3. INTRODUCTION
The term “ Plastic” includes materials composed of various elements such as carbon,
hydrogen, nitrogen and sulfur.
Plastics are macro molecules, formed by polymerization & having the ability to be shaped by
the application of reasonable amount of heat & pressure or any other form of force.
It is one of the few new chemical material which pose environmental problem.
Polyethylene, polyvinyl chloride and polystyrene is largely used in the manufacturing of
plastic.
Plastics are made from non-biodegradable-harmful materials and land filling them
would increase the volume of the waste and pollute ground water and may hider its
movement.
Therefore Plastic waste has to be utilized and recycled efficiently. This paper
provides a review of product of Plastic bricks which can effectively use plastic
waste as an alternating material.
4. TYPES OF PLASTIC MATERILS
Plastics, depending on their physical properties, may be classified as thermoplastic
or thermosetting plastic materials
Thermoplastic materials can be formed into desired shapes under heat & pressure
and be come solids on cooling. If they are subjected to te same conditions of heat
& pressure , they can be remolded.
Thermosetting materials which once shaped can not be softened/ remolded by the
application of heat.
Out of total uses of plastic , 80% are thermoplastic & 20% are thermosetting.
6. ENVIROMENTAL ISSUES ON DISPOSAL OF PLASTIC
WASTE
Indiscriminate plastic waste disposal on land makes the land infertile due to its impervious
nature.
Burning of plastic generate toxic emissions such as carbon monoxide, chlorine & hydrocarbon
Plastic bags litter the landscape and kill animals.
7. Statement of Problem
The Organic component of Solid Waste may not be too much of a problem since that is
biodegradable.
However, the Plastic Waste component of Solid Waste poses a lot of problem in our
environment because it is non-biodegradable and therefore can stay in the environment for a
considerable length of time causing all sorts of problems.
Currently, the disposal of plastic waste is by incineration and landfill in Ethiopia, which is a
treat to the environment.
The former is not environmentally friendly and sustainable since this may release carbon
dioxide, a major contributor to global warming (greenhouse effect).
And the latter is not also desirable since plastic is non-degradable.
Most of gutters in Ethiopia are currently choked with plastic waste and this has resulted in
floods, loss of property and also causing high rate of malaria and cholera .
Recycling of plastic waste seems to be the best solution to plastic waste menace.
8. Objectives
The main objective of this project is to produce plastic Sand Based Tiles
(Pavement) from plastic waste .
Specific Objective
To alter the current waste management system and create an efficient way
of utilizing waste plastics.
To Minimize and reuse generation of waste plastic on the land and water
to avoid land and water degradation and consequent pollution hazard.
To produce cost-effective materials which a common person can afford
easily.
To Create a job opportunity for the unemployed youth
9. Significance of the Study
Utilizing plastic waste for the production of eco- friendly, strong, durable,
stable, waterproof, lightweight, good soundness and attractive bricks and
tiles.
Playing a significant role to changing waste management system of our
country, so as to modify the linear economy to circular economy.
11. Methodology
Waste plastic Collection.
Batching and characterization of the waste
Washing and Chopping the waste plastic.
Melting the waste
Sieve the sand.
Mixing
Molding
Curing.
13. Characterization
Compressive Strength Test
This test is done to know the compressive strength of the brick and
pavement.
It is also called the crushing strength of brick and pavement
In this test, a brick specimen is put on compressive strength testing
machine and the pressure will applied at a constant rate till it breaks.
14. Water Absorption Test
In this test the bricks and pavement first weighted in dry condition and they
are immersed in water for 24hours.
The bricks or pavements to be tested should be dry in an oven at a
temperature of 105oC to 115oC till it attains constant weight
Crushing test
This is the main test conducted to test the suitability of the brick for
construction work. This test is executed with the help of compression
testing machine.
15. Conclusion
Using all these discussion it can be concluded
that:
The non-biodegradable properties of plastic waste are able to assist the
long-term workings of construction materials.
The utilization of plastic waste is anticipated to reduce the cost of pavement
construction. This will improve the economic and environmental
significance in underdeveloped and developing countries
Plastic waste management has assumed great significance in view of the
urbanization activities.
