Mitigating N2O emission from wastewater treatment processes

Start date

End date

October 2023


Wastewater industry confronts challenges to meet net zero by 2030 in advance of UK's 2050 goal. There is a need for urgent action to mitigate greenhouse gas (GHG) mission. Nitrous oxide (N2O) contributes largely to total GHG emission in wastewater treatment processes, produced by multiple microorganisms and fluctuates in the dynamic reactor environment. We propose a combination of interdisciplinary methods - analytical chemistry, molecular biology, and AI-assisted computer modelling - to develop a reliable and robust toolkit to address the two challenges above. This toolkit will have the potential for practical application to existing and future full-scale wastewater treatment systems for N2O emission control.
