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

Material Recovery Facil it iesRecod i ng Purposes
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
