Towards dandelion days

By Sharad Matade

As part of its sustainability efforts, Continental aims at using at least ten percent of natural rubber derived from Russian dandelion roots in its tyre and industrial rubber goods production in future.

“We have undertaken a huge research task to meet ten percent of our requirement of natural rubber from dandelion roots. It is a long-term process,” Dr Carla Recker, Head of Expertfield Materials Chemistry & Taraxagum, told Tyre Trends in an interview. “It will take decades to complement natural rubber from Hevea brasiliensis with natural rubber from dandelion plants at an industrialised level. However, the company does not intend to replace NR from Hevea brasiliensis trees.”

According to Dr Carsten Venz, Site Manager at Taraxagum Lab Anklam, “Dandelion will be an additional source of natural rubber, not a replacement to rubber trees, in the coming years.”

Continental started working on the dandelion rubber project in 2011, and the company has already used rubber from dandelion roots in its passenger car tyres, truck tyres and industrial rubber goods. The latest on production-side is its industrialisation on bicycle tyres

Continental has been consequent on the cultivation and processing of Russian dandelion as an alternative source of raw material to the rubber tree in the tropics. Last year, the company officially opened its research and test laboratory named Taraxagum Lab Anklam in Anklam, Germany, a base for its future research into the cultivation and processing of Russian dandelion, within a year after the ground-breaking ceremony held in November 2017.

“The Taraxagum Lab Anklam is the latest key milestone of our project,” said Dr Recker.

The Taraxagum project is crucial for the company. “The natural rubber from dandelion is important to develop a new alternative and sustainable supply of the raw material” Dr Venz said.

On bicycle tyres

Though the lab was opened last year, Continental started working on the dandelion rubber project in 2011, and the company has already used rubber from dandelion roots in its passenger car tyres, truck tyres and industrial rubber goods. “The latest development on production-side is that we have industrialised bicycle tyres with rubber derived from dandelions. So, you can now buy bicycle tyres of Continental made of dandelion rubber in the market,” Dr Recker said. Continental showcased its first bicycle tyre with dandelion rubber at the Tour de France this year.

Currently, the Taraxagum lab is working on dandelion research, and over the next five to ten years, it will focus on the industrialisation of dandelion rubber and increase the share for the dandelion rubber in its products.

“Continental sees the Russian dandelion as one element of our commitment for sustainable natural rubber as detailed in our Sustainable Natural Rubber Sourcing Policy published in October 2018. At least for us, the Russian dandelion is the most promising alternative source for natural rubber. There might be different sources (to get natural rubber), but that does not fit for us. The Russian dandelion can be grown in different climate zones unlike natural rubber from heave brasiliensis trees which need tropical climates to grow. Rubber trees and the Russian dandelion have the same characteristics, the same chemical structure and the same properties. It is just two plants producing the same material,” says Dr Recker. The advantage of dandelion rubber over rubber from trees is that the former has a generation succession of just three months as compared to seven years for the latter.

Since the dandelion plants can be cultivated in Northern and Western Europe, which makes transportation routes to the European production sites much shorter and contributes to the sustainable use of existing resources, thinks Continental.

However, the major challenge will be the 100 percent replacement of rubber made from trees with dandelion rubber. Dr Recker thinks, yes, technically, dandelion can replace tree rubber by 100 percent, but the more significant challenge will be the industrialisation of dandelion rubber to the level of rubber trees. “We are at a research stage. The amount of dandelion available globally is not enough to replace natural rubber commercially. To create that biological system to industrialise the natural rubber from the dandelion will take some time and we will have to be more patient,” says Dr Recker.

Research is a time and capital consuming task. Synthetic rubber is also coming into tyre production in a more significant way, but the crude oil derived commodity has historically been volatile, and even oil-producing nations are diversifying their businesses citing falling productions and growing focus on cleaner options.

Dandelion rubber is not new to the tyre industry; however, the industry does not seem much keen on dandelion plants as an alternative source for natural rubber. “Not everybody (tyre company) is willing to invest in the early research of dandelion rubber and setting up the entire bio-economy. You have to establish a full value chain from breeding to the production of natural rubber from dandelion plants, which is does not exist yet and not every market player is willing to invest in such a long-term process,” explains Dr Recker.

Since Continental sees dandelion a sustaining resource for natural rubber in the future, it has made a substantial investment for the project. It has already poured in 35 million euros for the project. “Though many of our peers are investing in other resources to get natural rubber, I think we are quite unique investing like the way we are to explore alternative resources for natural rubber,” says Dr Venz.

