  • E-Waste Management

    "E-waste" is a popular informal name for electronic products nearing the end of their "useful life. "E-wastes are considered dangerous as certain components of some electronic products contain materials that are hazardous depending on their condition and density. Electronics have been cited as a leading source of mercury in municipal waste. The largest source of cadmium in municipal waste is rechargeable nickel-cadmium (NiCd) batteries commonly found in laptops cell phones and cameras. In addition brominated flame-retardants are commonly added to plastics used in electronics.
