Reduce Reuse Recycle

1. 3 R's Of Environment

2. Reduce
• Reduce: to make something smaller or use
less, resulting in a smaller amount of
waste.
• "Source reduction" is reducing waste
before you purchase it, or by purchasing
products that are not wasteful in their
packaging or use.
• A key part of waste "reduction" is
"conservation" / using natural resources
wisely, and using less than usual in order
to avoid waste.

3. How to Reduce
Buy products that can be reused
– We can reduce waste by using a
computer! Many newspapers and
magazines are online now. Instead of
buying the paper versions, you can find
them on the Internet.
– Save energy by turning off lights that you
are not using

4. Reuse
•Reuse: to use again or more than
once
•Reuse materials and items so that
they have longer life spans and don’t
get thrown away after the first use.
•Many items found around the home
can be used for different purposes.
•So before you throw those items
away, think about how they can be
reused.

5. How to Reuse
• Newspaper, cardboard and bubble wrap
Make useful packing material when moving house
or to store items.
• Old clothes
Can be made into other textile items such as
cushion covers.
• Scrap paper
Can be used to make notes and sketches.
• Rechargeable Batteries
Can be reused many times before they need
throwing away

6. Recycle
• Recycle: to convert materials/waste
into reusable material
• Recycling puts objects through a
process (it consume energy) that
allows them to be used again.

7. How to Recycle
• Example
Used plastic or metal objects can be
sold in scrap where they can be
recycled to create new usable
objects

8. Appropriate Technology
Technology should use less resources
and produce minimum waste
• Conservation of energy:-
• Conventional source of energy are
not renewable. Ex. Coal, Oil, Gas.
• This also cause emmision of green
house gases like CO2.
• It causes global warming.
• Fossil fuel must be used more
efficiently

9. Appropriate Technology
• Conservation of Water:-
• Potable water is very limited. There
are areas in world where water is
scare commodity
• Wastage of water is must be
prevented
• It is necessary for sustainable growth

10. Appropriate Technology
• Biological resources:-
• Steps should be taken to prevent
natural vegitation, biodiversity, forest.
• Lack of vegation will cause soil
erosion
• Disturbance in biodiversity will affect
ecological system

11. Appropriate Technology
• Reduction of pollution:-
• Uncontrolled use of fossil fuel causes
air pollution.
• Improper disposal of sewage water
will affect natural water resourses
and cause water pollution
• Solid waste cause soil pollution which
affect fertility of soil
• Hence reduction of pollution is
necessary

12. Appropriate Technology
• Consumerism:-
• People consume more than they
produce
• US has only 4.7% of worlds
population but consume 25% of
worlds resources
• Consumerism should be controlled
for sustainable development
