Wired - The Superplant That May Finally Topple the Rubber Monopoly 5-15min

Mathur explains how he and his company, Yulex, hope to break the Asian rubber monopoly using gene sequencing and an unassuming desert plant. ... what he’s trying to do here in the desert, with a plant called guayule. ... Mathur tears a stem from one shrub and peels back the bark, pointing to a thin layer of, well, softness. This is called parenchyma. You can use it to make rubber, and that means you can make wetsuits, condoms, gloves, catheters, angioplasty balloons, and so many other medical devices. But most importantly, you can make tires. Car tires. Truck tires. Aircraft tires. In fact, this sort of natural rubber is essential to making tires. Yes, we now have synthetic rubber, but that isn’t as strong as the natural stuff. Our automobile tires contain about 50 percent natural rubber, and you simply can’t make a truck or aircraft tire without it. ... Today, almost all natural rubber comes from hevea rubber trees grown in Southeast Asia, and that hangs a nightmare scenario over US tire makers and the wider US economy. In the event of war or natural disaster, our supply could vanish, and rather quickly. But guayule can provide an alternative. Since the early 20th century, American researchers, entrepreneurs, and statesmen have eyed the plant as a way of freeing the U.S. economy from this deep dependence on Asia. Rubber trees don’t do well in the US, but guayule does. It’s indigenous to Mexico and the American southwest.
