EU Best Practices on wastewater treatment: energy efficiency and sludge valorisation solutions catalogue

This Regional Reference Catalogue has been developed as part of the EU4Green Recovery East programme to showcase innovative practices in energy-efficient and climate-resilient wastewater treatment from across the European Union.

It is designed to serve as a strategic planning tool and resource for Armenia, Azerbaijan, Georgia, Moldova, and Ukraine to work toward modernising their wastewater infrastructure and advancing their environmental and climate objectives.

The catalogue is intended to serve as a reference and knowledge-sharing resource for wastewater utilities, public authorities, technical operators, planners, policymakers, and other stakeholders involved in the modernisation and sustainable management of wastewater infrastructure.
