Advanced Research on Bioenergy and Biofuel Production from Anaerobic Digestion Processes

Dear Colleagues,

The global reliance on fossil fuels, coupled with the existing energy crisis and the global pledge to achieve net-zero emissions by 2050, has led to substantial changes in the global energy mix. Now, more than never, countries all across the world are searching for affordable and standalone renewable sources of energy that can guarantee a reliable energy supply while meeting the demands of consumers. Biomethane and biogas produced by anaerobic digestion processes will play a significant role in the clean energy transition towards net-zero emissions, since these are cheap, decentralized, and well-established systems.

This Special Issue focuses on the role of anaerobic digestion systems for bioenergy and biofuel production and their ability to decarbonize the global energy mix. All types of original submissions that tackle key policy, economic, environmental, and technological gaps and challenges to the implementation of this technology are welcome. These topics of interest include, but are not limited to, the following:

- Mono and co-digestion feedstocks;

- Reactors used for the conversion process;

- Strategies for the optimization of anaerobic digestion key parameters;

- Main products obtained in anaerobic digestion processes and their end-users;

- The production of value-added and commercial products from anaerobic digestion residues;

- Optimization and modelling techniques;

- The life cycle assessment of anaerobic digestion systems;

- Small-scale and large-scale case and success studies;

- The legal framework of anaerobic digestion systems.

We look forward to receiving your contributions.

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. Sustainability 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 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.
