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 has unveiled a concept tyre developed under the EU-funded ZEvRA project, which is composed of approximately 43 percent recycled materials. The innovation serves as a demonstration of the potential inherent in advanced material approaches while simultaneously underscoring the critical need for a dependable regulatory framework to facilitate the industrial-scale adoption of recycling technologies.

The technical achievement is set against the backdrop of the ZEvRA initiative, an acronym for ‘Zero Emission Electric Vehicles Enabled by Harmonized Circularity’. This two-year EU project, slated to conclude in 2026, is dedicated to enhancing the circular economy for electric vehicles across the entire value chain. As the sole tyre manufacturer participating in the consortium, Continental brings specialised expertise to the collaborative effort.

Addressing the complexities of tyre production, which requires a precise balance of numerous high-performance raw materials to guarantee safety, efficiency and durability, the concept tyre represents a significant milestone. The successful integration of a substantial proportion of recycled content into a safety-critical component, without compromising performance standards, highlights the compatibility of ecological responsibility and product excellence. The tyre has achieved the highest possible rating on the EU rolling resistance label.

The ZEvRA concept tyre incorporates a variety of recycled materials, including tall oil, steel, rubber derived from end-of-life tyres and polyester fibres sourced from recycled PET bottles. Continental employs advanced methodologies such as pyrolysis to extract recovered carbon black from old tyres for repurposing. Since 2023, this material has been utilised in all newly manufactured solid rubber tyres at the Korbach facility. Additionally, the company uses sand residue from foundries in a recycling process to produce an alternative silica variant, effectively keeping materials in circulation and reducing the demand for primary resources.

Continental executives have articulated the strategic importance of this development. Dr Andreas Topp, head of Platform Development and Industrialization for passenger-car tyres, emphasises that while circular materials are key to sustainable mobility, the full impact of technological progress requires reliable and aligned policy frameworks. Jorge Almeida, head of Sustainability for Continental’s Tires group sector, stresses the necessity of establishing innovative recycling technologies on an industrial scale and creating closed material flows. He advocates for a standardised, transparent approach to calculation and reporting, developed through close dialogue between policymakers and stakeholders.

Beyond the recycled content, the concept tyre also features approximately 13 percent renewable raw materials and 25 percent mass-balance-certified materials, bringing the total share of sustainable sources to over 80 percent. Continental is progressively increasing the use of such materials across its portfolio, with the share of purchased renewable and recycled production materials reaching 28 percent in 2025, with a target of at least 40 percent by 2030. Insights from the ZEvRA project will guide the company’s future development of materials and technologies, focusing on industrial availability and scaling manufacturing processes.
