Biofuel Production Using Cultivated Algae: Technologies, Economics, and Its Environmental Impacts

Energies, Journal Year: 2023, Volume and Issue: 16(3), P. 1316 - 1316

Published: Jan. 26, 2023

The process of looking for alternative energy sources is driven by the increasing demand and environmental contamination caused using fossil fuels. Recent investigations reported efficiency microalgae biofuel production due to its low cost production, high speed growth, ability grow in harsh environments. In addition, many are photosynthetic, consuming CO2 solar light biomass providing a promising bioenergy source. This review presents recent advances application production. cultivation harvesting systems factors that affect have also been discussed. Moreover, lipid extraction conversion technologies presented. mixotrophic strategy as it combines advantages heterotrophy autotrophy. Green methods such bio-coagulants flocculants reduce microalgal future, more into co-cultivation systems, new green methods, lipids optimization converting processes should be implemented increase sustainability

Techno-economic assessment of co-production of edible bioplastic and food supplements from Spirulina

Scientific Reports, Journal Year: 2023, Volume and Issue: 13(1)

Published: June 22, 2023

Large amount of plastic wastes harming the environment have raised concerns worldwide on finding alternatives to non-biodegradable plastics. Microalgae has been found as a potential source for bioplastic production, besides its more common application in pharmaceutical and nutraceutical industry. In this study, objective was techno-economically evaluate large-scale co-production Spirulina powder food supplements edible packaging. The scale production large enough satisfy 1% local (Thailand) demand (i.e., approx. 1200 MT y-1), global (approx. 1000 y-1) supplements. Results showed that revealed an attractive venture with payback time (PBT) low 2.6 y ROI high 38.5%. This because revenues generated were US$ 55.6 million y-1, despite capital (US$ 55.7 million) operating 34.9 costs. Sensitivity analysis differences profitability based variations major parameters where split ratio biomass used supplement versus bioplastic's selling price be most sensitive.

Hydrothermal liquefaction of wet microalgal biomass for biofuels and platform chemicals: advances and future prospects

Deleted Journal, Journal Year: 2024, Volume and Issue: 6(5)

Published: May 4, 2024

Abstract Recent advances in hydrothermal liquefaction (HTL) have established this biomass conversion technology as a potent tool for the effective valorization and energy densification of varied feedstocks, ranging from lignocelluloses to microalgae organic wastes. Emphasizing its application across types, exploration delves into evolving landscape HTL. Microalgae, recognized promising feedstock, offer rich source biomolecules, including lipids, carbohydrates, proteins, making them particularly attractive biofuel production. The comprehensive review explores products platform chemicals obtained through HTL microalgae, delving biodiesel production, bio-oil composition, characteristics, produce high-valued by-products. Challenges limitations, such reactor design, scalability issues, impact microalgal composition on yields, are critically analyzed. future prospects research directions section envision advancements technology, integration with biorefinery processes, hybrid approaches enhanced Overall, paper emphasizes potential wet underscores need continued overcome existing challenges unlock further opportunities sustainable chemical
