New Research on Anaerobic Digestion: Second Edition

Dear Colleagues,

Organic waste is a significant global concern, with large amounts generated from households, industrial processes, and agricultural activities. One widely accepted biological treatment technology for this waste is anaerobic digestion (AD). Historically, AD has focused on producing biogas and a nutrient-rich effluent. Biogas is a renewable energy source that can reduce reliance on fossil fuels. However, AD has evolved to also yield other high-value bioproducts, such as volatile fatty acids (VFAs) and biohydrogen, which can be used as building blocks in various industrial processes or as a clean energy source. AD can contribute to creating circular economies and has the advantage of utilizing a wide range of substrates while avoiding the need for sterile working conditions. Despite its potential, some bottlenecks remain, including techno-economics, bioreactor hydrodynamics, the separation of end-products, and understanding microbial interactions. This Special Issue calls for novel research to address these challenges and cutting-edge research on substrate pretreatment, dry digestion, microbial community analysis, emerging biogas applications, and downstream processing, including biogas upgrading. 

This is a second Special Issue, following the success of “Anaerobic Digestion of Waste”, which can be viewed here: https://www.mdpi.com/journal/fermentation/special_issues/anaerobic_digestion1

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. 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 2100 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.
