Godavari Biorefineries Limited (BSE: 544279 | NSE: GODAVARIB) has been granted a patent by the European Patent Office for its invention, “A Biofiller for Rubber Reinforcement.” The development marks another step in the company’s efforts to expand its renewable chemistry portfolio into advanced materials for industrial applications.
The patented biofiller is developed from lignocellulosic biomass and is designed as a biodegradable and eco-friendly alternative for use in rubber reinforcement. The material can partially replace conventional carbon black in tyres and other rubber products while maintaining or improving key mechanical properties.
The innovation has potential applications across a range of products, including tyres, footwear, belts, bags and other industrial rubber goods. The manufacturing process is designed to be scalable and could offer both environmental and economic benefits by reducing dependence on conventional fossil-based reinforcing materials.
Samir Somaiya, Chairman and Managing Director, Godavari Biorefineries Limited, said, “At Godavari, we have always looked at biomass not simply as a feedstock, but as a starting point for creating new products and new possibilities. The challenge with any bio-based alternative is not only to replace a conventional material, but to prove it can perform reliably in real-world applications.”
“This biofiller brings together renewable biomass, materials science and industry requirements. The European patent is a recognition of the innovation behind this approach and another step towards embedding sustainability into all our processes,” he added.
Carbon black is widely used in rubber compounds to provide strength, durability and performance. Developing renewable alternatives that can reduce the use of conventional carbon black while maintaining the required properties presents a significant challenge in materials science.
Dr Sangeeta Srivastava, Executive Director, Godavari Biorefineries Limited and co-inventor of the patent along with Manisha Jadhav and Prof Vinod Malshe, said, “Carbon black plays an important role in rubber reinforcement, delivering the strength, durability and performance that demanding applications require. Developing a bio-based filler that can partially replace carbon black while maintaining comparable performance, along with the advantage of renewable sourcing, is a significant materials science challenge.”
“At Godavari, we are working at the intersection of performance and sustainability, exploring renewable alternatives that can help reduce dependence on fossil-based reinforcing materials without compromising the performance of rubber compounds,” she added.
The European patent further expands Godavari Biorefineries’ intellectual property portfolio and reflects the company’s continued focus on research and innovation in renewable materials. By developing products from biomass for applications beyond traditional sectors, the company is working to create new opportunities for sustainable industrial materials. The biofiller innovation represents another addition to Godavari Biorefineries’ efforts to combine scientific research, renewable resources and industrial performance in the development of next-generation products.
