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.

Pirelli has chosen the softest trio in its range for the Mexico City Grand Prix, with the C3 as Hard, the C4 as Medium and the C5 as Soft. This departs from last year, when a compound step using the C2 as Hard proved less appealing than the softer alternatives. The second round of the Americas triple-header takes place at the circuit named after brothers Pedro and Ricardo Rodríguez, unique on the calendar due to its altitude of over 2,000 metres.

A large portion of the circuit has been resurfaced, covering Turn 16 to Turn 1 and Turn 7 to Turn 16, leaving only the first sector largely unchanged. New asphalt normally brings higher grip and lower roughness, though its actual characteristics will need assessment during the opening stages. The track is often dirty early on, with grip improving lap after lap, and that evolution could be more pronounced this year.

The Autódromo Hermanos Rodríguez has traditionally been one of the least demanding circuits on tyres, with low-speed corners and limited lateral loads keeping wear under control. The thin air reduces aerodynamic load, increasing tyre slip and making graining a factor to watch, possibly more so with the smoother asphalt. The circuit's low severity could favour a one-stop race, though tyre management to extend stints will remain important, particularly for the rear axle.

Strategy may depend more on driver confidence in a compound than on genuine tyre life limitation, with some teams favouring softer compounds for grip and others the Hard for consistency. The Soft could play a central role, having shown strong characteristics on low-severity circuits. Braking performance also warrants monitoring, as the altitude reduces aerodynamic efficiency and the long main straight into Turn 1 could increase lock-up risk. Last year's grid was split between one-stop and two-stop strategies. This will be the sixth Grand Prix under the Mexico City Grand Prix name, with Max Verstappen the most successful driver at the venue with five victories, matching Red Bull. The Pirelli Podium Cap celebrates Día de los Muertos, which falls on race Sunday.

The U.S. Tire Manufacturers Association (USTMA) has published its 2025 End-of-Life Tire Market Report, continuing a biennial series begun in the early 1990s. With over 30 years of figures on tyre generation, destination markets and stockpiles, the study stands as the nation's most thorough accounting of what happens to tyres after they leave the road.

Of the 273 million tyres retired nationwide in 2025, some 79 percent were absorbed by end-use markets. Only lead-acid batteries surpass tyres as a recycled and reclaimed material; paper, aluminium, glass and PET plastic all trail behind. The result is that valuable rubber stays in productive circulation rather than accumulating in landfills.

Abandoned and illegal stockpiles shrank to roughly 42.1 million tyres, compared with about 48 million two years earlier – a 12 percent drop in that span and a 96 percent fall from the billion-tyre high of 1990. Colorado's cleanup effort accounted for much of the gain, eliminating over 12 million tyres, while New Jersey and Pennsylvania recorded large reductions. North Carolina, Tennessee and Delaware cleared their stockpiles entirely, and land disposal declined nearly 11 percent to 779 thousand tonnes.

Tyre-derived fuel stayed the biggest outlet, taking about 1,317 thousand tonnes, with ground rubber just behind at roughly 1,201 thousand tonnes. Cement kilns consumed about 5 percent more, reaching 821 thousand tonnes – 62 percent of all tyre-derived fuel – as carbon-reduction mandates and the fuel's biogenic nature enhance its appeal. Reclamation applications expanded by roughly a tenth.

Most declines arose from forces outside the industry's influence. Pulp and paper mill shutdowns halved nothing less than 40 percent of that outlet, while revised Michigan energy rules trimmed utility boiler demand by about 22 percent. Synthetic turf continues yielding ground to cork, coconut husk and olive pit infill; moulded and extruded goods eased from a 2021 high; and energy price swings have shifted tyre-derived fuel's competitiveness. Exports, however, climbed 270 percent since 2023 – from 253 thousand tonnes to 936 thousand tonnes – making them the third-largest outlet, driven by India's rapid growth and sustained fuel shipments to Japan and South Korea. USTMA urges exporters to confirm that receiving markets are environmentally sound and economically viable.

Near-term investments include Tire Recycling Foundation-backed environmental product declarations, wider chip seal use, advances in dry-process rubber-modified asphalt and pavement funding. Kentucky devoted over USD 1.16 million in 2025 to nine county rubber-asphalt projects, and California opened USD 6.57 million in grants for fiscal 2025–26. Pyrolysis is now quantifiable as it reaches commercial scale, and the Tire Recycling Foundation is growing into a platform for education, research and demonstration. State-level stockpile figures accompany the report on the ELT Report page of the association’s website.

Anne Forristall Luke, president and CEO, USTMA, said, “This report gives a picture of a market in transition. Stockpile cleanup continues, and 79 percent of end-of-life tyres reached end-use markets. At the same time, several domestic markets contracted, and the rise in exports shows strong demand for this material outside the US Together, those trends tell us our markets still depend on a handful of large industrial outlets, and that market development has to be the priority. The data points to where the work is needed, and much of that work is already underway.”

Amelia Chucholowski, Associate Director, Sustainability and Recycling Policy, USTMA, said, “International demand further demonstrates that this material has real value, but our priority is domestic circular end-use markets, because a tire processed here supports a US recycler, US jobs and US infrastructure. That includes ensuring that domestic processors have adequate feedstock. We’re watching it closely and working with our global partners both to understand what’s driving this trend and to report it transparently.

“The work that actually grows these markets is underway right now, and almost none of it shows up in a 2025 market report. Read this report as a snapshot of 2025. What we’re building now will be measured against in the future. State programmes have built one of the country’s great recycling success stories. 96 percent of the tyre stockpiles that existed in 1990 are gone, and the lesson is clear: when states fund their programmes, enforce the rules and invest in markets, results follow. The next chapter is about markets. The more states invest in uses like rubber-modified asphalt, the more tires become roads, products and energy here at home.”
