Continental has announced a strategic push to increase its use of recycled and renewable materials in tyres from 26% to at least 40% within five years, leveraging innovative technologies and sustainable sourcing to revolutionise industry standards.
Continental is advancing its commitment to sustainability by significantly expanding its use of renewable and recycled materials in tyre production, aligning with the principles of a circular economy. In 2024, these materials accounted for an average of 26% of the company’s tyre portfolio, and Continental has set an ambitious target to increase this proportion to at least 40% within the next five years. This strategic focus encompasses not only the rubber compounds but also the critical reinforcement materials that ensure tyre stability, safety, and performance.
A key aspect of Continental’s sustainability drive is the increased incorporation of recycled steel and polyester yarn made from recycled polyethylene terephthalate (PET) bottles. Reinforcement materials like steel and textiles constitute a significant share of the tyre composition, approximately 18% in passenger car tyres and even higher in commercial and specialty vehicle tyres. Steel, for instance, is essential in multiple tyre components, including the casing reinforcement, bead core, and tread layers, where it provides durability, load capacity, puncture resistance, noise reduction, fuel efficiency, and extended range for both combustion and electric vehicles. Continental is leveraging recycled steel in its production without compromising on these vital performance criteria.
Similarly, the company has innovated in textile reinforcement through ContiRe.Tex technology, developed in collaboration with textile manufacturer OTIZ. This technology converts recycled PET bottles, often sourced from regions lacking closed-loop bottle recycling systems, into high-performance polyester yarns used in tyre casings, which stabilize the rubber bead structure. Depending on the tyre size, up to 15 recycled PET bottles may be used per tyre. Verified by SGS, this process reduces CO₂ emissions by approximately 28% compared to fossil-fuel-based polyester cord fabric. Continental first introduced this polyester yarn in standard passenger car tyres such as the UltraContact NXT, demonstrating both sustainability and efficacy in tyre performance.
Beyond materials substitution, Continental is also innovating in sustainable manufacturing processes. In collaboration with global textile reinforcement leader Kordsa, the company co-developed COKOON, an environmentally friendly bonding technology that bonds textile reinforcements to rubber compounds without using hazardous chemicals like resorcinol or formaldehyde. This technology not only enhances environmental credentials but also maintains the high-quality standards required in tyre production. Importantly, Continental and Kordsa have made COKOON available as an open-source, royalty-free solution, encouraging broader industry adoption toward sustainability goals.
In addition to steel and polyester reinforcements, Continental is exploring alternative raw materials across all material groups, including synthetic rubber derived from used cooking oil, bio-based resins, and silica sourced from rice husk ash. These substitutions support the company’s ambition to accelerate sustainable mobility without sacrificing safety or performance. Continental employs a mass balance approach to manage the integration of renewable and recycled materials in its supply chain, providing transparency and traceability.
These efforts exemplify Continental’s broader sustainability strategy, which includes the commercialisation of concept tyres like the Conti GreenConcept, featuring recycled steel, recovered carbon black, recycled polyester, and natural silica, underscoring the company’s commitment to green innovation. Continental’s approach not only reflects an evolving product portfolio but also aims to influence the wider tyre manufacturing industry by fostering supplier innovation and offering sustainable technologies such as COKOON to competitors.
Matthias Haufe, Director of Materials Development and Industrialisation at Continental Tires, summarised this vision: “We are not reinventing the wheel, but the tyre, with more sustainable materials and more environmentally friendly production processes. It’s not just about the rubber itself. We also focus on the materials that shape the rubber and make tyres stable and safe. Our goal is to use at least 40% renewable and recycled materials in our tyres within five years. Every alternative material brings us a significant step closer to this goal.”
As industrial decarbonisation intensifies within the automotive and transportation sectors, Continental’s proactive incorporation of renewable and recycled raw materials, coupled with greener manufacturing technologies, positions it as a leading player in evolving towards a more sustainable tyre industry. The company’s transparent targets and open collaboration with suppliers and competitors further demonstrate its commitment not only to reducing environmental impact but also to setting new industry standards for circularity and sustainability in tyre production.
