Weibold Academy: How to keep improving ELT pyrolysis processes
End-of-life tires (ELTs) represent a significant environmental challenge globally, with over 1 billion tires produced and discarded each year. Their durability and complex composition, which includes a mix of rubber compounds, metals, textiles, and fillers, make them particularly difficult to recycle. Traditional disposal methods like incineration and landfilling not only fail to recover valuable materials but also contribute to environmental degradation. As the world seeks more sustainable recycling practices, pyrolysis—a process of thermal decomposition in an inert atmosphere—has emerged as a promising alternative. This method allows for the recovery of valuable products such as recovered carbon black (rCB) and tire pyrolysis oil (TPO), including limonene, a solvent derived from the degradation of rubber components. However, achieving consistent, high-quality outputs through pyrolysis requires careful control of both feedstock characteristics and process parameters.
