Who We Are
The Sustainable Bioeconomy for Arid Regions (SBAR) Center of Excellence 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.
What We Do
SBAR works to optimize and integrate the production of guayule and guar to enable the Southwest United States to significantly impact the biofuels and other high-value product markets. Scientists are collaborating on research, development, and deployment (RDD) activities to:
- Improve feedstocks and produce them in a sustainable manner;
- Identify new value-added co-products that increase marketability;
- Understand how conversion to fuel is affected by variable feedstock quality; and
- Augment transportation, techno-economic, and sustainability models to provide a clear path to commercialization.
These RDD activities are complemented by bagasse conversion and upgrading to fuel via pyrolysis, hydrothermal liquefaction, and acid hydrolysis.
To provide stakeholders, interested in expanding crop options that support the rubber and biofuel industries, with regional solutions that are economically viable, socially acceptable, and meet the water conservation needs of the arid Southwest (AZ, CA, NM, and TX).
How We Inform
The Extension and Outreach Team serves as a conduit between researchers and community stakeholders, helping to transfer the science and technology of guayule and guar production to communities in the Southwest. They provide resources like research results, bulletins, videos, webinars, field tours, youth camps, and workshops on biofuels and other energy issues.
To engage citizens, meet future workforce needs, and enhance science literacy in agriculture and biofuels, the Education Team creates and disseminates K-12 biofuel curriculum. Program implementation includes mentoring Graduate Student Fellows and teachers in Arizona and New Mexico. Summer and school-year internships are provided to high school students and undergraduate students on a variety of agriculture and biofuel topics.
Why Biofuels in the Southwest Matter
Water Conservation: Using desert-adapted plants for generating rubber and fuel reduces water required for rubber and fuel production.
Economy: Job creation and rural development is enhanced throughout the region.
Energy Security: Locally produced natural rubber and fuel reduces the dependence on foreign natural rubber and fuel.
Environmental Benefits: Guar can be grown in crop-rotation and fixes nitrogen in the soil, reducing the need for high inputs like herbicide and fertilizers for future crops. Guayule uses less water than traditional crops over 2 years.
Infrastructure Compatible: The natural rubber produced is chemically equivalent to Hevea-based rubber and chemicals.
The Sustainable Bioeconomy for Arid Regions (SBAR) Center is led by the University of Arizona and funded through a research and education/extension grant provided by the USDA National Institute of Food and Agriculture (NIFA) – Agriculture and Food Research Initiative. Grant # 2017-68005-26867.
