SUSTAINABILITY OF CHLORELLA PYRENOIDOSA FOR THE SIMULTANEOUS TREATMENT OF WASTE WATER AND BIOFUEL PRODUCTION: A REVIEW
Dr. Rohit Sharma*, Dr. Nishesh Sharma and Dr. Avanish K. Tiwari
ABSTRACT
Continued use of fossil fuels is now widely recognized as unsustainable because of diminishing supplies and the contribution of these fuels to the increased carbon dioxide concentration in the environment. Microalgae are considered as a most capable feedstock for the generation of biofuels due to its several advantages, compared to the feedstock of first- (food feedstock) and second- (non-food feedstock) generation biofuels. It is a photosynthetic organism that converts carbon dioxide to potential biofuels, foods, feeds and high-values bioactives. The integration of microalgae growth with anaerobic digestion could significantly improve the economics and energy balance of biofuels production. Nutrient removal, in particular nitrogen and phosphorus; and COD reduction from wastewater is a developing regulatory need and the use of algae cultivation could create a unique integration between waste treatment and biofuel production. Therefore, the study discusses about the design, development and integration of microalgal production using anaerobic digestion under outdoor conditions. This decreases the production cost of microalgae as well as biofuel.
