Abstract: The role of environmental engineers expands from end-of-pipe treatment to sustainable management of natural and engineered systems. Sustainability assessment is an evaluation of potential environmental, economic and social impact of a system over its life. Such assessment enables technology development, comparison and improvement from a system perspective. This presentation introduces the application of life cycle environmental impact assessment and cost analysis to evaluate the treatment technologies for nutrient management. The talk focuses on the assessment of onsite wastewater treatment systems (OWTSs) including conventional systems, the advanced systems consisted of aerobic treatment units (ATUs) and passive nitrogen reduction systems (PNRs). The assessment results shed the light on the strategies to improve the sustainability of OWTSs.
