The Sustainable Bioeconomy for Arid Regions (SBAR) Center of Excellence, up to $15 million over a five year period funded by the U.S. Department of Agriculture’s National Institute of Food and Agriculture,  was established in September 2017, with the intended purpose of developing a systems approach for feedstock development, production, and delivery in the Southwest United States. It is further enhanced by the development and implementation of education, extension and outreach to teachers, 4-H youth groups, and farmers across the region.

Model and Algorithm Development for Smart Biomass Supply Chain for Guar and Guayule

Dr. Fan’s group applies optimization techniques for design and operations of biomass supply chain and feedstock logistics in economically efficient and environmentally sustainable ways, to co-produce biofuels and bioproducts from guayule and guar. The whole study consists of development of three decision support modules.
