However, the impact of RBV on the biological treatment of wastewater has rarely been reported to date. This study investigates the influence of RBV on the enhanced biological phosphorus removal process by controlling the influent RBV concentration and elucidates the underlying mechanisms. The results indicated that low concentrations of ribavirin (below 0.05 mg/L) did not significantly affect the EBPR efficiency, while concentrations exceeding 0.1 mg/L significantly reduced the removal of chemical oxygen demand (COD) and soluble orthophosphate, with higher exposure concentrations leading to poorer EBPR performance. High concentrations of RBV decreased the concentration of organic matter in the sludge and its settleability. At an RBV concentration of 2.0 mg/L, the sludge volume index increased, but the volatile suspended solids concentration decreased to 3.25 ~ 3.41 g/L. Exposure to RBV increased the content of extracellular polymeric substances (EPS), with higher exposure concentrations leading to a more significant increase in EPS content, notably in the content of protein. RBV reduced the specific oxygen uptake rate of microorganisms, with higher exposure amounts resulting in a more pronounced decrease in specific oxygen uptake rate (SOUR). RBV also promoted the release of reactive oxygen species and lactate dehydrogenase, reducing microbial metabolic activity.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"44 3","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144171210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Efforts to enhance certain green environmental indicators in order to achieve sustainability have been driven by the necessity to bridge these disparities. The first empirical data addressing the question of whether environmental policy strictness, environmental technology, renewable energy, and digitalization contribute to or worsen ecological damages in the economies of the BRICS countries between 1990 and 2022 is presented in this study. The theoretical evidence emanates from the novel STIRPAT framework, which enables the incorporation of other control variables, such as urbanization, economic growth, foreign direct investment, and globalization. Second-generation estimators form the basis for the empirical verification. The results indicate that digitalization, renewable energy, and environmental technology all contribute positively to ecological well-being. However, stringent environmental regulations appear to have limited impact on advancing the BRICS countries. Nonetheless, strict environmental regulations seem to be ineffective in propelling the BRICS. Moreover, it is evident that globalization, economic growth, urbanization, and foreign direct investment all exacerbate ecological damage. The panel findings are supported by a nation-level analysis. Additionally, the model calculations identify one-way and two-way connections as the two causal pathways. The study's conclusions are utilized to propose policy recommendations.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"44 3","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144171459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, a systematic analysis of the physicochemical properties of desulfurization gypsum is essential, with a specific focus on heavy metal content, occurrence form, and leaching characteristics. The results indicate that desulfurization gypsum is a powdery particle with high water content, primarily composed of CaSO4·2H2O and CaSO4·0.5H2O. The heavy metal content in desulfurization gypsum from Shanxi province consistently follows the order of Pb > Zn > As > Cr > Mn > Ba > Cu > Ni > Cd; and Cu, Zn, Ni, Cr, Mn, and Ba are predominantly present in an effective form, which increases their potential for environmental migration. Notably, the concentrations of heavy metals in the leachate obtained through the three standard leaching methods do not exceed regulatory standards. During the column leaching process, heavy metals are released into the leachate at varying rates. The dynamic leaching characteristics of each heavy metal are influenced by their contents and their chemical speciation. Particular attention should be given to the dynamic migration of Ni and Pb from desulfurization gypsum during its storage, disposal, and resource utilization.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"44 3","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144171992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A bibliometric analysis of 250 publications from 2000 to 2024 reveals increasing global research interest, with significant contributions from China, India, and the USA. Key themes identified include adsorption mechanisms, activated carbon modification, and biosorption techniques. Biomass-based adsorbents, such as corn cob, Ulva lactuca, and Eichhornia crassipes, demonstrate high adsorption capacities, ranging from 80 to 250 mg/g for hexavalent chromium (Cr(VI)), depending on preparation methods and operational conditions. The review highlights advanced preparation techniques, including chemical activation with KOH and H₃PO₄, which enhance surface area up to 1500 m2 g−1, significantly improving adsorption performance. Despite promising results, challenges persist in scaling up for industrial applications, inconsistent performance across biomass types, and the need for cost-effective regeneration methods. Incorporating nanotechnology, such as metal oxide nanoparticles, has improved removal efficiencies by up to 30%, broadening potential applications.

