The experimental system was composed of six constructed flooded systems. The flow was frequently monitored by direct measurement, and subsequently, the pH, influent, and effluent concentrations of the variables total solids (TS) and total suspended solids (TSS) and chemical oxygen demand (COD) were determined. The results showed that the average removal of total solids (TS) and total suspended solids (TSS) did not change significantly (p > 0.05) with increasing applied load in vertical flooded systems. While statistically significant differences (p < 0.05) were observed for ST in VFCW3 in Phase III (801–540 mg.L−1, 33%) and for TSS in VFCW2, which showed 48% removal in Phase III (122–62 mg.L−1, 48%), indicating that specific configurations can improve system efficiency. On the other hand, the average removal of total suspended solids (TSS) did not change significantly (p > 0.05) with increasing applied load in horizontal flooded systems. However, the average removal of total suspended solids (TSS) increased significantly (p < 0.05) with increasing applied load in horizontal flooded systems. Therefore, it can be concluded that the COD removal efficiencies, in general, increased with the increase in the applied organic load, reaching approximately 50% (307–271 mg.L−1 VFC3 and 307–145 mg.L−1 HFCW3) for the VFCW-HFCW set.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"44 4","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145022197","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}

This research focuses on electrifying remote locations with renewable energies with reduced GHG emission. Easter Island is more than 3500 km from the mainland and relies entirely on diesel generators for electricity. The diesel generator emits more emissions for supplying power to Easter Island, which will affect the environment. The alternative solution is identified by implementing renewable sources such as solar, wind, and tidal power in Easter Island. The sensitivity and optimization results are performed for Easter Island using HOMER software. The monthly average solar irradiation and wind speed are downloaded from the NREL database. The original load power for Easter Island is considered in this research work to determine the suitable power sources with less GHG emission. The results show that the solar/DG/tidal mix is suitable for Easter Island, with life cycle cost and energy cost at $22,816,140 and $0.147, respectively. The results also show that the GHG emission is 93.53% less when comparing the solar/DG/tidal hybrid system with the system consisting of a diesel generator alone. The result of the sensitivity analysis illustrates that there is an impact on varying maximum limits on CO2 emission, solar cell temperature, solar temperature coefficient of power, discount rate, and inflation rate. The change in load demand and solar degradation for multiple-year variations is also analyzed.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"44 4","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145022122","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}

The investigation focuses on two different walnut shell sizes (4 mm and 8 mm) distributed uniformly at the basin of a CSS with a surface area of 0.1 m2. The still features a 3 mm-thick plastic conical cover and is filled with 1 liter of water. The study evaluates two modified stills—one with 4 mm walnut shells (CSS-WS4) and another with 8 mm walnut shells (CSS-WS8)—against a conventional conical solar still (TCSS) serving as the control. The experimental results reveal that the cumulative distillate yield for the TCSS, CSS-WS4, and CSS-WS8 are 4.80, 6.90, and 6.00 L/m2/day, respectively. The presence of walnut shells significantly improves the water output, with CSS-WS4 achieving a 43.75% increase and CSS-WS8 a 25.00% increase compared to the TCSS. Furthermore, the economic analysis indicates a reduction in the recovery period, with CSS-WS4 and CSS-WS8 requiring 22 and 25 days, respectively, compared to 31 days for the TCSS. The results highlight that the performance enhancement is primarily attributed to the superior heat retention properties of walnut shells, which improve evaporation rates within the still. This study underscores the potential of incorporating walnut shells as a cost-effective and eco-friendly solution for optimizing solar distillation efficiency.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"44 4","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145022121","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}

Ultraviolet–Visible (UV–Vis) spectroscopy revealed a strong surface plasmon resonance (SPR) band characteristic of isotropic AuNPs, further validating their formation. Additionally, X-ray diffraction (XRD) analysis confirmed the crystalline nature of the synthesized nanoparticles, with diffraction peaks corresponding to the face-centered cubic structure of gold. The growth of isotropic AuNPs suggests a homogeneous dispersion of the mold in the aqueous environment, a slower reduction rate of AuCl₄− ions, and the mold's capability to facilitate the internal formation of gold seeds. Remarkably, these AuNPs demonstrated potent bactericidal activity against antibiotic-resistant Staphylococcus aureus, effectively inhibiting its growth.

