Recovered carbon black (rCB) derived from tire pyrolysis has officially received an ASTM International standard, establishing industry-wide specifications that validate its performance and expand its adoption in the global rubber and tire manufacturing industries.

Klean Industries Inc (“Klean”) is pleased to announce that ASTM International’s Committee D36 for Recovered Carbon Black (“rCB”) has approved a new standard for rCB that is a product derived from end-of-life tire pyrolysis recycling technologies. This new standard provides a testing standard that will help differentiate products and provide quality control tools for recovered carbon black producers, tyre pyrolysis operators, and end users. The new ASTM standard published as D8474 describes a thermogravimetric (“TGA”) technique used to determine the amounts of organic residue, overall fixed carbon content, and ash content in recovered carbon black.

As recently published on the ASTM website, Pieter ter Haar from Cictec, an ASTM member, says, “The new standard will be a helpful tool specifically for quality control and can be used for off-take agreements, technical data sheets, and certificates of analysis. This will be most useful for manufacturers, users, and consumers. This standard will improve the adoption of rCB. Recovered carbon black can complement or substitute conventional carbon black in many applications, including producing new, more sustainable tires. 

Alongside Mr. Pieter ter Haar and many other contributing members, Jesse Klinkhamer, CEO of Klean Industries, and Dr. Martin Loffler, Head of Tire Pyrolysis Engineering for Klean Industries, are contributing members of the technical committees for D36 recovered carbon black, which is setting the global standards for the quality and safety of rCB in the global marketplace. 

Industry experts and business leaders believe the D36 standard that classifies recovered carbon black is a step in the right direction.

New ASTM Standard Validates Recovered Carbon Black for Global Markets

With the approval of an ASTM International standard for recovered carbon black (rCB), the tire and rubber manufacturing sectors now have a clear benchmark for performance, quality, and sustainability in carbon black alternatives.

Why This Matters:

✅ Enhances buyer confidence and accelerates procurement of rCB
✅ Opens new markets for circular carbon black applications
✅ Supports ESG initiatives and regulatory compliance
✅ Strengthens commercialization of pyrolytic carbon products
