Microalgae as Bio-Converters of Wastewater into Biofuel and Food

Abstract

The extensive usage of lands for the production of food and biofuels have initiated an intensive search for the next generation of feedstocks on marginal lands. The use of wastewater as a source of key nutrients would significantly reduce the cost and energy requirement. Currently, algal-based products are produced on the industrial scales in Asian and European countries. With the ability to grow on wastewaters, converting generated biomass into the pharmaceuticals, biofuels and food supplements microalgae represent a unique and green solution for three major challenges humanity is facing: shortages in food and energy and man-made pollutions.
