MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202631025393 A) filed by National Institute Of Technology, Rourkela, Orissa, on March 3, for 'method for removing microplastics and/or nanoplastics (mps/nps) from an aqueous medium via faujasite-type zeolite y (na-y) compound prepared utilizing industrial waste.'
Inventor(s) include Gopal, Ms. Sreeshma; and Sen, Dr. Sujit.
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: "Embodiments herein disclose a method for removing microplastics and/or nanoplastics (MPs/NPs) from an aqueous medium using faujasite-type zeolite Y (Na-Y) synthesized from aluminosilicate industrial waste. The method comprises preparing Na-Y through a sono-assisted sequence of calcination of coal fly ash, acid leaching, alkali activation, aging, and hydrothermal crystallization, and contacting an aqueous stream containing MPs/NPs with the synthesized zeolite Y to effect adsorption. The zeolite Y exhibits high crystallinity, mesoporosity, and high specific surface area, enabling at least about 90% removal efficiency under neutral pH conditions."
