SOLID WASTE MANAGEMENT

2. In a nutshell, “solid waste can be regarded as refuse
or waste from any kind of source”.
Solid waste manaement is the collection,transportation
and disposal of solid waste in a systematic,economic
and hygenic manner.

3. FROM WHERE THIS COMES??

5. EFFECTS OF WASTE IF NOT PROPERLY MANAGED
Affects our health
Affects our socio-economic condition
Affects our coastal and marine environment
Affects our climate

6. SOLID WASTE MANAGEMENT
Waste management refers to the activities connected
with the collection and disposal of waste.
Waste management comprises the following activities:
waste collection
Waste transportation
Waste seggregation
Waste recycling
Waste disposal
Waste minimisation and control

8. Reduce, Reuse and Recycle
Method of waste reduction, waste reuse and recycling are the
preferred options when managing waste.
Waste reduction and reuse are both methods of waste prevention.
They eliminate the production of waste at the source of usual
generation and reduce the demands for large scale treatment
Donate or exchange
Recycling refers to the removal of items from the waste stream to
be used as raw materials in the manufacture of new products.

9. BENEFITS OF RECYCLING
Resource conservation
Pollution reduction
- crushed glass reduces the energy required to
manufacturing of new glass by 50%
- Over 60% aluminium cans are recycled.
Saves money, resources and land.
Encourages individual responsibility.

10. WASTE COLLECTION
TYPES
Curb
Alley
Set out and set back
Backyard collection

11. WASTE DISPOSAL/TREATMENT
with different types of waste, different treatment methods are applied.
These treatment process has been listed below:
-open dumps
-Landfills
-Composting
-Inceneration
-Pyrolysis

12. OPEN DUMPS
Low lying uncovered areas.
Waste is untreated and seggregated.
LANDFILLING
1.Sanitary landfills
Placed in areas where land features act as a natural buffer
Bottom covered with clay soil or plastic
Recover energy – anaerobic decomposition- methane &CO2-LFG
system - heat&electricity
2.Bioreactor landfills
Used enhanced microbiological process
Constant addition of liquid- added recyclating landfill leachate.

13. BIOLOGICAL WASTE TREATMENT
COMPOSTING
It is a process in which organic matter of solid waste is
decompossed and converted to humus and mineral compounds .
End product is compost – used as fertiliser
THERMAL TREATMENT
PYROLYSIS
Thermal degradation of waste in the absence of air.
Decompose organic waste using high temp.
Gas ,liquid and chars are the byproduct.

14. INCINERATION
 Waste treatment process that involves the combustion of solid
waste at 1000c.
 By products are ash, gas and heat

15. Challenges to solid waste management
Disposal of e-waste
Acid bath
Incinerator
Recycling
Disposal of sanitary napkins
Sanitary pad manufacturing unit
reusable napkins
sanitary napkin incinerators- ‘Ashudhdhinashak’-shyamsunder

17. CONCLUSION
As a result of all it was presented, we can conclude that :
Composting, pyrolysis and incineration are waste minimization
technologies.
Thermal waste treatment technologies allow to obtain volume
reduction and energy recovery.
Composting is a natural process and this makes it an ecological
technology for treatment of decomposable wastes.
