rCB Certification

Rathi Group has earned ISCC EU certification and renewed its ISCC Plus status for a third consecutive year, strengthening its position across certified circular tire-recycling supply chains.

A Milestone in Circular Development

The dual accreditation marks a significant step in the company’s circular development strategy, reflecting a consistent focus on transparency and verified sustainability across the tire recycling value chain, from end-of-life tires through to the production of circular materials and fuels. Third-party certification is what turns a recycling claim into an audited, traceable fact, and this milestone puts that verification at the center of the producer’s offering.

Why rCB Certification Matters for Manufacturers

Recovered carbon black produced through tire pyrolysis is only as credible as the chain of custody behind it. ISCC Plus offers three ways to track certified material through a supply chain: physical segregation, controlled blending, and mass balance. For compounders and product brands, rCB certification means they can source recovered carbon black into rubber, plastics, and coatings with a verifiable, audit-ready sustainability story rather than an assumed one. As brands and original equipment manufacturers tighten their sustainable-sourcing targets, verified third-party chain of custody is becoming the gate that opens premium and regulated markets.

From End-of-Life Tires to Circular Materials

Recovered carbon black is recovered by pyrolyzing end-of-life tires, a conversion that also yields pyrolysis oil and recovered steel. Certification is what allows this circular output to move through a multi-step supply chain while preserving its identity and value. It connects tire recyclers directly to the manufacturers now blending rCB into new rubber compounds, giving downstream buyers confidence that what they purchase is genuinely derived from waste rather than virgin fossil carbon. Keeping the recovered carbon black and its co-products inside a single loop displaces virgin materials and extends the value of every scrap tire.

ISCC EU and ISCC Plus: Serving Fuel and Materials Buyers

The two schemes address different markets, and holding both signals readiness on each. ISCC EU supports the fuel and energy sector, while ISCC Plus extends certification across all markets and products linked to alternative and circular feedstocks. A producer that carries both can serve buyers across recovered-fuel and circular-material channels, treating a feedstock stream as a flexible, multi-route resource. That breadth matters because it rewards recyclers whose material can verifiably plug into a certified supply chain, wherever the buyer sits.

Certified rCB for a Circular Supply Chain

For project developers and rubber manufacturers, certified recovered carbon black is a mature, well-scrubbed material stream that meets sustainability sourcing targets. The mass balance route lets compounders scale circular content without rebuilding every product formula.
