TLDR
This work proposes the use of biofuels derived from aquatic microbial oxygenic photoautotrophs, more commonly known as cyanobacteria, algae, and diatoms, to mitigate some of the potentially deleterious environmental and agricultural consequences associated with current land-based-biofuel feedstocks.About:

Biofuels from microalgae—A review of technologies for production, processing, and extractions of biofuels and co-products
TL;DR: In this article, the authors reviewed the technologies underpinning microalgae-to-bio-fuels systems, focusing on the biomass production, harvesting, conversion technologies, and the extraction of useful co-products.
Journal ArticleDOI
The potential of sustainable algal biofuel production using wastewater resources
TL;DR: The current research on this topic is reviewed and the potential benefits and limitations of using wastewaters as resources for cost-effective microalgal biofuel production are discussed.
Journal ArticleDOI
Genetic Engineering of Algae for Enhanced Biofuel Production
TL;DR: Potential avenues of genetic engineering that may be undertaken in order to improve microalgae as a biofuel platform for the production of biohydrogen, starch-derived alcohols, diesel fuel surrogates, and/or alkanes are focused on.
Journal ArticleDOI
Biomass pyrolysis kinetics: A comparative critical review with relevant agricultural residue case studies
TL;DR: A critical review of kinetic models and mathematical approximations currently employed in solid state thermal analysis is provided and analysis of thermal decomposition data obtained from two agricultural residues, nutshells and sugarcane bagasse reveals the inherent difficulty and risks involved in modeling heterogeneous reaction systems.
Journal ArticleDOI

Use of U.S. Croplands for Biofuels Increases Greenhouse Gases Through Emissions from Land-Use Change
Tim Searchinger,Ralph E. Heimlich,Richard A. Houghton,Fengxia Dong,Amani Elobeid,Jacinto F. Fabiosa,Simla Tokgoz,Dermot J. Hayes,Tun-Hsiang Yu +8 more
TL;DR: This article found that corn-based ethanol, instead of producing a 20% savings, nearly doubled greenhouse emissions over 30 years and increased greenhouse gases for 167 years, by using a worldwide agricultural model to estimate emissions from land-use change.
Journal ArticleDOI
Land Clearing and the Biofuel Carbon Debt
TL;DR: Converting rainforests, peatlands, savannas, or grasslands to produce food crop–based biofuels in Brazil, Southeast Asia, and the United States creates a “biofuel carbon debt” by releasing 17 to 420 times more CO2 than the annual greenhouse gas reductions that these biofuel reductions would provide by displacing fossil fuels.
