Due to pollution soil and air became contaminated……….
Which Results many infectious diseases and disposal problems…
INTRO…..
And the only remedy that can be adapt is giving importance to
Reducing the use
The disposal of waste
and
RECYCLE
RECYCLING MEANS THE PROCESSING OF USED MATERIALS OR WASTE INTO NEW PRODUCT!
RECYCLE
KEY COMPONENT OF MODERN WASTE REDUCTION
&
THE THIRD COMPONENT OF WASTE HIERARCHY
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
ADVANTAGES

REUSE
REUSEThis 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.
Materials to Reuse
Paper
Rubber bands
Buttons
Paper clips
Empty food containers
Water bottles
Card board boxes

ENERGY RECOVERY
ENERGY RECOVERY
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.
EXAMPLES
Heat recovery is implemented in heat sources
Regenerative brake
Active pressure reduction systems
REDUCTION MEANS TO MAKESOMETHING SMALLER
USE SOMETHING LESS OFTEN
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?
How to Reduce ?
Collection of Recyclables
Manufacturing of the Material
Buy Recycled Products
