With the new urban wastewater treatment directive in place there are increased pressures to both reduce and recover energy while simultaneously reducing climate impact. It states:
“This Directive should contribute to the progressive reduction of greenhouse gas (GHG) emissions from urban wastewater collection and treatment activities, in particular by further reducing nitrogen emissions but also by promoting energy efficiency and production of renewable energies, and thus should contribute to the 2050 objective of Climate Neutrality […].”
In this seminar, we discuss methods for measuring and modelling these emissions and impacts to help practitioners and researchers to meet the new directive. The presenters represent both wastewater treatment facilities and academia and we believe there is high potential for nice discussions during the Q&A sessions.

One week before the seminar, a Zoom link will be sent out via email to all who registered. We hope to see you there!
