Analysis by Fraunhofer Institute confirms enormous CO2 reductions for Pyrum’s pyrolysis process compared to conventional recycling processes for end-of-life tyres

  • Fraunhofer Institute confirms for the first time that Pyrum's pyrolysis process is the first chemical recycling process to save more CO2 than the material recycling of end-of-life tyres
  • Compared to the current recycling mix in Germany, even up to 72% more CO2 is saved
  • This scientifically proves that Pyrum not only closes the material cycle, but also saves more CO2 than all currently used, common recycling processes for end-of-life tyres

Dillingen / Saar, 15 September 2022 – Pyrum Innovations AG ("Pyrum"), a pioneer in the sustainable recycling of end-of-life tyres (ELT) based on its patented pyrolysis technology, has for the first time obtained a determination of the CO2 savings of its pyrolysis process as part of a "Life Cycle Assessment" (LCA, eco balance) by the Fraunhofer Institute for Environmental, Safety and Energy Technology. The results once again demonstrate the unique and sustainable efficiency of the Pyrum technology. Compared to the use of fossil raw materials, Pyrum’s process saves 747 kg CO2 equivalent per tonne of ELT; if the use of the waste heat produced is included, as Pyrum is already applying, even 965 kg CO2 equivalent are saved per tonne of ELT.

By comparison, the current recycling mix in Germany achieves savings of 561 kg CO2 eq. per tonne of used tyres. In comparison, Pyrum performs up to 72% better.

Pascal Klein, CEO of Pyrum Innovations AG: "The enormous CO2 savings of our method surprised even us to this extent. The results of the Life Cycle Assessment show us once again that our pyrolysis technology is the leading method for recycling end-of-life tyres. While other methods are severely limited in market potential, we are only at the beginning with pyrolysis and see major growth opportunities in this area."

The current recycling mix for ELT in Germany is made up of material recycling (market share 52%) and the incineration of used tyres in cement plants (42%) and refuse derived fuel (RDF) power plants (6%).

The infill method, the recycling of used tyres for the production of, for example, playground flooring or sports fields from rubber granulate, also achieves large CO2 savings of 778 kg CO2 eq. per tonne of ELT. However, the Pyrum’s pyrolysis process including the use of waste heat exceeds the savings by 187 kg CO2 -eq. per ton of used tyres. In addition, the results of the Fraunhofer Institute confirm that the market potential of the infill method is clearly limited - at the moment it comes to a maximum market share of 52%, which can hardly be expanded any further. In addition, pyrolysis can also keep the materials in the loop over several life cycles.

RDF power plants, which currently dispose of 6% of ELT in Germany, produce as much as 164 kg more CO2 eq. per tonne of used tyres than power plants using fossil fuels. When used tyres are incinerated in cement plants, the CO2 saving is 395 kg CO2 eq. per tonne of ELT.


About Pyrum Innovations AG
Pyrum Innovations AG is active in the attractive recycling market for end-of-life-tyres with its patented pyrolysis technology. Pyrum's pyrolysis process is completely energy self-sufficient, saves up to 98% of the CO2 emissions normally generated during the disposal of end-of-lifetyres in a cement plant and produces new raw materials such as pyrolysis oil, gas and recovered carbon black from the waste used as input materials. In this way, Pyrum closes the recyclable material loop and pursues a completely sustainable business model. As a pioneer, Pyrum Innovations AG was the first company in the end-of-life-tyre recycling sector to receive REACH registration from the European Chemicals Agency (ECHA) for the pyrolysis oil it produces. This means that the oil is recognised as an official raw material and can be used as a raw material in production processes. In addition, Pyrum is continuously researching both new input materials as well as new raw materials to be produced, for example with the ongoing tests for the extraction of hydrogen from the gas obtained by means of the patented technology. These achievements have also been recognised by international experts in the tyre industry. For example, Pyrum won the Best Tyre Recycling Innovation category at the inaugural Recircle Awards and has been nominated for the “Grand Prix Mittelstand” ("Großer
Preis des Mittelstandes") from the German state of Saarland.
