The document discusses methods for waste disposal and management, focusing on reducing, reusing, and recycling (the 3 Rs). It defines recycling as processing used materials into new products, which prevents waste and reduces environmental impacts. It provides examples of materials that can be recycled like glass, paper, plastics, and metals. It also discusses ways to reduce consumption and reuse items to manage waste, along with methods for collecting recyclables. The overall message is that reducing, reusing, and recycling are important components of modern waste reduction.

1. NARAYANA E-PROJECTS 2013

2. THIS IS LIVENSON
FROM 8TH E-TECHNO

3. Methods of Waste Disposal:
Reuse, Recovery, Recycle

4. Due to pollution soil and air became
contaminated……….
Which Results many infectious diseases
and disposal problems…
And the only remedy that
can be adapt is giving
importance to
Reducing the use
and
The disposal of waste

6. RECYCLING MEANS THE PROCESSING OF USED
MATERIALS OR WASTE INTO NEW PRODUCT!
KEY COMPONENT OF MODERN WASTE REDUCTION
&
THE THIRD COMPONENT OF WASTE HIERARCHY

7.  Prevents waste of potentially used materials
 Reduce the consumption of fresh raw
materials
 Reduce energy usage
 Reduce air & water pollution
 Recycling of a material would produce a
fresh supply of the same material
eg: Paper recycling

8. Glass
Paper
Plastics
Metals
Textiles

9. Biodegradable Materials
Industrial Materials

10. Drop off centre's
Buy back centre's
Curbside collection

11. REUSE

12. REUSE
This includes conventional reuse
where the item is used again for
the same function, and new-life
reuse where it is used for a new
function.
To reuse is to use an item more
than once.

13. Paper
Rubber bands
Buttons
Paper clips
Empty food containers
Water bottles
Card board boxes
Gift bags

15. Includes any technique or method of minimizing the input of energy
to an overall system by the exchange of energy from one sub-system
of the overall system with another.
The energy can be in any form in either subsystem, but most energy
recovery systems exchange thermal energy in either sensible or latent
form.

16. Heat recovery is implemented in heat sources
Regenerative brake
Active pressure reduction systems

17. REDUCE
REDUCTION MEANS TO MAKE
SOMETHING SMALLER
USE SOMETHING LESS OFTEN

18. How to Reduce ?
 Do I really want this item?
 How long will the item will last?
 Can the item be reused after I am
finished with it?
 Is the item made from recycled
materials?
 Is the item recyclable?
 How is the item packaged?
 Do I need a bag to transport the item?

19. WHAT DO THE 3 ARROWS
STANDthe Material
FOR?
Collection of Recyclables
Manufacturing of
Buy Recycled Products

20. Practice the
3 R’s of Management
Reduce
Reuse
Recycle
