MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202511122347 A) filed by Prof. Rajul Rastogi; Dheeraj Kumar; Mamta Verma; and Shubham Gupta, Moradabad, Uttar-Pradesh, on Dec. 5, 2025, for 'system and method for sustainable management, extraction, and recycling of gadolinium from contrast agents used in diagnostic radiology.'
Inventor(s) include Prof. Rajul Rastogi; Dheeraj Kumar; Mamta Verma; and Shubham Gupta.
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: "The invention provides an integrated system and method for sustainable collection, extraction, and recycling of gadolinium originating from gadolinium-based contrast agents used in magnetic resonance imaging. Patients are provided with specialized urine collection kits that safely capture gadolinium-rich urine for twenty-four hours following contrast administration. The collected samples are aggregated in monitored pooling stations and transported to a recovery facility, where multi-stage extraction using ion exchange, adsorption, membrane filtration, precipitation, or electrochemical separation isolates gadolinium from the biological matrix. Residual contrast agent remaining in partially used vials is recovered through controlled rinsing and merged with the extraction stream. The recovered gadolinium undergoes purification to produce high-purity gadolinium oxide, gadolinium chloride, or similar compounds suitable for reuse in pharmaceutical, electronic, and industrial applications. The system is modular, scalable, and environmentally responsible, establishing a circular economy framework that prevents gadolinium contamination and reduces dependence on mined rare-earth resources."
