The clothing production industry with a fashion approach has also created many environmental challenges in this regard, so the aim of this research is to identify environmentally friendly components in the fashion industry. First, by reviewing the existing research records on the sustainable fashion industry in Iran and the world, the main components of environmentally friendly fashion and the items related to each component were identified using the method of deductive content analysis, and then a final questionnaire was prepared. The questionnaire was completed by 110 clothing fashion experts in the statistical population of Isfahan province. Subsequently, semi-structured interviews were conducted with 7 activists in this field to assess the feasibility of establishing sustainable fashion in Iran. The results showed that variables related to raw materials used, production process, and product storage and consumption have a significant impact on determining the components of environmentally friendly fashion. It was also found that the current state of the sustainable fashion industry in Iran has weaknesses and shortcomings in terms of recycling and packaging cycles. In addition, the main categories of cultural infrastructure, legal requirements, economic infrastructure, technological infrastructure, and process engineering are considered and effective for implementing the fashion industry in the context of Iranian society.</p>http://journal.eri.acecr.ir/Article/49698Fashion industry environment clothing design clothing production process.perپژوهشکده محیط زیست جهاددانشگاهیپژوهش و فناوری محیط زیست2676-30602676-30602026-021018articleSayyed Mohammadreza Sedehimrsedehi@ut.ac.ir1Zahra Malekiz.mleki@chmail.ir2Fatemeh Norouzi Palanganifateme.n1369@gmail.com3Ahmadreza Rastegarrastegar_a21@chmail.ir4Mohammad Khakpourmohammadkhakpour@gmail.com5Ph.D. Student, School of Mechanical Engineering, College of Engineering, University of Tehran, Tehran, IranDepartment of Engineering, Gonabad University, Gonabad, IranDepartment of Materials and Metallurgical Engineering, Amirkabir University of Technology, Tehran, IranFaculty of Economics and Administrative Sciences, Ferdowsi University, Mashhad, IranFadak Machinery Complex, Gonabad, Iran<p style="text-align: justify;">Sustainable approaches to material recycling are crucial for reducing the environmental footprint of manufacturing processes. In this study, machining chips are utilized as a valuable resource for recycling, thereby enabling both waste reduction and the development of more cost-effective and environmentally sustainable production processes. Through this method, powder production for advanced manufacturing techniques such as Spark Plasma Sintering (SPS) is proposed as an efficient and environmentally sustainable alternative to conventional machining methods. In this research, a closed-loop recycling process was established using CK45 steel, where machining chips were successfully converted into powder feedstock and consolidated into bulk specimens. These specimens were subjected to hardness testing and X-ray diffraction (XRD) analysis. The results demonstrate that this method not only enhances mechanical properties, including an increase of approximately 30 hardness units, but also provides measurable environmental advantages compared to traditional machining. The application of Spark Plasma Sintering facilitates the fabrication of components with advanced performance characteristics while reducing material waste and associated environmental risks. These findings provide a new perspective for critical industries, such as aerospace and automotive, where environmental impact reduction and efficiency enhancement are achieved in parallel with the advancement of sustainable technologies.</p>http://journal.eri.acecr.ir/Article/50239Steel Recycling Machining Chips Spark Plasma Sintering (SPS)perپژوهشکده محیط زیست جهاددانشگاهیپژوهش و فناوری محیط زیست2676-30602676-30602026-021018articleReza Fateminiarf_shahkaram@yahoo.com1<p style="text-align: justify;">Due to the global water crisis, the treatment and reuse of industrial wastewater, particularly in water-intensive industries such as petrochemicals, has become a key strategy for sustainable water resource management. In recent years, growing awareness of water scarcity and water pollution, together with environmental regulatory requirements and the high costs associated with wastewater disposal, has led to increased attention toward Zero Liquid Discharge (ZLD) technology. This article introduces ZLD systems and examines their applications across various processes and operations in the petrochemical industry. Furthermore, the advantages, challenges, and proposed solutions for managing existing challenges are discussed. The study also reviews process and technological development trends, market demand for ZLD systems, and their anticipated growth prospects</p>http://journal.eri.acecr.ir/Article/50326Petrochemical industry Wastewater treatment Technology Zero Liquid Discharge (ZLD) systemperپژوهشکده محیط زیست جهاددانشگاهیپژوهش و فناوری محیط زیست2676-30602676-30602026-021018articleabolghasem golkhandangolkhandana@gmail.com1ali rostamirostamiali@ut.ac.ir2Kosar Alibeigibanikosar.alibeigi@uc.ac.ir3PhD in Public Sector Economics, Department of Economics, Faculty of Economic and Administrative Sciences, Lorestan University, Khoram Abad, Iran.M.Sc.

