E-WASTE MANAGEMENT E-WASTE MANAGEMENT

Introduction  E-waste is a popular, informal name for electronic products nearing the end of their “useful life”.This includes Computers and their peripherals Cell phones Photocopiers Digital cameras MP3 players.

Where does it come from?  Households and Small businesses  Large businesses, Institutions and Governments

How big is the problem?

Problem continues………  Electronic products often contain hazardous and toxic materials that pose environmental risks if they are land filled or incinerated.  Televisions, video and computer monitors use cathode ray tubes (CRTs), which have significant amounts of lead.  Printed circuit boards contain primarily plastic and copper, and most have small amounts of chromium, lead solder, nickel, and zinc.

Problem continues………  In addition, many electronic products have batteries that often contain nickel, cadmium, and other heavy metals. Relays and switches in electronics, especially older ones, may contain mercury.  Also, capacitors in some types of older and larger equipment that is now entering the waste stream may contain polychlorinated biphenyls (PCBs)

Effects of E-waste constituent on health Sl no: Sources of ewaste ConstituentHealth effects 1. Solder in printed circuit boards, glass panels and gaskets in computer monitors Lead (PB) Damage to central and peripheral nervous systems, blood systems and kidney damage. Affects brain development of children. 2. Chip resistors and semiconductors Cadmium (CD) Toxic irreversible effects on human health. Accumulates in kidney and liver. Causes neural damage.

Sl no:Sources of ewaste ConstituentHealth effects 3. Cabling and computer housing Plastics including PVC Burning produces dioxin. It causes Reproductive and developmental problems; Immune system damage; 4. Front panel of CRTsBarium (Ba) Short term exposure causes: Muscle weakness; Damage to heart, liver and spleen. 5. MotherboardBeryllium (Be) Carcinogenic (lung cancer) Inhalation of fumes and dust. Causes chronic beryllium disease or beryllicosis. Skin diseases such as warts.

 Landfill  Incineration  Reuse  Recycle  Export Where does it go?

Managing E-waste  Inventory management  Production process modification  Volume reduction  Recovery and reuse

E-waste managing…… Inventory management establishing material-purchase review control procedures and inventory tracking system

E-waste managing…… Production process modification Improved operating and maintenance procedures, Material change Process-equipment modification.

E-waste managing…… Volume reduction source segregation waste concentration

E-waste managing…… Recovery and reuse eliminate waste disposal costs reduce raw material costs provide income from a salable waste

Conclusion  E-waste management is a cycle that tackles the environmental impacts, social responsibilities and logistics. It is a complete process that includes workforce, transport medium and a good coordination with the government body
