Continental is making huge strides in using sustainable and recyclable raw materials.

Car tyres are round, black and made of rubber. Look closer, however, and you’ll see that the design of tyres and the interaction of the various materials that go into making them are extremely complex. But for some time now, material experts and tyre engineers at Continental have been bringing about a silent revolution. By 2050 at the latest, all tyres are to be made of sustainable materials. There is still a long way to go until then. But step by step, it is already becoming apparent which raw materials will find their way into tyre construction in the future. These include waste products from agriculture (such as the ash from rice husks), rubber from dandelions, recycled rubber or PET bottles.

Claus Petschick, Head of Sustainability at Continental Tires, is clear about Continental’s mission, saying, “Continental is on the road toward becoming the most progressive manufacturer in the tyre industry in terms of sustainability. We aim to use 100 percent sustainable materials in our tyre products by 2050 at the latest. Our innovative power enables us to break new and even more sustainable ground. This encompasses everything from the origin and sourcing of our materials through to the reuse and recycling of our tyres.”

Already today, around 15-20 percent renewable or recycled materials are used in a standard passenger car tyre from Continental. To further increase the proportion of sustainable materials and conserve valuable resources, Continental continuously analyses and reviews all raw materials used in tyre production.

Perfect material matching for maximum safety 
Depending on the application, season and environment, tyres have to fulfill specific requirements. This can be seen in, for example, the tread design. But in other areas – the composition of the rubber compound, for example – these changes are not so readily visible. Passenger car tyres from Continental consist of as many as a hundred different raw materials.

Their precise composition has a major impact on the tyres and their handling characteristics. The ability to deploy the various materials with their unique properties and interdependencies in specific ways is a complex balancing act for Continental’s engineers and material experts. Only when all the materials are ideally matched to each other can safe, energy-efficient and durable high-performance tyres be created.

Natural rubber still essential due to exceptional properties
Natural rubber is essential for ensuring outstanding tyre performance. This natural product accounts for between 10 and 40 percent of the entire weight of modern high-performance tyres. Its special properties include the high level of strength and durability, which are caused by the strain-induced crystallisation of the rubber. The tyre industry is the biggest consumer of global rubber production, accounting for more than 70 percent. However, Continental considers natural rubber a sustainable material only if it is sourced responsibly. Therefore, the company employs an integrated approach aimed at making the complex and fragmented supply chains for natural rubber more sustainable, including using cutting-edge digital technology, local involvement and close collaboration with capable partners with the goal of improving transparency and traceability along the entire value chain. Meanwhile, with its Taraxagum project, Continental is pursuing an innovative approach to ensure that it can become less dependent on natural rubber grown primarily in southeast Asia. The tyre manufacturer is working alongside partners on industrialising the extraction of natural rubber from specially cultivated dandelion plants.

Sustainable plant-based fillers 
In addition to rubber, fillers such as silica are essential to tyre assembly. Silica, for example, helps to optimise characteristics such as grip, rolling resistance and tyre life. In the future, rice husks will be used as the source material for sustainably-produced silica. Rice husks are a waste product of rice production and cannot be used as food or animal feed. Silica derived from the ash of rice husks is more energy-efficient when used in manufacturing than that obtained from conventional materials such as quartz sand.

Plant-based oils, such as rapeseed oil and resins based on residual materials from the paper and wood industries, already offer an alternative to crude-oil-based fillers in Continental's tyres. Only oils that meet technical quality standards and are not suitable for consumption are used. Oils and resins allow for flexibility in terms of tyre compounds and so improve the material’s grip.

Expanding the circular economy
Continental is aiming for fully circular operations in its tyre production by 2050 at the latest. In addition to the use of renewable materials, the company is working systematically on using recycled raw materials in tyre production. This is intended to ensure that carbon black – another crucial filler in rubber compounds – can be obtained on a large scale in the future. Continental recently signed a development agreement with Pyrum Innovations with a view to further optimising the recycling of materials from old tyres. To do this, Pyrum breaks the old tyres down into their constituent parts in an industrial furnace using a special pyrolysis process. This way, valuable raw materials contained in end-of-life tyres can be extracted and recycled. Both companies are working towards obtaining high-quality raw materials from the pyrolysis oil obtained for Continental's tyre production in the medium-term, in addition to the direct use of high-quality carbon black. In the long-term, the tyre manufacturer and Pyrum are aiming to establish a closed loop circular economy concept for the recycling of old tyres.

