“…Biomass accumulation, through the removal of nutrients present in W through the use of microalgae, was the objective of researchers such as Fan et al (2023), Paulenco et al (2023), Liu et al (2023), Zhuang et al (2023), Zuo et al (2023), , Qv et al (2023) and Muthuraman et al (2023). The microalgae species used were Chlorella sp., Nannochloris sp., Hybrid, Chlorella FACHB-30, Chlorella FACHB-5, Chlorella vulgaris, Chlorella sorokiniana and Coelastrella sp.…”

E Objective. To indicate the condition of the wastewater treatment with microalgae (WTwM) research. Methodology. The words treatment, wastewater, and microalgae, were entered as keywords in a search under "article title" in SCOPUS. The documents found were saved and exported as a file with a .bb extension. From R Studio, the BIBLIOMETRIX interface was linked to R Statistics. The interface was opened from MOZILLA to import the .bb file. Results. There is a significant increase in the number of papers published since 2013, up to 68 articles in 2022. The authors with the highest number of contributions on the subject are Ivet Ferrer and Joan García. The countries most involved in this issue are China, Spain, India and Brazil; China is the one with the highest number of publications. The WTwM studies in 2023 are concerned with investigating biomass accumulation and nutrient removal as a way to make sustainable use of the process. Conclusions. WTwM is a research topic that is studying and disseminating knowledge since the 80's. The author who stands out the most is Ivet Ferrer. China has little collaboration with scientists from other countries. The most recent WTwM studies address issues related to biodiesel production and biogas production. The topics to be addressed in future research will be related to the study of temperature, osmotic capacity, pH and O2 levels.

This paper presents a structured bibliometric analysis and review of the research publications recorded in the Web of Science database from 2000 to 2023 to methodically examine the landscape and development of the ‘wastewater to energy’ research field in relation to global trends, potential hotspots, and future research directions. The study highlights three main research themes in ‘wastewater to energy’, which are biogas production through anaerobic digestion of sewage sludge, methane generation from microbial wastewater treatment, and hydrogen production from biomass. The analysis reveals activated sludge, biochar, biomethane, biogas upgrading, hydrogen, and circular economy as key topics increasingly gaining momentum in recent research publications as well as representing potential future research directions. The findings also signify transformation to SDGs and circular economy practices, through the integration of on-site renewables and biogas upgrading for energy self-sufficiency, optimising energy recovery from wastewater treatment systems, and fostering research and innovation in ‘wastewater to energy’ supported by policy incentives. By shedding light on emerging trends, cross-cutting themes, and potential policy implications, this study contributes to informing both knowledge and practices of the ‘wastewater to energy’ research community.

Rare earth elements (lanthanides) are critical materials for many applications, particularly those involved in new energy. Extracting these elements economically from low-concentration sources may be challenging. This study investigates the interaction of Ce and Gd with microalgae that have been triggered to form phosphate-rich granules. Lanthanides usually occur in nature as phosphates, and therefore, we hypothesized that phosphate accumulation in microalgae may facilitate lanthanide sequestration. Synchrotron-based scanning transmission X-ray microspectroscopy (STXM) was used to map the distribution of Gd, Ce, and P in and around cells of Chlamydomonas reinhardtii. STXM provided X-ray absorption (XAS) spectra at the Gd M 4,5 -edge, the Ce M 4,5edge, and the P K-edge, supported by bulk X-ray absorption spectroscopy at another beamline, and elemental maps from scanning electron microscopy with energy-dispersive spectroscopy (SEM/EDS). Gd was associated with P in polyphosphate granules within C. reinhardtii and with P outside the cells. Ce was associated with P outside the microalgal cells but not with the P granules inside the cells. Gd and Ce were found to react with phosphate to form a distinct compound apparent in X-ray absorption near edge spectroscopy (XANES) of bulk samples. However, this compound is not found in the P granules that are coincident with Gd inside the alga. These differences in uptake by the microalga between Ce and Gd may suggest a selective extraction technique and could be generalized to other rare earth elements that are otherwise hard to separate.
