Recovered Carbon Black Standard

A new classification system for recovered carbon black is set to encourage a full life-cycle view of tires and support fair trade in the material.

Why Classification Matters

The new standard, D8632, was developed by ASTM’s recovered carbon black committee to define product categories and ease trade between producers and users. Recovered carbon black is described as a semi-reinforcing filler obtained from post-consumer rubber products such as tires and conveyor belts.

From Feedstock to Product

Through thermal decomposition, feedstock is converted into oil, gas and raw recovered carbon black, which is then further processed into the final product. The classification format uses the letter R to indicate recovered carbon black, followed by a number for the class of toluene transmittance and a second for the class of inorganic content.

Enabling Fair Comparison

By enabling quality comparisons within a specific category rather than across all rCB products at once, the standard promotes fair competition and helps buyers and sellers establish a common basis for transactions.

Producing Specification-Grade rCB

As classification standards formalise the market, recovered carbon black becomes easier to specify, sell and blend into new rubber.

Klean Industries engineers tire pyrolysis plants that produce consistent, specification-grade recovered carbon black.
