Unravelling the dynamics of nitrous oxide production in wastewater systems (2018–2021)
Nitrous oxide (N2O) is a potent greenhouse gas and a major consumer of stratospheric ozone. In Australia, N2O emissions contribute up to 50% of the total carbon footprint of wastewater treatment systems. However we have a lack of understanding of the pathways and factors regulating N2O production in such engineered biological systems. This project aims to unravel the dynamics of N2O production in wastewater treatment systems by combining continuous stable isotope tracing techniques with innovative experimental design and sophisticated mathematical modelling. The knowledge generated in this project will significantly improve the understanding and management of N2O production from wastewater treatment systems.
