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.

DUNLOP Unveils Blue Response TG, Marking New Chapter Under Sumitomo Rubber

DUNLOP Unveils Blue Response TG, Marking New Chapter Under Sumitomo Rubber

DUNLOP has announced the launch of its BLUE RESPONSE TG, a new premium summer tyre developed for passenger cars and SUVs. Suitable for internal combustion, hybrid and electric vehicles, the tyre will be available in 99 sizes spanning 15 to 21 inches, series 40-65 with H, V and W speed ratings. Production takes place at a state-of-the-art facility in Türkiye, with European market availability scheduled for March 2026.

This launch represents a significant shift for the brand in Europe. BLUE RESPONSE TG is the first DUNLOP product developed under Sumitomo Rubber Industries (SRI) since it acquired the historic brand’s passenger car tyre rights in 2025. The tyre was engineered collaboratively by DUNLOP’s teams in Germany and Japan, drawing upon SRI’s established manufacturing and development capabilities.

The ‘TG’ designation stands for ‘Touring,’ underscoring the tyre’s ability to deliver long-distance comfort and efficiency while maintaining strong performance. A suite of new technologies ensures stability and control on both wet and dry roads. Impressive braking performance is a key feature, enhancing overall safety and driver confidence.

Central to the tyre’s capabilities is an intelligent three-zone rib design that efficiently channels water away from the contact patch. This promotes stability at higher speeds and unlocks reliable wet-weather grip during directional changes. A refined shoulder design features lateral grooves set at optimised angles. This enhances tread rigidity, reduces block deformation under load and ensures consistent force transfer when cornering and braking.

Durability is addressed through a new tread compound utilising longer, more resilient polymer chains. These resist abrasion and slow wear to extend mileage without compromising performance. To complete the package, a noise-reducing tread design links lateral grooves into continuous channels. This smooths airflow and dampens vibration, resulting in a noticeably quieter cabin environment and the composed, refined ride expected from the DUNLOP brand.

George Russell Honoured With Pirelli Sprint Qualifying Award After Shanghai Pole

George Russell Honoured With Pirelli Sprint Qualifying Award After Shanghai Pole

The first Sprint weekend of the 2026 Formula 1 season began in China with an intense schedule, starting with Sprint Qualifying on Friday. George Russell claimed pole position, finishing over two-tenths of a second ahead of his teammate Kimi Antonelli, with Lando Norris securing third. Russell received the Pirelli Sprint Qualifying Award from Dario Marrafuschi, Pirelli Motorsport Director. The prize includes a helmet decorated in the colours of the Chinese flag and a replica Pirelli P Zero Soft tyre, both personalised with the driver’s name and number.

Pirelli’s compound regulations shaped the qualifying format. In SQ1 and SQ2, drivers were required to use a set of medium tyres, with most completing two fast laps per segment. For the final SQ3 shootout, the top 10 switched to the soft compound. Russell’s pole time of 1:31.520 came on the red-walled P Zero Soft, less than seven-tenths slower than the 2025 sprint pole time of 1:30.849, set by Lewis Hamilton.

The F1 Academy also opened its season in Shanghai, with Alisha Palmowski setting the fastest time in Friday’s qualifying. She outpaced Alba Larsen and Emma Felbermayr ahead of the series’ two races scheduled for Saturday and Sunday.

Marrafuschi said, “During Sprint race weekends, it’s always challenging for teams to fully assess tyre behaviour as they only have one hour of free practice. During this session, the teams used one set of medium tyres and one set of soft tyres, without carrying out any significant long runs. The hards were saved for the following days, and some teams may consider using them in their strategies for Sunday's race as early as tomorrow.

“The Sprint race, which is most likely to be run on Medium tyres, will certainly provide a clearer picture. The performance difference between the two compounds used on Friday is around six tenths. Interestingly, in the first two qualifying segments, the C3 was once again able to deliver maximum performance on the second push lap after completing a cooldown lap.

“Temperatures are cooler than last year; the track is still dirty and has less grip than we will see on Sunday as the track evolves. As happened last year and as expected, some graining appeared on the front-left tyre, which is the most stressed by Shanghai’s corners, and to a lesser extent on the front-right, although the impact on overall wear remains limited. On this circuit, teams tend to prioritise protecting the front axle, shifting the balance towards the rear as much as possible.”
