Overall, the environmental performance of MFC was reported to outperform other scenarios including microalgae based nutrient recovery systems. The main attribution of MFC was that it was a single-pot system, where in it recovers nutrients as well as treat the WW simultaneously. Whereas, for microalgae systems, treated WW after secondary treatment was used. Hence, further studies on microalgae are necessary to understand its effect on a combined solution as a nutrient recovery and a raw WW treatment system.
