From Waste to Energy: Anaerobic Digestion Technologies

Dear Colleagues,

Due to the current global energy crisis and the ambitious Net Zero emissions plans issued by various governments, it is imperative to focus on the development of new sustainable and renewable energy sources. In the last few years, the concept “Waste to Energy” (WtE) has become crucial. This is related to processes involving waste for the production of energy in the form of either heat and/or electricity and/or its transformation into a fuel source. In this context, Anaerobic Digestion (AD) is widely recognized and applied in biomass treatment, mainly in biogas production from microbial degradation. The AD technology offers versatility for implementaion in the industry sector or communities, offering benefits such as solid waste reduction, water treatment, and obtention of valuable by-products such as biogas and digestate.

However, AD still faces challenges such as feedstock availability, biomass biodegradability, management, process control and design, automatization, etc.

This Special Issue aims to present and disseminate the most recent advances in anaerobic digestion technology, including the complementing technologies that can enhance the process.

Topics of interest include (but are not limited to):

• Advances in anaerobic digestion technologies.
• Process design and technology (Advance modeling).
• Life cycle assessment.
• Novel feedstocks.
• Dark fermentation.
• Biomethane, production, treatment, storage and/or utilization.
• Bio-Hydrogen production, treatment, storage and/or utilization.
• Complementing technologies for anaerobic digestion (pretreatments and/or post-treatments).
• Bio-resource recovery (i.e., methanol, methane, VFAs, flue gases, etc.).
• Nutrient recovery.
• Digestate treatment and management.
• Microbial dynamics.

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. 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.
