1. Sustainable Waste
Management of Dhaka City

2. Introduction
Dhaka, the capital of Bangladesh, has a population of
approximately 12 million residents, including 3 million
in unincorporated areas. Managing waste is one of the
daunting problems in Dhaka. Some private firms and
NGOs are also engaged in cleaning waste. But so far,
these efforts failed to keep our city clean enough.
Most scientific, hygienic and cost effective waste
management system is to be evolved. This analysis
complies the present waste management system,
issues related potential for resource recovery and
development of public awareness regarding
sustainable waste management.
Dhaka City

4. ▪ The capital produces around 6000 tons of
domestic waste every day (Dhaka South
City Corporation (DSCC)-3,300 tons/day
and Dhaka North City Corporation (DNCC).
▪ About 2,700-2,800 tons/day), which is a
big problem for the City Corporations to
manage as DCC can lift only 50% of it.
▪ Around 9500 cleaners to care employed
lean 360 sq. kilometers of the city.

5. Classification of waste
Household waste
is generally classified as municipal
waste: Municipal solid waste
consists of household waste,
construction and demolition debris,
sanitation residue, and waste from
streets. This garbage is generated
mainly from residential and
commercial complexes. Again
Garbage is about four categories-
Organic waste, Toxic waste:,
Recyclable
Industrial waste as
hazardous waste: Industrial and
hospital waste is considered hazardous
as they may contain toxic substances.
Certain types of household waste are
also hazardous. Hazardous wastes
could be highly toxic to humans,
animals, and plants; are corrosive,
highly inflammable, or explosive; and
react when exposed to certain things
e.g. gases.
Biomedical waste
or hospital waste as infectious
waste: It may include wastes like
sharps, soiled waste, disposables,
anatomical waste, cultures,
discarded medicines, chemical
wastes etc. These are in the form
of disposable syringes, swabs,
bandages, body fluids, human
excreta etc. This waste is highly
infectious and can be a serious
threat to human health if not
managed in a scientific and
discriminate manner.

6. Present condition
of Waste
Management:
01
Primary collection and accumulation:
Around 9500 workers and some CBOs
doing the house-to-house collection and
then put those wastes into nearby
dustbins or containers using handcart.
02
03
Final disposal/Dumping: Wastes are then transferred
from secondary transfer station to central Waste
Disposal Centre. The DSCC’s one is at Matuail, Demra,
Dhaka and DNCC’s one (50 acres) is at Amin Bazar,
Dhaka.
04
Recycling: DCC has not yet any waste
recycling project but a few people of
interests have been doing this
recycling process.
Transportation: By using 158 open trucks and 35 compactor
trucks DCC have to collect waste from 850-950 open spots
along with 322-330 containers from about 170 routes in the
DSCC and about 240-245 in DNCC.

8. Consequences of
Running Management System
▪Open air dumping creates unhygienic and possess enormous threat to
the people.
▪Causes aesthetic problem and nuisance due to nauseating pungent
odor.
▪As all sorts of wastes are gathered together, it is very difficult to
separate the recyclable materials.
▪Hazardous and toxic wastes dumped in the landfills contaminate soil
and ground water.
▪Toxic and heavy metals are mixing into the food chain.

9. ▪Unauthorized and abandoned burning of waste at a existing
disposal site causes air pollution.
▪Gases are produced in the landfills through aerobic and
anaerobic decomposition of organic compounds, which are
threat to the environment, promotes spreading of diseases.
▪Chemical and oil spills contaminate water that kills water
floral-faunal species and other wildlife.

10. Our proposal for
Sustainable Waste Management

11. BIG CONCEPTOur proposal for
Sustainable Waste Management
▪ At present, Dhaka city is divided into two separate city corporations named
Dhaka North City Corporation (DNCC) and Dhaka South City Corporation (DSCC).
Both of these corporations manage the wastes of the whole city according to
Solid Waste Master Plan (2005) where some bins are used to collect all the
wastes from a certain area. However, this process cannot be appreciated as a
good example of sustainable waste management because in this process all sort
of wastes like organic, inorganic and hazardous wastes are being dumped in the
same way which is harmful for health and environment and emit more
greenhouse gases.

12. BIG CONCEPT
Our proposal for Sustainable Waste Management
▪ So, to improve the sustainability of the system, we propose to collect the wastes in two
separate bins where organic and inorganic wastes will be collected from household and
other sources of wastes. For this, public awareness building program is also proposed so
that people at home and other places can identify the difference between organic and
inorganic wastes and can dump them into different bins. Thus, a system will be developed
where all the household or municipal wastes will be dumped in two different ways. The
organic waste will be used further as raw materials of fertilizers by sending them to the
fertilizer industries and for producing food for domestic animals as well as it could be used
in the biogas plants by recycling in proper controlled processes. In this way the amount of
total wastes will be reduced and the rest of the inorganic wastes will be sent to the
selected dumping stations and where it will be easier to find out the recycled, renewable
and hazardous part of the inorganic solid waste

16. • Then from the remaining inorganic solid wastes,
the re-usable and recyclable products such as
polythene, plastic, rubber, glass and ceramic, e-
wastes etc will be separated for further use.
• In the next step, the non-renewable and other
wastes from industrial and biomedical wastes are
collected from respective areas will also be sent
for incineration.
• As the existing open dump incineration is much
hazardous, we propose to introduce closed system
known as Waste-To-Energy (WTE) plants which
are used by many developed and developing
countries of the world.
• Though this system is highly expensive, for the
sake of sustainability we should go for it right
away because it is the best possible way to manage
waste and it can also be helpful for producing
energy that we lack.

18. E-Waste

20. Conclusion:
Waste problem is one of the burning issues of Dhaka city right now. So in order to meet the goal
of sustainability we must take up a fruitful action as soon as possible. Towards that milestone we
have proposed a layout of sustainable waste management for Dhaka city under the master plan
of 2005.For this we have introduced the plan known as Waste-To-Energy (WTE) program. This
may cost a little bit more but the output will be many times greater. But this is the high time we
taken up an immediate action regarding this great problem rather than investing our valuable
revenue to less important sectors. As we know clean environment leads to a better life and
which will take us to our development goal, we want to say that this should be started from now
on, may be from our kitchen first. Before throwing a waste we must think about how we can
reuse it. Then we may separate the garbage’s to different waste bins for greater purposes as we
said before. However, all these actions will go in vein until we are aware by ourselves as well as
give proper education to the people of our surroundings to make the best use of waste bins, try
to produce wastes to the least, and dump wastes in a scientific way and thus we can hope to
have a beautiful Dhaka City which we all are dreaming.
