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.

TyreSafe, UK’s leading tyre safety charity, has launched its annual Tyre Safety Month by cautioning UK motorists that confidence in their vehicles’ stopping ability may be misplaced. Research indicates that although 83 percent of drivers feel fully in control of stopping distances, merely 6 percent know the additional distance required to halt in wet conditions at motorway speeds.

The study reveals that 94 percent of drivers underestimate how sharply stopping distances grow in rain, with many erring by substantial margins. This mismatch between perceived and actual risk spans every UK region, pointing to a nationwide problem involving driver awareness and vehicle preparedness.

In response, TyreSafe advises routine tyre checks, especially before seasonal shifts and heavier rainfall. Motorists are urged to remember the ACT principle – air pressure, condition and tread depth – and to act before they react.

Stuart Lovatt, Chairman, TyreSafe, said, “Many drivers and riders believe they are in control – but that confidence is often misplaced. Stopping distances in wet conditions can be far greater than expected, and tyres play a critical role in that equation. If your tyres are not properly maintained, your ability to stop safely is significantly reduced – no matter how confident you feel behind the wheel.”

Scandinavian Enviro Systems AB (publ) has secured a second extension of its company reorganisation, with the Gothenburg District Court approving a further three-month period lasting until 27 November 2026. The company has been under reorganisation since 27 February 2026, when the court initially granted the process. An earlier extension had already pushed the deadline to 27 August 2026 before this latest decision.

In its ruling, the District Court noted that Enviro has submitted a draft reconstruction plan and secured the necessary financing for it. The court also found that the company has taken other required measures, leading it to conclude that exceptional grounds exist to justify continuing the reorganisation beyond the ordinary timeframe.

Enviro now plans to ask the court to order plan negotiations and schedule a plan hearing as soon as possible. At that hearing, affected parties will be placed into groups and permitted to vote on whether to adopt the reorganisation plan. Details of the hearing date and participation instructions will be announced via press release and the company's website. Unless plan negotiations are ordered earlier, a reorganisation may last at most one year, or 15 months from the initial decision in such cases.

Fredrik Aaben, CEO, Enviro, said, "The District Court's decision gives us the opportunity to continue the intensive work of completing the company reorganisation. We have taken several important steps forward and are now working purposefully to establish a strong and long-term sustainable Scandinavian Enviro Systems. The strong interest in Enviro's technology persists, both with regard to licensing and other forms of collaboration. We are firmly committed to completing the reorganisation and building a strong industrial company based on our world-leading technology.”

Continental has launched the Conti HSR 5 EP steer tyre and Conti HDR 5 EP drive tyre, expanding its Generation 5 regional haul lineup. Engineered for regional fleet operations, both products target greater mileage, better fuel economy and longer casing life, aiming to lower fleets’ total cost of ownership.

The tyres suit routes marked by frequent stops and starts, urban and suburban travel and changing road surfaces. Their advanced tread patterns and latest compound technology seek a balance among wear performance, rolling resistance and retreadability while supporting year-round operation.

For the steer position, the Conti HSR 5 EP uses a new five-rib tread pattern and optimised footprint to improve wear and promote even treadwear. With Continental’s Generation 5 compound, it offers an estimated 22 percent mileage gain over its predecessor while keeping rolling resistance low for fuel efficiency.

The Conti HDR 5 EP drive tyre combines an open shoulder design, enhanced stone-trapping resistance and better cut-and-chip protection to preserve casing integrity and retread potential. It delivers an estimated 19 percent removal mileage improvement over its predecessor while maintaining fuel-saving rolling resistance. Both tyres are available from October 2026 in key regional haul sizes, with more sizes planned during 2027.

Shaun Uys, Vice President Marketing and Sales, Truck Tires US, said, "Regional fleets continue to face mounting pressure to improve operating efficiency while controlling costs. The new Conti HSR 5 EP and Conti HDR 5 EP were developed to help fleets go farther on every tyre investment through increased removal mileage, lower fuel consumption and enhanced casing life."

In addition, a cross-divisional Sustainable Natural Rubber (SNR) Subcommittee will be launched to manage and reduce risks and create opportunities in the natural rubber supply chain. Natural rubber is a natural capital resource on which the Group’s business significantly depends and also has significant impacts. The subcommittee will address these issues from natural capital and human rights perspectives, based on the Sustainable Natural Rubber Policy.

The SNR Subcommittee will serve as a cross-functional body that concentrates and accelerates the Group’s various SNR activities. By aligning with biodiversity and human rights initiatives and taking a mid- to long-term approach, it will pursue sustainable natural rubber through efforts such as supporting natural rubber farmers and collaborating with external partners.
