MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202431085791 A) filed by Kalinga Institute Of Industrial Technology, Bhubaneswar, Orissa, on Nov. 8, 2024, for 'surface-modified plastic aggregates for high-strength lightweight concrete.'
Inventor(s) include Sanjukta Sahoo.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "This invention presents a method to produce high-strength, lightweight concrete aggregates from non-infectious biomedical plastic waste. By embedding sand onto the surface of plastic particles at high temperatures, a durable, cement-compatible coating is formed, creating a strong bond with the concrete matrix. This sand-coated plastic aggregate addresses the traditional shortcomings of plastic-based concrete, such as poor compressive strength and weak adhesion, by offering an eco-friendly, chemical free alternative to natural aggregates. The invention enables sustainable construction practices, reducing the environmental impact of plastic waste and the depletion of natural aggregates. This innovation transforms biomedical plastic waste into a valuable resource, advancing the construction industry's shift toward greener, more resilient building materials."
