چکیده

در هر سال نزدیک به 400 فروند هواپیما در سراسر جهان از رده خارج می‌شوند. بدلیل توسعه صنعت حمل و نقل هوایی این تعداد بطور مداوم در حال افزایش است و انتظار می‌رود که تعداد هواپیماهای خارج از رده طی 20 سال آینده به 12000 تا 14000 برسد. یکی از بزرگترین مشکلات برای هواپیماهای مستعمل چگونگی از رده خارج کردن آنها است. هدف از انجام این تحقیق بررسی گزینه‌های مناسب مدیریت هواپیماها در مرحله پایان حیات با تمرکز بر گزینه بازیافت فلزات (آلومینیوم) به لحاظ اثرات محیط‌زیستی و اقتصادی آن بوده است. لذا در این مطالعه ابتدا به تجزیه و تحلیل وضعیت فعلی ناوگان هوایی کشور پرداخته شده. سپس مقدار آلومینیوم قابل بازیافت از هواپیماهای خارج از رده، میزان ذخیره انرژی و کاهش انتشارات CO2 در نتیجه بازیافت آلومینیوم و همچنین ارزش اقتصادی آلومینیوم قابل بازیافت محاسبه گردیده است. یافته‌ها حاکی از آن بود که با بازیابی آلومینیوم از هواپیماهای خارج از رده در ناوگان هوایی کشور، صرفه‌جویی در انرژی به میزان MJ 157358565.616، کاهش انتشارات CO2 به میزان kg 12539971.392 و سود مالی به میزان 194830064000 ریال حاصل می‌گردد. با توجه به فراهم آوردن مزایای قابل توجه محیط‌زیستی و اقتصادی، بازیافت مواد و قطعات هواپیما گزینه مناسب برای مدیریت هواپیماها در مرحله پایان حیات به نظر می‌رسد.

چکیده [English]

Abstract
Every year around 400 aircrafts are retired and taken out of service worldwide that is expected to increase steadily as aviation industry expands. The number of end-of-life airplanes is anticipated to research 12000 to 14000 in ca. two decades. Final safe and proper disposal of end-of-life aircrafts is recongized as a great environmental concern in many developed countries The main objective of this research was to evaluate the curent situation of waste management in aviation industry in Iran as well as examining the appropriate strategies for management of end-of-life aircrafts, emphasizing on aircraft waste recycling and its enviro-economic impacts. The current situation of the Iran’s air fleet has been investigated in this context followed by evaluation of the amount of recyclable aluminum from end-of-life aircrafts. Energy saving and carbon fotprint reduction as a result of aircraft recycling as well as its economic benefits were deterimned. Results indicated that more than 157358 Giga Joule could be saved through proper management of end-of-life aircrafts in Iran. In addition, carbon dioxide emission from this sector can be reduced by more than 12539 ton and financial benefit of 194830064000 Rials would be achieved by recycling of aluminum from end-of-life aircrafts of Iran aviation fleet. Obtained results quantitatively demonstrated significant environmental and economical benefits from proper management of aircraft wastes in aviation industry suggesting serious planning and promotion of recycling programs for end-of-life aircrafts in Iran.
