Expanding the global shift to recycled materials in tyres 

Continental has been a leader in incorporating sustainable practices in the tyre industry, and ContiRe.Tex technology is a testament to this commitment. Launched in 2021, ContiRe.Tex has revolutionised the use of recycled materials in tyre production by replacing conventional polyester with high-performance yarn made from recycled PET bottles. This groundbreaking technology will now be expanded to global markets in line with Continental's vision for a sustainable future.

Key features of ContiRe.Tex technology

Driven by a commitment to sustainability, Continental's ContiRe.Tex technology uses polyester yarn made from recycled PET bottles to completely replace conventional polyester in tyre casings. This innovation not only improves the sustainability of the tyres but also ensures that the performance and safety standards are met without compromise. The technology was initially introduced in selected tire models, including the PremiumContact 6, EcoContact 6, AllSeasonContact and our more sustainable tyre, the UltraContact NXT.

Achievements and mass production 

Environmental impact: By using recycled PET bottles, Continental significantly reduces the carbon footprint of its tire production. Each set of standard passenger car tyres made with ContiRe.Tex technology uses the material from around 40 recycled PET bottles (9 to 15 per tyre).

Quality and performance: Laboratory and tyre tests conducted by Continental have shown that fibers made from recycled PET perform as well as conventional polyester fibers made from crude oil. They have the same quality, stability, and suitability for tyre production due to their tensile strength, toughness and thermal stability. 

Starting in mid-2024, Continental will begin mass production of tyres incorporating ContiRe.Tex technology in its plants in Korbach and Sarreguemines. By 2025, this technology will be implemented in all Continental tyre plants globally, marking a significant milestone in Continental’s sustainability journey. This strategic expansion is part of Continental’s broader objective to increase the share of sustainable materials in its products. 

Production process

Mass Balance Approach (MBA)

To facilitate the integration of new sustainable materials such as ContiRe.Tex, Continental uses the Mass Balance Approach (MBA). The MBA is a proven method in the automotive industry to manage the complexity of material integration while ensuring continuous supply. It allows Continental to introduce new materials in batches while ensuring that existing materials remain available as a backup. This approach not only limits complexity but also accelerates the ramp-up of sustainable materials, making it possible to meet the company's ambitious sustainability goals.

Key benefits of MBA

Simplified complexity: MBA limits the complexity involved in handling numerous combinations of materials and customer requirements.

Accelerated ramp-up: This approach faster adoption of sustainable materials.

Continuous supply: Ensures that current materials can be used as a backup, maintaining a stable supply chain as new materials are introduced in batches.

Our sustainability commitment guides our efforts

  • Continental consumes 55% less water and 17% less energy than the industry average of per metric ton of tyres produced
  • We plan to further reduce this by another 20% by 2030
  • Since the end of 2020, grid electricity purchased for our tyre production sites worldwide is carbon-neutral thanks to the procurement of energy attribute certificates
  • Continental is a member of the RE 100 initiative that fosters renewable energy
  • Tyre production by Continental will be carbon neutral by 2040
  • We aim to be completely climate-neutral along our entire value chain by 2050
