Special Issue Information
Dear Colleagues,
A major concern with liquid biofuels for the transportation sector is the sustainability of such fuels with respect to actual GHG reduction potential, land-use-change issues, and biomass availability. Secondly, cost competitiveness with current fossil fuels is a major barrier for the deployment of current technologies for the production of biofuels. The environmental and economic sustainability of producing liquid biofuels is largely dependent on the feedstock used for the process. Feedstocks that are easily processed into biofuels are the 1st Generation (1G) feed stocks such as oil from oil crops; sugar cane juice; and starch from cereal grains, but these feed stocks have a high price and are face challenges in the form of environmental sustainability and the food-versus-fuel dilemma. On the other hand, 2nd Generation (2G) feed stocks such as agricultural waste and municipal solid waste have a lower price, are abundantly produced, and are sustainable to use as biofuels feedstock, as they are CO2 neutral and do not compete with food production. However, conversion to biofuels is challenged by the complex composition and/or recalcitrant nature of the waste. This Special Issue will cover all aspects related to biological, thermos, and catalytic routes for the conversion of waste to fuels, focusing on current trends and technological challenges.

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. Energies 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.
