3. Introduction
Definition of biodegradation
In the dictionary it is a verb (used without an object)and
means to decay and become absorbed by the environment.
Biodegradation mean to be broken down by natural factors
like micro living organisms such as bacteria and turned into
products that can be reused by the environment again.
Which are CO2 and water.

4. Activities
Activity 1: Comparing Packing Materials
Activity 2: Processing biodegradable materials
and comparing their mechanical properties
Activity 3: Measuring the Degradation
Rate of Biodegradable Martials
Activity 4:Making a Medicine Delivery
Device

5. Green Phone Cases
Introduction
In the last three years Apple company had produced and
sold 444 million iPhone cases. The average period of using
a single phone case is one year. These cases are made
from synthetic materials mostly plastic which will be
disposed and dumped eventually in landfills. These kinds of
materials will not degrade and will remain in landfills
forever.
Aim of the work
The aim of this project is to make biodegradable phone
cases that will degrade when disposed in landfills.
This idea is based on the concept of biodegradation and
the availability of degrading factors like bacteria in landfills.

6. Green Phone Cases
Hypothesis
A BIODEGRADABLE PHONE CASE MADE
FROM STRONG YET IMPACT ABSORBING
MATERIALS IS SUGGESTED TO SOLVE THE
ISSUE OF MILLIONS OF PLASTIC PHONE
CASES DISPOSES YEARLY.
THE CASE IS MADE FROM
MATERIALS LIKE CELLULOSE
PAPER AND GELATIN

7. Green Phone Cases
Methods and Materials
The unique cases are made from
Gelatin: to provide
flexibility
Cellulose: to
provide strength
Starch foam: to
absorb the impact
of any drop
Food coloring

8. Green Phone Cases
Results
The (Green Phone Cases) are strong and
biodegradable cases that can replace regular
cases
It positive impact on the environment is
expected to be great
Many designs can be made to fit all phones
brands
We can experiment with more materials can
make comparisons and studies

9. Conclusion
Biodegradable materials have great
benefits and uses .
We hope our product solves a big issue
and saves the environment.
