hazardous.
• Garbage
• Rubbish
• Ashes
• Sewage-treatment solids
• Mining wastes
• Dead animals

4. Method of Disposal of Solid waste
1. Land filling
2. Incineration
3. Vermicomposting

5. LandFilling
 ‘Burying’ of waste.
 PROBLEMS:
 Air pollution
 Generation of liquid leachate.
 Harmful Gas.

6. Incineration
 ‘Burning’ of Waste.
 PROBLEMS:
 Emission of dangerous fumes.
 Incinerators require a source of
energy to start.

7. Vermicomposting
 ’Composting’ using
various ‘Worms.’
 Manages
Bio-Degradable waste.
 Highly economical.

8. Effects of Improper Solid Waste Disposal
 Air pollution
 Groundwater Contamination
 Stagnant water for breeding insects.
 Land can get degraded and poisoned

Solution to Improper Solid waste Disposal

10. 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.

11. 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.
