What is disposal of solid waste
Solid Waste Disposal, disposal of normally solid or semisolid materials, resulting from human and animal activities, that are useless, unwanted, or hazardous.
• Garbage
• Rubbish
• Ashes
• Sewage-treatment solids
• 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.
Should also improve solid waste collection, by making sure they collect most of the waste and segregating it to make disposal easier.
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.
