In this work, five scenarios were compared from a LCA perspective for sewage generated from a mid-sized city in India. The scenarios compared include conventional treatment and four-nutrient recovery systems (chemical precipitation, microbial fuel cell, ion-exchange, microalgae cultivation). No previous studies had compared the LCA of nutrient recovery systems that has been mentioned above. In addition, the present study, attempts to conduct attributional LCA for all 5 scenarios and aids in identifying the best performing alternative for conventional treatment method in terms of its environmental performance. Furthermore, this is the first work to report the LCA of nutrient recovery in Indian context. The objective of this work comprises of 1. Estimate the N and P balance of different nutrient recovery systems; 2.
