MUMBAI, India, July 11 -- Intellectual Property India has published a patent application (202521048179 A) filed by Indian Institute Of Technology, Bhilai, Chhattisgarh, on May 19, for 'a method of depolymerization of a thermoplastic polymer and a depolymerized product thereof.'
Inventor(s) include Sanjib Banerjee; Priyank Sinha; Sudipta Paul; and Swarup Maity.
The application for the patent was published on July 11, under issue no. 28/2025.
According to the abstract released by the Intellectual Property India: "The present invention provides a nano-catalyst that comprises of a zerovalent iron for the depolymerization of a thermoplastic material through glycolysis. The zerovalent iron is obtained by liquid-phase reduction that occurs in presence of a reducing agent, sodium borohydride. Further, the nano-catalyst exhibits high monomer recovery with a facile reaction setup, lower temperature and faster reaction time. Additionally, the nano-catalyst is magnetically recoverable and reusable thereby resulting in minimum waste. The present invention, therefore, provides a sustainable and cost-efficient method of polymerization of thermoplastic materials for large-scale lab operations and promote circular plastic economy."
