Special Issue Information

Dear Colleagues,

In a critical context, circular economies are crucial to find new sources of energy and raw materials. Anaerobic digestion of waste biomasses (i.e., organic fractions of municipal solid wastes, sewage sludge, agro-industrial residues) may represent a valuable strategy to recover energy (biogas) and raw materials (anaerobic digestate to be used as fertilizer), while at the same time disposing of these materials in a more sustainable way, avoiding environmental pollution.

In this context, the aim of this Special Issue is to collect valuable scientific contributions in terms of research articles and review articles which aim to provide cutting-edge information related to anaerobic digestion. Studies dealing with new waste biomass streams (i.e., bioplastics), innovative pretreatments to enhance biogas production, optimization of established processes, fates of inorganic/organic pollutants, and digestate valorization and reuse will be welcomed. The submission of studies dealing with economic, social, and environmental sustainability of anaerobic digestion is encouraged.

A list of suggested themes for submission is given below:

  • Anaerobic digestion in the circular economy framework: legal, social, and economic assessments;
  • New waste biomass streams characterization (i.e., availability, chemical characterization, pretreatments);
  • Pretreatments to enhance biogas production (i.e., new pretreatments, economic assessment of pretreatments);
  • Anaerobic digestion optimization (i.e., co-digestion, technological advances);
  • Occurrence, transformation, and fate of organic pollutants in anaerobic digestion;
  • Occurrence, transformation, and fate of inorganic pollutants in anaerobic digestion;
  • From biogas to biomethane;
  • Anaerobic digestate management and processing;
  • Anaerobic digestate as source of nutrients in agriculture;
  • Anaerobic digestate as source of added value products (i.e., chemicals, biostimulants, growing medium for microalgae, insects, etc.);
  • Economic sustainability of anaerobic digestion;
  • Environmental impact of anaerobic digestion.

We look forward to receiving your contributions.

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. Sustainability 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 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.

The global food system is and will be facing many challenges in the coming decades, which will necessitate innovative solutions to address the issues of a diminishing fertilizer supply, an increasing food demand from growing populations, and frequent extreme climates due to greenhouse gas emissions. An advancement proposed is the synthesizing of fertilizer from food waste, here referred to as food waste anaerobic digestate (FWAD). This occurs through the process of anaerobic digestion, where organic matter such as food waste is contained in an anaerobic environment and allowed to be broken down by microorganisms. One of the resulting products is anaerobic digestate, which possesses the necessary nutrients for effective fertilization for crop production. In addition to reducing greenhouse gases and waste in landfills, the replacement of synthetic fertilizers with ones made from food waste would help to alleviate the impacts of the current fertilizer shortage being experienced worldwide, which will be exacerbated by a reducing supply of materials needed for synthetic fertilizer production. In this paper, we discuss the nutrient characteristics of FWAD, and recent studies utilizing FWAD in horticulture and crop production, to advance our understanding of the effectiveness and challenges of using FWAD as a fertilizer. By employing appropriate application methods, such as nitrification, dilution, and amendment, FWAD demonstrates considerable potential as an effective fertilizer for a wide range of leafy greens and some fruiting crops.
