چکیده

در عصر اقتصاد دیجیتال، میزان استفاده از وسایل الکترونیکی و به تبع آن ضایعات الکترونیکی افزایش یافته است بطوریکه ضایعات الکترونیکی سریعترین رشد را در میان زباله‌ها در جهان دارد. همچنین این ضایعات مانند زباله‌های دیگر دارای اثر مخرب زیست محیطی می‌باشد. لذا کنترل ضایعات الکترونیکی و برنامه‌ریزی جهت بازیافت آن به عنوان یک معضل مدیریتی و محیط زیستی در سطح ملی و جهانی مطرح است. در این پژوهش با استفاده از رویکرد پویایی‌شناسی سیستم‌ها و با استفاده از مدل‌سازی اسنادی و بررسی ادبیات موضوع به طراحی مدل پویایی‌شناسی سیستم در جهت شناسایی ساختار حاکم بر ایجاد ضایعات الکترونیکی و بازیافت آن و پیش‌بینی میزان ضایعات و ظرفیت مورد نیاز برای بازیافت آن پرداخته شده است. نتایج حاصل از مدل نشان داد که هر چند میزان ضایعات و به تبع آن بازیافت آن دارای رشد است اما این رشد با محدودیت مواجهه شده است. با این حال صنایع بازیافتی دارای درآمد روبه افزایش می‌باشند.

چکیده [English]

In the age of digital economy, the use of electronic devices and consequently e-waste has increased so that e-waste is considered as the fastest growing waste in the world. Also, these wastes, like other wastes, have a detrimental effect on the environment. Therefore, control of e-waste and planning for its recycling is a management problem at the national, global and environmental levels. In this research, using the system dynamics approach and using document model building (DMB) and reviewing the literature, the dynamics model is designed to identify the structure governing the generation of e-waste and its recycling and predict the amount of e-waste and the capacity required for its recycling. The results of the model showed that although the amount of waste and consequently its recycling has increased, this growth is limited and is S-shaped. However, recycling industries have increased revenues.
