Guayule is an evergreen shrub that originated in the arid zone from the southwestern part of the USA to northern Mexico and therefore can be grown in environments totally different from those suited for para rubber trees (the current primary source of natural rubber (*1)).

Where does the rubber come from?

Formed in a living organism, natural rubber consists of solids suspended in a milky fluid, called latex, that circulates in the inner portions of the bark of many tropical and subtropical trees and shrubs, but predominantly Hevea brasiliensis, a tall softwood tree originating in Brazil.

What is guayule used for?

Guayule (Parthenium argentatum) is a relatively new commercial crop and the only species other than the Brazilian rubber tree (Hevea brasiliensis) that has been used for latex pro- duction on a commercial scale. Guayule is the only source of natural rubber latex free of tropical proteins.

Where are rubber trees native?

Hevea brasiliensis is a species of rubberwood that is native to rainforests in the Amazon region of South America, including Brazil, Venezuela, Ecuador, Colombia, Peru, and Bolivia.

How is guayule rubber made?

Guayule requires a series of process to produce natural rubber consisting of grinding whole plant, solvent extraction and impurity removal, which is more complex than the natural rubber production process concerning para rubber trees that requires coagulation and drying of latex only.

How is guayule rubber harvested?

Latex flows freely within channels in rubber trees. Workers simply tap the plant to let the latex flow into buckets. In guayule, the rubber is trapped within the plant's cells and must be extracted after the plant reaches maturity, which takes two or three years.

Are trees used to make tires?

The para rubber tree is originated in Brazil. Its latex extracted from the tree's trunk is a major source of natural rubber, which is the primary material in tires. Natural rubber is produced by coagulating/drying latex extracted from para rubber trees for five to 25 years after their plantation.

Why are all tires black?

The rubber that tires are sourced from is a milky white color, but carbon black is added to the rubber as a stabilizing chemical compound and makes the tire black. ...
