Schwalbe has announced a new recycling program with the aim to hopefully create new tires using old ones.
After spending decades researching, Schwalbe has revealed that it has now had a big breakthrough in tire recycling. Working together with the Technical University of Cologne and recycling specialists Pyrum Innovations, Schwalbe says it now has a "holistic recycling process" to recycle used tires from all brands without waste.
Schwalbe says that until now bike tires were incinerated causing plenty of damage to the environment, but it says the new process will help close the loop. The new technique was created in a garden shed by Pascal Klein who went on to found Pyrum Innovations where it runs the only tire-pyrolysis plant in the world that operates year-round.
Pyrum Innovations has created a two-step process for the recycling with the tires fire being shredded to create rubber granules, textile fiber and steel. Next the rubber granules are taking to a pyrolysis oven where they are heated at 700°C without oxygen. This step creates a gas that is used to power the pyrolysis plant making it fully self-sufficient. The pyrolysis coke is then worked on to create recycled carbon black (rCB) for future tires. The remaining oil can be used to create textile fibers.