The urgency of this challenge is underscored by the ongoing United Nations negotiations for a legally binding instrument on plastic pollution. Given the complexities of the plastic waste stream and recycling processes, exploring innovative solutions is crucial. Advanced recycling has been offered as a potential solution to combat the influx of plastic waste, and we examined its connections with post-use plastic feedstock and human health, providing a neutral overview without endorsing any specific solutions. The debate on classifying these technologies as recycling highlights the need for universal definitions and transparency in waste management. Using the United States as a case study, different approaches to advanced recycling, their implementation status, and related policy gaps are compared. Simplified plastic formulations, transparent reporting on the environmental footprint of advanced recycling, and increased research investments may be needed to pave the way for a more sustainable future in plastic waste management.

The manuscript is focused on exploring the possibilities of synthetic electrospun polymer nanofibers for the adsorption of water pollutants like dyes. Here in this work, electrospun synthetic poly(methyl methacrylate) (PMMA) nanofibers are presented as adsorbents for dyes, taking advantage of the porosity of nanofibers. The further possibilities of electrospinning are also explored to modify these nanofibers, and the modified nanofibers lead to enhanced adsorption. The adsorption of dye onto the nanofibers and their interactions are proven by various spectroscopic analyses like FTIR, UV, and so forth. Incorporation of dye into PMMA nanofibers influences the optical properties of all three types of PMMA nanofibers, with a red shift in their peak position and enhancement in photoluminescence (PL) intensity. The bathochromic shift of pure and structurally modified electrospun PMMA nanofibers after adsorbing methylene blue dye is evidenced by PL studies of the samples.

Unlike conventional studies, this research adapts these cycles to Martian conditions, focusing on three working fluids: helium, nitrogen, and carbon dioxide (CO2) for the BC, and R600, R245fa, and R600a for the ORC. By evaluating thermodynamic performance, resource utilization, and logistical feasibility, this work identifies optimal fluid–cycle combinations to address Mars' energy needs, enabling reliable and efficient energy systems for long-term human settlement. The novelty lies in incorporating Martian-specific conditions, such as the planet's low atmospheric pressure and extreme temperatures, into the thermodynamic modeling of these cycles. The study also highlights the innovative use of locally available CO2 to minimize reliance on transported resources, offering a sustainable solution for extraterrestrial energy production. These findings provide critical insights for the design and optimization of energy systems that can withstand Mars' harsh environment. This research benefits the scientific community by advancing knowledge on energy production in extraterrestrial environments and offering a framework for designing efficient, resource-optimized power systems for space exploration. The proposed solutions have potential applications in future Mars missions and long-term colonization strategies, serving as a blueprint for sustainable energy management in other planetary settings.

Enhancing fuel efficiency and reducing emissions in these engines are critical goals, and machine learning (ML) techniques offer novel solutions for achieving them. This study investigates the use of ML models, specifically random forest regression (RFR) and polynomial regression (PR) to predict key combustion characteristics, namely cylinder pressure and heat release rate (HRR), in a dual-fuel diesel engine powered by a ternary blend (TB) and acetylene. The experimental setup involved modifying a conventional diesel engine to operate in dual-fuel mode, using a TB fuel comprising 70% diesel, 20% waste cooking oil biodiesel (WCOB), and 10% methanol by volume. The cylinder head, piston crown, and intake/exhaust valves were coated with partially stabilized zirconia (PSZ) to improve combustion efficiency. The RFR model achieved an impressive R2 score of 0.9987 for cylinder pressure and 0.9878 for HRR predictions, with corresponding mean absolute error (MAE) values of 0.124 and 0.021, indicating high predictive accuracy and minimal deviation from experimental values. The PR model, while capturing some nonlinear trends, performed less reliably, with R2 scores of 0.7689 for cylinder pressure and 0.6720 for HRR. These results underscore the RFR model's robustness in predicting complex combustion behavior, offering a reliable, cost-effective approach to optimize fuel efficiency and emission reduction in diesel engines. The findings suggest that implementing ML models, particularly RFR, can aid in tuning engine parameters for sustainable fuel blends, contributing to reduced greenhouse gas emissions and improved fuel efficiency.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"44 3","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144171298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
