Mitigating methane emissions from sludge drying lagoons

Sludge-drying lagoons are used in Australia as a convenient and cost-effective method of de-watering wastewater sludge. Methane emissions from these lagoons have been estimated to represent up to two thirds of total greenhouse gas emissions of the wastewater treatment, and will need to be addressed for water utilities to meet emission reduction targets. This project will investigate operational interventions that have the potential to select for novel microorganism capable of oxidising methane as a means of reducing emissions.
