Plantwatch: Russian Dandelion Offers Solution to Global Rubber Shortage

AI Summary

Scientists are reviving the Russian dandelion as a sustainable source of natural rubber amid a global shortage. A Norwich biotech partnership aims to produce about 3,000 tonnes annually, while German firms already use dandelion‑derived rubber for bicycle tyres.

The Lead: Dandelions Re‑Enter the Global Rubber Supply Chain

Amid a widening natural‑rubber deficit, researchers are turning back to the Russian dandelion, Taraxacum koksaghyz, a plant once used in World War II to supplement rubber supplies.

Biotech Partnership in Norwich Develops High‑Yield Russian Dandelion

A collaboration in Norwich is engineering a fast‑growing, high‑yield variety of the dandelion. The plants are cultivated in glasshouses using a soil‑free mist system, targeting large, rapid‑growth roots that produce latex suitable for rubber extraction.

Projected Output of 3,000 Tonnes Highlights Scale

Annual production goal: 3,000 tonnes of natural rubber.
Compared with traditional Hevea brasiliensis plantations, the dandelion requires far less water and no pesticides.
German manufacturers have already produced bicycle tyres from dandelion‑derived rubber.

Environmental and Supply Benefits of a Soil‑Free Dandelion Crop

The new crop offers several advantages: it thrives in temperate climates, reduces deforestation pressure on tropical rubber forests, and is resilient to the fungal diseases and extreme weather linked to the climate crisis.

Future Outlook: Expansion of Dandelion Rubber Across Europe

If the Norwich project meets its target, the model could be replicated in other temperate regions, providing a sustainable, locally sourced rubber alternative and easing the global supply bottleneck.
