“…Furthermore, compared to the cultivation of other crops, the production of microalgae requires far less fertile soil, clean water, herbicides, or pesticides; hence, it will not compete with other crops for resources [ 30 , 31 ]. It has been reported that it is possible to cultivate microalgae using wastewater sources (like those from the palm oil industry or homes with sewage systems) because different microalgal species come from other subspecies families with similar properties and characteristics beneficial for commercial applications [ 32 ].…”

Algae-based biofuel developed over the past decade has become a viable substitute for petroleum-based energy sources. Due to their high lipid accumulation rates and low carbon dioxide emissions, microalgal species are considered highly valuable feedstock for biofuel generation. This review article presented the importance of biofuel and the flaws that need to be overcome to ensure algae-based biofuels are effective for future-ready bioenergy sources. Besides, several issues related to the optimization and engineering strategies to be implemented for microalgae-based biofuel derivatives and their production were evaluated. In addition, the fundamental studies on the microalgae technology, experimental cultivation, and engineering processes involved in the development are all measures that are commendably used in the pre-treatment processes. The review article also provides a comprehensive overview of the latest findings about various algae species cultivation and biomass production. It concludes with the most recent data on environmental consequences, their relevance to global efforts to create microalgae-based biomass as effective biofuels, and the most significant threats and future possibilities.

“…Although the sizes of the circles of keywords in cluster 4 are similar, they are slightly larger in the case of microalga, in reference to a bio-treatment that is particularly attractive because of their photosynthetic capabilities, converting solar energy into useful biomasses and incorporating nutrients such as nitrogen and phosphorus, causing eutrophication [32]. This technology, in the context of biorefineries, presents several challenges, as the growth of microalgae requires large amounts of carbon, nitrogen, and phosphorus [33], thus having high harvesting, pre-treatment, and microalgal purification costs [34]. However, the use of microalgae has been shown to have significant advantages, as it reduces emissions and leads to energy savings compared to conventional processes [35].…”

Energy recovery, according to circular economy and sustainable principles, has established itself as an inevitable field of action in wastewater treatment plants (WWTPs). Energy costs are forcing the optimization of processes and increases in the development of applicable waste-to-energy (WtE) technologies. This study aims to analyze the existing knowledge on WtE research in municipal WWTPs using a systematic literature review and a bibliometric analysis from 1979 to 2021. For this purpose, Science Mapping Analysis Tool (SciMAT) and VosViewer, two softwares for analyzing performance indicators and visualizing scientific maps, were used to identify the most relevant figures in the research. The results show an exponential increase in the number of publications over time, which has yet to reach a stage of maturity. The analysis of the evolution of the topics exposes variability in the keywords over the years. The main field of WtE research has focused on sludge treatment, with technologies ranging from anaerobic digestion to more recently-emerging ones such as microalgae or membrane technologies. The analysis also identified the need for more publications on other wastes in WWTPs, which are necessary to achieve zero waste.

“…pueden desarrollar también un metabolismo heterótrofo, obteniendo la energía y el C necesarios para el crecimiento de los compuestos orgánicos presentes en el agua (materia orgánica, glucosa, galactosa, sacarosa, lactosa, etc.). Mediante cultivos de microalgas heterótrofos, es posible superar la dependencia de la luz para el crecimiento de las microalgas, consiguiendo mayores productividades de biomasa y de lípidos, haciendo que este tipo de cultivos resulten muy interesantes para la obtención de biocombustibles (Ghaffar et al, 2023). El metabolismo mixótrofo resulta de la combinación del fotoautótrofo y heterótrofo, dependiendo de la disponibilidad de sustratos y de las condiciones de luz (Ferreira et al, 2019).…”
