Potential of biofuels from algae: Comparison with fossil fuels, ethanol and biodiesel in Europe and Brazil through life cycle assessment (LCA)
Maria Luisa N.M. Carneiro,Florian Pradelle,Sergio Leal Braga,Marcos Sebastião de Paula Gomes,Ana Rosa Fonseca de Aguiar Martins,Franck Turkovics,Renata Nohra Chaar Pradelle +6 more
TL;DR: In this paper, the sustainability potential of all biofuels was evaluated by the Global Warming Potential (GWP), the Energy Ratio (ER) and the Land Use (LU), allowing a broad estimation of the bio fuels contribution to climate change mitigation, their net energy efficiency and their competiveness with food production chain.
Journal ArticleDOI
Potential of microalgal biodiesel production and its sustainability perspectives in Pakistan
Syed Hasnain Shah,Iftikhar Ahmed Raja,Muhammad Rizwan,Naim Rashid,Qaisar Mahmood,Fayyaz Ali Shah,Arshid Pervez +6 more
TL;DR: In this paper, the potential of biodiesel in Pakistan, feed stocks, biodiesel production process, barriers and future developments are discussed with research and developments goals for the promotion of biodies in Pakistan.

Recommendations for Life Cycle Assessment of algal fuels
Pierre Collet,Arnaud Hélias,Arnaud Hélias,Laurent Lardon,Jean-Philippe Steyer,Olivier Bernard +5 more
TL;DR: In this paper, a critical review focused on goal and scope, system boundaries, functional unit, Life Cycle Inventories (LCI) and environmental impacts of 41 LCA of algal biofuels is presented.
Journal ArticleDOI
A critical review on life cycle analysis of algae biodiesel: current challenges and future prospects
TL;DR: In this paper, a comprehensive and critical literature review of the LCA and sustainability assessment for the entire algal biodiesel process is presented, which can benefit relevant future studies. But, there are few comprehensive studies covering the complete process; therefore, outcomes can be inconclusive, since variability in algae type, reactor type and conditions, and other factors will impact LCA outcomes.
Journal ArticleDOI
A review of the sustainability of algal-based biorefineries: Towards an integrated assessment framework
TL;DR: In this article, a generic methodology, based on the integration of a techno-economic assessment methodology and a streamlined life cycle assessment, was proposed to evaluate the methodological reasons behind this variation.

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.

Production of first and second generation biofuels: A comprehensive review
Satya Narayan Naik,Satya Narayan Naik,Vaibhav V. Goud,Vaibhav V. Goud,Prasant Kumar Rout,Ajay K. Dalai +5 more
TL;DR: In this paper, a review of cost effective technologies and the processes to convert biomass into useful liquid bio-fuels and bioproducts, with particular focus on some biorefinery concepts based on different feedstocks aiming at the integral utilization of these feedstocks for the production of value added chemicals.

David Tilman,Robert H. Socolow,Jonathan A. Foley,Jason Hill,Eric D. Larson,Lee R. Lynd,Stephen W. Pacala,John M. Reilly,Tim Searchinger,Chris Somerville,Robert H. Williams +10 more
TL;DR: Exploiting multiple feedstocks, under new policies and accounting rules, to balance biofuel production, food security, and greenhouse-gas reduction and to accept the undesirable impacts of biofuels done wrong.

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.
