$10 Million Grant Funds Research to Turn Biomass and Manure into Fuel

A new federal grant will fund a research team led by Iowa State University, Penn State and Roeslein Alternative Energy to develop new methods of turning biomass and manure into fuel. The five-year, $10 million grant from the USDA’s National Institute for Food and Agriculture will fund the Consortium for Cultivating Human and Natural reGenerative Enterprise (C-CHANGE) as it works to create “new value chains on U.S. farms, with emphasis on the generation of natural gas, improved rural economic outcomes and protection of the environment,” according to a release from Iowa State.

Lisa Schulte Moore, a professor of natural resource ecology and management and associate director of the Bioeconomy Institute at Iowa State will be the project director. She says the consortium will create methods for farmers to make more efficient use of resources while maintaining current value chains, leading to an ag economy that’s both more profitable and environmentally sounds, the release says.

“We recognize the benefits of current production systems but also that there’s a lot of inefficiency in how we use land, sunlight, nutrients and water,” Schulte Moore said in the release. “We also realize that farmers and rural communities are struggling. We know we can address inefficiencies by adding perennials and recoupling crop, livestock and energy systems. Research is needed to ensure these combinations are also profitable.”

Researchers at C-Change are working to develop new ways for farmers to produce renewable natural gas that could be used as an energy source both on and off farms. The project centers on using anaerobic digestion to break down biomatter and produce biogas, which is mostly methane, the main component of natural gas. The release states that with new separation technology, biogas can be upgraded to renewable natural gas and distributed through the gas pipeline network.

Part of what the researchers are experimenting with is how to optimize the digesters, testing variables such as feedstock mixture, pretreatment, digester temperature and water content to make the process as practical as possible.

“For more than 50 years, anaerobic digestion has been promoted as a way to both improve environmental management of livestock manures and to produce renewable energy,” said Tom Richard, director of Penn State’s Institutes of Energy and the Environment in the release. “But adoption of anaerobic digestion has been limited by high capital costs and management complexity, which has slowed the advance of this industry and the underlying technology. We will be working with farmers and other industrial partners to update anaerobic digestion for the 21st century, applying the principles of process intensification, automation and economies of scale to reduce costs, simplify operations and expand digester feedstocks beyond manure to incorporate perennial grasses and winter crops into their operations as a source of biomass for the digesters.”

Roeslein Alternative Energy has already been doing work in the areas of study funded by the grant. Since 2012, Roeslein has been working with Smithfield Foods to adjust practices on their hog farms that have resulted in greater efficiencies, improved environmental outcomes and a profitable new renewable natural gas enterprise, the release asserts. Research will help determine additional markets for the products of anaerobic digestion. For example, the digestate – or material remaining after anaerobic digestion – could be reapplied to fields to enrich soils after the biogas has been removed. The decomposed digestate should provide a more stable source of nutrients than directly applying manure as a fertilizer, resulting in lower greenhouse gas emissions and less nutrients running into waterways.

Rudi Roeslein, founder or Roeslein Alternative Energy, said energy production from biogas could spark significant job creation in the alternative energy and agriculture sectors while also providing new habitat for threatened wildlife, including pollinators.

“With this grant, we hope to demonstrate that land unprofitable for annual crops could be used for renewable energy production from native grasses and forbs through the anaerobic digestion process, Roeslein said in the release. “Ecological services from this perennial biomass crop would prevent flooding, reduce nutrients running into our streams and rivers that could save hundreds of billions of taxpayer money on water treatment facilities while improving the health of our future generations.”

In addition to Iowa State, Penn State, and Roeslein Alternative Energy, other institutions involved with the new C-CHANGE grant include FDCE of New Albany, Ohio; the USDA Agricultural Research Service National Laboratory for Agriculture and the Environment in Ames, and 33 partner organizations.
