GOOD AFTERNOON TO ALL !!

Methods of Waste Disposal: Reuse, Recovery, Recycle

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

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

Gift bags

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

WHAT DO THE 3 ARROWS STAND FOR?
