The utilisation of biosolids (stabilized sewage sludge) derived products as adsorbents was explored to contribute to sustainable sludge management. Biosolids were subjected to a mild acid (10% v/v HNO₃) and alkali (0.5 M NaOH) treatment at ambient conditions followed by pyrolysis at 450 °C. R-COOH functional group was introduced to the biochar surface by HNO₃ treatment followed by the ionic replacement of H⁺ with Na⁺ from NaOH treatment to form R-COO-Na group. The surface functional groups were studied via XPS, EDS, and FTIR analyses. The chemical treatment achieved on average about 75% removal of heavy metals from the product. The modified biochar showed a high ammonium adsorption capacity from both synthetic wastewater (17.03 mg g⁻¹) and real digester effluent (16.1 mg g⁻¹), higher than that of raw biosolids biochar (5.23 mg g⁻¹ in synthetic effluent). The N-laden biochar (composed of 1.6 wt% surface nitrogen) with reduced heavy metals content could be applied to land as a slow-release nitrogen fertiliser. Economic analysis reveals a net present value of $1 million and a payback period of 8 years. This approach potentially reduces environmental pollution and provides economic benefits via cost-effective waste treatment solutions.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":589,"journal":{"name":"International Journal of Environmental Science and Technology","volume":"22 8","pages":"6665 - 6680"},"PeriodicalIF":3.0,"publicationDate":"2024-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13762-024-06069-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143612215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To obtain more effective bacteria, halotolerant bacteria with plant growth-promoting attributes were isolated and screened out from salt-affected areas. Their abilities to alleviate salt stress on maize were further evaluated. The results showed that 11 of 268 strains displayed at least three plant growth-promoting traits, and some of them promoted growth, decreased Na⁺ accumulation and increased K⁺/Na⁺ ratios of maize seedlings under salt stress. The elongation and biomass of maize seedlings were significantly correlated to K⁺/Na⁺ ratios of maize seedlings after strain treatment, not the P-solubilization of strains. The maize seedling growth, Na⁺ and K⁺ accumulation were affected by indole-3-acetic acid levels that plant growth-promoting bacteria secreted. Among 11 strains, Hm18 and Pt07 which belong to <i>Bacillus altitudinis</i> and <i>Pantoea agglomerans</i>, respectively, increased maize seedling growth and K⁺/Na⁺ ratio in maize seedlings. Strains Hm18 and Pt07 alleviated growth inhibition and cell membrane injuries of maize seedlings caused by salt stress in soil. Additionally, Hm18 and Pt07 reduced Na⁺ accumulation and increased K⁺/Na⁺ ratios in maize under soil conditions as well. Overall, plant growth-promoting bacteria alleviated the detrimental effects of maize seedlings caused by salt stress through increasing K⁺/Na⁺ ion balance, which correlated to indole-3-acetic acid produced by bacteria. Hm18 and Pt07 increased salt tolerance and growth of maize seedlings grown in saline soil. These results provided potential beneficial bacteria resources for maize production in saline soil.</p></div>","PeriodicalId":589,"journal":{"name":"International Journal of Environmental Science and Technology","volume":"22 8","pages":"6637 - 6650"},"PeriodicalIF":3.0,"publicationDate":"2024-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143612213","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 study focuses on real application of floating power plant, and the information obtained from the analysis is expected to contribute to the design of new or existing systems. Calculations demonstrate wave deformation in severe wind, yielding heterogeneous force distributions. The compressed air flow lines align with areas characterized by high-speed flow, with wind speeds ranging from 30 to 50 m/s. The wave kinetic energy increases due to the wind, resulting in high forces being applied to the surface of the Floating Photovoltaic platform. Turbulence Kinetic Energy exhibits higher values in front of and on the surface of the platform due to the disruption of the airflow. As a result of direct interaction with waves and wind, the front section of the floating system experiences significantly higher loads. The total pressure on the entire surface of the floating platform reaches maximum values of up to 38.677 kN/m². When compared with various analytical methods, it has been observed that the Goda and Morison methods yield closer results. This discrepancy is believed to stem from the omission of wind interactions and platform structure considerations in the analytical methods.

