaceous Crops (e.g., Switchgrass, Sorghum) 3 | Over 100 tons of modified material provided | Served material to every major university, company, and national lab working on biomass-to-fuels |
The research at BioCentury is made possible by a suite of advanced tools and materials. The following table details some of the key "research reagent solutions" essential for converting raw biomass into valuable bioproducts.
| Tool/Reagent | Primary Function in Research | Specific Application Example |
|---|---|---|
| Specialized Microbes | Ferment sugars into valuable products. | Used in the BCRF's pilot-scale fermentation vessels to produce bioplastics, bio-pesticides, and recombinant proteins 9 . |
| Fluidizing Air | Creates a "boiling" bed of solid particles for efficient heat transfer. | Enables the autothermal pyrolysis process, where air is used to both fluidize and partially combust the biomass, making the system self-heating 3 . |
| Proprietary Solvents | Dissolve and break down the tough structure of biomass. | In the solvent liquefaction system, a proprietary solvent mixed with biomass helps produce a bio-oil with very low oxygen content, suitable for drop-in transportation fuels 3 . |
| Biochar | A solid, carbon-rich co-product of pyrolysis. | Acts as a soil amendment to improve health and sequester carbon; can also be used as a high-porosity filter material 3 . |
| Limestone Sorbent | Removes contaminants from gas streams. | Injected into the gasifier to remove sulfur compounds, ensuring the produced syngas is clean enough for sensitive downstream processes like fermentation 3 . |
The work at the BCRF extends far beyond the lab, generating tangible economic and educational benefits for Iowa and the broader Midwest.
The BCRF is a training ground for future scientists and engineers. More than 260 undergraduate students have been employed at the facility, gaining hands-on experience that launches them into careers at leading agricultural and engineering firms 1 .

The BioCentury Research Farm stands as a powerful testament to the potential of a circular, biobased economy. By treating agricultural residues not as waste but as a valuable resource, the researchers in Boone are reducing our reliance on fossil fuels, creating new economic opportunities, and promoting environmental stewardship.
The vision is clear: to make Iowa the preferred location for biorefineries and Iowa State University "the place" for developing cutting-edge bioeconomy technologies 1 . As research continues—from integrating strip-till management with stover harvesting to developing pilot-scale "modular refineries"—the BioCentury Research Farm will undoubtedly remain at the forefront, turning the promise of a renewable future into reality, one biomass pellet at a time.
