Summary: The long-term performance of an anaerobic bioreactor combined with electrochemical oxidation and integrated into a self-contained public bathroom under daily use was investigated. The electrochemical treatment consistently generated a highly chlorinated and clear effluent that was negative to a fecal coliform assay. The system maintained its performance for disinfection and nitrogen removal under water recycling conditions, but the COD removal capacity was slightly reduced. The generation of toxic disinfection byproducts was also examined.

Summary: In this study, a novel electrochemical recycling approach for spent lead-acid batteries with ultra-low energy consumption is proposed. The co-processing of desulfurization wastewater significantly reduces the overall energy consumption of the solid-state electrolysis. The energy consumption to recycle a ton of lead is only 21.2-51.8% of the traditional electrochemical recycling process, and the desulfurization wastewater can also be effectively treated.

Summary: Agricultural biomass is an eco-friendly and effective adsorbent for the remediation of contaminants from wastewater. In this study, rice husk biochar was used for the remediation of different contaminants in real samples. The efficiency of the designed biofilter unit was assessed for the removal of different contaminants in pilot-scale experiments. The results showed that the removal efficiency varied for different metals, ranging from 5.52% to 90.76%. The designed biofilter unit could also be used for the remediation of pharmaceutical and other emerging contaminants from wastewater.

Summary: Conventional onsite wastewater treatment systems may contribute to the transmission of waterborne pathogenic microorganisms, posing a significant human health concern. Current research lacks in-depth understanding of the mechanisms for microbial contaminant removal in OWTSs, highlighting the need for further investigation into controlling processes for water quality. To optimize treatment performance, it is essential to evaluate pathogen removal effectiveness in OWTSs and explore factors contributing to efficient removal.

Summary: Controlling the spread of SARS-CoV-2 in global regions with common untreated effluent is urgent. While vaccine development is underway, timely detection and remediation of the virus in wastewater, especially in developing countries, is crucial. A proposed technique combining nanotechnology, wastewater-based epidemiology, and artificial intelligence could be effective for detecting and remedying SARS-CoV-2 in community-level wastewater.

Summary: This paper reviews and discusses state-of-the-art microbial electrochemical technologies (METs) for resource recovery from wastewater, with a focus on microbial fuel cells (MFCs), microbial electrolysis cells (MECs), and microbial recycling cells (MRCs). MRCs show the greatest potential for simultaneous nutrient recovery and efficient mineral recovery at a larger scale. METs are effective in energy conversion but face limitations and challenges. Future research should consider material lifespan, reduction of secondary pollutants, and scaled-up benchmark systems.

Summary: Household wastewater is a problem, especially in areas without wastewater collection system or treatment plant. This paper explores the possibility of using recycled shredded ABS plastic as packing media in on-site wastewater treatment plants. The studies indicate that shredded recycled ABS is a promising filtration material with important features for the treatment process. The experimental filter achieved a high reduction efficiency for BOD5, COD, and TSS in the primary effluent.

Summary: Globally, E-waste is experiencing unprecedented growth, which will be further fueled by the COVID-19 pandemic. However, governance of E-waste, particularly in the Global South, has been a complex issue. This study investigates the design, adoption, and implementation of E-waste policies in India, a major electronics manufacturing hub with a massive consumer electronics market. The study explores why India adopts seemingly inadequate and ineffective E-waste policy approaches, and attempts to identify alternative approaches.

Summary: Automation is driven by advancements in AI, robotics, sensors, and cloud computing. In Saudi Arabia, modern agricultural technology has played a crucial role in infrastructure development. Due to water shortages, irrigation is used in agricultural fields, and this study proposes a system with moisture sensors placed under trees or plants to control water flow. Remote control and monitoring can be achieved through an HTTP dashboard. A pilot test was conducted to evaluate the feasibility of an IoT-based automatic wastewater irrigation system.

Summary: The current research on sustainable plastics aims to redesign polymers with both chemical recyclability and desirable performance to replace non-recyclable petroleum-based plastics. However, optimizing contrasting properties like polymerizability/depolymerizability and recyclability/performance within a traditional monomer framework is challenging. A hybrid monomer design strategy is emerging to develop intrinsically circular polymers with tunable performance properties, by combining parent monomer pairs with contrasting or matching properties to create offspring monomers that can achieve properties beyond the limits of homopolymers or copolymers.

Summary: The uncoupled electro-peroxone system effectively treats synthetic graywater, reducing initial contaminants by up to 95% after 90 minutes of treatment, making the effluent suitable for discharge and nonpotable applications. Recycling a portion of effluent back into the system reduces water consumption and ensures continued effectiveness over multiple cycles. This two-stage system shows potential for decentralized graywater treatment in water-sensitive areas.
