The sheer volume of FPW generated and its hypersaline and hazardous nature requires the water to be managed properly, such as underground injection. However, the increased awareness of the adverse environmental impacts associated with underground injection is expected to drive FPW management away from underground disposal. Meanwhile, the lack of data on the chemical constituents and the toxicological characteristics of treated FPW has likely hampered regulatory agencies in developing policies that enable advanced FPW treatment for reuse. Therefore, until a FPW reuse market emerges to justify the costs of advanced treatment, the most viable FPW management strategy for operators is to reduce the volume of FPW for disposal. This study examines the cost and environmental benefits of adopting an on-site thermal evaporation process through data collected from multiple developmental basins – the Rockies, Appalachia, and Haynesville basins using thermal evaporators. We developed a method for assessing the cost-benefit and applied it to a hypothetical scenario for Eagle Ford shale to demonstrate the potential benefits of thermal evaporation.

Plastic waste fuel is a viable alternative to current petroleum-based fuels due to its heating value (44–45 MJ kg⁻¹), deficient moisture and ash content, and nearly neutral pH. The present review explores the feasibility of converting waste plastic to fuels via pyrolysis, a thermochemical conversion technique. Specifically, the review discusses the different types of pyrolysis, the resulting products, and their characteristics. The pyrolysis operating parameters, such as catalyst type, temperature, residence duration, heating rates, and plastic waste type, along with yields, quality, and applications, are also investigated. The review also assesses the characteristics of pyrolytic oil and possible upgradation techniques.

Comprehensive assessments on water resource development are imperative for effective sustainable water planning. However, challenges arise due to mismatches in scale between data sets and methodologies. This study focused on Shanxi Province, a principal coal-producing region in northern China, and conducted an assessment on water resource development and security levels utilizing a dataset from 2011 to 2020 and a comprehensive index method. Future scenarios for water supply and demand were projected for the period of 2021–2035 using the STELLA model. The results showed that Shanxi Province experienced a prolonged process of water resource scarcity, with the supply–demand gap initially widening and subsequently narrowing during the period of 2011–2020. The mean annual development ratios for surface water and groundwater resource surpassed 86% and 34%, respectively. Across the eleven cities in the province, extents of water scarcity exhibited subtle differences, with water shortages occupying 1.4–12.8% of the overall water supply. Proportions of poor, average and good water resource security status in the province were 27.3%, 63.6%, and 9.1%, respectively. Identified water security level indicators included surface water availability, urbanization rate, water consumption for secondary industry, water demand of tertiary industry, wastewater treatment rate, and water demand of eco-environmental systems. These indicators maintained major weights in the assessment on water security, reflecting the inadequacy of available water resource to satisfy supply requirements and to fulfill the demands of social and economic development. Among future forecast scenarios, the least severe water shortage was obtained in the scenario concerning sustainable water resource development. Compared to the baseline development scenario, the water shortage in 11 cities in the sustainable development scenario was attenuated, with an reduction ranging from 10.53% to 78.57%.</div></div>","PeriodicalId":101279,"journal":{"name":"Water-Energy Nexus","volume":"8 ","pages":"Pages 31-44"},"PeriodicalIF":0.0,"publicationDate":"2025-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143609500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Disinfection has been demonstrated to have a good inactivation effect on antibiotic resistant bacteria (ARB) and a certain removal effect on resistant genes compared to the traditional treatment process. However, sub-lethal disinfection effects are inevitable. To improve the study and enhancement of ARGs removal, the abundance and transfer of ARGs across various disinfection techniques under sub-lethal conditions were summarized in the review. Additionally, possible mechanisms of transfer of ARGs under these conditions were also explored. Sub-lethal disinfection has been shown to accelerate the horizontal gene transfer (HGT) of ARGs, thereby increasing potential health risks.

This paper constructs typical rainwater harvesting (RWH) models based on road watering and green space watering reuse pathways, as well as typical flat water year and cistern emptying time in three distinct climate zones of China: Urumqi (located in a semi-arid area), Baoding (located in a semi-humid area), and Shantou (located in a humid area). Using the Infoworks ICM model, long-term simulations (30 years) were conducted to evaluate the economic advantages of rainwater utilization across these climate zones. The Particle Swarm Optimization (PSO) was employed to optimize the cistern volume by integrating Net Present Value (NPV) and Benefit Cost Ratio (BCR). Additionally, multiple nonlinear regression analyses were employed to quantify the relationship between various catchment subsurfaces and the optimal reservoir volume. Sensitivity analyses, including Sobol sensitivity analysis, were performed for parameters such as subsurface characteristics, water price, discount rate, and number of days for emptying the impoundment. The study results indicated that the change curves of NPV and BCR in all three cities exhibit an increasing and then decreasing trend with the increase of reservoir volume under different reservoir setup scenarios. The optimal volume of the reservoir could be articulated through the fitting equation that relates the green space ratio to the road ratio. The discount rate and water price significantly impacted the optimal volume of storage tanks, with the sensitivity of the parameter of the number of days of emptying of the storage tanks to the optimal volume being greater in Shantou, a city in a high humid area. Conversely, in Urumqi, a semi-arid area, the variation of the parameter of greenland rate had a greater sensitivity to the volume of storage tanks.
