Introduction
• What is a biodegradable object?
• It is an object that has the ability to break
down safely and quickly into the raw material
of nature and disappear into the environment.
• What is a non biodegradable object?
• It is an object made of components that will
not break down over time nor safely.
Activity1: Comparing biodegradable and
non biodegradable packing materials.
Part A
Objective:
• To set apart the biodegradable
polymer from the non
biodegradable polymer.
Procedure:
• Immerse the polymers in water.
Results:
• The biodegradable polymers
dissolved in water while the
other remained the same.
Activity 1: Comparing biodegradable and non
biodegradable packing materials.
Part B
What we did:
We brought two eggs
and we packed them in
bags, and we put the
polymers around them.
What we learnt:
 A biodegradable packing
material can be as
effective as a non
biodegradable packing
material in protecting an
egg from breaking.
Activity 2: Hunting for biodegradable objects
& Comparing.

Activity 3: Processing Biodegradable
Materials and Comparing Their
Mechanical Properties
Part A : Processing Biodegradable Materials .
• Objective: Making gelatin films
• Procedure: Process gelatin, a biodegradable material, into a gel and
into two films that vary in thickness and compressibility.
Activity 3: Processing Biodegradable
Materials and Comparing Their Mechanical
Properties
Part B: Comparing Their Mechanical Properties .
Discover how these materials vary in strength and compressibility.
Activity 4: Measuring the Degradation Rates of
Biodegradable Materials
• Objective: Test the effect of pH, temperature and
concentration on the degradation rates of the gel, films,
packing material (starch), and gelatin capsule.
• Result: Environmental conditions can affect the rate at which
a biodegradable material breaks down, environmental
conditions such as: the PH level, the concentration, the
temperature and the surface area.

Product Idea
The Green Plastic
• Introduction and Rationale:
• Our product is about investing in the unusable parts of the
palm trees which are the fronds and putting them through
some chemical procedures to make a biodegradable plastic
that will not affect the nature the way that the oil extracted
plastic does.
• Our goal
• We truly aim for a better future by protecting and
maintaining our nature in every way we can. By using the
green plastic, we are keeping our environment safe because
plastic is one of the most usable material yet it has a lot of
disadvantages, but not anymore.
The Green Plastic
Hypothesis:
•The Green Plastic is eco-friendly
METHODS
Part A: Manufacturing Bio-degradable
Plastic
• 1-Alkaline treatment: immerse the fibers
in a 2% NaOH aqueous for 24hr.
• 2-Wash fronds with normal tap water.
• 3-Cut the fronds into thin strips.
• 4- Wash them with distillated water.
• 5-Finaly put the frond in an oven for 2
hours on a 60 degree heat.
• 6- Cut the frond strips 1-2cm pieces.
• 7-Use the hot press machine to merge the
chemically treated natural fibers with
polystyrene waste.
Part B: Testing Mechanical Properties.
We made 3 samples:
• The first: only with polystyrene
waste.
• The second: polystyrene waste
with treated fibers placed
randomly.
• The third: polystyrene waste
with treated fibers placed with
orientation.
Dynamic Mechanical Analyzer
• Better mechanical response
with the samples including
fibers
• Fibers orientation exhibits
highest values of the elastic
modulus and less deformation.

•Samples are slightly dependent on
the frequency, means that all
samples were appropriate developed
structure with no defect.
•Fibers orientation exhibits highest
values of the elastic modulus.
Conclusion:
Oriented
fibers
considerably
reinforced
the
mechanical
properties of
the PS
matrix.
The Green Plastic
Results:
• The purpose of using The Green Plastic is to
decline the usage of the harmful plastic, so
no harm is left due to the usage of plastic.
• The usages of it are quite endless. The Green
Plastic could be used in many industrial
fields.
The Green Plastic
Recommendations:
• This product could be used in different
fields.
• We would really like to see further
investigations into the uses and
properties of this plastic.
• To enhance mechanical properties, use
additional chemical treatment such as
the peroxide treatment.
Conclusion
The green plastic will surely benefit our
environment by decomposing easily and
not leaving any harms behind.
Through Al-bairaq’s project we all gained :
• The team spirit, we stood by each other
throughout the whole time .
• How to analyze the experiments and how
to come out with an overall conclusion.
• The fundamentals of a basic research.

opportunity. To Qatar University and CAM, to our
school, to Ms.Hawa who stood with us throughout
the project’s period, and to the supportive team of
Al-bairaq who never let us down.

