“…[ 48 ] Yin et al [ 49 ] also increased water collection by incorporating micro/nanopatterns to achieve a WCR of 200 mg cm −2 h −1 . Fog water harvesting is influenced by humidity conditions, [ 50 ] which is beyond the focus of this study. Higher humidity levels facilitate more efficient fog capturing capabilities due to the increased availability of water vapor for condensation.…”

Given global water scarcity and the quest for sustainable energy, there's a pressing need for integrated approaches addressing water‐energy interdependence worldwide. A practical approach for this challenge involves the implementation of fog water collectors. Herein, a polyvinylidene fluoride (PVDF) multifunctional device capable of harvesting water and electricity from wind is developed and tested, collecting up to 365 mg cm−2 h−1 of fog water. Due to the piezoelectric nature of electrospun PVDF, these yarns and meshes not only serve as piezoelectric sensors, enabling the detection of incoming fog flow and determination of its speed and, bust also harvest electricity by charging a capacitor, making it a green and renewable power source. In this study, promising insights are offered into developing efficient fog water collection methods and utilizing piezoelectric fiber‐based yarns and meshes for multifunctional applications in sustainable water management, energy harvesting, and sensing in a single device.

“…The up-flow anaerobic sludge blanket (UASB) is the most commonly used technology for the anaerobic treatment of organic wastewater (Table S8 † ). 45 The UASB reactor can be set up before the HBR to remove a portion of the COD in the FWW through anaerobic digestion. As shown in Table S9, † the organic volumetric loading rate of the UASB can be up to 2.5–13.6 kg COD per m 3 per d at 25 °C, which is much higher than that of the activated sludge or biofilm processes.…”

“…UASB is a form of an anaerobic digester that is used particularly to treat industrial wastewater and produce biogas with a high concentration of methane (Gür and Demirer 2019 ). The UASB system has a high rate of biogas production, needs low maintenance, and yields a low amount of sludge which can make it energy-self-sufficient (Ahmad and Senaidi 2023 ).…”

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.
