Water and Wastewater Treatment Futures: Sustainable Solutions for a Circular Economy

Dear Colleagues,

Ensuring sustainable access to clean water is one of the greatest global challenges of our time. Growing water demand, climate change, and environmental pressures require innovative and integrated solutions that enable efficient treatment, safe reuse, and sustainable management of water resources. Conventional treatment technologies, while effective, often rely on energy-intensive processes and generate significant environmental impacts.

This Special Issue, "Water and Wastewater Treatment Futures: Sustainable Solutions for a Circular Economy" focuses on recent advances and emerging strategies to address these challenges. Papers on innovative approaches that improve the sustainability of water and wastewater treatment, with a focus on resource recovery, energy efficiency, and environmental safety are welcome. Topics of interest include advanced treatment technologies for contaminants of growing concern, processes inspired by the circular economy, hybrid and nature-based solutions, and water reuse strategies tailored for industrial, agricultural, and municipal applications.

This Special Issue aims to provide a comprehensive overview of the latest advances in sustainable water research and practice, creating a platform for scientists, engineers, and industry professionals to share knowledge and foster innovation for a resilient water future. Particular attention is paid to design methodologies that address challenges related to sustainability, socioeconomics, and science, as well as integrated approaches to sustainable development. Our goal is to define and quantify sustainability, measure it, and monitor it, which involves sustainability tools, sustainability applications, sustainability-related policies and legislation, etc. The integration of digital tools, monitoring systems, and process intensification approaches is also strongly encouraged.
