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.

Continental played a decisive role in the world record achieved by Volkswagen's Mission Efficiency concept vehicle, supplying a specially developed concept tyre. During the drive, the near-production electric vehicle consumed just 7.51 kilowatt-hours per 100 kilometres including charging losses, or 6.89 kWh excluding them. The RID – Rekord-Institut für Deutschland certified the result on 24 August 2026, after a 1,278.36-km journey from Wolfsburg to Vienna under real-world conditions. The trip required only one charging stop and ended with 164 kilometres of remaining range.

The concept tyre achieves a rolling resistance of 4.9 kg per metric tonne, roughly 25 percent below the threshold for the EU tyre label's highest Class A rating. Because about one-fifth of an electric vehicle's propulsion energy is consumed by overcoming tyre rolling resistance, this reduction is a major factor in extending range. Tyres therefore directly influence energy consumption and the distance possible on a single battery charge.

Rolling resistance arises because a tyre deforms each time it contacts the road during every revolution. That deformation draws energy otherwise used for propulsion, and around 20 percent of an electric vehicle's battery energy is spent merely to overcome this effect. Continental's concept tyre builds on the EcoContact 7, a production tyre already known for exceptionally low rolling resistance.

For the record drive, the tyre was modified to Volkswagen's specifications, producing a design that deforms even less as it rolls, cutting energy consumption further and increasing range per charge. Two elements proved especially important. The sidewall follows the same design principle used in the EcoContact 7, delivering stability without raising rolling resistance. Meanwhile, the tread compound was specially tailored to the tyre's other components, working alongside the carcass and tread pattern to minimise energy losses.

An additional advantage came from a new manufacturing process. During production, the initially soft green tyre is hardened in a mould under heat and pressure through vulcanisation, but Continental did not heat it uniformly as in conventional production. Instead, different areas were exposed to different temperatures, with the tread cured differently from the sidewall. This allowed each zone's properties to be optimised more precisely, resulting in even lower rolling resistance for the tread.

Rolling noise also shaped the tyre's development, and its tread pattern was specifically designed to achieve particularly low noise levels. Engineers varied the spacing and angles of the tread blocks so that the noises they generate partially overlap and cancel each other out, following a principle similar to noise-cancelling headphones. For the Mission Efficiency vehicle, this means the tyre improves efficiency while also ensuring a notably quiet driving experience, an aspect of growing importance because tyre noise becomes far more noticeable without an internal combustion engine.

The ID. Polo production car on which the Mission Efficiency is based already comes fitted with Continental's EcoContact 7 as standard, but the record project took the two companies further. Continental developed the tyre in close collaboration with Volkswagen's vehicle and aerodynamics engineers from a very early stage. The collaboration extended into the vehicle's design, with the tyre's colour-accented sidewall incorporating styling elements from the concept.

During the record drive, the vehicle set three benchmarks: the world's most aerodynamic near-production vehicle with a drag coefficient of 0.158, the most efficient four-seat electric vehicle in its class in a single controlled drive and the most economical near-production four-seat electric vehicle on an officially documented long-distance real-world drive. Largely based on production components from the ID. Polo, including its battery and drivetrain, the Mission Efficiency demonstrates the efficiency gains possible through targeted improvements to existing electric-vehicle technologies.

Dr Christian Strübel, Continental’s expert in rolling resistance for passenger-car tyres, said, “The record shows that increasing the range of electric cars does not necessarily require larger batteries. Significant opportunities lie in the successful interaction of all vehicle components. Tyres make a crucial contribution. Together with Volkswagen, we’ve demonstrated what’s possible when vehicle, aerodynamics and tyre development are aligned from the very beginning.”
