MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202611002264 A) filed by Indian Institute Of Technology, Roorkee, Uttarakhand, on Jan. 8, for 'method for detection of microplastics released from waste plastic modified asphalt mixtures.'
Inventor(s) include Deb, Soumyadeep; Kumar, Praveen; and Saboo, Nikhil.
The application for the patent was published on Feb. 13, under issue no. 07/2026.
According to the abstract released by the Intellectual Property India: "The present disclosure relates to a first-of-its-kind integrated testing framework for evaluating microplastic generation from RWP-modified asphalt mixtures in both loose and compacted states. The combination of realistic simulation, solvent-assisted segregation, and fluorescence microscopy detection provides a robust, accurate, and reproducible method for identifying potential microplastic release. The novelty resides in the dual-stage evaluation approach and its ability to differentiate and quantify microplastic release tendencies across different modification processes and mixture states. The results conclusively confirm that RWP-modified asphalt mixtures-particularly those prepared by the wet modification process-exhibit negligible microplastic release under laboratory-simulated conditions, thereby validating their environmental safety and sustainability. Thus the present dsisclosure provides a scientific foundation for the standardization of microplastic assessment methods in bituminous materials and supports the environmentally responsible use of recycled plastics in road construction."
