Microalgae-based biodiesel production and its challenges and future opportunities: A review

Green Technologies and Sustainability, Год журнала: 2023, Номер 2(1), С. 100060 - 100060

Опубликована: Ноя. 1, 2023

The rapid depletion of fossil fuel reserves and rising greenhouse gas (GHGs) emissions have necessitated research into low-cost renewable energy sources, with a focus on algal-derived biofuels. Biodiesel, sustainable alternative fuel, can be derived from variety biological sources Microalgae-based biodiesel production offers an innovative method generating energy. By utilizing advanced cultivation techniques, such as photobioreactors open pond systems, microalgae grown efficiently in large quantities. Furthermore, various methods, lipid extraction transesterification, are employed to convert the lipid-rich biomass biodiesel. However, make microalgae-based more cost-effective sustainable, several challenges need addressed, higher costs, reduced productivity rates, potential environmental impacts. Future opportunities lie creating methods for cultivating harvesting microalgae, improving yields, effective conversion methods. Overall, shows promise source. further development must take place realize its full reap rewards.

Biofilm and suspension-based cultivation of microalgae to treat anaerobic digestate food effluent (ADFE)

The Science of The Total Environment, Год журнала: 2024, Номер 924, С. 171320 - 171320

Anaerobic digestion of organic waste produces effluent (ADE) that requires further treatment. Biofilm-based microalgal cultivation is a favoured approach to ADE This study compared Chlorella sp. MUR 268 and Scenedesmus 269 in biofilm suspension cultures treat anaerobic digestate food (ADFE). had significantly higher biomass (50.38 g m−2) than (9.39 m−2). Conversely, yielded 1.5 times more (1.2 L−1) suspension. 49.3 % areal productivity suspension, while showed 87.3 growth removed nutrients ADFE. In COD, ammoniacal nitrogen, phosphate were reduced 94.9, 5.2, 5.98 mg L−1 for 268, 245, 2.89, 3.22 269, respectively. biofilm, achieved reductions 149.9, 1.16, 3.57 L−1, 100.2, 6.9 2.07 L−1. Most these values are below the recommended discharge standard, highlighting efficacy this system ADFE Biofilm fixed 68–81 nitrogen was biomass, only 55–71 ended biomass. 88 phosphorus, phosphorus (55 %) counterpart (34 %). design offers advantages like simplified, cost-effective operation, easy recovery, water usage.
