• Mining wastes

• Dead animals

Method of Disposal of Solid waste

1. Land filling

2. Incineration

3. Vermicomposting

LandFilling

‘Burying’ of waste.

PROBLEMS:

Air pollution

Generation of liquid leachate.

Harmful Gas.

Incineration

‘Burning’ of Waste.

PROBLEMS:

Emission of dangerous fumes.

Incinerators require a source of energy to start.

Vermicomposting  ’Composting’ using

various ‘Worms.’

Manages

Bio-Degradable waste.

Highly economical.

Effects of Improper Solid Waste Disposal

Air pollution

Groundwater Contamination

Stagnant water for breeding insects.

Land can get degraded and poisoned

The government should work to invest on proper SWD facilities, like sanitary landfills and incineration factories.

They should also increase awareness throughout all sectors of society

Solution to Improper Solid waste Disposal

Present Condition Disposal of solid waste in Dhaka According to Dhaka City Corporation (1999), six dumping sites have already been abandoned after filling to their capacities. These sites are:

(1) Kulsi,

(2) Chalkbari-Mirpur,

(3) Gabtoli-Mirpur,

(4) Lalbagh Shosan Ghat,

(5) Mugdapara

(6) Jatrabari.

But at present almost all the wastes go to Matuail. Matuail landfill covers about 52 acres where 32 acres.

Conclusion Dhaka City Corporation (DCC) is unable to offer the

desired level of services with the existing capacity and trend of waste management.

Projection of future generation rate indicates that by the year 2020 it may exceed 30 thousand tons/day, which in turn will require over 200 acres/yr of landfill area

Experts have suggested that a community based solid waste management possible way out of the current inefficient system.
