MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202541133960 A) filed by V. Ayyappan, Tenkasi, Tamil Nadu, on Dec. 31, 2025, for 'sustainable bioplastic composition derived from agricultural waste.'
Inventor(s) include P. Muthulakshmi; E. A. Mohamed Ali; V. Ayyappan; T. Arun Srinivas; and M. Rajkumar.
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 discloses a novel sustainable bioplastic composition and its 5 . manufacturing process, Wherein agricultural waste and renewable plant sources are converted into high-performance biodegradable plastic materials. The bioplastic comprises modified starch (50-70% w/w) extracted from agricultural waste such as potato peels, cassava residues, and com processing waste; cellulose nano/microfibers (10-30% w/w) from crop residues like rice straw, wheat straw, 10 and sugarcane bagasse serving as reinforcing agents; natural plasticizers (5-15% w/w); plant-based binding agents (5-10% w/w); and optional functional additives (0-5% w/w). The synergistic composite exhibits tensile strength of 15-40 MPa, comparable to conventional plastics, while achieving complete biodegradation within 60-180 days in natural environments. The manufacturing process involves 15 agricultural waste pre-treatment, polymer extraction and modification, fiber processing, compounding, and forming through various techniques including casting, extrusion, injection molding, and compression molding. The invention provides superior performance compared to existing bioplastics while being 30- 75% more cost-effective, uses only waste and non-food sources eliminating food- 20 crop competition, achieves 87% lower carbon footprint than conventional plastics, and is scalable from village to industrial level. Applications include food packaging, agricultural films, disposable cutlery, shopping bags, and various consumer products. The invention addresses critical global challenges of plastic pollution and agricultural waste management while providing environmental, social, and economic benefits, positioning it as a transformative technology for sustainable materials and circular economy."
