Dear Colleagues,

Worsening environmental and energy crises, due to rapid exploitation of fossil fuels, have led to an emergent need for the development of alternative energy resources. Among all alternatives, the production of bioethanol from lignocellulosic biomass particularly from agricultural residues and other waste is a viable option to mitigate the emission of greenhouse gases, impact of climate change and also reducing the loads on fossil fuels. To meet this huge demand energy researchers around the world have been searching for suitable biomass feedstocks, pretreatment methods, and appropriate microorganisms that can convert biomass into biofuels. Most importantly, there is a need for a better understanding of the inter and intramolecular changes that occur to lignocellulosic materials, during the fundamental processes of biorefining, conditioning, pretreatment, saccharification, fermentation, and purification. We are interested in the most recent advances in molecular processes that occur to biomass, during its passage through the biorefinery, using advanced instrumental analytical techniques, hypotheses, and models, validated with data from the literature, that allow the simulation and escalation of the processes. Innovative technological proposals that can eliminate the bottlenecks that interfere with lignocellulosic biofuel production specifically at the commercial level are also welcome.

The Editorial Team invites the submission of original research papers and critical review articles. Specific themes of interest include but are not limited to the following:

• Biomass feedstock: production and processing procedure.
• Inter and Intramolecular changes in the structure of biomass.
• Pre-treatment technologies (chemical and biological) for rapid biomass hydrolysis.
• Life cycle assessment of biofuel production.
• Agriculture residues and waste biomass as a source of low-cost biomass feedstock
• Optimization of process parameters using response surface methodology.
• Application of methods such as FTIR, PXRD, CLSM, SEM, TEM, and NMR to assess the degradation of biomass.

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. Sustainability 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 2400 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.
