The life cycle assessment of four different nutrient recovery systems and traditional wastewater treatment were compared in this study. Form the results, it was identified that about 80% of the P present in the effluent can be recovered by employing single-pot system (Microbial fuel cell). Meanwhile, the maximum reduction in global warming potential of 36% was achieved when nutrient recovery system is combined with conventional wastewater treatment. The nutrients recovered from wastewater have significantly decreased the carbon footprint (56-98%) when compared to conventional fertilizer such as diammonium phosphate and urea. The results of this study demonstrate the necessity of single-pot treatment and recovery systems for improved environmental and economic performance. It is necessary to conduct more research on microalgae as a combined technique for nutrient recovery and wastewater treatment.
