MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202641019055 A) filed by Sri Krishna College Of Engineering And Technology, Coimbatore, Tamil Nadu, on Feb. 19, for 'sustainable conversion of sugarcane leaves into bio-based plastics and composite materials.'
Inventor(s) include C Rajendran.
The application for the patent was published on Feb. 27, under issue no. 09/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a sustainable process for converting sugarcane leaves (100), an underutilized agricultural residue, into biodegradable plastics and composite materials (112). The process involves pretreatment and delignification (102) of sugarcane leaves followed by cellulose extraction and purification (104) to obtain high-quality cellulose. The extracted cellulose is subjected to chemical modification or fermentation (106) to improve polymer compatibility or to produce biodegradable biopolymers. Polymer blending and compounding (108) with biodegradable matrices result in eco-friendly plastic and composite products. A novel feature of the invention includes the recovery of silica-rich ash (105) during processing and its optional incorporation as a functional filler to enhance material properties. The invention provides an environmentally benign, waste-to-wealth solution that reduces agricultural residue burning and dependence on petroleum-based plastics while supporting circular economy and sustainable material development."
