Algae Based Bio-Renewable Energy for Sustainability

Dear Colleagues,

This Special Issue seeks submissions that aim to make algal biofuels sustainable and economically viable. To this end, inputs, such as water and nutrients, must be recycled and obtained from waste resources, such as wastewater and flue gas. When recycling water, algal growth inhibitors need to be removed. Membrane filtration is one method to remove inhibitors. Current open pond systems take up a lot of land, use a lot of water, and are susceptible to contamination and predation. Thus, efforts are needed that increase areal productivity, such as biofilm systems or vertically oriented photobioreactors. Biofilm systems innately use much less water than open ponds, which aid in harvesting and dewatering. Furthermore, they may be less susceptible to contamination. Crop protection strategies are needed to move open pond technology forward. In addition, novel harvesting and cost-effective technologies need to be developed for concentrating algal biomass and extraction of lipid from the algal biomass, respectively. At last, a system level analysis is needed to evaluate the economic feasibility of the biofuels production including LCA (life cycle analysis) and techno economic analysis.

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 250 words) can be sent to the Editorial Office for assessment.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.
