ecoSTP-23 aims to discuss the latest cutting-edge eco-technologies for a sustainable transition in wastewater treatment, reuse, and resource recovery, at urban and industrial scale, giving special attention to the efficient transfer of knowledge into practice. Building a more resilient future for water management needs a transdisciplinary and multi-domain examination, including socio-economic and governance aspects. ecoSTP23 will include hydro-social aspects and the multiple factors that currently frame water management.
