Evaluation of alternatives for microalgae oil extraction based on exergy analysis

Microalgal biofuel revisited: An informatics-based analysis of developments to date and future prospects

“…Two general extraction processes, the Hexane Soxhlet method and the BlighDyer method [55,56], are effective means of extracting microalgal lipids, with hexane-based oil extraction being more energy efficient and therefore preferred for scaling up efforts [57]. However, the disadvantages of using chemical solvents are mostly related to their high toxicity to humans and the environment.…”

Caracterización y perfil lipídico de aceites de microalgas

“…Incluso en un escenario conservador, se estima que el uso de las microalgas producirá cerca de 10 veces más biodiésel por unidad de superficie de tierra que un típico oleaginosa terrestre [1][2][3][4][5][6].…”

“…El perfil de ácidos grasos y la composición de los lípidos extraídos de una especie en particular se ve afectada por el ciclo de vida y las condiciones de cultivo, tales como la composición del medio, la temperatura, la intensidad de iluminación, la relación del ciclo de luz/oscuridad y la tasa de aireación [1,4]. Algunas especies de microalgas pueden aumentar su contenido de lípidos entre un 10 al 20% en peso durante períodos de escasez de oxígeno.…”

A review of developments in technologies and research that have had a direct measurable impact on sustainability considering the Paris agreement on climate change

“…An assessment of sustainability guidelines of the European Union (EU) RES Directive was given in [68] for the case of bio-refineries. An exergy analysis [69] was performed to evaluate the alternatives for microalgae oil extraction. In [70] third generation biofuel technologies such as algal-based biorefineries are proposed as a sustainable alternative to first generation foodbased biofuels due to 'the food-versus-fuel debate and indirect land-use change emissions'.…”
