These limitations fail to capture dynamic pollutant behaviors or account for implicit lifecycle losses, leading to suboptimal remediation decisions. To provide a robust scientific tool for precision management, this study constructs a Process-Driven 3D Spatio-Temporal Quantification (3D-STQ) model. This model is underpinned by a novel Dynamic Retention Equation for Soil Pollutants (DRE-SP), which systematically couples multi-source input fluxes, biodegradation, hydrodynamic migration, and adsorption-desorption kinetics. By integrating adaptive 3D meshing with the NSGA-II genetic algorithm, the model optimizes the trade-offs between remediation cost, time efficiency, and environmental risk. Field validation at an electroplating site demonstrated high precision, with a pollutant concentration coefficient of determination (R<sup>2</sup>) of 0.96 and a negligible 0.1% deviation in crop yield loss prediction. Furthermore, application at a pesticide-contaminated site revealed that the model-optimized strategy reduced total lifecycle costs by 32.2% and shortened project duration by 41.7% compared to traditional methods, while maintaining 96.2% prediction consistency. This study demonstrates that the proposed dynamic framework significantly enhances the accuracy of damage quantification, offering a valuable decision-support tool for sustainable contaminated site remediation and cost control.</div></div>","PeriodicalId":20743,"journal":{"name":"Process Safety and Environmental Protection","volume":"215 ","pages":"Article 109163"},"PeriodicalIF":7.9,"publicationDate":"2026-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148289002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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 paper presents a novel approach for the separation of fats from wastewater, and evaluates their potential for use in the production of bio-polyols. The study included a comprehensive characterization of the fat fraction, including infrared spectroscopy (FTIR) analysis, an examination of fat content, an elemental analysis of fats, and an assessment of the calorific value of fats through determination of calorific value and heat of combustion. Moreover, thermal analysis investigations have been performed using TG and DSC methods, as well as decomposition behaviour using pyrolysis coupled with gas chromatography-mass spectrometry (Py-GC/MS) has been studied. The results show that the recovered fat fraction contains up to 60% fats. The results further indicate that fats from sewage sludge contain a mixture of fatty acids, esters and hydrocarbons, which are key components for the synthesis of bio-polyols. The use of fat fraction from wastewater can significantly contribute to the reduction of waste and the development of sustainable technologies in the chemical industry.

In the proposed system, the thermal coupling of the PV and PRO subsystems significantly improves the output power. The SOFC operates reliably, providing stable power and thus reducing the volatility of the renewable energy system.

This minimizes energy waste and ensures efficient energy conversion, enabling maximum energy utilization efficiency. Incorporating MPPT control into the system improves resource utilization efficiency and environmentally friendly industrial production, enhancing sustainability. Therefore, this work designs an MPPT control strategy that combines the triangulation topology aggregation optimizer (TTAO) and giant armadillo optimization (GAO) algorithms to enhance control performance under fluctuating environments.

This review critically examines the application of pressure-driven, thermally driven, and concentration-driven membrane processes across major hydrometallurgical stages, including solid–liquid separation, solution purification, metal recovery, concentration, and acid regeneration. Of particular interest are recent advances in the selective recovery of precious metals and rare earth elements using functionalized membranes, as well as the integration of hybrid membrane systems for simultaneous resource recovery and acid recycling. Beyond summarizing reported studies, the review evaluates fouling behaviour, membrane stability under corrosive conditions, scale-up barriers, and the current limitations of techno-economic and environmental assessments. The analysis indicates that although MST has demonstrated considerable potential in laboratory and pilot-scale studies, industrial implementation remains constrained by membrane durability, fouling control, limited long-term operational data, and the lack of standardized performance benchmarking.
