IMPACT and CONTRIBUTION
APWMC program management: Established in 1996, the APWMC is a research partnership of NCSU, the private sector, commodity organizations, other universities, environmental organizations and government agencies. Primary program focus areas include the development of innovative animal waste treatment technologies and environmental technology performance verification. Currently, the APWMC is coordinating the NC Attorney General Agreements with Smithfield Foods & Premium Standard Farms for the development, identification, and implementation of "Environmentally Superior Technologies".
RESEARCH INTERESTS
Research interest: Biotechnology applications for value-added processing of animal by-products. Anaerobic fermentation of animal manure for energy production, odor control, and pathogen management. Stable isotope geochemistry for determining the fate of land applied animal manure.