Over 90 percent of natural rubber derives from South East Asia, a tropical region suitable for natural rubber trees. However, erratic climate behaviour is hitting production of natural rubber in this region. Natural rubber producers are also exploring other areas to grow natural rubber trees. According to Dr Recker, the research project has yet to ascertain the survival scope of the Russian dandelion in changing climates. “I believe that Dandelion will grow in all climate zones,” says Dr Recker.

Yield ratio

As of now, Continental also does not have comparable yield ratios between natural rubber from dandelion and hevea brasiliensis. “We are working on determining the output of natural rubber per acre from both resources,” says Dr Venz. “Usually, between 1 and 1.8 ton per hectare per year is produced from rubber trees, and around the same amount of production per hectare we are expecting from dandelion plants,” estimates Dr Recker.

As part of the value chain creation, the company is focusing on breeding for seed production and harvesting, root production and harvesting, and the extraction process. According to the company, growers also need some time to understand and get hands-on to harvest dandelion plants. Every year climate conditions will determine a different impact on the plants. “We will need to see how the crops will react in different climate and harvesting seasons. We are building a network of farmers in North East Germany from whom we learn and whom we can teach what we have learned,” added Dr Recker.

Fundamental design and development of tires for the mobility of the future will be unchanged; however, tires will be expected to be high performance and eco-friendly. According to Continental executives, for the mobility of the future, natural rubber will remain the core ingredient and dandelion will be one of the sustainable options to provide natural rubber. “Rubber be will be used in future to make high-performance tires, and we are exploring the option to have a sustainable source for natural rubber,” adds Dr Recker.

Hankook Prepares For Extreme Grip Variations At WRC Croatia Rally 2026

Hankook Tire, the exclusive tyre supplier for the FIA World Rally Championship, will face the demanding Croatia Rally from 9 to 12 April 2026. This event marks round four of the season and takes place in and around the port city of Rijeka. Among the most gruelling rallies on the calendar, it will feature both the Ventus Z215, engineered for precise dry handling and cornering stability, and the Ventus Z210, designed to deliver superior traction and rapid water evacuation in wet and unpredictable conditions.

The 2026 route spans roughly 300.28 kilometres across 20 special stages, with the service park relocated to the historic Grobnik Circuit. The course covers four counties, including shakedown stages on the island of Krk and technical tests through the Lika-Senj highlands. Drivers must contend with extreme grip variations along the Adriatic coast, from abrasive volcanic tarmac in the mountains to smoother, dustier sections near the sea, the latter becoming dangerously slick with even light rain.

Throughout the event, Hankook will operate its Brand World marketing booth inside the service park, reinforcing its unified global premium image. The booth will offer interactive experiences such as a motorsports history zone, racing simulator, tyre fitting activities, merchandise sales and a photo zone, giving fans an immersive brand encounter. Meanwhile, intense competition is expected: while Toyota GAZOO Racing has a strong history in Croatia, both Hyundai Shell Mobis World Rally Team and M-Sport Ford World Rally Team aim to exploit the new coastal terrain to challenge for the podium.

Bridgestone To Showcase Lunar Rover Tyres At 41st Space Symposium

Bridgestone has announced its participation in the 41st Space Symposium, the largest space conference in United States, taking place in Colorado Springs from 13 to 16 April 2026. The company’s exhibit will be hosted within the Japanese Space Industry pavilion organised by Japan Aerospace Exploration Agency (JAXA), marking its third consecutive year at the event since 2024. A key focus of Bridgestone’s presence is its ongoing development of lunar rover tyres, a project that embodies the company’s belief that ‘tyres carry life’.

Since 2019, Bridgestone has advanced research on lunar rover tyres and pursued co-creation with international partners to commercialise space mobility technology. In 2024, the company collaborated with Astrobotic Technology, followed by a basic agreement with ispace in 2025. These efforts aim to generate new value in the rapidly evolving space mobility sector.

At the symposium, Bridgestone will demonstrate tyres for small and medium lunar rovers, first unveiled in 2025, by mounting them on a mobility vehicle. Attendees can see and touch the tyres, experiencing their high traversability on simulated lunar challenges like fine sand and rocky ground. Through this showcase, Bridgestone seeks to expand its space business network and foster co-creation opportunities, ultimately supporting safe lunar mobility and humanity’s exploration goals.

The lunar rover tyre project applies Bridgestone’s AirFree technology, an exploratory business under its 2024–2026 Mid Term Business Plan.
