Continental is accelerating its commitment to sustainability by integrating a growing proportion of renewable and recycled materials into its tyre manufacturing. The company’s current average of 26 percent is projected to rise by several percentage points within the year, with a strategic goal of reaching at least 40 percent by 2030. A central pillar of this initiative involves rethinking the sourcing of two essential components: rubber and resins.

Rubber is a fundamental material, constituting up to 40 percent of a modern high-performance tyre’s weight. Continental utilises a complex blend of up to 100 different raw materials, engineered into numerous customised rubber compounds for each tyre. The portfolio includes both natural rubber, prized for its durability and resistance in critical areas like truck treads, and synthetic rubber, which enhances braking performance and rolling resistance in passenger vehicles. The company is now progressively replacing conventional fossil-based synthetic rubber with more sustainable alternatives. This includes synthetic rubber derived from used cooking oil and pyrolysis oil from end-of-life tyres, sourced from certified partners like Synthos and TotalEnergies Cray Valley.

Complementing rubber, specialised resins are vital for optimising a tyre’s performance characteristics. These resins help fine-tune the balance between elasticity and resilience, which directly improves wet grip, abrasion resistance and energy efficiency. Continental is incorporating circular resins, also certified under the ISCC PLUS standard, which originate from renewable feedstocks like vegetable oil or used cooking oil.

Furthermore, the company is adopting sustainable alternatives for key additives. For instance, it is the first tyre manufacturer to use a certified biocircular version of the antioxidant TMQ. Produced from waste materials such as recycled cooking oil, this additive achieves a carbon footprint over 30 percent lower than its conventional counterpart.

To systematically track and scale the use of these sustainable materials, Continental employs a mass balance approach. This method allows fossil-based, renewable and recycled feedstocks to be mixed in production while accurately attributing the sustainable content to the final product. This system provides verifiable documentation and enables Continental to continuously increase its use of certified materials across its entire tyre range.

Jorge Almeida, Head of Sustainability at Continental Tires, said, “We’re closing the loop: Continental is ramping up its commitment to a circular economy and mapping out its path for the future. Innovative solutions enable us to use more sustainable raw materials, such as synthetic rubber made from used cooking oil or resins based on certified renewable feedstocks originally derived from vegetable oil.”

Matthias Haufe, Head of Material Development and Industrialisation at Continental Tires, said, “The mass balance approach enables us to efficiently manage the complexity of the raw materials portfolio and track how these raw materials are used at multiple production sites in a wide range of markets. In this way, we can steadily increase the share of renewable and recycled materials in our tyre production – and transparently document the progress we make.”