  • 2. Outline • Activity 1: Comparing biodegradable and non biodegradable packing material • Activity 2: Hunting for biodegradable objects & comparing. • Activity 3: Processing Biodegradable Materials and Comparing Their Mechanical Properties • Activity 4: Measuring the Degradation Rates of Biodegradable Materials. • Design Project : Designing a Medicine-Delivery Device • The Green Plastic
  • 3. Introduction • What is a biodegradable object? • It is an object that has the ability to break down safely and quickly into the raw material of nature and disappear into the environment. • What is a non biodegradable object? • It is an object made of components that will not break down over time nor safely.
  • 4. Activity1: Comparing biodegradable and non biodegradable packing materials. Part A Objective: • To set apart the biodegradable polymer from the non biodegradable polymer. Procedure: • Immerse the polymers in water. Results: • The biodegradable polymers dissolved in water while the other remained the same.
  • 5. Activity 1: Comparing biodegradable and non biodegradable packing materials. Part B What we did: We brought two eggs and we packed them in bags, and we put the polymers around them. What we learnt:  A biodegradable packing material can be as effective as a non biodegradable packing material in protecting an egg from breaking.
  • 6. Activity 2: Hunting for biodegradable objects & Comparing. • Biodegradable objects: • Non biodegradable objects: Examples of
  • 7. Activity 3: Processing Biodegradable Materials and Comparing Their Mechanical Properties Part A : Processing Biodegradable Materials . • Objective: Making gelatin films • Procedure: Process gelatin, a biodegradable material, into a gel and into two films that vary in thickness and compressibility.
  • 8. Activity 3: Processing Biodegradable Materials and Comparing Their Mechanical Properties Part B: Comparing Their Mechanical Properties . Discover how these materials vary in strength and compressibility.
  • 9. Activity 4: Measuring the Degradation Rates of Biodegradable Materials • Objective: Test the effect of pH, temperature and concentration on the degradation rates of the gel, films, packing material (starch), and gelatin capsule. • Result: Environmental conditions can affect the rate at which a biodegradable material breaks down, environmental conditions such as: the PH level, the concentration, the temperature and the surface area.

  • 13. Product Idea The Green Plastic • Introduction and Rationale: • Our product is about investing in the unusable parts of the palm trees which are the fronds and putting them through some chemical procedures to make a biodegradable plastic that will not affect the nature the way that the oil extracted plastic does. • Our goal • We truly aim for a better future by protecting and maintaining our nature in every way we can. By using the green plastic, we are keeping our environment safe because plastic is one of the most usable material yet it has a lot of disadvantages, but not anymore.
  • 14. The Green Plastic Hypothesis: •The Green Plastic is eco-friendly
  • 15. METHODS Part A: Manufacturing Bio-degradable Plastic • 1-Alkaline treatment: immerse the fibers in a 2% NaOH aqueous for 24hr. • 2-Wash fronds with normal tap water. • 3-Cut the fronds into thin strips. • 4- Wash them with distillated water. • 5-Finaly put the frond in an oven for 2 hours on a 60 degree heat. • 6- Cut the frond strips 1-2cm pieces. • 7-Use the hot press machine to merge the chemically treated natural fibers with polystyrene waste.
  • 16. Part B: Testing Mechanical Properties. We made 3 samples: • The first: only with polystyrene waste. • The second: polystyrene waste with treated fibers placed randomly. • The third: polystyrene waste with treated fibers placed with orientation.
  • 17. Dynamic Mechanical Analyzer • Better mechanical response with the samples including fibers • Fibers orientation exhibits highest values of the elastic modulus and less deformation. 1E-3 0.01 0.1 10 9 2x10 9 3x10 9 4x10 9 5x10 9 Pure PS PS with fibres PS with oriented fibres Elastic,G´,andloss,G´´,moduli(Pa) strain (%) 0.1 1 10 2x10 9 3x10 9 Pure PS PS with fibres PS with oriented fibres Elastic,G´,andloss,G´´,moduli(Pa) frequency, f (Hz) •Samples are slightly dependent on the frequency, means that all samples were appropriate developed structure with no defect. •Fibers orientation exhibits highest values of the elastic modulus. Conclusion: Oriented fibers considerably reinforced the mechanical properties of the PS matrix.
  • 18. The Green Plastic Results: • The purpose of using The Green Plastic is to decline the usage of the harmful plastic, so no harm is left due to the usage of plastic. • The usages of it are quite endless. The Green Plastic could be used in many industrial fields.
  • 19. The Green Plastic Recommendations: • This product could be used in different fields. • We would really like to see further investigations into the uses and properties of this plastic. • To enhance mechanical properties, use additional chemical treatment such as the peroxide treatment.
  • 20. Conclusion The green plastic will surely benefit our environment by decomposing easily and not leaving any harms behind. Through Al-bairaq’s project we all gained : • The team spirit, we stood by each other throughout the whole time . • How to analyze the experiments and how to come out with an overall conclusion. • The fundamentals of a basic research.
