Wastewater based microalgae valorization for biofuel and value-added products recovery

Microalgae are unicellular organisms that have been used in wastewater treatment. A majority of wastewater contains nutrient components like phosphates and nitrates along with organic compounds that favour biofuel recovery. It has been reported that various methods of wastewater systems have been employed such as source-separated systems, activated carbon, hybrid systems and immobilized reactors and simultaneous resource recovery. In this review, we will critically examine the state-of-the-art algal biotechnology for wastewater treatment, especially concerning its potential for valorization. We will also discuss the recent advances in micmalgae systems for wastewater treatment coupled with the bioproduction of value-added products.
