Birla Carbon Advances Circularity with Waste-Tyre Based Carbon Fillers
Birla Carbon is scaling up its production of waste-tyre-derived carbon fillers, aiming for these circular materials to make up to 10 % of its global product portfolio. The company markets these solutions under its “Continua” brand and says the material is produced from end-of-life tyres and can partially substitute traditional carbon black across tyres, rubber goods, coatings, inks, and plastics.
According to the company, the demand for these sustainable carbonaceous materials is growing faster than conventional carbon black markets, driven by rising sustainability goals across mobility, tyre, and broader rubber-goods industries. Quality remains a key focus: Birla insists the waste-tyre-based filler meets high-performance standards to be viable in demanding applications like tyres.
Looking ahead, wider adoption will depend on regulatory support, collaborations with tyre-pyrolysis partners, and wider customer uptake. Birla Carbon also has a circularity target to repurpose 300,000 tonnes of end-of-life tyres annually through its Continua™ SCM programme by 2030. Birla Carbon
For the tyre sector, this development signals an increasingly mature supply-stream option for reinforcements and fillers that have traditionally relied on virgin carbon black. The structural challenge of scaling waste-tyre-feedstock-based solutions is being addressed, which may reshape cost structures, raw-material sourcing, and life-cycle profiles in tyre manufacturing.

This shift by Birla Carbon emphasises how “used tyres” are no longer just waste, they’re becoming feedstock for next-generation materials. For the tyre industry, that means two things: reducing reliance on traditional carbon black and integrating circular-economy materials without compromising performance.
As tyre makers face pressure on sustainability, cost, and regulations, the availability of high-quality waste-tyre-based fillers offers real strategic leverage. However, success will depend on the tyre industry embracing these materials, designing compounds around them, and aligning with supply-chain partners that can guarantee consistency. The ripple effects across material sourcing, manufacturing, and aftermarket will be significant.
