Topic:Research proposal of solid waste managment

3. Executive summary
 The Japanese,through a combination of
public policy,private market condition,and
geographic necessity, practice integrated
municipal solid waste management,difined
in the u.s EPA decision makers guide to
solid waste management as:
 A practice of using several
alternative waste management techniques to
manage and dispose of specific components
of the municipal solid waste stream.waste
management alternatives include source
reduction,recycling,composting,energy
recovery,and landfilling.

4. Change the role of the
municipality of shanghai from
being a service provider to being
a service regulator and facilitator
by transferring the responsibility
for supplying
collection,treatment and disposal
services to social capital
participating organigation.
Objective

16. These are the following methods for disposal of the solid
waste.
• LAND FILLS
• INCINERATION
• BIOLOGICAL REPROCESSING
• RECYCLING
• OCEAN DUMPING
• PLASMA GASIFICATION
Methods of Disposal

17. LAND FILL
 It is the most traditional method of waste
disposal.
 Waste is directly dumped into disused quarries,
mining voids or borrow pits.
 Disposed waste is compacted and covered with
soil to prevent vermin and wind-blown litter.
Methods of Disposal

18. Advantages:
• Landfill site is a cheap waste
disposal option for the local
council.
• Jobs will be created for local
people.
• Lots of different types of waste
can be disposed of by landfill
in comparison to other waste
disposal methods.
• The gases given off by the
landfill site could be collected
and used for generating power.
Disadvantages:
• Dangerous gases are given off
from landfill sites that cause
local air pollution and
contribute to global warming.
• Local streams could become
polluted with toxins seeping
through the ground from the
landfill site.
• Once the site has been filled it
might not be able to be used
for redevelopment as it might
be too polluted.
Methods of Disposal

19. OCEAN DUMPING
 Ocean dumping is the dumping or placing of
materials in the ocean, often on the continental
shelf.
 A wide range of materials is involved, including
garbage, construction and demolition debris,
sewage sludge, dredge material, waste
chemicals, and nuclear waste.
 Sometime hazardous and nuclear waste are also
disposed but these are highly dangerous for
aquatic life and human life also.
Methods of Disposal

20. Advantages:
• Convenient
• Inexpensive
• Source of nutrients for fishes and
marine mammals.
• Vast amount of space is available.
• All type of wastes are disposed
Disadvantages:
• There are three main direct public
health risks from ocean dumping:
(1) occupational accidents,
injuries, and exposures
(2) exposure of the public to
hazardous or toxic materials
washed up on beach sand.
(3) human consumption of marine
organisms that have been
contaminated by ocean
disposal
• Highly dangerous for aquatic life.

21. BIOLOGICAL PROCESSING
 Materials such as plants, food scraps, and paper
products can be decomposed into the organic
matter.
 The organic matter that is produced from this type
of recycling can then be used for such things as
landscaping purpose or agricultural uses.
 Usually this method of recycling is done by putting
the materials in a container and let to stay there
until it decomposes.
Methods of Disposal

23. RECYCLING PROCESS
• COLLECTION: The first step required for
recycling is collecting recyclable materials from
communities. Today many major cities and larger
communities offer a curbside pick up service for
recyclable materials.
• SORTING: The second step involves processing
the recyclable materials. This includes sorting
the materials into groups, cleaning them and
getting them ready to be sold to manufacturers
who will turn the materials into new products.
Methods of Disposal

24. MANUFACTURING: It is the
third step in the recycling
process. The collected
material is sent to
industries those convert
them into new products.
PURCHASING: The last step
involves the purchasing of
recycled products. When
consumers purchase
products that have been
made with post consumer
material the recycling
process has been
completed and then can be
repeated.

25. Material Recovery Facilities
MRF Garbage Operation Flow Chart

26. • When the garbage truck
arrived at the MRF, all
residual waste,
recyclables and special
wastes, weighed and
recorded for
Documentation
purposes
Material Recovery Facilities
Recoding Purposes

27. The garbage collection
trucks at the material recovery
facility, were ready for the collection
in any routing schedule at the
barangay’s but a condition of “No
Segregation No Collection is the
policy” is implemented
The SWM enforcer
checked the garbage in the
household one hour before arrival
of the garbage truck to insure
the solid wastes are properly
segregated

Collection Management

28.  developing
environmentally friendly
methods of handling
garbage
 Inter government
cooperation
 Improve regional
cooperation
 Reduce the volume of
the solid waste stream
 Promoting
public/private
partnerships
