The spatially differentiated environmental impacts and associated costs of technological improvement and circular agricultural practices in sugarcane production were assessed. Analysis of the cause-effect relationship between the key processes and substances each helped develop alternative scenarios for impact reduction. PM 2.5 emissions contributed to 92 % of the total human health impacts from open burning of field residues. Freshwater ecotoxicity, mainly due to ametryn emissions from pesticide application, contributed to 47 % of the total damage to the ecosystem. The environmental costs were 116 % higher than the value of sugarcane production, signifying the critical importance of adopting alternative pathways that provide economic benefits from environmental cost reduction compared to the production value. Scenarios considering green cane harvesting and waste management approaches demonstrated high potential for total impact reduction of 99 % and 97 %, respectively, and economic gains of 202 and 225 billion THB, respectively (5.76 and 6.42 billion USD, respectively). The economic benefits of waste utilization were 137 % higher than the value of sugarcane production, demonstrating the potential benefits of product substitution to help mitigate impacts. The core findings highlight the significance of the PM 2.5 impact-related external costs and underscore the benefits of adopting green cane harvesting in conjunction with on-field waste utilization to mitigate the impact of open burning and produce value-added products. Technological improvement and circular agricultural practices coupled with valuation of spatially differentiated impacts can provide useful and more accurate information to policymakers, to prioritize the implementation of mitigation strategies for enhancing the environmental sustainability of sugarcane production.

Landfills are unique terrestrial ecosystems with some specific traits, such as extremely high heterogeneity, drastic exhaustion and accumulative stress from various toxic contaminants along with depth/age. However, the microbial community structure of this unique ecosystem is poorly understood. Here, we examined the microbial communities along with landfill depth and age (LDA) in a sanitary landfill in Beijing, China using 16s rRNA Illumina sequencing and GeoChip 4.6. Surprisingly, in contrast with the decreased microbial diversity along with depth in soil, we found that both phylogenetic and functional diversities were higher in deeper and older refuse in the landfill. Phylogenetic compositions were obviously different in the refuse with the same LDA and such difference is mainly attributed to the heterogeneity of refuse instead of random process. Nevertheless, functional structures were similar within the same LDA, indicating that microbial community assembly in the landfill may be better reflected by functional genes rather than phylogenetic identity. Dissimilarity test showed significantly different functional structures along with LDA. Higher abundance of stress response genes, organic remediation genes, and metal resistance genes in deeper and older refuse indicated that they may be required by microorganisms in response to the more stressful environments;and their significantly positive correlations with functional diversity implied that stress was an important factor influencing functional diversity. This study not only provides guidance for acceleration of landfill stabilization and in situ remediation, but also suggests a potential of landfill as the model ecosystem to investigate the response of microbial community to tolerable stress. © 2025, The Authors.

Recently, the Massachusetts Department of environmental Quality engineering (DEQE) completed a study of the groundwater pollution potential of liquid waste impoundments. Known as the Surface Impoundments Assessments (SIA), this project was part of a federally funded examination of the widespread practice of storing waste materials in pits, ponds, and lagoons. It was conducted in all States and Territories of the United States through the auspices of the U. S. environmental Protection Agency (EPA) under the authority of the Safe Drinking water Act. In most states, Massachusetts among them, this was the first systematic review of the practice. This Assessment has also served as a catalyst to focus attention upon the systematic and coordinated protection of groundwater. The Division of Hazardous Wastes, responsible for individual site inspection and regulation, has devised a program of central and regional State staff, and local volunteer agent cooperation in the municipalities. This program may provide a useful model for efficient use of technical staff time when an agency is suddenly confronted by a large number of potential problems and a short time for review before necessary effective action.

This study proposes a new approach, a communal-based domestic rainwater harvesting (CDRWH) system, which is a new model that combines domestic and communal rainwater harvesting systems. This model is an alternative solution to improve system performance and utilize rainwater overflow from the system. Rainwater runoff from several domestic tanks is channeled to a communal tank to be collected, processed, and redistributed to needy domestic tanks. Overflow from the communal tank is used for groundwater recharge. The CDRWH system model aims to increase water supply, reduce runoff, and conserve groundwater. The model simulation uses daily water balance analysis and yield before spillage algorithm. The simulation scenario uses variations in roof area, number of house occupants, storage tank volume, and rainfall categories: 20 years, wet year, normal year, and dry year. Jagakarsa, an urban area in South Jakarta, was selected for the CDRWH system modeling. The results showed that the CDRWH model significantly improved the performance of the volumetric reliability (VR) and time reliability (TR) systems. In addition, the model could show a comparison of total groundwater recharge (GWR) and groundwater extraction (GWE), where the GWR capacity was higher. This allows centralized rainwater management in communal tanks, thereby reducing groundwater usage. The design of this model is simple. Therefore it can be easily duplicated for application in other locations. © 2025 The Authors

