Circularity, Sustainability, Resilience, and Analysis in Water, Wastewater, and Sludge Management

Dear Colleagues,

In recent years, circular economy and sustainability have been topics of increasing interest. This Special Issue explores innovative approaches to water, wastewater, and sludge treatment, as well as resource recovery and ecological protection. In the context of wastewater treatment, the amount of biomass waste, such as sewage sludge and organic by-products, has increased sharply in recent years, resulting in serious environmental pollution and public health concerns. Biomass waste from wastewater treatment poses a dual challenge—it is both a pollutant and a potential resource. Improper disposal of this waste can lead to soil and water contamination, greenhouse gas emissions, and increased treatment costs. Therefore, sustainable management and utilization of biomass waste are of critical importance. By adopting the principles of the circular economy, these wastes can be transformed into valuable resources, providing both environmental and economic benefits. Thus, the utilization of biomass waste is of practical importance and is in line with the goals of sustainable wastewater management. In addition, this Special Issue addresses the extremely important issue of emerging pollutants, which are of particular concern, as most of the available treatment technologies are not able to degrade them. It discusses the sources of these pollutants and their fate in the environment, as well as the main tools available for their analysis. It also describes the representative environmental panels (air, soil, and water) and the appropriate analytical methods for each panel. In addition, it reviews aspects of toxicology, chemometrics, sample preparation, and green analytical chemistry.

Authors are expected to be a part of these fields, in order to enable the development of an interdisciplinary Special Issue, in line with the characteristics of the circular economy and sustainability, which can be examined from different perspectives. We look forward to 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. Sustainable Chemistry is an international peer-reviewed open access quarterly 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 1000 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.
