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.
