Special Issue Information

Dear Colleagues,

Biochar is a carbonaceous material with numerous applications, obtained through thermal treatment of organic materials. Its main applications include improving the physical, chemical, and biological properties of soils; remediating contaminated soils; serving as a component in growing media; and treating water. However, it should be highlighted that its use in soils has been identified as a strategy for addressing the impacts of climate change. This strategy is both mitigating, as it contributes to soil carbon sequestration, and adapting, as it can improve soil water retention by reducing the influence of changes in rainfall patterns.

In recent years, new applications of biochar have emerged, such as its use as a catalyst, as a component of more sustainable materials, in electrochemical energy storage processes, or in the preparation of more advanced environmentally friendly fertilizers within the framework of the circular economy.

Considering the above, the purpose of this Special Issue is to publish innovative research on the different uses of chars. Topics of interest include, but are not limited to, the following:

  1. Climate change mitigation and adaptation strategies.
  2. Their use in the preparation of environmentally friendly advanced fertilizers.
  3. Energy storage processes.
  4. New materials.

Articles that focus solely on their agricultural use will not be accepted, unless they are considered highly innovative studies.]

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. Environments 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 1800 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.