Floating photovoltaic (FPV) systems are designed for free water surface installations to provide a feasible solution for places with no availability of land areas and to avoid land-use conflicts caused by conventional solar energy farms. However, lakes and reservoirs are essential for ecosystem services like water supply and biodiversity support. In this regard, there was a lack of long-term and high-frequency monitoring data of important parameters influenced by FPV installation such as photosynthetically active radiation (PAR) and dissolved oxygen (DO). Temperature, despite being more reported, there is no consensus on increase or decrease values below the FPV. In this study, we conduct a comprehensive field assessment to accurately quantify temperature variations (at the weather station, modules, between the modules and the water surface and within the water), DO, and PAR of a FPV installed in a water supply reservoir. High-frequency monitoring sensors indicated that despite the 94.7% of radiation reduction below the FPV compared to the lake reference station, slight differences in water temperature and dissolved oxygen were found between measurements in monthly and daily averages in a system that covers less than 1% of the reservoir water surface. In addition, a microclimate due to the module warming is created between the module and water surface with temperature 12% greater than the weather station measurements. The fluctuation throughout the different time frequencies showed that the processes of the reservoirs are influenced by the FPV according to complex interactions among meteorological conditions, FPV configuration, and site-specific factors.

The curve number method for estimating rainfall runoff has continually evolved since its creation in the mid-20th century. Because it is inherently an empirical model that is broadly applied to many hydrological applications, the rationales for its parameters have become removed from physical interpretation over its evolution. The ASCE EWRI CN-Hydrology Committee, i.e., some of the foremost experts on this methodology, often finds itself internally at odds regarding many aspects of CN-hydrology. Here, the committee has synthesized its member's perspectives on the physical interpretations of one CN-method parameter, the initial abstraction (Ia). This note provides insights into how the Ia concept has evolved and offers some context into reasons behind its evolution. This note also synthesized different interpretations of Ia within the framework of different hydrological settings, applications, and spatial scales. Broadly speaking, the committee suggests that Ia might need to be interpreted on a case-by-case basis although this note places reasonable boundaries on Ia for most applications. © 2025 American Society of Civil Engineers.

A sustainable approach for selective ammonium recovery from wastewater: synergy of microbial fuel cell and battery deionization

引用

Desalination 2025年 613卷

作者： Po-Yen Wang Shao-Wei Tsai Cuijie Feng Chia-Hung Hou Graduate Institute of Environmental Engineering National Taiwan University Taipei 10617 Taiwan Center for Water Resources and Environment School of Civil Engineering Sun Yat-sen University Guangzhou 510275 China Southern Marine Science and Engineering Guangdong Laboratory (Zhuhai) Zhuhai 519082 China

The approach to sewage treatment is evolving from conventional pollutant removal methods to adopting a circular economy that focuses on energy and resource recovery. Ammonium ions (NH 4 + ) serve as a crucial industrial resource but also contribute to environmental pollution, particularly in sewage, leading to various ecological issues. Therefore, the development of an NH 4 + selective recovery technology with low energy consumption is imperative. In this study, we present a novel approach called MFC-BDI, which combines the technologies of microbial fuel cell (MFC) and battery deionization (BDI). The integrated system utilizes a nickel hexacyanoferrate (NiHCF) electrode with a selective affinity for NH 4 + , enabling the achievement of NH 4 + recovery with low energy demand and an appropriately operated voltage. Within this integrated system, the MFC initially degrades the organic matter in the water, generating bioelectricity that powers the subsequent operation of the BDI unit. The MFC-BDI system operated without requiring additional energy input, achieving a voltage of approximately 0.55 V and a charge efficiency of 81%. As demonstrated, with regard to NH 4 + , the MFC-BDI system exhibited a mean deionization capacity of 0.32 mmol/g, surpassing that of other cations in wastewater. Moreover, the selectivity coefficient of NH 4 + over Na + was found to be 16.28, indicating the preferential intercalation of NH 4 + over Na + by the NiHCF cathode. This finding introduces a proof-of-concept for integrating the MFC and BDI systems, providing valuable insights to develop a sustainable approach for NH 4 + recovery.

The Manggarai water Gate is a measurement point strategically located to measure Jakarta's flooding magnitude that keeps increasing from year to year. The 2015s gate capacity improvement underscores this importance. This paper applies a machine learning model that utilizes an atmospheric approach to predict the Manggarai water level as output. In the process, optimization is done by comparing three spatial input sizes and performing a sensitivity analysis of the input variables. Using a simple recurrent sequence, the model can predict the water level with a coefficient of determination (R2) reaching 0.7 using 18-hour recurrent data. This study can be used as the basis for further development that can take satellite data lead time advantage that is crucial for the early warning system. © 2021 IEEE.
