On January 4, 2018, the U.S. Department of Agriculture’s National Institute of Food and Agriculture (NIFA) awarded the University of Tennessee a $2,994,429 grant to improve biorefinery technologies through the Integrated Biorefinery Optimization (IBO) program. The project aims to develop and commercialize solvent fractionated lignins to polymeric products for their potential market in building and construction sectors. The overarching goal of the research is to develop integrated pathways for the extraction of value-added polymeric products from lignin waste/under-valued stream from biorefineries. The IBO program is coordinated between NIFA and the U.S. Department of Energy’s (DOE) Bioenergy Technologies Office (BETO) and funds biorefinery technology development projects that aim to reduce costs and improve performance of integrated biorefineries to enhance U.S. energy security. Funding for the project comes from NIFA’s Agriculture and Food Research Initiative (AFRI), which addresses challenges in food and agricultural sciences through research, extension, and education.
