Biodiesel production from discarded fish waste for sustainable clean energy development

The marine fishery industry is an activity of great economic importance in India. Industrial fish processing operations generate a significant amount of wastes, which contains long-chain fatty acids. The crude fish oil from the waste parts of marine fish is considered to be alternative source of low-cost feedstock for biodiesel production. The aim of the present study is to utilize the discarded fish wastes for generation of biodiesel. The experimental result shows that the microwave lipid extraction has approximately 50% more efficiency as compare to conventional method. The transesterification of the extracted lipid from discarded fish-waste material shows efficient conversion into biodiesel through microwave. The Gas chromatography–mass spectrometry analysis shows the presence of good quantity of palmitoleic acid, palmitic acid, oleic acid and eicosapentaenoic acid which is essential biodiesel components.
