Current Trends in Anaerobic Digestion Processes, Volume II

Dear Colleagues,

Given the growing demand for green energy in developed and developing countries, biogas production from biomass and waste is a technology that is used to produce renewable methane. This can be obtained as biogas or biomethane (through a successive upgrading step). Different substrates can be used in the anaerobic digestion process, such as energy crops, waste, residual biomass, as well as food waste. Feedstock logistics, plant operation optimization, and biogas utilization in engines and turbines are key topics that must be carefully analyzed for the successful planning of biogas and biomethane projects. Process optimization should be based on the comprehension of biogas yields from different substrates, the analysis of pre-treatment processes of the raw materials, the optimization of pH in the reactor, the optimization of retention time, the optimization of volatile matter degradation efficiency, and the process integration and heat integration to reduce waste heat production (e.g., from CHP units). Together with these conventional aspects, other innovative technologies have to be developed to purify biogas through fermentation, separation of CO₂, hydrogenation of CO₂, use of biochar in the digester, or biogas purification.

This Special Issue on "Current Trends in Anaerobic Digestion Processes, Volume II" aims to curate novel advances in biogas production and use, focusing both on modeling and experimental campaigns. Topics include, but are not limited to, the following:

• Modeling of anaerobic digestion and biogas production;
• Organic substrate characterization and pre-treatment;
• Biogas purification and biomethane production and use;
• Biogas combustion in engines and turbines.

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. Processes 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 2400 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.
