The operation of wastewater treatment plants results in direct emissions, from the biological
processes, of greenhouse gases (GHG) such as carbon dioxide (CO2), methane (CH4), and …

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 review …

Abstract Ammonia (NH 3), as a prevalent pollutant in municipal wastewater discharges, can
impair aquatic life and have a negatively impact on the environment. Proper wastewater …

An elaborate model was developed to estimate on-site and off-site greenhouse gases
(GHGs) generated from wastewater treatment plants (WWTPs). The model was applied to a …

Greenhouse gases (GHGs; particularly, CO 2, CH 4, and N 2 O) emission from wastewater
treatment systems (WWTS) is one of the inevitable concerns for sustainable development …

The paper presents energy and carbon footprints of sewage treatment plants (STPs)
operating at different scales and using different technology options based on primary data …

Anaerobic digestion is a popular unit operation in wastewater treatment to degrade organic
contaminants, thereby generating biogas (methane-rich gas stream). Catalytic …

Life cycle assessment (LCA) is a tool for determining a product or a process's environmental
