Globally, about 4 billion waste tires are buried or stockpiled, with approximately 1.8 billion new tires discarded each year. Through pyrolysis processing, these tires can be converted into valuable by-products—including pyrolysis carbon black (PCB). On average, every 10 kilograms of automotive tires contains roughly 3 kilograms of carbon black, resulting in a massive annual output of this material. So, what are the industrial uses of this abundant carbon black resource?
With global carbon black production reaching around 14 million tons annually, refined pyrolysis carbon black is emerging as a sustainable alternative across multiple industries. The following are its main application sectors and their respective market shares.
Refined pyrolysis carbon black is primarily used in tire production, especially for medium- to low-performance tires. After post-treatment, it can meet the requirements for grades like N330, N550, and N660.
About 20% of PCB is applied in industrial and automotive rubber products where material strength and resilience are important but not at tire-grade levels. Common uses include:
Roughly 10% of refined PCB is used in plastics manufacturing and pigment formulations. Although its dispersion and gloss may not match high-end pigments, it delivers acceptable performance for cost-sensitive applications.
Carbon black from tyre pyrolysis plant cannot be directly used in most industrial applications due to its coarse structure and impurities, its value can be significantly enhanced through Beston’s combination process of carbon black grinding and granulation. This process can achieve:
Pyrolysis carbon black is more than just a by-product—it’s a practical, resource-saving material with growing relevance across multiple sectors. As pyrolysis technology evolves, the demand for this sustainable carbon source is likely to expand.
