Description
Summary:This article is mainly based on the production of biodiesel and bioethanol from waste banana peels and radish leaves. The oily content from both the samples were converted to biodiesel by acid catalyzed and base catalyzed transesterification using methanol and ethanol. The biodiesel so obtained was subjected to analysis in accordance with the American Standard for Testing Materials (ASTM). The carbohydrates were extracted by distilled water and characterized by physical, chemical and biochemical methods. The carbohydrates were subjected to anaerobic fermentation using Saccharomyces cerevisiae to produce bioethanol which was confirmed by the preparation of UV active derivatives namely ethyl benzoate and ethyl salicylate. The highest % yield of fatty acid methyl ester and fatty acid ethyl ester was found to be 75% and 38%, respectively. The yield of bioethanol from banana peels and radish leaves was found to be 1.37% and 1.23%, respectively.
