When we think of tires, we usually think of traditional rubber plantations or petroleum-based synthetics. But what if your vehicle’s next set of tires grew in a field of yellow flowers?
German researchers at Continental and the Fraunhofer Institute developed Taraxagum—a natural, high-performance rubber derived directly from the Russian dandelion.
Why Dandelions Beat Traditional Rubber Trees
- Faster Harvest Cycle: Natural rubber trees take up to seven years before their very first harvest. Dandelions mature and can be harvested in a fraction of that time.
- Local Sowing & Reduced Supply-Chain Emissions: Rubber trees require tropical climates, leading to long global shipping routes. Dandelions thrive in temperate climates like Europe and North America, allowing crops to grow right near tire factories.
- Proven Track Record: Continental successfully built and tested passenger winter tires using dandelion rubber as far back as 2014, followed by heavy-duty commercial truck tires in 2016.
- While Taraxagum is still undergoing commercial scale-up and optimization before reaching store shelves worldwide, it represents a major leap forward in sustainable materials science.
