Preparation and Application of Biochar (Second Edition)

Dear Colleagues,

As of late, the production of sustainable biochar has received notable interest, mostly because biochar presents very versatile physicochemical properties, is easily produced with potential to use several feedstocks, and has large applicability in various fields.

Biochar is a carbon-rich and porous solid material that can be produced through the thermochemical conversion of biomass (pyrolysis, hydrothermal carbonization, gasification, torrefaction) in the presence of little or no oxygen. This material has very unique qualities, including a large surface area, calorific value, hydrophobicity, high porosity, valuable functional groups, a high cation exchange capacity, and stability. These properties have great importance for a wide variety of applications that are able to address a number of pressing ecosystem challenges: soil amendment, the remediation of environmental pollutants and wastewaters, carbon capture and storage (climate change mitigation), bioenergy, renewable gas production, metal production, catalysts (e.g., biodiesel production, tar reduction and enhanced syngas production, deNOx reactions, microbial fuel cell electrodes), and general gas cleaning. Indeed, specific end-user applications have different requirements for biochar properties, which are noticeably affected by production technology, process conditions, feedstock type, and post modifications (e.g., activation processes).

Considering the current interest and the many positive features of biochar, this Special Issue is dedicated to collecting high-quality research on biochar preparation technologies and applications, including technical, scientific, economic, and environmental topics.

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.
