The wastewater sector has a potential in the energy transition for Europe. Don’t underestimate the power of wastewater.

 

 

Transforming municipal wastewater treatment plants (WWTP) from net power consumers into energy neutral or even energy positive service providers is no longer a dream.

 

This was one of the key messages of the POWERSTEP final conference which took place on 16-17 May at the IFAT Trade Fair in Munich, Germany.

Discussions around innovations that enable new Resource Recovery Factories were at the core of this two-day conference which featured POWERSTEP project partners who presented their state-of-the-art research, representatives of related H2020 research and innovation projects working on the circular water economy, and other recognised experts from the field of wastewater treatment.

The participants learned about the European and energy framework in which the WWTP as a renewable energy source operates, whilst also investigating the market deployment potential. Each topic was developed and shaped to meet the IFAT audience expectations: to learn, be questioned and challenge the discussions.
