The daily message we receive from the media is that green is good. Green cars, green buildings, green plastic and now even green rubber should be the focus that we, as consumers, maintain. This is proving easier and easier to do; especially with products such as latex rubber made from a desert plant called guayule becoming more common.

Most rubber is derived from hevea, a product of the para rubber tree. Para rubber trees, native to Brazil, were transplanted to Southeast Asia where they have been carefully bred to increase hevea production. Today, most rubber comes from this region of the world, with the balance synthetically produced from petroleum. While it's true that most rubber is inherently organic, it's not necessarily "green"-at least not as green as guayule.

Beginning with proximity, the benefits of using rubber derived from environmentally-friendly plant guayule are simple to see. Whereas hevea must be grown overseas in tropical climates, the other natural source of latex rubber, guayule, can be grown in the southwestern United States and northern Mexico. The cost to the environment is lower than importing hevea-based rubber from overseas because of reduced fuel usage, since guayule is grown so close to home.

Second, guayule's location presents a green benefit. Guayule is a tremendously hearty plant, unlike hevea rubber produced from the common para rubber tree grown in tropical areas. Because it's naturally resistant, it does not require any chemical pesticides to keep its health. Para rubber trees are tremendously susceptible to leaf blight, so chemical pesticides are required to remain healthy. Chemical pesticides have been associated with various environmental and health risks, so guayule's natural pest resistance is significant.

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.

Finally, an excellent source of hypoallergenic natural rubber latex is guayule. A serious issue is hevea latex allergies. It's estimated that 10 percent of the U.S. population has a latex allergy. Currently, most hypoallergenic latex is synthetic rubber derived from a petroleum base. Obviously, a natural hypoallergenic rubber source is fundamentally superior to rubber synthesized from petroleum.

Because of import restrictions, leaf blight decimation, and common latex allergies among health care providers guayule gained popularity throughout the 20th century. Although more rubber can be produced from a single para rubber tree than a guayule plant, the overall greenness, locale, energy-producing potential and hypoallergenic qualities of the guayule plant is unbeatable.

The question now 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 producing the crop and working to manufacture latex products from it. To invest in the success of the environment and the affordability of guayule produced rubber products, a sure way is to find ways to support these entities.
