Abstract
High energy demand and water crisis are two major concern nowadays. Various alternative energy sources have been searched and suggested from the researchers around the world to address this apprehension. Microalgae biofuel have been considered as future fuel. However economic feasibility of biofuel production from microalgae is still challenging due to high production cost. Utilization of wastewater for algal cultivation can reduce the water demand as well as chemical requirement. This chapter includes different wastewater sources which have been used for microalgae cultivation and challenges associated with it.
