4. OBJECTIVES OF SOLID WASTE MANAGEMENT
• Minimize water
generation
• Maximize the
collection efficiency
of waste
5. OBJECTIVES OF SOLID WASTE MANAGEMENT
• Reduce the volume of waste
requiring disposal and maximize
the economic value of waste
• Develop and adapt
environmentally sound treatment
and disposal methods
6. WASTE MANAGEMENT
Should ideally consist of
environmentally acceptable
waste management practices
6
Provide protection of human
health and the environment
8. WASTE PREVENTION
• Avoiding the potential for waste
generation.
• Develop and adapt
environmentally sound treatment
and disposal methods
9. WASTE MINIMIZATION
Reduce the quantities of waste
requiring disposal
• Reducing waste at source
• Reusing materials
• Recycling waste materials
• Reducing the use of toxic or harmful
materials
10. WASTE RE-USE
The reuse of discarded items
without additional processing
• In manufacturing industry
• In office or household terms
12. CLASSIFICATION OF SOLID WASTE
12
BASED ON THEIR SOURCES OF
ORGIN
• Residential wastes
• Commercial wastes
• Institutional wastes
• Municipal wastes
• Industrial wastes
• Agricultural wastes
13. CLASSIFICATION OF SOLID WASTE
13
BASED ON PYSICAL NATURE
• Garbage
• Ashes
• Combustible and non-combustible
wastes
• Demolition and construction
wastes
• Hazardous wastes
18. METHOD
• Open dumps
• Landfills
• Anaerobic Digestion
• Composting
18
For the treatment of
the solid waste
• Vermicomposting
• Encapsulation
• Incineration
19. OPEN DUMPS
• Uncovered areas that
are used to dump solid
waste of all kinds
• The waste is untreated
and not segregated
19
20. LANDFILLS
• Also known as a dump
or tip
• A site for disposal of
waste materials by
burial
20
21. SANITARY LANDFILLS
• Designed to greatly
reduce or eliminate the
risks that waste
disposal may pose to
the public health and
environmental quality.
21
23. ANAEROBIC DIGESTION
• Regulated version of the
natural events of landfill
• Carried out in large
fermented tanks
• Controlled release of
methane-rich biogas
23
24. ANAEROBIC DIGESTION
4 main groups of bacteria
involved
• Hyrdrolytic fermentive bacteria
• Acetogenic bacteria
• Acidogenic bacteria
• Methnogenic bacteria
24
28. ENCAPSULATION
Solid particulate material is
coated with thermosetting
resin which is compressed to
form a rigid core.
• Microencapsulation
• Macroencapsulation
28
29. INCINERATION
Burning of the waste at a
temperature of 1000˚C +/-
100 in the presence of
oxygen to eliminate all odors
and to ensure good
combustion
29
30. MANAGEMENT OF MEDICAL SOLID WASTE
• Includes both non-hazardous
and hazardous waste
constituents
• Treatment Options:
Incineration
Sanitary Landfills
30
34. MANAGEMENT OF ELECTRONIC WASTE
Electronic waste can be toxic if
processed improperly.
Treatment options:
• Encapsulation
• Incineration
• Sanitary Landfill
34
35. “
FACTORS AFFECTING SOLID WASTE
MANAGEMENT
35
• Per capita income and status
• Climate and Percentage
moisture
• Systemic growth of city
• Status of the municipality
• Resources available
36. CONCLUSION
Solid waste management is the process of
removal of solid waste in such manner that it does
not cause any problem to the environment and the
living organisms as well. It is done through
different methods as per the category of the solid
waste