Conversely, dependence on oil resources may weaken the positive impact of green technologies and clean energy on environmental quality by undermining institutional quality and good governance. Accordingly, this study investigates the effects of green management measures and policies (including green technologies and clean energy), oil rent, and their interaction on the Environmental Load Capacity Factor (LCF) in Iran, calculated as the ratio of ecosystem biocapacity (supply side) to ecological footprint (demand side), over the period 1990&ndash;2022. To this end, a novel Fourier bootstrap ARDL (F-ARDL) approach is employed. The results indicate that the long-run effects of green management measures and policies and oil rent on LCF are positive and negative, respectively, as expected. The interaction effect between green management measures and policies and oil rent on LCF is negative, suggesting that oil rent weakens the beneficial impact of green technologies and clean energy on environmental quality and thereby supports the resource curse hypothesis over the study period. Furthermore, economic growth and urbanization exert a negative and statistically significant effect on LCF, confirming the pollution halo hypothesis. Accordingly, it is recommended that appropriate policies be formulated and implemented to reduce dependence on oil revenues and allocate a portion of oil revenues to investment in suitable and environmentally friendly technologies through the establishment of green funds</p>http://journal.eri.acecr.ir/Article/50786Oil Rent Green Technologies Clean Energy Load Capacity Factor Interaction Effect Fourier ARDL Iran. perپژوهشکده محیط زیست جهاددانشگاهیپژوهش و فناوری محیط زیست2676-30602676-30602026-021018articlemokarram ravanbakhshmokarramravanbakhsh@gmail.com1Maedeh Ghorbanpourmaede.ghorbanpour@gmail.com2Arman Anarakiarman.seven10050@gmail.com3PhD graduated in Rangeland Science and Engineering, Sari University of Agricultural Sciences and Natural Resources, Mazandaran.

Human societal development and increased anthropogenic activities have caused land degradation and altered land use patterns, consequently intensifying erosion and sedimentation. Assessing the impact of watershed rehabilitation operations on reducing soil erosion and sediment yield is essential to evaluate their effectiveness and inform optimal implementation strategies. This study evaluated implemented watershed conservation operations and their effects on erosion and sedimentation rates in the Alanza watershed from 2016 to 2023, comparing post-implementation conditions with pre-project baselines using the empirical MPSIAC model. Results indicate that conservation and rehabilitation operations reduced the sediment delivery ratio from 114 to 101 (11.4% decrease) and lowered the specific sediment yield per unit area across the watershed from 3009 m&sup3;/year to 1587 m&sup3;/year (47% reduction) before and after implementation, respectively. Overall, findings demonstrate that integrated biological and mechanical measures in the Alanza watershed can serve as an optimal strategy for sedimentation mitigation. However, sustaining these outcomes requires full and precise execution of the regional management plan, including: optimal budget allocation for unimplemented mechanical operations in designated areas, expansion of biological interventions (e.g., reseeding and rangeland exclosure), stakeholder education and local community engagement, reduced livestock grazing pressure, and continuous monitoring of erosion-sedimentation dynamics.</p>http://journal.eri.acecr.ir/Article/51266Anzali wetland Biological and Mechanical operations Sediment Yield Watershed Basinperپژوهشکده محیط زیست جهاددانشگاهیپژوهش و فناوری محیط زیست2676-30602676-30602026-021018articleAmir Heidarihidari-a@mashhad.ir1Mitra Mohammadimitramohammadi@gmail.com2Reza Esmailiesmaili-r@mashhad.ir3Zeinab Khoramdelzeinabkhoramdel@gmail.com4M.Sc. student of Natural Resources Engineering - Environmental Pollution, Department of Environmental Science, Faculty of Environmental Science, Kheradgarayn Motahar Institute of Higher Education, Mashhad, IranAssistant Professor and Head of Department of Environmental Science, Department of Environmental Science, Faculty of Environmental Science, Kheradgarayn Motahar Institute of Higher Education, Mashhad, IranDeputy of Urban Services of Mashhad Municipality, Environmental Pollutants Monitoring Center, Mashhad, IranB.SC.

For this purpose, after collecting traffic data and air pollutant concentrations, the relationships between these parameters were analyzed using the ARIMA (0,1,1) time series model. The results indicated that the use of time series regression provided a good model fit and high predictive performance for the dependent variables due to the strong correlation coefficients. The relationship between traffic and the concentrations of NO₂, SO₂, and PM₁₀ was significant at the 0.05 level in all studied stations, while for CO and PM₂.₅, the relationships were not significant only at the Khayyam and Khaghani stations, respectively. The greatest impact of traffic on CO, NO₂, and SO₂ concentrations was observed at the Emamiyeh station, such that each unit increase in traffic resulted in increases of 0.335, 0.878, and 0.487 units in these pollutants, respectively, during 2017. The highest influence on PM₂.₅ and PM₁₀ levels occurred at the Chaman and Khaghani stations, where each unit increase in traffic led to increases of 0.375 and 0.385 units in the concentrations of these pollutants, respectively. Overall, the findings showed that the concentrations of all air pollutants increased with rising vehicle traffic.</p>http://journal.eri.acecr.ir/Article/49376Air pollution Air pollutants Traffic Mashhad Metropolis Time Series Model
