Special Issue Information
Dear Colleagues,
Wastewater contains various nutrients and organic compounds that can be recovered and converted into energy products. The recovery and reuse of resources from wastewater is an essential part of a circular economy and sustainable development. Various wastewater treatment technologies, such as anaerobic digestion (AD), microalgae, and microbial fuel cells (MFCs), have been studied to clean and recycle water and also convert the impurities in wastewater into energy products. AD is an effective technology for converting organic compounds in wastewater into biogas, which can be upgraded to renewable natural gas. The cultivation of microalgae using wastewater can remove the fertilized nutrients in the wastewater and, at the same time, allow algal biomass to be obtained for the production of biofuels. MFCs can directly convert chemical energy stored in organic compounds in wastewater into electricity via redox reactions under mild conditions. These wastewater treatment technologies provide promising methods for the development of a sustainable water system and sustainable energy production in a circular economy. Recently, various innovative approaches, such as process integration, nanomaterials, and artificial intelligence, have been studied to fully exploit the economics and sustainability of wastewater-to-energy technologies.
This Special Issue aims to collect original research papers and comprehensive reviews from global experts to share the most recent advances in the development of various sustainable and cost-effective wastewater-to-energy treatment technologies. Topics of interest for publications include, but are not limited to, the following:
- The anaerobic digestion of wastewater;
- Microalgae cultivation on wastewater;
- Microbial fuel cells using wastewater;
- The process of integration of wastewater-to-energy treatment technologies;
- The techno-economic analysis and life cycle assessment of wastewater-to-energy treatment technologies;
- Nanomaterials applied to wastewater-to-energy conversion;
- The application of artificial intelligence in wastewater-to-energy conversion.

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 100 words) can be sent to the Editorial Office for announcement on this website.
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.
