Pyrum Innovations AG („Pyrum“) 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 equivalent 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.“

Keeping Materials in Circulation Longer

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 equivalent per tonne of ELT. However, the Pyrum’s pyrolysis process including the use of waste heat exceeds the savings by 187 kg CO2 equivalent 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 equivalent 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 equivalent per tonne of ELT.
