Chapter Content
It is estimated that 75% of electronic items are stored due to uncertainty of how to manage it. These electronic junks lie unattended in houses, offices, warehouses etc. and normally mixed with household wastes, which are finally disposed off at landfills. This necessitates implementable management measures.
Detailed Explanation
A significant amount of electronic waste (e-waste) remains unaddressed, with 75% of electronic items being stored because people are unsure about how to dispose of them. This results in accumulation in various places like homes and offices, eventually leading to these items getting mixed with regular waste and ending up in landfills. Therefore, effective management strategies are required to handle e-waste responsibly.
Examples & Analogies
Think of e-waste like old clothes or toys that you don't use anymore but hang onto because you’re unsure of how to get rid of them. Instead of just piling them up in the closet (like e-waste piling up in homes), we need a systematic way to recycle or donate them.
Starting Management at Source

Chapter Content
In industries, management of e-waste should begin at the point of generation. This can be done by waste minimization techniques and by sustainable product design.
Detailed Explanation
E-waste management effectively starts where it is created—in the industries that produce electronic goods. Companies can implement waste minimization techniques and design products in a way that results in less waste. This proactive approach helps reduce the overall amount of e-waste generated.
Examples & Analogies
Just like a baker who measures ingredients carefully to avoid leftover dough, industries too can monitor and manage their resource use to prevent producing extra waste.
