A Circular Pathway for Tire Compound Carbon Black
Carbon black is the second largest raw material input by weight in most tire compounds, contributing reinforcing properties, UV resistance and tread durability. Conventional carbon black is produced through the incomplete combustion of petroleum-based feedstocks - a process that is energy-intensive, emissions-heavy and increasingly subject to regulatory scrutiny in key producing markets including China and the EU.
Recovered carbon black (rCB) - derived primarily through the pyrolysis of end-of-life tires (ELTs) - offers a circular economy pathway that addresses both input cost and sustainability objectives simultaneously. The global end-of-life tire stream generates hundreds of millions of units annually, creating a potentially large feedstock base for pyrolysis operations. The carbon black fraction recovered from this process, when properly refined and processed, can substitute for virgin N-grade carbon black grades in select tire compound applications.
Evaluating rCB Quality and Fit
However, the technology is not without complexity. rCB quality varies significantly depending on the pyrolysis process design, feedstock mix, post-processing (pelletizing, activation, refinement) and ash content management. Not all rCB grades are suitable for use in structural or safety-critical tire components, and direct substitution of virgin carbon black without compound reformulation carries performance and compliance risk. Radial Insights helps manufacturers evaluate these trade-offs with rigour.

Quality & Performance Benchmarking
Benchmarking of available rCB grades against your existing compound specifications for performance and processability.
Regulatory & TCO Modelling
Regulatory compliance review under REACH and relevant IATF 16949 quality system implications, alongside total cost-of-ownership modelling comparing rCB integration against continued use of virgin carbon black.
Adjacent Sustainable Input Technologies
We also evaluate adjacent sustainable input technologies including bio-based carbon black derived from biomass feedstocks, precipitated silica as a carbon black partial substitute in green tire compounds, and the use of sustainable process oils (TDAE, MES, RAE) that comply with EU PAH regulations. Our category taxonomy covers the full landscape of tire compound inputs - from conventional sulfur and vulcanization agents to next-generation silane coupling agents and bio-based process oils - allowing us to assess substitution opportunities across your entire formulation portfolio.

Aligning rCB to Your Sustainability Roadmap
For manufacturers with Science-Based Targets (SBTi), ESG reporting obligations under GRI, TCFD or CSRD, or internal Scope 1, 2 and 3 emissions reduction commitments, rCB adoption is increasingly part of the sustainability roadmap conversation. Radial Insights aligns our technology evaluation work to your specific emissions accounting framework, ensuring that rCB integration decisions are quantified in terms of carbon intensity reduction and accurately reflected in your sustainability reporting.
