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
