E-waste, which includes discarded electronic devices, is a rapidly growing global problem, producing around 50 million tons annually, with only 15-20% being recycled. Environmental hazards include toxic substances like mercury and lead, which pose serious health risks and environmental damage. Effective management strategies involve waste minimization techniques, inventory control, and sustainable product design to mitigate the impact of e-waste.

1. E-WASTE CHALLENGES

2. INTRODUCTION
 Electrical waste or e-waste is any broken or unwanted
electrical or electronic appliances
 E-waste includes computers , entertainment
electronics ,mobile phones and other items that have
been discarded by their original users

3. CAUSES
 E-WASTE is the most rapidly growing waste problem
in the world
 It is crisis of not quantity alone but also a crisis born
from toxics ingredients ,posing a threat to the
occupational health as well as the environment

4. A GLOBEL CHALLENGE
 An estimated 50 million tons of e-waste are produced
 The USA discarded 30 million computers and 100
million phones , china produces about 2.3 million tons
of e-waste
 The environmental protection agency estimates that
only 15-20% of e-waste is recycled the rest of the e-
waste go directly to the landfills

7. ENVIRONMENTAL IMPACTS OF
ELECTRONIC WASTE
MERCURY:
 Found in fluorescent tubes causes environmental
effects in animals include death , reduced fertility
,slower growth and development
 There is also evidence of DNA breaks which can
increase the likelihood of developing cancer

8. ENVIRONMENTAL IMPACTS OF
ELECTRONIC WASTE
LEAD:
 Found of solder , CRT monitor glass ,lead-acid
batteries ,some formulations of PVC .
 Adverse effects of lead exposure include impaired
cognitive function , behavioral disturbance ,attention
deficits , hyperactivity and lower IQ

11. E-WASTE MANAGEMENTS
Waste minimization techniques inn industries involves
adopting:
 Inventory management
 Production-process modification
 Volume reduction
 Recovery and reuse

12. INVENTORY MANAGEMENT
Proper control over the materials used in the
manufacturing process is important way to reduce waste
generation
This can be done in two ways:
 Establishing material-purchase review and control
procedures
 Inventory tracking system

13. RESPONSIBILITY AND ROLE OF
INDUSTRIES
 Use label materials to assist in recycling
 Standardize components for easy disassembly
 Create computer components and peripherals of bio-
degradable materials
 Encourage
 Promote
 Require green procurement for corporate buyers

14. SUSTAINABLE PRODUCT DESING
 Minimization of hazardous wastes should be at
product design stage itself keeping in mind the
following factors
 Rethink the product design
 Use of renewable materials and energy
EG:
use of bio-based plastics
