Special Issue Information
Dear Colleagues,
Anaerobic digestion (AD) has long been recognized as a key technology for the sustainable management of organic wastes and the production of renewable energy in the form of biogas. However, the global transition towards the circular bioeconomy and carbon neutrality introduces new challenges and opportunities for AD systems. In this context, AD is increasingly expected to go beyond simple energy recovery and instead become a versatile biorefinery platform capable of producing a wide range of bioproducts such as organic acids, biohydrogen, biomethane, and nutrient-rich biofertilizers.
In this Special Issue, we aim to gather innovative research and comprehensive reviews addressing the latest scientific and technological advances in anaerobic digestion for bioproducts and bioenergy production. Topics of interest include, but are not limited to, the following:
- Optimization, modeling, and control of AD processes for enhanced biogas yield and stability;
- Sanitary concerns of anaerobic digestion for bioenergy production;
- Process intensification (e.g., pretreatment, DIET) and reactor design of AD systems;
- Post-treatment and energy valorisation of digestate, and integration of biogas into the circular bioeconomy
- Coupling AD with other technologies (e.g., nutriment recovery, gas upgrading and transformation, CO2 valorization, biomethanation);
- Assessment of environmental, energetic, and economic performance of AD-based systems.
We particularly welcome interdisciplinary contributions that propose novel approaches to improving the efficiency, robustness, and sustainability of anaerobic digestion, as well as contributions that explore AD’s role in the broader context of resource recovery and climate change mitigation.

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. 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.
