Bioremediation of Pollutants in Sewage Sludge

Dear Colleagues,

The production of sewage sludge is considered a worldwide problem due to the large volume in which it is generated due to the enormous global population. Additionally, the heterogeneity in its composition is characterized by its content of heavy metals, pathogens, organic matter, and emerging pollutants, among other hazardous compounds. The most common treatments are anaerobic or aerobic digestion (mesophilic or thermophilic), composting, or incineration. However, in the frame of the circular economy, strategies focusing on revalorization are gaining more interest, specifically in terms of converting certain residues into a potential source of nutrients; for example, in agriculture. Therefore, there is a high degree of concern about the potential pollutants that could be present in this waste and how these may be transferred to terrestrial and water ecosystems, and even reach the food chain.

Hence, this Special Issue has been launched to address the current knowledge of bioremediation strategies (bioaumgentation/biostimulation) that are focused on the degradation, transformation, mobilization, or elimination of existing pollutants in sewage sludge, including organic and inorganic compounds, with particular attention to emerging pollutants.

As guest editors of this Special Issue, we would like to invite you to submit research articles, short communications, and review articles that are aimed at this topic, with the objective of providing a collection of articles that discuss the main bioremediation strategies that can be applied to deal with the pollutants present in sewage sludge and that may become toxic or xenobiotic compounds in the environment.

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. Toxics 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 2600 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.
