Marketing the coproducts generated (i.e., postextraction algal residue) could make transportation fuel from microalgae a viable product. The biofuel obtained from microalgae is qualitatively and quantitatively analyzed, with a focus on the energetic and environmental feasibility of this fuel for use in the transportation sector. Obstacles to and limitations of the process, in terms of energy and environmental performance, are identified. An important aspect of this issue is the need to improve product processing and recovery, which include mechanical and energy-intensive processes such as centrifugation, filtration, flocculation, and cell disruption. Results obtained so far indicate that the various strains of microalgae obtained from lagoons in Portugal and Spain offer a huge prospect for biodiesel production. However, results of life-cycle analysis with the Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation model (updated with Portuguese data) lead to the conclusion that, at this stage, biodiesel from microalgae is not a valid option for the large-scale replacement of conventional fuels. Specifically, the extraction step for biodiesel production is detrimental in terms of energy and solvent use and must be refined. <\/jats:p>","DOI":"10.3141\/2385-02","type":"journal-article","created":{"date-parts":[[2014,1,28]],"date-time":"2014-01-28T02:03:47Z","timestamp":1390874627000},"page":"11-18","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Biodiesel from Lagoon Microalgae"],"prefix":"10.1177","volume":"2385","author":[{"given":"Margarida C.","family":"Coelho","sequence":"first","affiliation":[{"name":"Center for Mechanical Technology and Automation, Department of Mechanical Engineering, University of Aveiro, Campus Universit\u00e1rio de Santiago, 3810-193 Aveiro, Portugal."}]},{"given":"Smritikana","family":"Dutta","sequence":"additional","affiliation":[{"name":"Center for Mechanical Technology and Automation, Department of Mechanical Engineering, University of Aveiro, Campus Universit\u00e1rio de Santiago, 3810-193 Aveiro, Portugal."}]},{"given":"Fernando Neto","family":"da Silva","sequence":"additional","affiliation":[{"name":"Center for Mechanical Technology and Automation, Department of Mechanical Engineering, University of Aveiro, Campus Universit\u00e1rio de Santiago, 3810-193 Aveiro, Portugal."}]}],"member":"179","published-online":{"date-parts":[[2013,1,1]]},"reference":[{"key":"bibr1-2385-02","unstructured":"BenemannJ.
