“…Wet solvent extraction of lipid from microalgae biomass which eliminates the need for drying and potentially reducing energy input may be possible, but has yet to be proven at industrial scale (de Boer et al 2012;Lardon et al 2009;Sills et al 2012); but for microalgal biofuels to yield net gains in energy lipid extraction methods for wet biomass must be developed (Sills et al 2012;Delrue et al 2012). …”

“…The partial extraction of energy from the microalgae in the form of biodiesel does not appear to be energetically or commercially viable on its own and anaerobic digestion appears vital to any efficient and economic process for producing biodiesel from microalgae (Milledge 2010a;Stephenson et al 2010;Zamalloa et al 2011;Delrue et al 2012). One study has suggested that when the lipid content is below 40 % the anaerobic digestion of the entire biomass without lipid extraction may be the optimal strategy for energy recovery ).…”

“…Revisiting algae biofuels 3.1 Algae technical specificities Several studies have been conducted on the technical feasibility of growing algae for biofuel production in the laboratory (Williams and Laurens, 2010;Demirbas and Demirbas, 2010;Tao and Aden, 2009;Chisti, 2007;Brennan and Owende, 2010;Hirano et al, 1997;Ono and Cuello, 2006;Pulz, 2001;Pulz and Gross, 2004;Sheehan et al, 1998;Spolaore et al, 2006;Terry and Raymond, 1985;Ugwu et al, 2008;Delrue et al, 2012;Wijffels and Barbosa, 2010), which have proved absence of the major drawbacks associated with current biofuels. However, several hurdles still need to be overcome in order to scale up the production, while the costs of producing this emerging biofuels are still high compared with other biofuel sources.…”

“…The Net Energy Ratio of algae biofuels normally performs poorly when compared to petrol fuels, although some innovative processes claim they can improve it greatly, it still is an area of vast debate (Batan et al, 2010;Lardon et al, 2009;Frank et al, 2012;Sander and Murthy, 2010;Delrue et al, 2012Delrue et al, , 2013.…”

Purpose -Currently, experimental and theoretical work is being performed to ensure that biofuels from microalgae become a reality. However, there is a considerable number of discussions concerning in which processes should be focussed efforts of research and development. The purpose of this paper is to provide decision support not only to help build guidelines of research to be undertaken, but also to contribute to the design of more adequate policy and funding instruments. The key objective of this study is to determine the prospects of employing microalgae into the production of biofuels within a time scale extending to 2030. Design/methodology/approach -The Delphi method is a qualitative research aiming to support strategic future-oriented action, such as policy making in the areas of science and technology. It is especially appropriate in judgment and long-range forecasting (20-30 years) situations, when expert opinions are often the only source of information available, due to a lack of appropriate historical, economic or technical data. Findings -The Delphi method proved to be a successful research method when expert opinions are the main source of information available, due to a lack of appropriate historical, economic or technical data and the outcomes provided a clear outline of the main issues of microalgae biofuels' market at present and in the future.Research limitations/implications -The outcomes might not represent the majority of the microalgae experts' opinion due to the sample size. Originality/value -The work presented in this paper is especially original. According to the authors' knowledge, this is the first qualitative Delphi study related to algae biofuels.

“…Many parameters can influence the sustainability and economic performance of growing microalgae for biodiesel and biomass, in particular: cultivation area, lipid content and productivity, biomass productivity, efficiency of the process units and selling prices of the microalgae oil and extracted biomass (Campbell et al, 2011;Pfromm et al, 2011;Delrue et al, 2012).…”

a b s t r a c tThis article evaluates the sustainability and economic potential of microalgae grown in brewery wastewater for biodiesel and biomass production. Three sustainability and two economic indicators were considered in the evaluation within a life cycle perspective. For the production system the most efficient process units were selected. Results show that harvesting and oil separation are the main process bottlenecks. Microalgae with higher lipid content and productivity are desirable for biodiesel production, although comparable to other biofuel's feedstock concerning sustainability. However, improvements are still needed to reach the performance level of fossil diesel. Profitability reaches a limit for larger cultivation areas, being higher when extracted biomass is sold together with microalgae oil, in which case the influence of lipid content and areal productivity is smaller. The values of oil and/or biomass prices calculated to ensure that the process is economically sound are still very high compared with other fuel options, especially biodiesel.
