Sustainable Bioeconomy for Arid Regions (SBAR)

The Sustainable Bioeconomy for Arid Regions (SBAR) is a five-year project funded by the U.S. Department of Agriculture’s National Institute of Food and Agriculture led by the University of Arizona, with partner institutions: New Mexico State University, Colorado School of Mines, and Colorado State University. The goals of the grant are to research and develop the production and conversion of guar and guayule into high value commodities to create a sustainable bioeconomy in the southwest United States. SBAR is divided into two portions, research, and education, extension, and outreach.

SBAR GK-12 Education and Outreach  

The SBAR GK-12 works with teachers and graduate fellows, in New Mexico and Arizona. Researchers in the GK-12 team work on finding SBAR education resources for educators and graduate fellows to use in the classroom/online settings. Researchers are able to design and modify resources so they may better service teachers and students.  

Students: Darien Pruitt, Paramveer Singh, Mostafa Dehghanizadeh, Jacob Usrey, Brian Treftz, Rodrigo Rosalez, Meshack Audu, Esai Lopez, Sarah Fox  

SBAR Research: Utilization of Guayule Bagasse and Resin  

After the extraction of natural rubber from the guayule feedstock, two residue streams as created: resin and bagasse. Resin is a complex, sticky mixture of fatty acids, argentatins, guayulins, other terpenoids, low-molecular-weight rubber, and many others. Resin has potential applications in asphalt, adhesives, polymers, chemicals, and pest repellents. Bagasse is the woody, fibrous biomass not converted to rubber or resin. Our group is working on characterizing guayule bagasse samples and finding the most efferent method of converting the bagasse into renewable energy products, ideally liquid transportation fuels.
