One of the real issue of disposable pads is its non-biodegradability which increases menstrual waste produced. Our study carried out aims at synthesizing sanitary napkins with conventional three layered design using natural waste. Starch based porous bioplastic was synthesized as top sheet. Core absorbing layer consisted of thin cotton layer impregnated with cellulose based hydrogel synthesized using CMCNa, starch and malic acid. The cross-linking property of malic acid was found to be better than citric acid. A fibrous sheet synthesized from Banana stem fibre, Pineapple leaf fibre and coir acted as additional support layer. Gelatin obtained from fish scale was used as an adhesive. Soil burial test for biodegradability gave a remarkable weight loss by 82% and 77.16% of hydrogel and bioplastic respectively within 60 days. Upon performing absorption capacity test and wet back test, the assembled sanitary napkin proved to be efficient than some of the commercially available products. Methanolic extract of Psidium guajava worked best against E.coli and S.aureus when compared with extracts of Azadirachtaindica and Justicia adhatodaby AST to increase shelf-life. Thus, the present study gives improved insight and cost effective method for synthesis of biodegradable sanitary napkins using sustainable resources.
