6. EFFECTS OF SOLID WASTE
On Human Health
If solid waste are not properly stored and collected but allowed to accumulate, they will create unsanitary conditions;
May lead to outbreak and spread of diseases like cholera, diarrhea, jaundice etc.;
In proper handling of solid waste is a health hazard for workers who come in direct contact with the waste.

7. EFFECTS OF SOLID WASTE (b) On the Environment
If not stored and collected will reduce the aesthetics;
If not stored and collected will clogged drains and cause flooding during heavy rain fall;
If not treated properly decomposition take place in the open and objectionable gases are released to the atmosphere.

8. ELEMENTS OF SWM Generation Storage Collection and Transportation
Material Recovery and Recycling
Disposal

9. GENERATION
When materials are identified as no longer being of value and are thrown away.
Things that affect quantity and type of materials that are thrown away:
Geographic location
Season of the year
Characteristics of population
Reuse and recycling
Public attitudes
Legislation or laws regarding restrictions on waste materials that can be disposed

16. DISPOSAL Methods Landfills Incineration Source reduction Composting
Recycling

18. DISPOSAL Each day garbage/trash is spread in thin layers
Sanitary Landfill
Each day garbage/trash is spread in thin layers
Compacted down
Covered with a soil layer
Graded for drainage
Sanitary landfills have largely replaced open dumps.

19. DISPOSAL Properly designed landfill will;
Prevent water infiltration and leaching of toxic fluids
(LEACHATE = a liquid that has passed through or emerged from solid waste and contains soluble, suspended, or miscible materials removed from such waste)
Prevent water pollution
Reduce Vermin and pests
Reduce smell, toxic gases and fire hazard

21. DISPOSAL INCINERATION (burning):
Significantly reduces the volume of garbage
Produces heat energy for generating electricity
Materials such as batteries, glass etc. are NOT suitable for incineration
Causes air pollution
Creates toxic ash and other solid waste
