MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202541133958 A) filed by V. Ayyappan, Tenkasi, Tamil Nadu, on Dec. 31, 2025, for 'eco friendly biodegradable sanitary napkin using agricultural waste materials.'
Inventor(s) include S. Shenbagavalli; V. Ayyappan; E. A. Mohamed Ali; 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 an innovative eco-friendly biodegradable sanitary napkin manufactured from agricultural waste materials, specifically pineapple leaf fiber (PALF), com fiber, and sugarcane bagasse. The sanitary napkin comprises a multilayer structure including: (i) a top sheet layer made from processed pineapple leaf fiber providing a soft, breathable, antimicrobial surface; (ii) a distribution 10 layer of fme pineapple fiber for lateral liquid spreading; (iii) an absorption core containing optimized blend of com fiber and sugarcane bagasse (40:60 to 50:50 ratio) offering superior absorption capacity of 150-200 ml; (iv) a backing layer of compressed bagasse or biodegradable bio-tilm providing leak-proof protection; and (v) plant-based adhesive for secure attachment. 15 The invention addresses critical environmental challenges posed by conventional petroleum-based sanitary napkins that take 500-800 years to decompose, by providing a completely biodegradable alternative that decomposes within 90-180 days under composting conditions. The napkin achieves rapid liquid strikethrough ( 5 seconds), high absorption capacity (20-25% superior to 20 conventional), natural antimicrobial properties ( 90% bacterial inhibition), and hypoallergenic skin-friendly composition (pH 5.5-7.5). The product facilitates a waste-to-value circular economy model, achieving 75-85% carbon footprint reduction and generating rural income and employment, positioning it as an affordable alternative with a suggested retail price of ~3-4 per napkin."
