World’s first bicycle tyre made from used tyres: Pyrum supplies rcB for Schwalbe’s “Green Marathon”

  • First product from the Schwalbe Recycling System developed by Pyrum, Ralf Bohle GmbH and TH Köln on the market
  • Pyrum supplies recycled carbon black (rcB) for the production of the innovative bicycle tyre and thus makes a significant contribution to saving more than a third of CO2eQ compared to the predecessor model
  • “Green Marathon” receives Eurobike Award and is the only product to receive the Green Award at the Eurobike trade fair in Frankfurt

Dillingen /​Saar, 26 June 2023 – Pyrum Innovations AG (“Pyrum”, the “Company”, ISIN: DE000A2G8ZX8), a pioneering company that sustainably recycles used tyres with its globally patented, unique pyrolysis technology, and bicycle tyre manufacturer Ralf Bohle GmbH (brand: “Schwalbe”) have developed the world’s first bicycle tyre made from recycled tyres. The “Green Marathon” 100 % is manufactured using recycled carbon black (rCB) from Pyrum, which is a direct product of the recycling process and replaces fossil carbon black.

The production of the innovative bicycle tyre saves more than a third of CO2eQ compared to the predecessor model. To determine the CO2 savings, a detailed product carbon footprint (PCF) was calculated for both models and analysed in accordance with the current IPCC AR6 standard (GWP 100, excl. biogenic CO2).

Pascal Klein, CEO of Pyrum Innovations AG: “The Green Marathon is an impressive example of how Pyrum and its partners can close the material loop. We are proud that our recycled material forms the basis for the world’s first bicycle tyre made from used tyres. This development is further proof of our commitment to sustainability and the circular economy. Together with Schwalbe, we will continue to work on creating environmentally friendly solutions for the tyre industry and continuously expand recycling opportunities.”

A new benchmark in terms of environmental friendliness: the “Green Marathon” is the first product to emerge from the Schwalbe Recycling System. This is a joint project between Pyrum, Ralf Bohle GmbH and the Cologne University of Applied Sciences, which enables the world’s first and to date only holistic process for recycling used bicycle tyres. In total, the “Green Marathon” consists of 70 % recycled and renewable materials, uses only fairly traded natural rubber and thus closes the material cycle. For this product innovation, the “Green Marathon” received the Eurobike Award at the Eurobike trade fair in Frankfurt and – as the only product – also the Green Award, which is presented for remarkable product innovations in the field of sustainability.

About Pyrum Innovations AG

With its patented pyrolysis technology, Pyrum Innovations AG is active in the attractive recycling market for used tyres and various plastics. Pyrum’s pyrolysis process is largely energy self-​sufficient and, according to the Fraunhofer Institute, saves significantly more CO2 emissions than today’s standard recycling processes for used tyres – especially compared to incineration in cement plants – and produces new raw materials such as pyrolysis oil, gas and recycled carbon black (rCB) from the waste used as input materials. In this way, Pyrum closes the material cycle and pursues a 100% sustainable business model. As a pioneer, Pyrum Innovations AG was the first company in the waste tyre recycling sector to receive REACH registration from the European Chemicals Agency (ECHA) for the pyrolysis oil it produces back in 2018. This means that the oil is recognised as an official raw material that can be used in production processes. In addition, Pyrum has received ISCC PLUS certification for the pyrolysis oil and the rCB. Both products are therefore recognised as sustainable and renewable raw materials. Pyrum has also received ISO 14001 certification for its environmental management system and ISO 9001 certification for its quality management system. These successes have also been recognised by international experts in the tyre industry. For example, Pyrum was honoured at the first Recircle Awards in the category Best Tyre Recycling Innovation and has been a finalist for the German SME award three times in a row.
