چکیده
زمینه و هدف: در ایران صنعت فولاد به لحاظ وجود منابع معدنی مورد نیاز در کشور، توانمندی نیروی انسانی، وجود بسترهای اقتصادی و اثربخشی تولید فولاد در رشد اقتصادی کشور، از اهمیت ویژه ای برخوردار است. بنـابراین بایـد راهکارهایی اتخاذ گردد که ضمن کاهش خطرات محیط زیستی، صنعت فولاد به سمت توسعه پایدار پیش رود. هـدف از پژوهش حاضر ارزیابی و مدیریت ریسک محیط زیستی کارخانه احیای مستقیم به روش EFMEA در شرکت توسعه آهن و فولاد گل گهر می باشد.
مواد و روش ها: در ابتدا با بازدید میدانی تمامی خطرات و جنبه‌های محیط زیستی شناسـایی و بـا استفاده از روشEFMEA ارزیابی شد. RPN با حاصل ضرب احتمال، شدت و بازیافت یا گستره آلودگی به دست آمده است. در نهایت RPN ثانویه پس از تعریف و اعمال اقدامات کنترلی پیشنهادی محاسبه گردید.
یافته ها: در این پژوهش 468 جنبه ریسک محیط زیستی شناسایی شد که از این میزان 258 ریسک در سطح ناچیز، 187 ریسـک در سطح کم، 17 ریسک در سطح متوسط و 6 ریسک در سطح بالا قرار داشتند.
نتیجه گیری: نتایج نشان داد که مهمترین ریسک های موجود در واحد تولید بوده که بیشترین عدد ریسک مربوط به گازهای خروجی دودکش از جنبه انتشار گازهای گلخانه ای می باشد. پس از ارزیابی ثانویه و انجام اقدامات اصلاحی، مشخص گردید که استفاده از روش های مناسب مدیریت ریسک های محیط زیستی، برنامه ریزی صحیح، ارائه راهکارهای پیشگیرانه و اصلاحی می‌تواند از وقوع پیامدهای محیط زیستی جلوگیری و خطرات محیط زیستی ناشی از صنایع را به میزان قابل توجهی کاهش دهد.

چکیده [English]
Background and Objective: The steel industry is highly crucial in Iran due to the availability of mineral resources, manpower capacity, economic platforms, and the effectiveness of steel manufacturing in Iran's economic growth. Therefore, some strategies must be taken to reduce environmental hazards and direct the steel industry toward sustainable development. This study aims to evaluate and manage the environmental risk of a direct recovery plant based on the EFMEA method in Golgohar Iron and Steel Development Company.
Materials and Methods: All environmental aspects and hazards were identified through field visits and analyzed using the EFMEA method. RPN was measured by probability coefficient, intensity, and recovery or extent of pollution. Ultimately, secondary RPN was measured after defining and applying the control measures.
Results: This study identified 468 aspects of environmental risks among which, 258 risks were at a minor level, 187 risks were low-level, 17 risks were medium-level, and six risks were high-level.
Conclusion: the results confirmed that the most substantial risks occurred in the production unit, with the highest risk number related to chimney exhaust gases in terms of greenhouse gas emissions. After secondary assessment and corrective measures were done, it was found that proper methods adopted for environmental risk management, accurate planning, and presentation of preventive and corrective strategies can significantly reduce the environmental consequences and environmental hazards caused by industries.
