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.

Goodyear executed its largest-ever endurance operation at the 24 Hours of Le Mans, a feat defined by 188,747 kilometres driven, 377.5 million wheel revolutions, and 44 cars competing across the LMGT3 and LMP2 classes. The Goodyear Racing Eagle tyres delivered relentless performance, supported by over 120 experts and a stock of 8,000 tyres that sustained racing throughout the entire week.

The tyres' exceptional consistency allowed teams to extend stint lengths significantly, saving precious time during pit stops. Most LMGT3 squads completed four stints, or forty laps, before changing rubber, while LMP2 entries routinely managed five. One LMP2 team notably kept a single set for 56 laps, covering 761 kilometres, a distance comparable to travelling from Le Mans to Monaco.

Pace did not diminish despite the high mileage, with the fastest LMGT3 car posting a 100-lap average 1.2 seconds quicker per lap than the previous year, marking the fastest Le Mans of the LMGT3 era. Goodyear’s off-track presence was equally robust, featuring the Goodyear Blimp, a new grandstand, a popular fan activation, a museum collaboration and the introduction of the Goodyear Passerelle.

Ahead of the race, Goodyear reaffirmed its commitment to LMGT3 through a joint announcement with the FIA and ACO, extending its exclusive supply into a fourth season in 2027 with a new tyre composed of 66 percent sustainable materials. The WEC now moves to the 6 Hours of São Paulo on 12 July, though many Le Mans teams will first compete at the European Le Mans Series’ 4 Hours of Imola on 5 July.

Stephen Bickley, Goodyear Endurance Program Manager, said, “When you look at the distances covered without compromising on pace, it underlines the consistency and reliability of our Goodyear Racing Eagle tyres throughout one of the toughest races in the world. It was a special Le Mans for us, felt through our fan activation, partnership renewal and icons old and new at – and above – the circuit.”

The Tire Industry Project (TIP) has initiated a pilot study in collaboration with the Greater Paris Sanitation Authority (SIAAP) and the sustainability consultancy ERM to assess the potential of wastewater treatment plants to remove tyre and road wear particles. The research is being conducted at the Valenton wastewater treatment facility near Paris, which ranks as Europe’s second-largest plant and features advanced treatment technologies representative of modern municipal systems. This investigation is scheduled to continue through 2026.

In numerous urban centres globally, stormwater and road runoff are channelled into wastewater systems prior to being discharged into natural waterways. A clearer understanding of how effectively these treatment processes capture TRWP could guide the broader adoption of optimised wastewater management practices. Currently, systematic data quantifying the removal of these particles within treatment plants remains scarce, and this project aims to generate comprehensive, end-to-end evidence to bridge that knowledge deficit.

The study represents TIP’s first real-world application of a priority mitigation strategy identified in its white paper on addressing tire and road wear particles. Over the coming months, researchers will collect and analyse samples from key stages of the Valenton plant’s treatment cycle using advanced pyrolysis gas chromatography-mass spectrometry. The findings are expected to estimate the total removal efficiency across the entire process and will be submitted to a scientific journal, with publication anticipated in early 2027.

The scientific understanding of TRWP is complicated by a lack of standardised methodologies, the variable nature of the particles and their transformation products, and the diverse environmental pathways they traverse. In response, TIP and its member companies have committed to advancing research on quantification, characterisation, environmental migration and potential impacts while collaborating with value-chain stakeholders to support science-based interventions. A 2024 TIP publication reviewed over 50 mitigation measures and prioritised nine based on upstream and downstream potential, employing a prevention, containment and removal framework.

That review also concluded that no single measure has been proven effective specifically for TRWP and that on-ground validation is essential. Moreover, the paper stressed that no universal solution exists, requiring coordinated, large-scale implementation across multiple actors, including the tyre, road construction and automotive sectors, as well as municipal authorities, academia and other public and private entities. The Valenton pilot thus marks TIP’s inaugural effort to test wastewater management’s real-world efficacy, uniting diverse stakeholders from both the public and private sectors in this critical research.

Larisa Kryachkova, Executive Director, TIP, said, “This pilot is an important step in going beyond understanding the subject in the laboratory to field-based evidence. We expect to identify best practices that can be applied far beyond this project, supporting TIP’s ambition to support science-based mitigation.”

Sabrina Guérin, Head of Innovation Department, SIAAP, said, “As the public authority responsible for wastewater treatment in the Paris region, SIAAP is committed to emerging science that protects waterways. By taking part in this TIP study, we will gain an early, science-based view of TRWP movement in solid waste. The findings can help inform and accompany future treatment planning and readiness for upcoming regulatory requirements.”