As one of the most obvious representatives of human activities, the development and change of land use intensity (LUI) also deeply affects the ecosystem service ability. Therefore, it is of great significance to understand the coordinated development between LUI and ecosystem service capacity for making a reasonable decision and regional development policy. This paper quantified the ecosystem service function in the Hexi region from 2000 to 2020 using the InVEST model and analyzed the coupling coordination relationship between ecosystem services (ESs) and LUI using the coupled coordination degree model (CCD) based on calculating LUI. The results showed that: (1) From 2000 to 2020, the LUI in the Hexi region decreased from southeast to northwest in space and increased first and then decreased in time. (2) The comprehensive ecosystem service index (CESI) of the Hexi region showed a decreasing trend from 2000 to 2020, with large fluctuations, and its stability needs to be enhanced. CESI showed a spatial distribution pattern of high in the south and low in the north because of the climate conditions and land use patterns. (3) The CCD between LUI and CESI transformed from a reluctant coordination level to a moderate level of coordination and gradually improved over time from 2000 to 2020. The results can provide scientific references for the rational utilization of land resources, the protection of the ecological environment, and sustainable development for similar eco-fragile regions.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"44 4","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145021783","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}

The present study examines the effect of economic growth (Y, GDP), service sector (SVA), and renewable and non-renewable energy consumption (RE, NRE) on environmental quality (CO2, E) and the dynamic interdependence among them for China spanning the period 1980–2021 using the linear and non-linear autoregressive distributed lags (ARDL, NARDL) techniques. Granger causality tests are employed to check for causalities among the underlying variables. The main results showed for the ARDL model the existence of unidirectional causality from GDP to SVA and bidirectional causality between RE and NRE and RE and CO2 in the short term. However, there is no short-run causality between NRE, E, GDP, and SVA. According to the NARDL, the results of the empirics mentioned a one-way causality running from RE+ to all the variables and a one-way causality from SVA to RE+. Granger shows bidirectional causality between RE+ and CO2 and between RE+ and NRE in the short run. Nevertheless, a negative shock in renewable energy negatively affects CO2 emissions in the long term. China's policymakers will increase the share of non-fossil fuels in primary energy and invest more technology in the service sector, including buildings and transport. To reduce environmental pollution, the government, policymakers, and regulatory agencies will place more of their attention on less energy-intensive and polluting industrial output, moving from more polluting activities to a less polluting services sector.

The optimum conditions were achieved at pH 2, a concentration of 1100 mg/L, and a contact time of 60 min with an adsorption capacity of 45.83 mg/g at room temperature. The adsorption process of indigo carmine followed the Freundlich isotherm model (R2 = 0.9572), indicating the formation of a multilayer adsorption. The kinetic data were fitted to the pseudo-second-order kinetic model. Thermodynamic adsorption studies indicated that the adsorption process was spontaneous and exothermic. The Fourier Transform Infra-Red (FTIR) spotted that the S=O group wavenumber was shifted from 1094.73 to 1095.57 cm−1 after indigo carmine uptake. The Scanning Electron Microscopy (SEM) and Brunauer-Emmett–Teller (BET) exhibited that the adsorbent surface has become smoother and a reduction of surface area after adsorption occurred. x-ray Fluorescence (XRF) analysis indicated that the percentage of Sulfur (S) increased, confirming indigo carmine existence in the adsorbent. Thermogravimetric Analysis (TGA) denoted greater weight loss at 230°C as the active sites of the biosorbent had been damaged. The percent removal of kapok husk did not significantly change after fourdsorption–desorption cycles using 30% glycerol as the desorbing agent. Kapok husk has successfully removed indigo carmine from batik textile wastewater by as much as 77.04%.

The temperature reduction from the novel PV/SW system produced a 43% improvement in average electrical efficiency relative to the standard PV system and achieved improved efficiency by 12% above the (PV/W) system.

A two-step optimization strategy for the production of activated carbon is employed to ensure the optimum findings. The synthesization of pistachio shell-derived activated carbon (PSAC) includes carbonization at 500–700°C temperature followed by a KOH activation with varying fraction ratios of biochar: KOH in the range of 1:2–1:6 at 850°C under the inert environment. The optimized carbonized product is found to be at 562.5°C based on the biochar throughput and percentage stable carbon content, considering the effect of moisture content, the molecular mass of carbon and hydrogen, and the H/C ratio in their expressions. Six different composites are also synthesized by varying the fractions of expanded graphite and polyvinyl alcohol. The maximum specific surface area for PSAC is found to be 703 m2/g with micro- and meso-pores, and the greatest CO2 capture capacity through chemisorption alone reaches 0.858 mmol/g at 1 bar. However, adding ingredients to activated carbon to form composites reduces the specific surface area, leading to lower CO2 capture capacity due to partial occupation of adsorption sites. A comparative analysis demonstrates that the proposed biomass-derived carbon exhibits superior potential for CO2 capture, outperforming many sorbents reported in the literature. Additionally, a brief economic analysis is performed on the newly synthesized activated carbon and composite, highlighting their potential for cost-effective CO2 capture applications.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"44 4","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145022119","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}
