Special Issue Information
Dear Colleagues,
The use of biochar for wastewater treatment, in general, and, particularly, for nutrient recovery, is a key step towards sustainability promotion and circular economy boosting. Usually, raw biochars have low nutrient recovery capacities from wastewater. For this reason, various physico-chemical modification options have been tested, including ball milling, the use of steam, acid and alkaline solutions, and metal salts-based byproducts. Recent works have shown that the success of wastewater nutrient recovery from wastewater depends not only on the biomass nature (i.e., lignocellulosic biomass, animal manure, and sewage sludge), but also on the pyrolysis conditions (i.e., pyrolysis temperature and residence time) and the adsorption settings (i.e., wastewater quality, biochar dosage, and contact time). Therefore, innovation in appropriate biochar synthesis and effective application for nutrient recovery from wastewater and in agriculture is crucial.
This Special Issue on “Biochar-Driven Nutrient Circularity in Wastewater: From Reactivity to Agronomic Reuse” welcomes high scientific level experimental works regarding the conversion of abundant biomass into effective biochar that can efficiently recover nutrients from wastewater and subsequently be used in agriculture. Topics of this Special Issue include, but are not limited to, the following:
- Raw and modified biochar synthesis and deep characterization;
- Biochar application for wastewater treatment;
- Biochar valorization for nutrient recovery from wastewater;
- Static and dynamic investigations on nutrient recovery from wastewater by tailored biochars;
- Dynamic investigations on nutrient release from the loaded biochars from wastewater.

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. Water 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 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.
