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.

Hankook Tire, the exclusive tyre supplier to the FIA World Rally Championship (WRC), is supporting Round 5 of the 2026 WRC season, Rally Islas Canarias, taking place from 23 to 26 April across Spain’s Canary Islands. For the event, Hankook is providing its Ventus Z215 and Ventus Z210 tarmac rally tyres, with the former engineered for precise handling on abrasive asphalt and the latter designed for wet-road traction and water evacuation.

Celebrating its 50th anniversary in 2026, Rally Islas Canarias returned as an official WRC round for the second consecutive year after joining the calendar for the first time the previous season. Based on Gran Canaria Island, home to the capital Las Palmas, the rally featured 18 special stages covering a competitive distance of 322.61 kilometres, all on asphalt. The opening day’s highlight was the Super Special Stage at the BP Ultimate - Circuito Islas Canarias, where drivers competed in a head-to-head time-attack format.

Regarded as one of the championship’s most iconic tarmac events, the rally is defined by the abrasive, high-grip asphalt and dramatic elevation changes of Gran Canaria’s volcanic terrain. While the consistent surface grip allows circuit-like, high-speed precision driving, it also subjects tyres to intense physical stress. Maintaining grip under high surface temperatures and adapting to unpredictable mountain weather is expected to make tyre performance a decisive factor in the rally’s outcome.

Since the 2025 season, Hankook has served as the exclusive tyre supplier for all WRC classes, reinforcing its role as a key technical partner in global motorsport. By leveraging data from top-tier series such as the ABB FIA Formula E World Championship and the WRC, alongside advanced R&D infrastructure, Hankook continues to drive innovation in high-performance tyre technology while strengthening its global premium brand position.

Continental is providing comprehensive tyre support to Royal Den Hartogh Logistics, a Dutch family-owned leader in container-based bulk transport for the chemical and food industries. With a history of collaboration exceeding 60 years, the tyre manufacturer now supplies professional tyre management and rolling resistance optimised tyres from the Conti Eco Gen 5 family to the logistics firm’s European fleet of over 900 vehicles.

Peter Rodenburg, Senior Technical Manager at Den Hartogh, has identified safety, costs and the energy transition as the biggest challenges in the company’s Europe wide operations. His assessment highlights the need for more fuel-efficient driving and emission reductions. Meanwhile, Hinnerk Kaiser, Head of Product Development for Bus and Truck Tires at Continental, notes that the fifth generation of the Conti Eco tyre family is specifically designed to address transport sector customer needs and Europe’s dynamic regulatory environment.

The vehicle fleet operates across Europe with the latest generation tyres, supported by Continental’s Pull Point tyre monitoring, breakdown analysis and cost evaluation. Rodenburg has confirmed that the Eco tyre’s optimisation for rolling resistance delivers significant benefits in fuel efficiency and overall performance. The Conti Eco HD 5 has demonstrated its value in both fuel economy and mileage while also performing reliably under varying road and weather conditions.

Rodenburg has reported that after one year of joint fleet monitoring, the first impression of tyre performance and wear is positive. The switch to this tyre, combined with other vehicle optimisations, has yielded measurable cost savings. He states that with the complete package in place, the company has seen significant improvements in average fuel consumption of up to eight percent, making the move to the Conti Eco HD 5 a positive decision.

Looking ahead, Rodenburg acknowledges that the energy transition is taking shape, though the speed of fleet electrification remains uncertain. He emphasises that energy is becoming more expensive and must be used as efficiently as possible, with rolling resistance and air resistance representing losses to be minimised. An optimal tyre, he concludes, brings measurable benefits at every stage of the fleet’s transformation, an area where the rolling resistance optimised Conti Eco Gen 5 excels in contributing to fleet optimisation.
