Continental Taraxagum: When the Dandelion Becomes the Raw Material of Tomorrow's Tire
Last modified on June 8th, 2026 in News
Over one billion tires are manufactured every year around the world, and every single one requires the same essential ingredient: natural rubber. But what if the weed you pull from your lawn every spring became a key raw material in the tire of the future? That's exactly what Continental has been exploring since 2011 with its Taraxagum project.
Natural Rubber: An Essential Ingredient Under Threat
Natural rubber accounts for approximately 41% of a tire's composition. Until now, it has been almost exclusively extracted from Hevea brasiliensis, a tree native to Brazil, now cultivated primarily in Southeast Asia. The extraction process is similar to tapping maple sap: a cut is made in the bark to collect the latex, a thick, milky fluid. A Hevea tree takes 7 years to mature before producing latex and can only be tapped for around 30 years.
The problem? A single Hevea tree yields only about a cup of latex every three hours, a limited output for a rapidly growing global demand. Worse, the species is now threatened by a parasitic fungus that could jeopardize the global natural rubber supply in the coming decades. The tire industry must anticipate this risk and find reliable alternatives.
The Russian Dandelion: A Surprising but Promising Alternative
The solution came from an unexpected source: the Russian dandelion (Taraxacum kok-saghyz). Researchers discovered that the roots and stems of this particular species also contain a latex with properties very similar to those of Hevea. Even better: its mechanical and chemical properties proved equivalent to those of traditional natural rubber, making it a technically viable substitute for tire manufacturing.
The geographical advantage is significant: unlike the Hevea, which only grows within a narrow tropical belt, the Russian dandelion can be cultivated across much wider latitudes, including in Europe. This means significantly shorter supply chains, reduced transport emissions, and greater independence from volatile tropical commodity markets.
In Germany, scientists at the Fraunhofer Institute for Molecular Biology and Applied Ecology (IME) have even managed to genetically optimize the dandelion to increase its latex content and improve industrial extraction efficiency.
The Taraxagum Project: Continental Leading the Way
As early as 2011, Continental became the first tire manufacturer in the world to invest significantly in dandelion rubber. The project, named Taraxagum, is conducted in collaboration with leading scientific partners including the Fraunhofer IME Institute and the University of Münster.
The project milestones speak for themselves:
- 2014: successful road tests on a prototype winter tire (WinterContact TS 850 P model) incorporating dandelion rubber in the tread.
- 2016: unveiling of the first truck tire made from dandelion rubber at the Frankfurt Motor Show. Opening of the Taraxagum Lab Anklam research facility in Germany, backed by a planned investment of €35 million.
- 2018: launch of the Urban Taraxagum, the world's first mass-produced bicycle tire made entirely from dandelion rubber. The tire is commercially available.
- 2022: expansion of the research partner network to accelerate dandelion breeding for industrial-scale rubber production.
Continental's long-term goal is clear: to introduce dandelion rubber into the serial production of passenger car and truck tires, as a partial or complete replacement for Hevea rubber.
An Innovation That Goes Beyond the Tire
The Taraxagum project isn't limited to tires. Continental has also successfully tested dandelion rubber in the manufacturing of engine anti-vibration mounts, components that require very precise elastic properties. This result demonstrates that the material is viable for a much broader range of industrial applications.
Beyond the technical achievements, Taraxagum is part of a broader sustainability strategy: reducing COâ‚‚ emissions from transportation, making better use of underutilized European agricultural land, and decreasing dependence on tropical raw materials increasingly threatened by climate change.
The dandelion, that stubborn little flower we spend so much energy removing from our gardens, may well become one of the symbols of sustainable mobility for the future.
