domestic plant called guayule. Guayule is a woody desert shrub cultivated in the southwestern United States as a source of natural rubber (latex), organic resins, and high-energy biofuel feedstock from crop residue.
Natural fibers which are used as fillers or reinforcement materials in polymer composites including palm sheath [7], palm leaf [8], guayule biomass [9], bagasse [10], sunflower stalk flour [11], banana [12], sugarcane, pineapple, ramie, and cotton [13] show many advantages such as renewability, biodegradability, C[O.sub.2] neutrality, nontoxicity, wide availability, low cost, low density, low energy consumption during fabrication, and high specific strength compared to synthetic fibers [14-16].
The Sustainable Bioeconomy for Arid Regions Center will focus on the desert shrub guayule and the food additive guar with additional research into the plants' potential uses as biofuels and other bioproducts.
