Closed production cycle for bicycle tyres

Pyrum supplies recycled carbon black (rCB) to Schwalbe for the production of new bicycle tyres

  • Series deli­very of carbon black (reco­vered Carbon Black, rCB) by Pyrum to Schwalbe has begun
  • The cycle of bicycle tyre produc­tion is thus comple­tely closed thanks to the already initiated “Schwalbe Recy­cling System”
  • Sustain­ably produced bicycle tyres to be laun­ched on the market in June 2023

Dillingen /​Saar, 28 November 2022 — Pyrum Inno­va­tions AG (“Pyrum”), a pionee­ring company that sustain­ably recy­cles used tyres with its globally patented, unique pyro­lysis tech­no­logy, announces the first deli­very of recy­cled carbon black (rCB) to Ralf Bohle GmbH with its Schwalbe brand. The rCB comes from old bicycle tyres that Schwalbe coll­ects from specia­list dealers throug­hout Germany with its “Schwalbe Recy­cling System”. Pyrum then takes over the mecha­nical proces­sing and pyro­lytic recy­cling of the old tyres at its pyro­lysis plant in Dillingen. Schwalbe is now starting produc­tion of the first bicycle tyre to be made enti­rely from rCB. The tyre will be presented in June 2023 at the world’s largest bicycle trade fair Euro­bike in Frank­furt and will subse­quently be available in stores.

Pascal Klein, CEO of Pyrum Inno­va­tions AG: “One of our declared goals is to achieve a circular economy concept for the recy­cling of used tyres in the medium to long term. Toge­ther with our partner, Ralf Bohle GmbH and its Schwalbe brand, we have now come a big step closer to achie­ving this goal for bicycle tyres.”

The rCB was deli­vered to Schwalbe as part of the commis­sio­ning of the pelle­ti­sing system at the main plant in Dillingen. The pelle­tiser increases the trans­por­ta­bi­lity of the rCB and thus faci­li­tates the further proces­sing of the raw mate­rial. As a result, the rCB deli­very volume can be signi­fi­cantly increased. In addi­tion, produc­tion lines 2 and 3 at the site are expected to go into opera­tion in the first half of 2023 and signi­fi­cantly increase the proces­sing capa­city of used tyres — inclu­ding used bicycle tyres. The offi­cial opera­ting licence for the expan­sion has already been granted.

Back in July 2022, Pyrum and Ralf Bohle GmbH had already presented the Euro­bikeThe “Schwalbe Recy­cling System” for used bicycle tyres was unveiled at the 8th trade fair. The system enables the complete recy­cling of used tyres from all brands. To this end, Schwalbe has estab­lished a coll­ec­tion network so that used bicycle tyres can be handed in to all parti­ci­pa­ting specia­list dealers, which Schwalbe then coll­ects and deli­vers to Pyrum.

Frank Bohle, Mana­ging Director of Ralf Bohle GmbH: “The response to our Schwalbe Recy­cling System has been over­whel­ming. After starting with around 50 parti­ci­pa­ting specia­list dealers at the begin­ning of the year, we now have over 1,200 parti­ci­pa­ting dealers across Germany. We are now starting produc­tion of the first bicycle tyre that uses Pyrum’s rCB. Our medium-term goal is to produce all Schwalbe tyres from recy­cled carbon black and we want to continue to lead the way as pioneers with our inno­va­tive recy­cling solutions.”

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.
