A tire maker is looking to get tires and biofuels to keep those wheels rolling from the biomass of a plant. This news release from Cooper Tire says the company completed tire builds using rubber derived from guayule plants and new guayule related materials and also hopes to get biofuels from those plant materials.
This development was reported by Cooper to its consortium partners—PanAridus, Arizona State University, Cornell University, and the Agricultural Research Service of the United States Department of Agriculture (USDA-ARS)—as the group met recently in Maricopa, Arizona for its third annual meeting and progress report on their $6.9 million Biomass Research and Development Initiative (BRDI) grant, “Securing the Future of Natural Rubber—An American Tire and Bioenergy Platform from Guayule.” The consortium received the BRDI grant in 2012 from the USDA and the U.S. Department of Energy (DOE) to conduct research aimed at developing enhanced manufacturing processes for the production of solid rubber from the guayule plant as a biomaterial for tire applications, as well as evaluating the plant’s residual biomass for fuel applications. The consortium aims to harness biopolymers extracted from guayule as a replacement for synthetic rubbers and Hevea natural rubber used in the production of tires. It is also focused on genomic and agronomic development of guayule and the sustainability impact these biomaterial and bioenergy industries have on the American Southwest, where guayule is grown.
So far, the testing shows the tires are at least equal to tires made of components derived from the more traditional Hevea rubber plant.
