Introduction
What is recycling?
 Recycling is to pass a substance through a system that
enables that substance to be reused. This is done to
reduce the use of raw materials that would have been
used.
 It generally reduces waste.

History of Recycling
 In pre-industrial times, evidence of scrap bronze and
other metals collected for reuse.
 In Britain dust and ash was collected by 'dustmen' and
used in brick making.
 In 1813, Benjamin Law developed the process of
turning rags into 'shoddy' and 'mungo' wool in Batley,
Yorkshire

Contd.
 The recycling movement began in the early 1960s .
Environmentalist believed that Americans were
wasting minerals, fuels, water, and trees, some of the
worlds most valuable resources
 In response to the waste outbreak, environmentalist
began to develop conservation methods to prevent the
inevitable

Recyclable & Non Recyclable
Materials
Recyclable Non Recyclable
Metal Containers (Aluminum, steel
and tin cans )
Non recyclable paper (Foil-coatings
or glitter, photographic film)
Paper milk and juice cartons Treated or contaminated wood
(Sheetrock or window glass)
Colored or clear glass (Jars, bottles
etc )
Non recyclable plastic consumer
items ( Dishware, vinyl, disposable
diapers, toys)
Plastics ( Bottles) Non recyclable glass ( Window
glass, mirrors)
Mixed Paper (Newspaper,
magazines)
Other waste (Ashes, soil, animal
feces )

How Recycling Impacts on
Environment
Recycling reduces landfill
Non-biodegradable
products remain in
landfill sites for centuries
7

How Recycling Impacts on
Environment (Contd.)
Recycling saves energy
Manufacturing items
from new sources uses
more energy
Energy saved in recycling
a glass bottle powers a
PC for 25 minutes
8

How Recycling Impacts on
Environment (Contd.)
Recycling improves the
soil
Organic waste is rich in
carbon, nitrogen and
other nutrients which
enrich soil
9

How Recycling Impacts on
Environment (Contd.)
 Recycling decreases pollution
 Recycling conserves natural resources
 Recycling reduces costs
10

Recycling in Case of Bangladesh
 Dhaka City Corporation
collects in excess of
50,000 tons of plastic
waste annually
 The plastic recycling
industries save the city
from being submerged in
a sea of plastic.
11

Benefits of Recycling
 Recycling saves resources
 Recycling saves energy
 Recycling helps protecting the environment
 Recycling reduces incineration
 Recycling reduces pollution
 Recycling saves money
12

Drawbacks of Recycling
 Methane gas produced during recycling if allowed to
seep out can lead to global warming
 Operating and maintaining recycling equipment is
cost intensive
 Poor management of recycling sites can lead to the
creation of unhygienic conditions
13

Waste Management in Bangladesh
 Major sectors of waste
14

Waste Management in Bangladesh
(Contd.)
 Various new projects have been adopted in
collaboration with the Asian Development Bank
(ADB), Japan International Cooperation Agency (Jica)
 DSCC Mayor Sayeed Khokon had disclosed a plan to
set up nearly 12,000 bins with Tk 8,000 on average
spent for each bin
15

Few Examples Of Good Practices
 Source Separation of Waste at Uttara Model Town
(Sector 5)
 Composting of Waste in Slums
 Battery buy back by Raheem Afroze for recycling
 A Tk 21 cr. waste management project, financed by
Bangladesh Climate Change Trust Fund
16

Our Ideas
 We can spread awareness among people about the
good effects of recycling
 We can gather people from our neighborhood on
week offs and collectively make efforts to collect useful
garbage
 We must use bins every time we dump waste material
 We must use internet to know more and about
recycling
17

Recycling is The Way of New Era
 Once you make the choice to recycle
 And stick to that choice everyday
 Recycling becomes second nature – a way of life
18

Conclusion
So, lets start recycling from today for a
better tomorrow