The impact on the environment, on the lives of living beings, and on the pollution and destruction of nature is escalating day by day. Given the scale of the problem, there is an urgent need to identify and implement solutions. The strategies to be developed should be innovative and aligned with today’s technological advancements, including artificial intelligence. To this end, the aim of this study is to present an original fuzzy decision-aided framework for ensuring sustainable e-waste management within the context of key Industry 4.0 strategies. This study uses original data and is supported by expert opinion. Additionally, the advantages of continuous function-valued intuitionistic fuzzy sets (CFVIFSs), an innovative approach, are utilized. The criteria weighting is enhanced by the Kullback–Leibler divergence measure formed with these CFVIFSs, adding another dimension to the study. Results are achieved using Goal Programming (GP) approach in strategy selection. In addition, detailed and comparative analyses are conducted to evaluate strategy rankings from different perspectives. In the sensitivity analysis, the rankings are obtained according to the varying weights of criteria. Furthermore, The Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) and The Simple Additive Weighting (SAW) method are employed for the comparative analysis. Moreover, Spearman’s rank correlation coefficients are calculated to examine the consistency of each case. Overall, this study, which brings together different perspectives, provides valuable managerial insights to a global problem.</p></div>","PeriodicalId":589,"journal":{"name":"International Journal of Environmental Science and Technology","volume":"22 8","pages":"6595 - 6620"},"PeriodicalIF":3.0,"publicationDate":"2024-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143612209","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}

It was found that the biodegradation was higher than 30% for both polyelectrolytes, indicating that these compounds are moderately biodegradable. The aim of this work is to study the effect of the synthesized polyelectrolytes on the formation of CaSO₄-scales and the corrosion of AISI─1810 carbon steel. Static precipitation experiments were carried out to investigate the effect of the polyelectrolytes on the precipitation of CaSO₄-scale. The results showed that both polyelectrolytes are effective scale inhibitors under static conditions, with high efficiencies (&gt; 80%) at low concentrations. The polyelectrolyte influence on the corrosion of AISI carbon steel was examined by open circuit potential (OCP), linear polarization resistance (LRP) and potentiodynamic polarization studies. The results showed that the polyelectrolytes provided corrosion inhibition efficiencies ranging from 60 to 90%. Compatibility experiments were carried out to investigate the stability of the synthesized polyelectrolytes in the corrosive media and to observe the influence of these compounds on the inhibition of CaSO₄-scale. The polyelectrolytes were shown to be compatible with the corrosive solution.

The analysis revealed significant improvements in sludge dewaterability, especially with the combined Fe(III) + CaO and Fe(III) + MgO treatments, with the latter demonstrating a marginally superior performance. The adsorption of hydrophilic loosely bound and tightly bound extracellular polymeric substances (LB-EPS and TB-EPS) onto hydroxide complexes facilitated the formation of a more stable and porous structure, which enhanced the release of bound water. However, certain treatments such as Fe(II)-NaClO and PAM presented challenges to dewatering due to excessive oxidation and the formation of a highly viscous gel structure, respectively. Furthermore, the exploration underscored the critical role of protein concentrations within soluble extracellular polymeric substances (S-EPS) in mediating heavy metal translocation, particularly Zn, Cu, and Ni, from the solid to the liquid phase of LS. An increased risk of leaching was observed with the Fe(II)-NaClO treatment, associated with over-oxidation-induced solubilization of S-EPS proteins. Notably, the findings elucidated effective mechanisms for immobilizing heavy metals. Combined treatments (Fe(III) + CaO and Fe(III) + MgO) were particularly effective in containing heavy metals, with varying mechanisms contributing to their removal. Specifically, the adsorption and precipitation of ferric hydroxide complexes with calcium or magnesium were crucial in the removal of Cr, Pb, and Hg, while the removal of Zn, Cu, and Ni was predominantly facilitated by the formation of heavy metal-protein-hydroxide co-precipitates.</p></div>","PeriodicalId":589,"journal":{"name":"International Journal of Environmental Science and Technology","volume":"22 8","pages":"6573 - 6584"},"PeriodicalIF":3.0,"publicationDate":"2024-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143612307","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}
