MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202631063135 A) filed by Jis College Of Engineering, Nadia, West Bengal, on May 19, for 'a sustainable method to modify bitumen using waste plastic improving mechanical and thermal properties.'
Inventor(s) include Ananya Barman; Dr. Tanmoy Dutta; Dr. Jit Chakrobarty; Brishti Das; Adrija Biswas; Adrija Roy; Ahana Pradhan; and Ankita Roy.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a high-performance polymer-modified bituminous composition and a scalable method for the synthesis thereof using post-consumer plastic waste. The process involves the systematic decontamination and shredding of waste plastics-such as polyethylene, polypropylene, and polystyrene-followed by their controlled integration into a heated bitumen matrix under optimized thermomechanical conditions. By maintaining a precise temperature range of 160^C to 170^C and employing continuous mechanical stirring, the invention achieves a stable, homogeneous blend that significantly improves the resistance of road pavements to rutting, thermal cracking, and moisture damage. This invention provides a technically robust and environmentally sustainable solution for infrastructure development, simultaneously addressing the global challenge of plastic waste management while reducing the economic costs associated with pavement maintenance."
