This document discusses waste management and e-waste. It notes that organic waste is the purest form of waste available and explores various methods for handling organic waste like incineration, waste to energy through processes like pyrolysis and gasification, and anaerobic digestion. The document also discusses the problem of e-waste, noting that 50 million tons are produced annually and it contains hazardous materials. It explores solutions for e-waste like inventory management, volume reduction to remove hazardous materials, and recovery and reuse of materials either on-site or off-site. The best long term solution identified is creating more public awareness about proper waste handling and disposal.

1. Waste Management
Leading the way to the future by utilizing what we are leaving
behind
By-Arjun Krishan Mohan
Swami Vivekanand Institute of
Engineering and Technology

2. Why focus on waste?
See any difference?

4. Waste Generated by Man
•Organic waste is
the purest form
of waste available.
•We all are finding
ways of disposing
off the other
waste materials
•But why dispose
them?

5. Cradle to Cradle

6. Incineration
• Why would the organic waste need
incineration?
• By Products?

7. Waste To Energy
•Pyrolysis
•Gasification
•Mechanical
biological treatment
•Fermentation
•Anaerobic digestion
By products ?
Anaerobic
digestion
Fermentation
Mechanical
biological
treatment
Pyrolysis
Gasification

8. Do We Know
Everything?
• 65% of its population is 35 or under, and half
the country's population of 1.25 billion
people is under 25 years of age.
• 2,31,89,111 Computers
• . 53.2% – have a mobile

9. What is E-Waste?
• Electronic waste describes discarded electrical
or electronic devices.
• An estimated 50 million tons of E-waste are
produced each year
• Could rise by 500 percent in India(10 years)

10. The Problem
• Electrical waste contains hazardous, valuable
and scarce materials. Up to 60 elements
• United States, an estimated 70% of heavy
metals from discarded electronics(Eg. Lead,
cadmium, copper, nickel)
• developing nations -"dumping grounds for e-waste”
China(e-waste) annually= 2.3+3=5.3 million
tons

11. The Solution
• Inventory Management
• Volume Reduction,
• Recovery and Reuse.
• Alternative bulk system
• Hewlett-Packard product
recycling solutions
Pre
Post

12. Inventory Management,
Hazardous?
Material
Alternative?
Reduction?
As needed
basis (time)

13. Volume Reduction,
To remove the
hazardous portion
from the non
hazardous portion
Source
Segregation
Waste
Concentration

14. Recovery and Reuse.
Waste can be recovered
On Site -
Off Site-

15. An Easier Solution?
Citizens
Responsibility
Government
Industries
Researchers

16. The BEST Solution
Awareness

17. Mother nature’s gift is in our hand
Lets make it a better place
Before its too late
Come lets take a stand.

18. THANK YOU!!!!!
