Abstract :
    Among the most important technological advances of recent decades, we can mention the progress of electronic chips and microprocessors industry, and perhaps the most important technological achievements and human advances in the last century have been in the field of this industry and its related side cases. Electronic waste (E-waste) includes obsolete electrical or electronic devices. Recycling of electronic waste is an important issue in terms of protecting resources and the environment. Currently, nearly 1.3 billion tons of waste are produced worldwide annually, which is expected to increase to 4.3 billion tons per year by 2025. It is predicted that the generation of e-waste from old computers will increase by 500% within a decade, and in 2020, compared to 2007, there will be almost 18 times more discarded mobile phones. Knowing and understanding the different components of electronic waste helps in their effective recycling. Advanced electronic equipment contains approximately 60 different components, including valuable and hazardous materials. The most important valuable components of electrical waste are printed circuit boards (PCBs), which contain many dangerous substances in addition to precious metals. In order to prevent human and environmental poisoning, it is necessary to analyze the characteristics and composition of different materials in electronic waste and determine how to re-manage them through healthy environmental processes.
