Quantifying, modelling and mitigating process emissions – Masterclass 1

Description

This masterclass series will bring participants up to speed with process emissions of nitrous oxide and methane from wastewater treatment through presenting the key findings from a newly (April 2022) launched IWA publication and sharing the experience of progressive utilities around the world. Four masterclasses will be organised in 2022 by the Climate Smart Utilities Initiative. This first masterclass will set the scene and provide an overview of what process emissions are, an introduction to the IWA Specialist Groups working in the area and a summary of what the series will cover.

Direct process emissions of nitrous oxide and methane are produced during the treatment of wastewater and sewage sludges. These will become a key source of carbon emissions as water utilities shift their energy sources from fossil based to renewables. Whilst work remains ongoing in academia and industry. Much is already understood about quantifying, modelling, and mitigating these emissions.

This first masterclass is hosted by the editors of the IWA publication “Quantifying and modelling of fugitive greenhouse gas emissions from urban water systems” and will be composed by a panel of experts. The first class will cover what process emissions are, why they are important and how we currently quantify and report them in carbon accounting in the water sector.

This masterclass is supported and promoted by IChemE and their Water Special Interest Group. This platform provides a forum for the exchange of ideas and the sharing of experiences in the engineering aspects of water and wastewater treatment.
