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 is all set for the showdown at Fuji Speedway this weekend for the sixth round of the FIA World Endurance Championship, equipping all 18 LMGT3 cars with the Goodyear Racing Eagle tyres . The Japanese venue ranks among the calendar’s fastest and most demanding circuits.

Its permanent-track straight measures 1.475 km, the longest of the season. That extended run from Turn 16 to Turn 1 allows front tyres to cool substantially before subsequent corners impose heavy lateral and longitudinal loads on the rear tyres, making temperature management critical over the six-hour race.

Every LMGT3 entrant will use the Goodyear Racing Eagle Medium compound, the same specification employed in the opening five rounds. It was engineered for a broad range of circuits and temperatures, suiting Fuji’s famously changeable conditions. Goodyear Racing Eagle Wet tyres remain available should rain arrive.

The Medium compound could enable single-stint strategies, prioritising performance from each set over multi-stint approaches, with Fuji’s relatively low wear potentially permitting extended runs when safety car or full course yellow periods make that advantageous. Tyre selection and pit timing gain added importance given swiftly shifting weather. Goodyear Racing Eagles also compete this weekend at Kansas Speedway in NASCAR, Rockingham Dragway in NHRA and Silverstone in the British Touring Car Championship.

Stephen Bickley, Goodyear Endurance Program Manager, said, “Fuji’s track surface is relatively smooth, meaning overall wear is comparatively low. This also means that managing heat and bringing the tyres up to temperature can be more difficult, particularly at the start of a stint. Teams need to get the tyres into their operating window quickly, and the quick warm-up characteristics of the Goodyear Racing Eagle Medium will help them do that.

“The weather can be a major factor at Fuji, so teams need to be prepared to react quickly. The wide operating window of the Goodyear Racing Eagle Medium gives drivers confidence across changing temperatures, while the Goodyear Racing Eagle Wet provides a solution should track running become affected by rain.”

TyreSafe has entered a new partnership with South Yorkshire Fire & Rescue, reinforcing joint efforts to prevent road casualties and enhance safety throughout the county. The fire and rescue service becomes part of a widening group of UK fire services collaborating with TyreSafe to highlight the dangers linked to illegal and poorly maintained tyres.

Under the arrangement, both organisations will pool expertise, resources and engagement opportunities to promote tyre safety among South Yorkshire road users. This work will be integrated into broader road safety initiatives. The partnership also builds on South Yorkshire Fire and Rescue’s existing role within the South Yorkshire Safer Roads Partnership, where education, training and publicity are central to reducing casualties.

The collaboration comes amid a difficult road safety picture. In 2024, a total of 43 people died and 748 were seriously injured in South Yorkshire collisions, amounting to 791 killed or seriously injured casualties. Although this was lower than the 841 recorded in 2023, the South Yorkshire Safer Roads Partnership acknowledges substantial progress is still needed to reach its Vision Zero goal.

Road traffic collisions remain a major operational demand for South Yorkshire Fire and Rescue, whose community risk work involves joint efforts to cut incident numbers and severity. Serious and fatal crashes occur on major routes linking Sheffield, Doncaster, Rotherham and Barnsley, and on higher-speed rural roads. Tyres are vital to the Safe System approach, as defects can impair braking, steering and control, raising the risk of serious incidents.

Stuart Lovatt, Chairman, TyreSafe, said, “Fire and rescue services see the consequences of serious road collisions first-hand. Their experience gives them a unique perspective on the importance of prevention, and that makes South Yorkshire Fire and Rescue an incredibly valuable partner for TyreSafe. South Yorkshire has a strong and established road safety partnership, with organisations already working together towards Vision Zero. We want to complement that work by making tyre safety a more visible part of the conversation around safer vehicles and safer roads. We’re delighted to welcome South Yorkshire Fire and Rescue to the growing number of fire and rescue services partnering with TyreSafe. By combining their frontline experience and local reach with our specialist knowledge of tyre safety, we have an opportunity to reach more drivers with simple, practical advice that could help prevent a serious collision.”

