Advanced Technologies in Waste-to-Bioenergy

Dear Colleagues,

The increasing global demand for sustainable energy solutions, alongside the imperative for efficient waste management, has increased academic interest in the development and implementation of advanced technological processes for waste-to-bioenergy conversion. Waste-to-bioenergy conversion technologies constitute a promising pathway towards the transition to circular economy.

This Special Issue of Energies aims to highlight the latest advancements and interdisciplinary research in waste-to-bioenergy systems, highlighting novel approaches of the efficient and sustainable valorization of various waste streams into bioenergy. Thermochemical and biochemical conversion processes will be emphasized in this field, supporting the circular economy. Studies addressing investigations into techno-economic analysis (TEA) or life cycle assessment (LCA) to evaluate the sustainability of these technologies are anticipated. Contributions exploring the characterization and valorization of diverse waste feedstocks—including municipal solid waste, agricultural residues, industrial by-products, and organic wastes—are also highly encouraged.

Furthermore, this Special Issue anticipates submissions on policy frameworks, sustainability metrics, and implementation strategies that facilitate the commercialization of waste-to-bioenergy technological schemes.

We invite high-quality submissions that include, but are not limited to, the following topics:

• Waste feedstock characterization and valorization;
• Biofuel production via variant conversion processes (e.g., pyrolysis, gasification, hydrothermal liquefaction, catalytic hydrotreatment, anaerobic digestion, fermentation, etc.) from various wastes (e.g., agricultural, municipal, industrial, and food waste and non-food energy crops, etc.);
• Bioenergy production from diverse waste streams, including agricultural, municipal, industrial by-products, food waste, and non-food energy crops;
• Techno-economic analysis (TEA) and life cycle assessment (LCA) of waste-to-bioenergy systems;
• Policy frameworks, sustainability metrics, and pathways to commercialization.

This Special Issue aims to showcase interdisciplinary approaches and breakthrough innovations that support the transition to low-carbon energy systems and sustainable waste valorization. Contributions from both academic and industrial researchers are welcome.

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. 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.
