[ 5 ] - ارزیابی نشت هیدروکربن های آروماتیک چند حلقه ای از سایت های آلوده به ترکیبات نفتی

چکیده زمینه و هدف: هیدروکربن های آروماتیک چند حلقه ای[1] از مهم ترین آلاینده های محیط می باشند که نشت آن ها از خاک به منابع آب زیرزمینی یکی از مهم ترین نگرانیهای محیط زیستی می باشد. با توجه به حجم بالای فعالیت های نفتی، سایت های متعددی در کشور آلوده به ترکیبات نفتی شده اند. تصمیم گیری در خصوص پالایش یا عدم پالایش خاک های آلوده به مواد نفتی با توجه به هزینه های بسیار بالای پالایش خاک نیازمند ...

[ 6 ] - Application of Life Cycle Assessment for Techno-Economic Evaluation of Rural Solid Waste Management Strategies: Significance of CO2 Emission Control from Waste Management Sector in Abyaneh Village, Isfahan Province

Waste disposal in the current situation, which quantity and variety of waste are increasing, needs not only effective management principles but also depends on environmentally-friendly methods to put as less environmental footprint as possible. This study aims to assess the energy consumption, emission of greenhouse gases and air pollutants which normally produce during various waste management...

[ 7 ] - Capability of Reused Waste from Aluminum Industry (Red Mud) in Iran to Improve Compressive Strength of Loose Soil

Jajarm Alumina Plant, the only Alumina powder producer in Iran, generates 500,000 tons of red mud annually. The commonest method for final disposal of red mud in Iran is Tailing dam which is neither cost-effective nor environmentally-friendly. The main objective of this study is to evaluate the possibility of red mud recovery to be used for stabilization of loose soils. Red mud samples have bee...

[ 8 ] - Modeling of solid waste collection and transportation in metropolitan areas using WAGS model: implication of CO2 emission and external costs

Annually more than 80% of the overall budget of the uran solid waste management system in Iran is allotted to collection and transportation of the solid wastes. The main objective of the current study is to evaluate the external costs associated with solid waste collection, transfer, and transportation in Tehran for the period of 2018 to 2032 based on the current situation. Waste guidance syste...

[ 10 ] - مدیریت هواپیماهای مستعمل در ایران با رویکرد حفظ منابع و کاهش ردپای کربن

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 ...

[ 11 ] - Comparative Evaluation of Unmitigated Options for Solid Waste Transfer Stations in North East of Tehran Using Rapid Impact Assessment Matrix and Iranian Leopold Matrix

The current situation of world’s environmental issues, indicates that not only the man-made environmental damages have not been diminished, but also has given rise to more acute issues such as water and soil pollution, biodiversity loss, ozone depletion, greenhouse phenomena, etc. One of the most prominent effects of urban development on environmental problems caused by solid waste generated in...

[ 12 ] - Environmental and Economic Evaluation of Municipal Solid Waste Management using WAGS Model – Air Pollutant Emission and Fuel Economy in Waste Collection Sector

Solid waste collection, transfer and transportation (SWCTT) is a fundamental component of solid waste management systems that contributes to both the costs and environmental emissions associated with managing solid waste. The objective of this study is to project the fuel consumption and fuel costs of SWCTT in Tehran from 2018 to 2032. A further objective is to evaluate the air pollutant emissi...
