Special Issue Information

Dear Colleagues,

Wastewater treatment plants produce large quantities of biological sludge that must be subjected to treatment before utilization or disposal since it contains partially degraded organic matter, nutrients, pathogens, and various toxic organic compounds, such as surfactants, hydrocarbons, and residues derived from plastics.  In this context, anaerobic digestion (AD) can play a primary role in sludge management, as it allows for the required biological stabilization and energy recovery through biogas production at the same time. Nevertheless, due to its complex characteristics, sewage sludge is often barely degradable under conventional anaerobic processes. Therefore, adequate methodologies are necessary to overcome the digestion limitations of sewage sludge. In this regard, scientific research in recent years has taken different directions. The main approaches for the enhancement of anaerobic digestion processes can be summarized as optimization of the process parameters, co-digestion, sludge pre-treatment, additive supplementation, optimization of bioreactor configurations, development of innovative digesters, and application of genetic technologies.

The Special Issue welcomes papers focused on the latest knowledge and innovations concerning the anaerobic digestion of sewage sludge. The papers must be original and provide a significant contribution to the scope of the Special Issue.

Thank you for your contributions.

Manuscript Submission Information

Manuscripts should be submitted online at 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. Fermentation is an international peer-reviewed open access monthly 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.
