“…GC profiles showed that saturated fatty acids (SFAs) were over 90% of total FAME, in T. obliquus and D. abundans grown in BBM-N/L 120 and BBM+N/L 200 , respectively. The ideal FAME component for good quality biodiesel should be rich in palmitic (C16:0) and stearic acids (C18:0): a high percentage of saturated FAME favors better viscosity (flow properties) and the applicability of biodiesel at low temperatures [ 27 ]. In this study, C16:0 and C18:0 were detected in all culture conditions in both strains, with a percentage of up to 81% for C16:0 and 15% for C18:0.…”

The development of clean and renewable energy sources is currently one of the most important challenges facing the world. Although research interests in algae-based energy have been increasing in the last decade, only a small percentage of the bewildering diversity exhibited by microalgae has been investigated for biodiesel production. In this work, seven strains of green microalgae belonging to the genera Scenedesmus, Tetradesmus and Desmodesmus were grown in liquid medium with or without a nitrogen (N) source—at two different irradiances (120 ± 20 and 200 ± 20 μmol photons m−2 s−1)—to evaluate biomass production and FAME (fatty acid methyl esters) content for biodiesel production. The strains of Tetradesmus obliquus and Desmodesmus abundans grown in N-deprived medium showed the highest FAME content (22.0% and 34.6%, respectively); lipid profile characterization highlighted the abundance of saturated FAME (as C16:0 and C18:0) that favors better viscosity (flow properties) and applicability of biodiesel at low temperatures. Light microscopy and confocal laser scanning microscopy observations were employed as a fast method to monitor the vital status of cells and lipid droplet accumulation after Nile red staining in different culture conditions.

Microalgae have garnered significant interest among researchers and industries as a potential source of valuable products that can find applications in the food, feed, biofuels, cosmetics, pharmaceuticals, and nutraceuticals industries. Microalgae can remediate various waste streams. This review discusses the current trends in the valorization of algal biomass and proposes integrated biorefinery approaches to produce high‐value products by sustainable routes. In such processes, the waste streams can be used as a source of nutrients for the production of microalgal biomass, rich in high‐quality lipids, digestible proteins and bioactive compounds. The integrated approaches presented in this study offer cost‐effective and environment‐friendly processing techniques while expanding the bioproducts portfolio in the food and therapeutics sector. The simultaneous or sequential extraction of valuable compounds from microalgae makes the biorefinery proposition appealing for waste minimization, revenue diversification, and complete feedstock utilization. The systematic exploration of microalgae on a large scale is required to evaluate its future as a favorable resource for biorefinery products. This would also necessitate detailed techno‐economic, environmental, and lifecycle assessment for the biorefinery processes. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd

“…CCU by mineral carbonation technology, also called CO 2 mineralization, is a less explored method of sequestering CO 2 compared to other CCS methods, such as geological sequestration [10][11][12], ocean disposal [13][14][15], and biological fixation [16][17][18]. Mineral carbonation involves the chemical conversion of CO 2 to solid inorganic carbonates permanently fixing carbon with a negligible risk of return to the atmosphere without having a great impact on the surrounding environment and ecosystems [19,20].…”

Based on the operating data of a 40 tCO2/day (2 megawatt (MW)) class carbon capture and utilization (CCU) pilot plant, the scaled-up 400 tCO2/day (20 MW) class CCU plant at 500 MW power plant was economically analyzed by applying the levelized cost of energy analysis (LCOE) and CO2 avoided cost. This study shows that the LCOE and CO2 avoided cost for 400 tCO2/day class CCU plant of mineral carbonation technology were 26 USD/MWh and 64 USD/tCO2, representing low LCOE and CO2 avoided cost, compared to other carbon capture and storage CCS and CCU plants. Based on the results of this study, the LCOE and CO2 avoided cost may become lower by the economy of scale, even if the CO2 treatment capacity of the CCU plant could be extended as much as for similar businesses. Therefore, the CCU technology by mineral carbonation has an economic advantage in energy penalty, power plant construction, and operating cost over other CCS and CCU with other technology.
