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 do you harvest natural rubber?

Rubber is harvested from rubber trees, which are a family of trees that belong to the family Euphorbiace; Hevea brasilienisis or Sharinga trees are the most common. Natural rubber is extracted by method called tapping, by making incisions into the bark and collecting the fluid into vessels attached to the rubber trees.

Can you make rubber from dandelions?

Dandelions contain a small amount of the latex needed to make rubber. The researchers extract this substance from the dandelions and are able to make rubber from it.

How is rubber cultivated?

Rubber cultivation in plantation is a systematic agriculture in which first seeds have been raised in a nursery. When the rubber seedlings are about 5 cm in diameter buds from high yielding clones are grafted on to the seedlings. Cover crops are usually planted between the seedling trees to prevent soil erosion.

How is rubber farmed?

Currently, rubber is harvested mainly in the form of the latex from the rubber tree (Hevea brasiliensis) or others. The latex is a sticky, milky and white colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called “tapping”.

How is dandelion rubber made?

Once the dandelions are harvested “hot-water extraction” is used to separate out the rubber. “The roots are chopped up mechanically and water is added,” van der Meer explained. “It has to be heated up, but no large volumes of chemicals are needed.

Where is rubber cultivated?

Nowadays, around 90\% of natural rubber is produced in Asia, with Thailand and Indonesia being the most important rubber suppliers (supplying more than 60\% of the world’s natural rubber).
