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.

Bridgestone India has joined hands with Sagest (Society for Environment and Agricultural Sustainability) to launch the Nutritional Fruit Orchard Project in Sulawad Village, Madhya Pradesh. This women-led project improves nutrition, fosters livelihood possibilities and supports environmental sustainability. With the help of Bridgestone staff and locals, the orchard, which spans four acres, is home to more than 1,300 fruit trees of more than 15 species. It is grown using sustainable practices.

With a 96 percent survival rate in its first year, the project has enabled women to run a nursery with 1,000 saplings and turn garden waste into organic compost and insecticides, encouraging environmentally responsible farming and generating extra revenue. The ladies who are in charge of the orchard will have a reliable source of income once it is completely developed. By assisting households in growing 251 kitchen gardens, the programme also improves nutrition in Sulawad by guaranteeing that locals have access to fresh, homegrown produce. Frequent training sessions have improved environmental consciousness and community ownership.

This unique project demonstrates multi-stakeholder collaboration – Bridgestone and Sagest lead implementation, the local panchayat provided land, women manage daily operations and a nearby government school assists. By combining environmental conservation, rural development and women’s empowerment, the initiative serves as a replicable model for sustainable corporate-community partnerships.

Hiroshi Yoshizane, Managing Director, Bridgestone India, said, “True sustainability goes beyond business – it’s about empowering communities and protecting the planet. This project shows how women-led, community-driven action can create long-term impact on nutrition, livelihoods and the environment. It’s not just about planting trees; it’s about planting hope, resilience and a better future. This initiative beautifully demonstrates how community-driven, women-led environmental action can improve nutrition, generate income and protect the planet – all at the same time.”

Nynas, with its strong commitment to innovation and product sustainability, recently commissioned an independent study to evaluate the environmental impact of its products across four key application areas: transformer oils, lubricating greases, tyres and bitumen binders. Conducted by Future Earth Analytics, LLC, the research revealed that many Nynas products deliver significant sustainability advantages, often surpassing industry performance benchmarks.

The study highlighted several environmental benefits across different applications. In transformer oils, certain Nynas products improve cooling efficiency and energy transmission, reducing energy losses during operation. For tyres, specific Nynas tyre oils contribute to lower rolling resistance, which helps decrease fuel consumption in vehicles. In lubricating greases, the use of naphthenic base oils reduces reliance on lithium – a resource-intensive material – while also cutting energy consumption during production. Additionally, Nynas’ strategic location near bitumen customers minimises transportation distances, thereby lowering associated emissions.

The findings underscore a substantial environmental impact: had customers opted for alternative products instead of Nynas’ offerings in 2023, an additional 740,000 tonnes of greenhouse gas emissions would have been generated. This saving is equivalent to avoiding the consumption of five million barrels of oil.

To assess these benefits, researchers employed a dual analytical framework combining Life Cycle Assessment (LCA) and Net Energy Analysis (NEA). This approach allowed for a detailed comparison of energy savings and emissions reductions across different lifecycle phases, such as cradle-to-gate and use-phase impacts. By focusing on stages where variations occur, the study provided a quantitative evaluation of how choosing Nynas products can lead to measurable energy and emissions savings compared to market alternatives. The results reinforce Nynas’ leadership in delivering sustainable solutions that support a lower-carbon future. 

Marika Rangstedt, Sustainability Manager, said, “The beneficial effects are true not only for our recent circular or renewable products, but also for many of our traditional products. We are leading the way in sustainability and setting new standards for product related environmental responsibility within our industry.”

Westlake Performance Tyres, a brand of ZC Rubber, has teamed up with German motorsport team Red Bull Driftbrothers as the new official supplier and tyre partner. The company will supply its Westlake Sport RS tyres for the team’s two 1,000 hp BMW M4s.

Munich marketing agency die agentour was the driving force behind the collaboration. The Red Bull Driftbrothers and ZC Rubber have a long-term cooperation that benefits both parties in many ways. Giving the team tyres will help with technical advancements based on driver Elias Hountondji's input, among other things. The collaboration will also help ZC Rubber spread the word about the Westlake brand throughout the European market. Demonstrating the products' and technologies' performance and quality in harsh environments is also a clear signal to the European OEM and replacement market.

This year's ADAC RAVENOL 24h Nürburgring marked the debut of the new collaboration. The Red Bull Driftbrothers created a stir among the record-breaking audience when they performed a display drift in their recently tyred BMW vehicles during the pre-race of the renowned race. The Westlake Sport RS tires were especially taxed by the high track temperatures.

Henry Shen, Deputy General Manager, Zhongce Rubber Group (ZC Rubber), said, “We’re proud to be the tyre partner of Red Bull Driftbrothers. Their trust in WESTLAKE, especially the performance of our SPORT RS on the demanding drift circuit, is a powerful endorsement.
