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.

Firestone, a Bridgestone Americas subsidiary, has introduced the Firestone Pathway AS, an all-season touring tyre built for everyday drivers. It comes in 73 sizes, giving it the widest vehicle coverage of any Firestone tyre, and pairs dependable performance and long tread life with value, all backed by a 65,000-mile limited mileage warranty.

Development was shaped heavily by consumer feedback, which pushed improvements in wet traction, tread life and ride comfort over the predecessor. The original plan called for 48 sizes, but 25 more were added mid-development to broaden market reach, helping Firestone cover nearly 77 percent of registered vehicles.

A tread compound engineered for longevity, additional sipes and an optimised see-through void promote even wear and sustained traction. Deep interlocking 3D sipes deliver grip from light snow to dry and wet pavement. Internal testing recorded wet braking gains of 18 percent against the Uniroyal Laredo HT, 11.7 percent against the Firestone All Season and 7.4 percent against the Toyo Extensa AS2, along with shorter dry braking than six leading rivals. Low rolling resistance also supports fuel efficiency in combustion-engine vehicles.

Nationwide availability is underway, with fitments covering popular models such as the Toyota Camry, Toyota RAV4, Subaru Outback, Jeep Grand Cherokee and Chevrolet Equinox.

Leslie Sawyer, Senior Product Design Engineer, Bridgestone Americas, said, "Most drivers want a tyre they can depend on. The Firestone Pathway AS is designed to deliver reliable performance and long-lasting value, giving drivers the confidence they need in everyday driving situations."

Scandinavian Enviro Systems AB (publ) has entered into a conditional service agreement with an international operator that provides transport services to the energy sector. The agreement follows a letter of intent signed by the two parties on 17 March 2026 and marks a further step towards establishing a tyre pyrolysis plant in North America. Using Enviro’s technology, the facility is intended to recycle up to 50,000 tonnes of end-of-life tyres annually.

Under the terms of the agreement, Enviro will produce the technical documentation needed for the plant’s permit applications and prepare an initial design for the entire facility. For these services, the company will receive a fixed fee of USD 2,000,000, corresponding to approximately SEK 19.5 million. The fee is divided between USD 500,000 for permit application work and USD 1,500,000 for plant design, with USD 450,000 payable once the customer decides to proceed and the remainder paid in instalments as various parts of the services are delivered. Additional work and technical support beyond the fixed-fee scope will be invoiced on an ongoing basis.

The start of Enviro’s work depends on the customer making a final decision to proceed with the project. That decision, in turn, requires the customer to have secured a site for the plant and to have entered into binding agreements with buyers of the plant’s two main products, oil and carbon black, covering at least 75 percent of expected production for each product. Should the customer neither decide to proceed by 31 December 2027 nor elect to continue, the agreement will terminate.

The assignment covers two principal deliverables: technical documentation required for environmental, planning and fire safety permit applications and an initial design of the whole plant, including drawings, equipment lists, calculations and technical specifications. The design will serve as the basis for more detailed engineering work before an investment decision. Enviro will also provide technical support during the permit application process for 12 months after delivering the permit documentation. The agreement does not grant any right to use Enviro’s technology to construct or operate the plant, which would require a separate licence agreement.

According to the timetable, the assignment is expected to be completed about seven months after the customer’s decision to proceed, with permit application documentation ready after roughly five months. The customer may terminate the assignment with 30 days’ notice, in which case Enviro is entitled to compensation for work performed and costs already incurred. Enviro remains entitled to compensation regardless of whether permits are granted or the plant is ultimately built. The agreement is described as an important step in Enviro’s strategy to establish technology-based plants internationally, with the design potentially forming the technical basis for a future licence agreement.

Fredrik Aaben, CEO, Enviro, said, “This is an important step towards establishing Enviro’s technology in North America. Together with the Customer, we are now moving from a letter of intent to a binding conditional agreement, and we look forward to designing the plant as soon as the project is ready to proceed.”
