American rubber production begins with growing rubber plants, such as guayule (pronounced "why-you-lee"), which "grows wild in parts of Texas and Mexico, but it's also easy to cultivate and grow on farms throughout the region. Drought-tolerant and disinclined to disease, there's not much that bothers it," Morgan explains. When Guayuule stems are ground up and put "through a process of distillation and filtration, the result is a high-quality natural latex" for producing "everything from surgical gloves to car parts. . . . Many believe this shrub is the best candidate for developing a domestic rubber market."

The next hurdle for American rubber production is finding a manufacturer. Katrina Cornish, professor of horticulture and biological engineering at Ohio State University, told Morgan, "It's all there, there's just no processing infrastructure. We've got farmers who are willing to grow these crops and lots of companies wanting to buy the latex. We need a full-scale processing plant, and we're looking at somewhere around a $70 million price tag." Morgan reports, "Once it's refined, Cornish added, rubber made from guayule or any other plant could be used — it could upend our entire rubber supply chain."