Recycled rubber from end-of-life tyres
In addition to pyrolysis, Continental is also making use of mechanical processing of end-of-life tyres. Rubber, steel and textile cord in particular are separated from one another in a highly sophisticated process. The rubber is then prepared for re-use as part of new rubber compounds.

Continental has a long history of working consistently to introduce end-of-life tyres into the circular economy to conserve resources and the environment. A material known as Conti-Reclaim has been obtained as part of the truck tyre retreading process at the company’s plant in Stöcken in Hanover since 2013. It has been used in tyre production at Continental for years. To expand the range of applications for the recycled rubber and optimise the properties for the various fields of application, Continental uses not only Conti-Reclaim but also recycled rubber from other suppliers.

Recycled plastic bottles in tyre casing 
“Recycled raw materials are going to play a big role in making tyres more sustainable. We use recycled materials whenever possible. Comparable quality and material properties to conventional raw materials are crucial for us,” says Petschick.

For example, Continental is working with partners to obtain high-quality polyester yarn for its tyres from recycled PET bottles. PET bottles often end up in incinerators or landfills otherwise. With its ContiRe.Tex technology, the tyre manufacturer has developed a more energy-efficient and eco-friendly alternative that allows it to reuse between nine and fifteen plastic bottles for each tyre, depending on the tyre size. The recycled PET has already replaced conventional polyester in the structures of some tyre casing. The PET bottles used are sourced exclusively from regions where there is no closed recycling loop.

Systematically moving toward greater sustainability
Continental is working to advance innovative technologies and sustainable products and services throughout its entire value chain, from sourcing sustainable materials to recycling end-of-life tyres. The company is aiming to achieve 100 percent carbon neutrality by 2050 at the latest.

The Association of Natural Rubber Producing Countries (ANRPC) has released its Monthly NR Statistical Report for February 2026, detailing a period of significant market activity influenced by geopolitical tensions, macroeconomic changes and shifting supply-demand dynamics within the global natural rubber sector.

As per the report, global natural rubber production for 2026 is forecast to reach 15.324 million tonnes, a 2.2 percent increase from the 14.996 million tonnes recorded in 2025. February output alone is projected at 994,000 tonnes, marking a 3.4 percent year-on-year rise due to favourable weather and higher rubber prices. Despite this overall growth, production trends vary among member nations. While Thailand is expected to remain the top producer, Indonesia and Vietnam face short-term constraints from structural and agronomic issues. Meanwhile, Malaysia is advancing efforts to restore abandoned plantations, with the Rubber Production Incentive activated in Sarawak and Sabah and the Malaysian Rubber Board targeting the rehabilitation of 4,137 hectares of idle land in 2026.

Physical and futures markets saw notable price increases across major grades in February. In Kuala Lumpur, SMR-20 averaged USD 2.01 per kilogramme, a 5.13 percent monthly gain, while STR-20 in Bangkok rose 5.12 percent to USD 2.11 per kilogramme. Sheet rubber grades also strengthened, with RSS-3 increasing 7.84 percent to USD 2.35 per kilogramme and RSS-4 in Kottayam surging 10.38 percent to USD 2.34 per kilogramme. Centrifuged latex in Kuala Lumpur closed the month at USD 1.61 per kilogramme. Futures mirrored this firming trend, as the Shanghai Futures Exchange May 2026 contract averaged roughly 16,508 CNY (approximately USD 2,388) per tonne and the SGX contract averaged USD 1.92 per kilogramme, supported by strong demand and tightening supply expectations ahead of the seasonal low-yield period from February to May.

Crude oil volatility added further complexity, with Brent averaging USD 70.89 per barrel in February – up 6.43 percent from January – before spiking to approximately USD 104 per barrel in early March following military actions in the Middle East and the closure of the Strait of Hormuz, a conduit for nearly 20 percent of global oil supply. This has introduced a risk premium with implications for synthetic rubber competitiveness and natural rubber demand. Currency shifts also play a role, as the Malaysian Ringgit appreciated modestly to 3.89 MYR per USD and the Thai Baht strengthened to around 31.08 THB per USD by late February, affecting trade competitiveness. Looking ahead, rising automotive production, especially of new energy vehicles in China, India and Southeast Asia, is expected to sustain demand and support prices. However, risks persist from US-China trade tensions, Middle East geopolitical instability, weather uncertainties during the low-yield season and currency fluctuations tied to US monetary policy, all of which could disrupt supply chains and export revenues.
