Special Issue Information

Dear Colleagues,

Wastewater is no longer viewed as waste but rather as a source of valuable resources, including clean water, renewable energy and nutrients. Reuse of wastewater for landscape and crop irrigation and indeed for domestic consumption is a widely accepted and growing practice to save water where water is in limited supply. Energy can be extracted from the organic matters in wastewater during anaerobic treatment to produce biogas, e.g., methane and hydrogen gases. Nutrients such as nitrogen and phosphorus in wastewater can also be recovered to produce fertilizers for sustainable agriculture production. Development of technologies such as complete anaerobic wastewater treatment technologies has the potential to achieve net energy production and resource recovery while meeting stringent effluent standards.

This Special Issue is focused on all the technologies that can be capable of resource recovery from any kind of wastewater sources. Special emphasis is devoted to the process control, optimatization, and development of novel anaerobic technologies for wastewater treatment and resource recovery from industry and municipal wastewater. We welcome contributions related, but not limited, to the following environmental research topics:

  • Theories, models, and technologies for anaerobic wastewater treatment;
  • Various high-value resources recovery from industrial and agricultural waste streams;
  • Environmental materials for resources enrichment and recovery;
  • Biogas production during anaerobic treatment process;
  • Heat recovery from a wastewater treatment process;
  • Wastewater reuse for argriculture irrgation.

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. Fermentation is an international peer-reviewed open access monthly journal published by MDPI.

Anaerobic digestion is a potential treatment for industrial wastewater that provides valuable end-products, including renewable energy (biogas). However, waste streams may be too variable, too dilute at high volumes, or missing key components for stable digestion; all factors that increase costs and operational difficulty, making optimisation crucial. Anaerobic digestion may benefit from process intensification, particularly the novel combination of high-strength source-separated wastewater to minimise volume, together with the use of biosolids biochar as a chemical and microbial stabiliser. This study investigates the stability, yield, and microbial community dynamics of the anaerobic digestion of source-separated industrial wastewater from a food manufacturer and a logistics company, using biosolids biochar as an additive, focusing on gas and volatile fatty acid (VFA) production, process stability, and the microbial community using bench-scale semi-continuous reactors at 30- and 45-day hydraulic retention time (HRT). While gas yields were lower than expected, stability was possible at high HRT. Methane production reached 0.24 and 0.43 L day−1 per litre reactor working volume at 30- and 45-day HRT, respectively, despite high VFA concentration, and was linked to the relative abundance of Methanosarcina in the microbial community. Interactions between substrate, VFA concentration, and the microbial community were observed. Biochar-assisted anaerobic digestion holds promise for the treatment of source-separated wastewater.
