Microalgae, discovered to have the ability of contributing 60 % of oxygen in the atmosphere by using carbon dioxide for photosynthesis, are abundantly available in the environment. They can survive and grow rapidly even in inconsiderate conditions. Culturing microalgae is environment friendly because they do not require pesticides, whereas their residual biomass can be used as fertilizers. They are found to have the potential to produce biofuel: when carbohydrates of microalgae are fermented and further processed to produce bioethanol and biogas. Moreover, their lipids can be extracted to produce biodiesel. This present work focuses on how to recycle and reuse microalgal biomass, as spent microalgal biomass (SMAB) is constituent of 70 % of the entire microalgal biomass. SMAB is microalgal biomass which can be obtained from its primary use such as lipid extraction. Large-scale production of biodiesel from MAB will accumulate huge amount of waste de-oiled algal biomass (DAB) which can be further processed for other purposes like fertilizers, biofuel, food supply for microbes, etc.
