Continental builds concept tyre from around 43% recycled materials

Continental has built a concept tyre with around 43 percent recycled content under an EU-funded research effort called Project ZEVRA - a marker of how far tyre-makers can push circularity when the chemistry allows it. For fleets watching sustainability reporting creep into procurement scorecards, it's a useful proof point rather than a product on the shelf just yet. (Continental)

The figure matters because tyres are one of the few consumables where recycled-material content is both measurable and increasingly asked about by corporate sustainability teams. Beyond saying the concept achieves the highest EU label rating for rolling resistance, Continental hasn't published durability or braking data, so there's no basis yet for judging whether wear rates or stopping distances hold up at this level of substitution. It's a research concept, not a homologated product, so treat the number as a ceiling being tested rather than a spec you can order. (Continental)

Why this matters: tyre sustainability credentials are heading the same way BIK and CO2 reporting did a decade ago - from nice-to-have to procurement requirement. Fleets setting multi-year tyre contracts should start asking suppliers what recycled-content roadmap sits behind current ranges, before it becomes a compliance question rather than a preference.