Robert Horne, Prevention & Intervention Officer for Barnsley, said, “We are pleased to be partnering with TyreSafe to strengthen the road safety work we already undertake with our partners across South Yorkshire. Our firefighters regularly attend road traffic collisions and see the devastating impact they can have on individuals, families and communities. Prevention is therefore a vital part of our role, and helping people understand the simple steps they can take to reduce risk is an important part of that work. Tyres are a critical safety component on every vehicle, yet they can easily be overlooked. Working with TyreSafe will help us reinforce that message and provide road users with practical information they can use to make sure their vehicles are safe and roadworthy.”

Yokohama Rubber has become a participant in PROJECT TREE, a sustainability initiative launched by ITOCHU Corporation to advance the responsible sourcing of natural rubber. The programme relies on blockchain technology to create a traceable supply chain, and Yokohama Rubber has begun using rubber procured through this framework. On 25 September 2026, the company started supplying tyres for commercial vehicles operated by FamilyMart Co., Ltd. as project-supported products.

Natural rubber represents roughly 30 percent of tyre raw materials, while tyres account for about 70 percent of global consumption of the resource. Most of the world’s supply comes from smallholder farmers in nations such as Thailand and Indonesia. The tyre industry has responded with efforts spanning forest conservation, human rights safeguards, agricultural training and livelihood stabilisation. PROJECT TREE identifies sourcing regions and assists farmers through incentives from participating companies and training programmes.

Yokohama Rubber has pursued traceability through several channels. Its natural rubber processing subsidiary, Y.T. Rubber Co., Ltd., earned Chain of Custody certification from the Forest Stewardship Council for responsible processing and distribution. The company also employs RubberWay Geo-Mapping as a risk assessment tool and is aligning its operations with the EU Deforestation Regulation (EUDR). For several years it has supported smallholder farmers in Thailand’s Surat Thani Province. Joining PROJECT TREE is expected to further reinforce supply chain transparency and supplier support.

As a founding member of the Global Platform for Sustainable Natural Rubber (GPSNR), Yokohama Rubber revised its Procurement Policy for Sustainable Natural Rubber in September 2021 and continues to strengthen collaboration with the platform. The company is also working towards the United Nations Sustainable Development Goals, with the Yokohama Rubber Group promoting sustainable raw material procurement, including natural rubber, as part of that effort.

Liberty Tire Recycling took part in a Washington State Tire Amnesty Event alongside the Washington State Department of Ecology and the Lewis County Solid Waste Utility. The three-day event, held in mid-September at the Southwest Washington Fairgrounds in Centralia, marked the area’s first such opportunity in nearly two and a half years. Local turnout surpassed expectations, with more than 240 tonnes of tyres and wheels gathered from area residents.

Handling that volume demanded close coordination between Liberty Tire Recycling's facilities in Puyallup, Washington and Portland, Oregon. Crews from both sites merged staff, equipment and other resources to keep processing on track. Lewis County residents showed up in numbers, forming lines of vehicles before the gates opened each morning. Numerous participants seized the chance to rid their properties of unwanted tyres and satisfy local cleanup and code compliance rules, which boosted neighbourhood appearance, cut environmental dangers and made communities safer.

The scale of the response made clear how much amnesty events matter in giving residents a handy, responsible way to part with old tyres while discouraging illegal dumping. The occasion also marked the debut of Liberty Tire Recycling's new regional outreach booth. Staff gave out educational materials and stickers and explained the journey tires take after collection. Attendees learned how recycled tyres find new life in transportation, construction, landscaping, sports surfaces and other uses, and feedback was overwhelmingly favourable.

None of this would have come together without solid collaboration among community partners. Liberty Tire Recycling thanked Lewis County residents, the Lewis County Solid Waste Utility and the Washington State Department of Ecology for their commitment to responsible tyre management and environmental stewardship. The company also recognised its Portland team and every employee who pitched in on planning, logistics, transportation and processing. The event ended up as Liberty Tire Recycling's largest amnesty collection of the year, showing both the need for accessible tyre recycling and the community's commitment to sustainability. By steering discarded tyres away from illegal dumping sites and landfills, the company keeps supporting healthier communities and a more circular economy, and it looks forward to future collection events across the Pacific Northwest.
