Achieving Sustainable Energy Recovery and Environmental Protection Through Anaerobic Process Optimization

Dear Colleagues,

Among all the available renewable energies, energy obtained from biogas produced from organic sources such as urban and industrial wastewater, organic solid waste, and agricultural residues has become widespread. Considering the urge to employ more and more renewable energy, it becomes of increasing interest to implement anaerobic process technologies with the aim of converting carbonaceous resources into biogas. Process engineering, mathematical models and control strategies can aid optimal operational performance of these technologies. While extracting energy, it is important to consider the environmental sustainability of anaerobic technologies both in terms of solid and liquid residuals and in terms of gas emissions. When exploring the potential of anaerobic digestion, environmental policy and prescribed legislation needs to be investigated.

Based on this, the Special Issue would like to collect works dealing with the following:

• Environmental sustainability of anaerobic technologies;
• Life-cycle assessment of anaerobic technologies;
• Role of anaerobic technologies within the context of circular economy;
• Comparative analyses of the impact of different feedstocks on biogas production;
• Nature-based anaerobic technologies;
• Carbon footprint analyses of anaerobic technologies;
• Post-treatment technologies for anaerobic treatment residuals;
• Experimentation of innovative anaerobic technologies;
• Optimization of biogas production through process engineering, pretreatments and feeding strategies;
• Mathematical modelling approaches applied to anaerobic technologies;
• Control strategies applied to anaerobic technologies;
• Engineering techniques for biogas production enhancement;
• Environmental policy on anaerobic technologies.

In line with the selected topics, the type of articles welcome to this Special Issue are as follows:

• Research works consolidating findings already available in the literature;
• Research works proposing novel ideas;
• Well-structured research works presenting negative outcomes;
• Review articles.

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.
