Topic Information

Dear Colleagues,

This Topic invites research on advanced anaerobic digestion (AD) for high-strength wastes (e.g., agro-industrial effluents, livestock manure, food processing residues), with an emphasis on additive-enhanced systems. The use of biochar, nano-zero-valent iron, and magnetic nanocomposites has shown the potential to boost methane yields by enhancing microbial syntrophic interactions, electron transfer, and process resilience. Authors are encouraged to include comparisons with conventional AD setups and to report key performance indicators such as methane production, organic matter removal (COD/VFA), biogas composition, and reactor stability. Studies exploring digestate post-treatment, recovery of nutrients or other by-products, and microbiological enhancements are also welcome. Biogas upgrading to biomethane—via pressure swing adsorption (PSA), water scrubbing, amine absorption, or membrane technologies—is appreciated, particularly when integrated with AD configurations such as high-pressure digestion. This Topic promotes hybrid systems that couple AD with processes like hydrothermal carbonization, composting, membrane filtration, biotransformation, or constructed wetlands to improve energy recovery, nutrient cycling, and overall sustainability. Contributions are welcome that address environmental and operational advantages, as well as implications for circular bioeconomy models. Comparative assessments, novel reactor designs, and performance improvements will help illustrate efficient and scalable pathways for AD-based valorization of concentrated organic waste streams.

Preprints.org is a multidisciplinary platform offering a preprint service designed to facilitate the early sharing of your research. It supports and empowers your research journey from the very beginning.

MDPI Topics is collaborating with Preprints.org and has established a direct connection between MDPI journals and the platform. Authors are encouraged to take advantage of this opportunity by posting their preprints at Preprints.org prior to publication:

  1. Share your research immediately: disseminate your ideas prior to publication and establish priority for your work.
  2. Safeguard your intellectual contribution: Protect your ideas with a time-stamped preprint that serves as proof of your research timeline.
  3. Boost visibility and impact: Increase the reach and influence of your research by making it accessible to a global audience.
  4. Gain early feedback: Receive valuable input and insights from peers before submitting to a journal.
  5. Ensure broad indexing: Web of Science (Preprint Citation Index), Google Scholar, Crossref, SHARE, PrePubMed, Scilit and Europe PMC.
