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 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.

Continental has earned top recognition in the ‘Tires and Tire Management’ category of the International busplaner Sustainability Award for its Conti Urban HA 5 NXT tyre. The award celebrates groundbreaking vehicle parts, services and models that drive sustainability in the bus industry. Announced on the evening before the BUS2BUS trade fair, this marks the fourth time Continental has received this honour since the prize was first introduced.

A key feature of the Conti Urban HA 5 NXT is its material composition, with up to 60 percent coming from renewable, recycled or ISCC mass balance-certified sources. ISCC certification ensures full traceability of these raw materials across the supply chain. An externally verified life cycle assessment shows an 11 percent drop in greenhouse gas emissions compared to the earlier Conti Urban HA 3 model. The tyre incorporates natural rubber, renewable fillers, recycled synthetic rubber and rubber derived from mechanically processed end-of-life tyres.

Designed to address major trends reshaping urban transport such as urbanisation, electric mobility and digital fleet management, the tyre arrives at a time of strong growth in new bus registrations across the EU, especially in Germany and Poland. Electric bus adoption is rising sharply in markets like Germany, Sweden and Belgium, while conventional technologies lose ground. This shift underscores the need for tyres that support cleaner, more efficient city bus operations.

The Conti Urban HA 5 NXT delivers a 25 percent reduction in rolling resistance versus the prior generation, which can extend electric bus range by up to 15 percent. A new tread compound increases mileage by up to 15 percent compared to the Conti Urban HA 3 while maintaining a B EU wet‑grip label rating. A reinforced sidewall enhances resistance against curb and impact damage, and the optimised tread pattern improves traction and lowers noise, boosting passenger comfort.

The tyre works seamlessly with Continental’s digital ContiConnect system, allowing fleet operators to monitor pressure, temperature and wear in real time using sensors. This enables proactive maintenance, greater operational safety, fewer unplanned breakdowns and cost-effective fleet management. Since its launch in 2013, the International busplaner Sustainability Award has become one of Europe’s most respected honours in bus and transport, recognising companies that balance economic success with environmental care and social responsibility.

Scandinavian Enviro Systems AB (publ) (Enviro) has been informed that Infiniteria Sweden AB and Infiniteria Europe Sàrl plan to ask the Gothenburg District Court to immediately end Enviro’s ongoing company reorganisation. Infiniteria also challenges the legality of Enviro’s recent contract cancellations regarding their joint venture and has indicated it will seek damages as a result.

The reorganisation was originally approved by the same court on 27 February 2026. Infiniteria now argues that the process should be halted at once because its intended purpose is unlikely to be achieved and because continuing would be unfair to Infiniteria. Furthermore, Infiniteria has made clear it will oppose any reorganisation plan that Enviro might put forward.

Infiniteria disputes the validity of Enviro’s termination of their joint venture agreements, which occurred on 20 March 2026 under the Swedish Company Reorganization Act. While no formal damages claim has been filed yet, Infiniteria preliminarily estimates potential claims from the terminations at roughly EUR 84 million. This estimate partially overlaps with an existing arbitration claim against Enviro that was disclosed on 6 February 2026.

Enviro firmly rejects Infiniteria’s stance, asserting that its conclusions rest on incomplete and incorrect information, making them unfounded. Together with its legal advisors and the court-appointed administrator, Enviro is reviewing the matter and will respond to Infiniteria’s claims as directed by the District Court.
