BOONE, N.C. — Four faculty members within Appalachian State University’s Department of Sustainable Technology and the Built Environment and the Department of Chemistry received $97,231 in funding from the North Carolina Department of Agriculture and Consumer Services (NCDA&CS) for their NEXUS research project, which is located at the Watauga County Landfill, in Boone.

These faculty are Dr. Jeremy Ferrell, assistant professor in Appalachian’s Department of Sustainable Technology and the Built Environment; Dr. Mike Hambourger, associate professor in Appalachian’s Department of Chemistry; Dr. Jim Houser, associate professor in Appalachian’s Department of Sustainable Technology and the Built Environment; and Dr. Ok-Youn Yu, associate professor and interim assistant chair in Appalachian’s Department of Sustainable Technology and the Built Environment.

“Ongoing research at Appalachian is demonstrating the use of biomass energy for greenhouse heating to help local agricultural producers extend growing seasons and increase yields through optimization of biomass and fossil fuel resources,” Ferrell said.

He and his team have demonstrated the production of syngas (synthetic natural gas) at Appalachian’s NEXUS greenhouse facility utilizing locally sourced wood waste, and, according to Ferrell, have used the combustion of the syngas to assist in greenhouse heating while producing the valuable soil amendment biochar to further support yields.

To assist local agricultural producers in developing the use of syngas for greenhouse heating, Ferrell said he and his team of researchers wish to demonstrate the viability of producing bioenergy crops on-site using marginal, non-arable, steeply sloped land. He said such production will serve to establish on-site production of bioenergy crops, while helping to stabilize fragile steeply sloped hillsides at the same time.

According to Ferrell, a recent acquisition of new acreage at Appalachian’s Nexus greenhouse research site will permit he and his team to grow locally appropriate bioenergy crops on-site for use in NEXUS’ existing gasification systems to demonstrate the viability of this biomass energy source for local producers.

Graduate students participating in the project are Barry Febos from Northampton, Massachusetts; Henry Mull ’17, a native of Hickory; and Devan Shumate ’17 of Willow Spring. Febos, Mull and Shumate are all graduate students in the appropriate technology concentration of Appalachian’s Master of Science in technology program.
