The Potential of Guayule

Guayule, pronounced why-YOU-lee, provides an alternative and sustainable commercial source of rubber for breakthrough biomaterials. Since 1998 American BioRubber (formally the Yulex Corporation) has led the industry in developing guayule crops to create sustainable rubber products.

About the Guayule Plant

  • Guayule is a perennial, non-food crop

  • 1-2 years to first harvest, then annual harvests (variety dependent)

  • Grows successfully in marginal land

  • Low water usage compared to cotton/alfalfa (~6 acre feet/year)

  • 18+ tons of residual dry biomass/acre

  • Tremendous upside through agroscience development activities

  • Aligns with existing agronomic practices (automated)

  • High output = 1 ton

  • Rubber/acre/year, already equal to SE Asian rubber plantations (per acre basis)

Guayule (Parthenium argentatum), a woody, evergreen shrub that originated in the deserts of the U.S. Southwest and Mexico. Is the only species other than the Brazilian rubber tree (Hevea brasiliensis) that is used commercially for the production of rubber.

The largest portion of rubber is contained in the stem, specifically in the cells of the bark. The rubber produced is very similar to the rubber tree but with the added advantage is that is allergen free.

Amercian Biorubber and Guayule

American Biorubber has pioneered many “firsts” in guayule crop science, bioprocessing and material science

Notable Firsts for American Biorubber

First to refine guayule seed oil for omega-3’s2020-09-17T17:36:07+00:00

American BioRubber was the first company to developed multiple processing methods for the extraction and refinement of guayule seed oil, a unique oil high in Linolenic Acid which is an essential fatty acid belonging to the omega-3 fatty acids group.

First eco-friendly replacement for neoprene2020-09-17T17:36:14+00:00

The company developed and commercialized the first all-natural replacement for neoprene foam used in wetsuits when we partnered with Patagonia.

First FDA approved medical grade guayule product2020-09-17T17:48:33+00:00

American BioRubber was the first company in history to develop, test and validate medical examination and surgical gloves with the FDA.

Frequently Asked Questions

Is guayule derived rubber non-allergenic?2020-09-17T17:35:21+00:00

Guayule produces a high molecular weight cis, 1-4, polyisoprene rubber with exceptional characteristics and high-quality physical properties and unlike crude hevea, guayule is free from allergy causing proteins making it a much safer option for sensitive populations.

Can you transplant guayule?2020-09-17T17:30:48+00:00

Transplanting guayule as a row crop is straightforward, using slightly modified equipment, however ensuring the transplant is placed at the correct depth with the right soil moisture level is critical as is the initial field nutrient load. Get it wrong for your region and stunted crop growth is likely, even total crop loss.

Is the guayule you produce non-GMO?2020-09-17T17:46:40+00:00

American BioRubber has made tremendous strides in breeding guayule with high quality commercial traits. Utilizing molecular breeding technologies that don’t require genetic manipulation or modifications (GMOs).

Can guayule be used to produce cellulosic ethanol?2020-09-17T17:29:28+00:00

Guayule can be used very effectively to produce cellulosic ethanol. During a national study performed by the departments of Energy and the USDA guayule was the preferred feedstock over corn, forest waste, switchgrass and mother crops and was able to produce billions of gallons of fuel grade alcohol in half the land needed for other crops. A key benefit was that guayule grow very well on arid lands unsuitable for other crops.

What do you do with the fiber left over from processing guayule?2020-09-17T17:28:01+00:00

Bioprocessing guayule for rubber and resin which leaves behind considerable fiber that is an enormous benefit to producing companies and governments as this fiber allows for the ongoing revenue streams in the production of particleboard, engineered wood composites, fuel pellets for green energy production, or clean tech chemical production of feedstock basics such as succinic acid, biogas, ethanol, as well as biochar.

What guayule production facilities has American Biorubber constructed?2020-09-17T17:26:52+00:00

American BioRubber has designed, engineered and constructed processing facilities ranging in size from bench scale to lab and larger than lab, pilot and demonstration scale to massive production sites in ranges from 25,000 to 150,000 metric ton per year using either our water based process or our solvent based process.

How is rubber and resin extracted from guayule?2020-09-17T17:17:52+00:00

There are multiple extraction methods for efficiently removing rubber and resin from the guayule plant. American BioRubber has developed and patented a green tech water based process for extraction of liquid rubber latex as well as a solvent based removal process which easily removes liquid and solid rubber as well as resins which are separated as a two-step pass or singularly in subsequent steps. American BioRubber has also pioneered the use of supercritical extraction using carbon dioxide, water and a small percentage of hydrocarbon depending on the blend required in the extraction vessel.

Where does the guayule plant store its rubber?2020-09-17T17:46:54+00:00

Guayule stores its rubber as a liquid and solid in the bark or parenchyma of the stems in small cells. These cell and surrounding areas also store a small portion of resin which is removed and separated during processing.
