Advanced Technologies for Energy and Resource Recovery from Water and Wastewater

Dear Colleagues,

In the face of the global challenges of increasing energy demand and limited natural resources, technologies for energy and resource recovery from water and wastewater are becoming a key component of sustainable development. Through this Special Issue, entitled "Advanced Technologies for Energy and Resource Recovery from Water and Wastewater" of our journal Energies, we invite you to discover the latest breakthroughs that are changing the way we view water and wastewater management.

From advanced membrane and bioelectrochemical technologies to hybrid systems and smart digital solutions, the authors of the works published in this Special Issue share unique developments that not only minimize waste, but also transform it into valuable products. Each article in this Issue acts as a step forward towards a more efficient, economical and environmentally friendly future.

We invite you to read on and discover the potential innovative technologies that turn challenges into opportunities—for science, industry and society. Now is the time for innovative approaches to water and energy management. Join the discussion and be a part of this revolution!

Topics of interest for publication include, but are not limited to, the following:

• Energy recovery technologies:
• Anaerobic digestion and biogas production;
• Bioelectrochemical systems (e.g., microbial fuel cells, microbial electrolysis cells);
• Thermochemical processes for energy recovery;
• Integration of renewable energy in water and wastewater treatment systems.
• Resource recovery innovations:
• Recovery of nutrients (e.g., phosphorus, nitrogen);
• Extraction of valuable compounds (e.g., bioplastics, biochar, rare earth elements);
• Membrane-based separation technologies for resource recovery;
• Circular economy approaches in water and wastewater management.
• Advanced treatment technologies:
• Hybrid and multi-stage treatment systems;
• Nanomaterials and advanced catalysts for resource and energy recovery;
• Sustainable approaches to desalination and water reuse;
• Digital and smart technologies for optimizing treatment processes.
• Environmental and economic assessments:
• Life cycle assessment (LCA) of recovery technologies;
• Techno-economic analysis of innovative treatment processes;
• Policy frameworks and incentives for implementing recovery technologies;
• Case studies demonstrating successful industrial applications.
• Future perspectives and innovations:
• Emerging technologies for decentralized resource recovery;
• Climate-resilient water and wastewater management systems;
• Cross-sectoral approaches to resource and energy recovery;
• Artificial intelligence and machine learning in system optimization.

This Special Issue welcomes original research articles, reviews, and case studies that contribute to advancing the science, technology, and practical applications of energy and resource recovery from water and wastewater.

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.
