4. Introduction
As we become more technologically advanced, we
produce materials that can withstand extreme
temperatures, are durable and easy to use. Plastic bags,
synthetics, plastic bottles, tin cans, and computer
hardware- these are some of the things that make life
easy for us.

5. Activity (1)
.Comparing Packing Materials
Part A
Procedure :
Drop two pieces of different materials in the water,
and wait for few minutes to see the result .
Objective:
Find out which backing materials is
biodegradable.
Result:
We put starch in the
beaker A and it disappeared after a minute so it’s
biodegradable. But, we put polystyrene in the beaker B and it
takes more time to disappeared so it’s non-biodegradable.

6. Activity (1)
.Comparing Packing Materials
Part B
Objective:
Test the function of different packing materials (starch and polystyrene ) .
Procedure :
Put in a bag the two different materials then
put an egg in each bag, throw it from different
heights and see the result.
Result:
A biodegradable packing material can be as
effective as a non biodegradable packing
material in protecting an egg from breaking.

7. Activity (2)
Hunting for Biodegradable Objects.
Biodegradable
“biodegradable” product has the
ability to break down, safely and
relatively quickly.
Plants Food ,fruit Paper

8. Activity (2)
Hunting for Biodegradable Objects.
Non-biodegradable means that the
components of the item will not break down
over time .
Plastic bags
Plastic Aluminum cans polystyrene

9. Activity (3)
Processing Biodegradable Materials and
Comparing Their Mechanical Properties .
Objective:
Making gelatin films.
Procedure :
Process gelatin, a biodegradable
material, into a gel and into two
films that vary in density.
Result:
The low concentration dissolves
faster.

10. Activity (4)
Measuring the Degradation Rates of Biodegradable
Materials.
Objective:
Test the effect of pH and temperature and
concentration on the degradation rates of the gel
films, packing material (starch), and gelatin
capsule.
Result: Environmental conditions (PH level,
concentration, temperature and surface area) can
affect the rate at which a biodegradable
material breaks down.

12. Designing project Designing a Medicine-Delivery
Device
Objective:
Making a simulation of
medicine-delivery device.

13. Designing project
Designing a Medicine-Delivery Device
Procedure :
Step 3:
Dye release
(represents drug release in human blood)
Put beads in sodium citerate
Step 1:
Make Alginate beads (represents capsule)
sodium alginate + calcium chloride
Step 2:
Soak in dye (represents drug)

14. Designing project Designing a Medicine-Delivery
Device
Result:
•Dye release.
•Biodegradation of beads.

15.  Introduction and Rationale(continue)
 • We developed a surprising way to make tossing out
future smartphones and tablets easier on the
environment and the conscience. They’re replacing the
bulk of toxic and non-biodegradable materials in modern
microprocessors with wood. • Our project introduces a
green technology that give commonplace gadgets an
environmentally-friendly makeover through
biodegradable materials and kinetic energy We
developed a motherboard from a wood product called
cellulose Nano fibril coated with epoxy, which prevents
it from expanding or attracting moisture like wood
usually does.:

16.  • Aim of the work (objectives) • Develop a motherboard that have
the potential to replace the bulk of toxic and non-biodegradable
materials in modern microprocessors. • Make a new technique
replaces the metal toxic motherboards with a transparent, flexible
material made from wood pulp.

17.  • Assume that the motherboard will function at the same quality
of the old metal motherboard • Assuming that Cellulose
Nanofibril could be manufactured at low cost inside Qatar •
Assume that copper connections are enough to provide the
required conductivity between motherboard components.

18. Cellulose Nanofibril (CNF) CNF is a flexible, transparent
material made by breaking down the cell walls of wood to
the nano scale and forming it into sheets, much like paper.
Eboxy: Epoxy is either any of the basic components or the cured
end products of epoxy resins, as well as a colloquial name
for the epoxide functional group
Copper connections: Copper is a chemical element with symbol
Cu (from Latin: cuprum) and atomic number 29. It is a soft,
malleable, and ductile metal with very high thermal and
electrical conductivity

19.  Replace the rigid base or substrate material in smartphone and tablet
motherboards, often comprised of the arsenic-containing compound
gallium arsenide, with cellulose nanofibril (CNF).

20.  • The motherboard can almost
entirely biodegrade in a landfill, and
provide an eco-friendly solution to e-
waste. • The amount of potential e-
waste generated by all these devices
combined with the amount of rare
materials—gallium arsenide and
others—that can be saved by using
wood-based materials in electronics
will eventually make both financial
and environmental sense.

21. • Getting massive boars-fabrication plants, and
the companies that employ or own them, to
shift to newer, more eco-friendly methods
when current techniques are so inexpensive.
When scaled up however, the costs for creating
CNF from renewable wood should be
inexpensive as well, helping entice device
makers to switch from more traditional
substrates.

22.  Conclusions
 Using this material ( cellulous) in making
motherboard will reduce pollution
