Abstract
End-of-life tyres (ELTs) are difficult to recycle due to their complex composition. Although there are several possible pathways to manage ELTs, in Germany roughly 50 % of the ELTs are still incinerated. One emerging technology that promises recycling of ELTs is the thermochemical processing through pyrolysis. This technology enables to recover carbon black and pyrolysis oil that can be reused for new tyres. Therefore, this study presents a comprehensive life cycle assessment to compare the environmental impacts from pyrolysis of ELTs against current dominant alternative end-of-life treatment pathways. The investigated alternative end-of-life pathways are (i) incineration in a cement plant, (ii) incineration in a dedicated incineration plant, and (iii) production of infills for artificial turfs. The results show that the recycling of ELTs for material recovery has lower environmental impacts in the categories global warming, particulate matter and resource use compared to end-of-life pathways that target energy recovery.
