Green is good. That is the daily message we receive from the media. The focus that we, as consumers, maintain should be on green cars, green buildings, green plastic and now even green rubber. With products made from a desert plant called guayule, (such as latex gloves especially) this is proving easier and easier to do.
Hevea, a product of the para rubber tree, is what most rubber is derived from. Para rubber trees are native to Brazil. They were transplanted to Southeast Asia and have been carefully bred to produce increased hevea. Most rubber comes from this region of the world today, with the balance synthetically produced from petroleum. While it's true that most rubber is organic inherently, it's not "green" necessarily-at least not as green as guayule.
The benefits of using environmentally-friendly rubber derived from the guayule plant are simple to see, beginning with proximity. Whereas guayule can be grown in northern Mexico and the southwestern United States, hevea, the other natural source of latex rubber, must be grown in tropical climates. Because of reduced fuel usage, since guayule is grown so close to home, the cost to the environment is lower than importing hevea-based rubber from overseas.
A second green benefit presented is guayule's location. Unlike the common hevea rubber produced from para rubber trees grown in tropical areas, guayule is a tremendously hearty plant. To keep its health it does not require any chemical pesticides because it's naturally resistant. To remain healthy para rubber trees require chemical pesticides because they are tremendously susceptible to leaf blight. Guayule's natural pest resistance is significant since chemical pesticides have been associated with various health and environmental risks.
Guayule's third green attribute is that it can be used as an ethanol feedstock. Guayule is not a food source, unlike corn, which is commonly used to make ethanol, and therefore doesn't impact the world's food source in price or availability. The demand for corn produced ethanol, in some situations, has impacted the food supply in the market. But that isn't an issue since guayule is not a food source.
Guayule is an excellent source of hypoallergenic natural rubber latex, finally. It's estimated that 10 percent of the U.S. population has a latex allergy; hevea latex allergies are a serious issue. Most hypoallergenic latex is derived from petroleum-based synthetic rubber, currently. A natural source of hypoallergenic rubber is fundamentally superior to rubber synthesized from petroleum, obviously.
Guayule gained popularity throughout the 20th century because of import restrictions, leaf blight decimation, and common latex allergies among health care providers. Although a single para rubber tree can produce more rubber than a guayule plant, the locale, energy-producing potential, hypoallergenic qualities, and overall greenness of the guayule plant is unbeatable.
Now the question is how do green-conscious consumers support this product? Local farmers in the southwestern U.S. and northern Mexico, along with the Yulex Corporation, are working to produce the crop and manufacture latex products from it. Finding ways to support these entities is a sure way to invest in the success of the environment and the affordability of guayule produced rubber products.
