Special Issue Information
The increasing volume of industrial, agricultural, and municipal waste presents significant environmental challenges. However, the utilization of these wastes to recover valuable materials provides a sustainable solution to climate change and resource scarcity. Various biochemical and thermo-chemical conversion technologies are utilized to transform diverse waste streams into value-added products such as biofuels, biochemicals, biochar, and renewable energy. These waste-to-energy pathways significantly reduce landfill dependency and mitigate greenhouse gas emissions.
Biochemical processes include anaerobic digestion, fermentation, dark fermentation, and composting, while thermochemical processes encompass gasification, pyrolysis, and hydrothermal operations. Currently, researchers are interested in hybrid systems that synergistically combine bio- and thermo-chemical processes to enhance overall efficiency. Despite their potential, there are challenges in the utilization of these processes, such as feedstock variability and contamination, economic viability, process efficiency, and market demand for circular products.
This Special Issue focuses on recent advances in the development and application of different hybrid systems, combining biochemical and thermo-chemical conversion to enhance overall efficiency and create high-value products.

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.
