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.

Liberty Tire Recycling Releases First US Company-Commissioned LCA On Rubber-Modified Asphalt

Liberty Tire Recycling Releases First US Company-Commissioned LCA On Rubber-Modified Asphalt

Liberty Tire Recycling has published the industry’s first US company-commissioned lifecycle assessment (LCA) centred on rubber-modified asphalt solutions made from recycled tyres. The study was commissioned by Liberty and carried out by Boundless, applying internationally recognised LCA methodology to evaluate the environmental impacts of the company’s asphalt-related products against conventional alternatives used in asphalt modification.

The company described the assessment as a notable step forward for rubber-modified asphalt. Environmental gains are routinely linked to recycled tyre materials in road building, yet Liberty said this analysis supplies quantified evidence behind such assertions. Greenhouse gas emissions tied to its rubber-modified asphalt solutions were tracked throughout their lifecycle.

Results showed that Liberty's asphalt products carried substantially lower greenhouse gas impacts than conventional SBS polymer modifiers. Recovering and reusing end-of-life tyre materials was also found to deliver environmental benefits exceeding the impacts of processing them. Liberty said the findings give transportation agencies, engineers, contractors and infrastructure stakeholders data-driven insights for choosing materials.

Four products were assessed: crumb rubber and three asphalt additives, namely dry mix rubber additives, a DOT additive and combined micronised rubber powder with the Rheopave additive. Dry mix rubber additives yielded the largest carbon benefit, avoiding up to 0.577 kg CO₂e per pound produced, while the tyre-derived products achieved over 100 percent lower greenhouse gas footprint than traditional SBS modifiers. Each product assessed generated a net environmental benefit, with reductions spanning 0.47 to 0.57 kg of CO₂e per pound.

Liberty said the study helps set a benchmark for measuring and communicating environmental impacts as sustainability gains prominence in infrastructure projects, and that transparent, science-based data will matter increasingly to public agencies and industry leaders weighing performance and environmental goals.

Vredestein Quatrac Pro 2 Sets New Benchmarks In Independent All-Season Tyre Tests

Vredestein Quatrac Pro 2 Sets New Benchmarks In Independent All-Season Tyre Tests

The all-new Vredestein Quatrac Pro 2 premium ultra-high-performance all-season tyre has had its class-leading capabilities confirmed through independent testing in Spain and Finland. The tyre established new benchmarks for wet braking and recorded the fastest snow handling lap times against four leading all-season rivals.

Testing in Finland at the UTAC winter facility used a sensor-equipped BMW 5 Series to measure speed and lap times, with all tyres subjected to identical procedures. The Quatrac Pro 2 achieved the quickest snow handling lap, showing exceptional grip, balance and controllability, which testers praised for excellent response and stability in all circumstances. Its snow performance is aided by 3D interlocking sipes at the shoulder, whose zig-zagged inner faces in horizontal and vertical planes limit tread block movement.

In Spain, Applus+ IDIADA assessed dry and wet handling and braking on certified asphalt with defined water depth. The tyre outperformed key competitors in wet conditions, delivering a 7 percent wet-braking advantage over one long-established segment rival, and separate testing confirmed an A wet-grip rating across the entire size range, unique in the UHP all-season segment. Four longitudinal grooves in every size, also unique in the category, plus directional lateral grooves, support water evacuation and aquaplaning resistance.

Compared with its predecessor, abrasion resistance has improved by 8 percent to maximise tyre life, while rolling resistance is reduced by 10 percent to boost driving range, underlining suitability for electric vehicles. The Quatrac Pro 2 is available now for wheel diameters from 17 to 24 inches, with section widths up to 355 mm for powerful passenger vehicles.

Daniele Lorenzetti, Chief Technology Officer, Apollo Tyres Ltd, said, “Vredestein has long been recognised for its premium all-season tyres, and these independent tests reinforce that reputation. The Quatrac Pro 2 delivered exceptional grip and traction against other premium competitors while also improving efficiency and longevity compared with its predecessor.”
