Wastewater Treatment and Energy Conversion

Dear Colleagues,

Ensuring a sustainable and secure water supply remains one of the most pressing global challenges of the 21st century. As the demand for seawater desalination, wastewater reclamation, and urban water supply continues to rise, integrating wastewater treatment with energy conversion has emerged as a key strategy in sustainable environmental engineering. This approach not only enhances water security but also contributes to global energy sustainability.

The forthcoming Special Issue, “Wastewater Treatment and Energy Conversion”, in Energies aims to explore cutting-edge technologies, system-level innovations, and policy frameworks that transform wastewater treatment infrastructure into dynamic energy–water nexus hubs. By bridging environmental engineering and energy science, this Special Issue will provide academically rigorous, practical, and impactful insights, fostering the development of resilient, low-carbon urban water systems.

We welcome original research and review articles covering topics including, but not limited to, the following:

• Advanced wastewater treatment technologies for enhanced energy recovery and resource utilization;
• Bioelectrochemical systems and microbial fuel cells for sustainable energy production;
• Techno-economic and life cycle assessments of energy-efficient wastewater management strategies;
• Smart and integrated systems for optimizing the energy–water nexus in urban environments;
• Policy and regulatory frameworks supporting the circular economy in wastewater management.

By leveraging Energies’ open access platform, this Special Issue seeks to catalyze interdisciplinary collaboration and accelerate the transition toward sustainable wastewater–energy systems. Contributions to this Special Issue will directly support global sustainability efforts, particularly SDGs 6 (Clean Water and Sanitation), 7 (Affordable and Clean Energy), and 13 (Climate Action).

We invite you to submit your research to this Special Issue and contribute to shaping the future of sustainable water and energy systems. For further details and submission guidelines, please visit https://www.mdpi.com/journal/energies/about or contact us directly.

We look forward to your participation.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Energies is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
