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.

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.

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).

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.

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.

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.

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.

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.
