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 iesMRF Garbage Operat ion Flow Chart

• When the garbage truck

arrived at the MRF, all

residual waste,

recyclables and special

wastes, weighed and

recorded for

purposes

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
