MUMBAI, India, Jan. 2 -- Intellectual Property India has published a patent application (202541123933 A) filed by Vignan's Foundation For Science, Technology and Research, Tenali, Andhra Pradesh, on Dec. 9, 2025, for 'method for manufacturing biodegradable bioplastics from catla catla fish scale waste.'
Inventor(s) include Mr. Solomon Godwin Babu N. D; Dr. Sumalatha Boddu; and Dr. Ramesh Naidu Mandapati.
The application for the patent was published on Jan. 2, under issue no. 01/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a method for producing biodegradable bioplastic utilizing Catla catla fish scale waste as a primary biopolymer source. The method comprises processing fish scales containing collagen and hydroxyapatite, followed by blending the extracted biopolymer with a red-algae-derived natural binder and glycerine as a plasticizer. The mixture is subsequently cast and molded into film-based bioplastic sheets. Characterization using FTIR, TGA, XRD, and EDS confirms the formation of a stable biopolymer network exhibiting thermal stability up to 220 C and partial crystalline structure. The resulting bioplastic demonstrates mechanical strength retention of approximately 85% after stress testing and undergoes complete biodegradation within 60 days under composting conditions. The developed material is suitable for low-temperature packaging and related industrial applications. The invention provides an eco-friendly and scalable solution for converting seafood waste into high-value biodegradable plastic materials, thereby reducing dependence on petroleum-based plastics and supporting circular economy initiatives."
