Towards dandelion days

By Sharad Matade

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 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 on production-side is its industrialisation on bicycle tyres

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.

Enviro Disputes Infiniteria’s Request To Terminate Company Reorganisation

Enviro Disputes Infiniteria’s Request To Terminate Company Reorganisation

Scandinavian Enviro Systems AB (publ) has disputed a request from Infiniteria Sweden AB and Infiniteria Europe Sàrl to terminate the company’s ongoing reorganisation. In a statement submitted to the Gothenburg District Court on 22 April, Enviro argued no grounds exist to end the process, originally approved on 27 February 2026. A creditors’ meeting on 18 March saw no opposition to the reorganisation continuing.

The dispute stems from Enviro’s decision to terminate the joint venture agreements with Infiniteria under Swedish law, calling them burdensome and loss‑making. Infiniteria filed a termination request on 15 April, which Enviro answered on 22 April. Enviro disputes the request and several supporting claims.

Enviro states the joint venture caused its financial difficulties, while its business plan shows opportunities to build a profitable enterprise using its patented technology. Infiniteria has asserted a preliminary damages claim of approximately EUR 84 million, but Enviro notes the claim is unsubstantiated and partially overlaps with ongoing arbitration announced on 6 February.

Enviro points to contractual liability caps, including EUR 3 million in the marketing and agency agreement and EUR 2 million in the license agreement. Infiniteria has not shown why these caps should not apply. Regarding the license agreement under English law, Enviro maintains termination was lawful, meaning Infiniteria’s exclusive right to Enviro’s technology has ceased.

Despite the legal conflict, Enviro reports strong global interest. A North American feasibility study is progressing faster than expected, and licensing dialogues are ongoing with around 10 stakeholders. Enviro remains determined to build long‑term value without the former joint venture’s constraints.

Nexen Tire America Outlines Early-Stage Collaboration As New Standard For OE Tyres

Nexen Tire America Outlines Early-Stage Collaboration As New Standard For OE Tyres

Nexen Tire America has detailed how original equipment tyre development has shifted from a standalone process to an integrated engineering effort conducted alongside new vehicle design. The company explains that modern vehicle complexity, driven by electrification and advanced driver systems, requires tyre engineering to begin in parallel with suspension, chassis and electronic control development. This earlier collaboration allows tyre performance to be optimised for hybrid and electric vehicle demands such as noise reduction, load capacity and rolling resistance.

Aaron Neumann, Head of the Nexen Tire America Technical Center, describes how suppliers must now adopt faster development cycles and deeper technical collaboration. The traditional model of selecting off-the-shelf tyres has been replaced by purpose-built designs tuned to specific safety, handling and efficiency targets. Electric vehicles have added further criteria including range optimisation and tyre noise mitigation.

To manage these demands, Nexen has expanded its use of simulation and modelling technologies. Finite element analysis and data-driven tyre modelling allow engineers to evaluate performance early in the development cycle, reducing the number of physical prototypes required. Despite this digital focus, physical testing remains extensive and includes laboratory procedures such as high-speed endurance, rolling resistance, uniformity, noise and flat-spotting assessments.

On-road validation involves instrumented traction and braking tests, ride and handling evaluations, treadwear analysis and durability testing across varied surfaces and climates. Each tyre’s tread pattern, construction, footprint and profile are refined through iterative testing specific to the target vehicle. While some materials overlap with replacement tyres, original equipment fitments are engineered to balance performance, efficiency and comfort.

Over the past decade, Nexen Tire has more than doubled its original equipment portfolio in North America. This growth is attributed to an engineer-to-engineer collaboration model emphasising transparency and responsiveness. Many technologies developed for original equipment programmes, including advanced compounds and tread designs, are later incorporated into replacement tyres.

For consumers, these behind-the-scenes engineering efforts result in tyres more precisely matched to vehicle performance. Neumann notes that modern tyres rank among the most complex vehicle components, having to deliver safety, efficiency and comfort simultaneously across a wide range of conditions, even if that complexity remains largely invisible to drivers.
