Dear Colleagues,

Biomass is defined as “The biodegradable fraction of products, waste and residues from biological origin from agriculture (including vegetal and animal substances), forestry and related industries, fisheries and aquaculture, as well as the biodegradable fraction of industrial and municipal waste” by the European Directive 2009/28/EC. From a bioenergy perspective, biomass may be broadly defined as the organic matter derived from plants, which includes wood, bark, and energy crops, as well as wastes, and algae.

Recently, biomass conversion has received considerable interest due to economic and environmental concerns related to the utilization of depleting petroleum reserves. The utilization of underused or unused biomass in a biorefinery scheme seems to be an economically attractive and sustainable process to reduce waste and to produce value-added materials, chemicals, or fuels from biomass. 

Thermochemical treatments are among the most important conversion methods of biomass in addition to extraction. Thermochemical treatments of biomass include torrefaction, low-temperature, moderate-temperature, and high-temperature pyrolysis, gasification, hydrothermal carbonization (HTC), and liquefaction (HTL), as well as direct liquefaction (solvolysis).

This Special Issue aims to analyze recent advances in different thermochemical treatments of biomass to lay the groundwork for future studies. The submitted articles should comply with The United Nations Sustainable Development Goals (SDGs) and green chemistry principles.

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.
