The patented technology is designed to partially replace carbon black in rubber products, including tyres, footwear, belts and industrial goods.
Godavari Biorefineries has secured a European patent for its biofiller technology developed for rubber reinforcement. The European Patent Office granted patent EP3313916 on August 12, 2026, covering an invention titled “A Biofiller for Rubber Reinforcement.” The company disclosed the development to the National Stock Exchange of India and BSE under Regulation 30 of the SEBI Listing Obligations and Disclosure Requirements Regulations, 2015.
The patented technology is intended to provide an efficient, cost-effective and biodegradable alternative to conventional carbon black, which is widely used to reinforce rubber products. The biofiller is engineered to partially replace carbon black while maintaining or improving important mechanical properties.
According to the company’s disclosure, the invention also includes a scalable manufacturing process designed for industrial applications. Its potential uses extend across tyres, footwear, belts, bags and other industrial rubber goods, creating opportunities for more sustainable material solutions within the rubber industry.
The technology combines performance, cost and environmental considerations by using a biodegradable material in place of a portion of conventional carbon black. If commercialised successfully, it could support manufacturers seeking to reduce their dependence on traditional reinforcement materials while maintaining product performance.
The patent grant strengthens Godavari Biorefineries’ intellectual property portfolio and highlights its focus on developing bio-based technologies for industrial applications. However, the company’s disclosure does not specify a commercial production timeline, production capacity, customer partnerships or confirmed supply agreements with tyre and rubber manufacturers.
The development could attract attention from rubber processors and manufacturers exploring alternatives that support material efficiency and sustainability. Further information on scale-up, commercial validation and market adoption will be important in determining the technology’s broader industrial impact.
