Abstract

Salvinia Molestais commonly found aquatic weed (hydrophyte) which is low in lignin and contains high amounts of cellulose and hemicellulose with lipid content on the surface of the leaves to achieve non-wetting phenomenon. The current work looks at assessing the feasibility of an aquatic plant Salvinia Molestain the production of bio-diesel. The study consisted of carrying out the culturing of the plant under different aqueous conditions for maximum yield, extraction of the leaf, petioles, and stalks for lipid extraction followed by the lipid analysis through FFA (Free Fatty Acid). The culturing of the plant provided insightsintothe space requirement, salinity,and exposure to sunlight. The lipid yield from the dried plant was low and showed an FFA value of 4.2% which necessitated the blending of the lipid extract with waste vegetable oils (Plant lipid content 5%-10% by volume) during the transesterification reaction to yield biodiesel. The thermo-physical characterization of this bio-diesel and bench marking with High-Speed Diesel has been carried out.
