Life Cycle Assessment and Its Application in Wastewater Treatment: A Brief Overview

This paper provides a brief review on wastewater treatment system and the application of life cycle assessment (LCA) for assessing its environmental performance. An extensive regarding geographical relevance LCA WWTPs, evaluation sustainable by in both developed developing countries are also discussed. The objective is to identify knowledge gap, improvement methodology WWTPs. A total 35 published articles related (WWT) from international scientific journals were studied thoroughly summarised 2006 2022. found that there lack studies concerning WWTPs consider specific local criteria especially countries. Thus, it important to: (1) assess influence seasonality (i.e., dry wet seasons) impact WWT, (2) investigate impacts focusing site-specific inventory data, (3) evaluate sustainability different processes upgrading system. cost aspects crucial development WWTP. Therefore, must be assessed provide recommendation future policy water industry determining trade-offs toward development.
