Summary: This research introduces a digital twin method to simulate the coordinated operation of energy flexibility resources in wastewater resource recovery facilities. Results show a reduction in electricity bills of 17% and an annualized return on investment of 3% in a California facility. However, new energy flexibility investments are less profitable without time-of-use incentives and existing cogeneration facilities. Overall, the findings suggest the need for policies and subsidies to incentivize the sector's energy flexibility. Rating: 8/10.

Summary: This study investigated the variation of water quality parameters and antibiotics in rivers inflowing into Taihu Lake. The results showed that the concentration of pollutants varied between seasons, and antibiotics were detected in both surface waters and sediments. Antibiotics in surface waters were mainly related to temperature, dissolved oxygen, total nitrogen, and ammonia nitrogen, while antibiotics in sediments were mainly related to temperature, pH, and total nitrogen. The concentrations of antibiotics were higher in winter, and the ecological risk values of antibiotics were also higher in winter compared to other seasons.

Summary: Wastewater treatment plants are complex systems that require monitoring using sensor systems. Soft sensor models can be a cost-effective alternative to expensive sensors for certain parameters in wastewater. This paper proposes a hybrid neural network architecture for learning soft sensors for complex phenomena, and validates the effectiveness using real-world data from a wastewater treatment plant. Additionally, a annotated dataset of a secondary wastewater treatment plant is publicly released to accelerate research in the development of soft sensors.

Summary: Water scarcity is a major challenge, especially in climate change-affected regions like the Mediterranean basin. Promoting safe water reuse is crucial to meet future water demands sustainably and alleviate water stress. However, limited incentives, social trust, and governance complexity hinder the adoption of water reuse practices. Structural changes, including transforming wastewater treatment plants into reclaimed water facilities, and paradigm shifts in social, political, and legal factors are needed. This manuscript provides a comprehensive analysis of Italy's wastewater treatment sector and offers recommendations for wastewater reuse in agriculture, along with data on water reuse technologies. It aims to align technical, economic, legal, and socio-political perspectives to overcome barriers and promote water reuse development.

Summary: Due to its simple process, environmental friendliness, and low operating costs, biometallurgy has become a popular technology for metals recovering from low-grade ores and tailings. An optimized agar was used to isolate and grow functional bacteria, resulting in the successful isolation of six functional stains. These strains were further tested for their ability to leach metals from polymetallic sulfide tailings, with significant improvements observed when the strains were mixed together. The selection of leaching process should be based on tailings composition and target metals.

Summary: This study examines the association between urban Green and blue spaces (GBS) exposure and Emotion and behavior problems (EBP) in youth populations. The findings suggest that higher exposure to GBS, particularly green spaces (GS) and blue spaces (BS), is associated with a decrease in the risk of developing total difficulties in young individuals. The joint effect of GS and BS may also contribute to the decrease in EBPs.

Summary: The present study investigated the sustainable approach for wastewater treatment using waste algal blooms. The biochar produced by the marine algae Ulva reticulata was used to remove chromium, nickel, and zinc from aqueous solutions. The study examined the adsorbents' properties and stability using SEM/EDX, FTIR, and XRD. The results showed that the biochar had high removal efficiency for the toxic metals, and the packed bed column effectively removed the heavy metal ions. The Thomas and Adams-Bohart models were found to best fit the regression values, and desorption studies were conducted to understand the sorption and elution processes.
