Pyrum and Schwalbe developed the world's first bicycle tire made from recycled tires
Pyrum Innovations AG (Pyrum), a pioneering company that recycles end-of-life tires sustainably with its globally patented, unique pyrolysis technology, and the bicycle tire manufacturer Ralf Bohle GmbH (Schwalbe brand) have developed the world's first bicycle tire made from recycled tires. Pyrum's Green Marathon uses 100% recycled carbon black (rCB), which is a direct product of the recycling process and replaces fossil carbon black. The production of the innovative bicycle tire saves more than a third of CO2eQ compared to the previous model. To determine the CO2 savings, a detailed Product Carbon Footprint (PCF) of both models was calculated and evaluated according to the current IPCC AR6 standard (GWP 100, excl. biogenic CO2).
