3. 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.

to energy

6. 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.

7. 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.

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

9. 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

10. 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.

11. 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.

medicine-delivery device.

14. 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)

15. Designing project Designing a Medicine-Delivery
Device
Result:

•Biodegradation of beads.

16.  Introduction and Rationale:
 A Balance between Development Needs and Protecting the
Environment, Qatar National Vision 2030
 The State of Qatar has one of the highest waste generation rates
worldwide. In 2012, Qatar generated 8,000 tons of solid waste daily
(this is excluding construction waste which amounts to 20,000 tons
additional waste per day). This number is predicted to reach 19,000
tons/day in 2032, with an annual growth rate of roughly 4.2%.1
Most of these wastes end up in landfills – in 2012, more than 90% of
Qatar’s solid waste were sent to landfills although the government is
doing its efforts to reduce this amount. This percentage is extremely
high compared to many industrialized countries in Europe and Asia
(e.g. Austria, Denmark, Netherlands and Japan) where less than 10%
of solid waste are disposed of in landfills. These countries have high
recycling rates, have invested in technologies that convert waste into
energy

17.  Aim of the work (objectives)
 Biomass: is the material derived from plants that use sunlight to
grow which include plant and animal material such as wood from
forests, material left over from agricultural and forestry processes,
and organic industrial, human and animal waste.
 Sources of Biomass:
 Biomass comes from a variety of sources including wood from
natural forests, agricultural residues, agro-industrial wastes,
animal manure, and organic industrial wastes

18.  Is this project applicable in Qatar?
 Will it have no harm on the environment during the manufacture
process?
 The required materials available and can be easily gathered?

19. Methane fermentation is the key technology for the methane
production. Organic substances contained in biomass are
dissolved and turned in to methane by germs that perform
anaerobic-digestion. Methane fermentation is the best for
food-waste because food-waste has much moisture and
various kind of organic component

20.  Reduce the state's dependence on oil and gas and to find alternative
sources of income.
 Establish more factories that contribute to the increase in production.
 Biomass reduces emissions and enhances carbon sequestration since
short-rotation crops or forests established on abandoned agricultural land
accumulate carbon in the soil
 Biomass can play a major role in reducing the reliance on fossil fuels by
making use of thermo-chemical conversion technologies
 the increased utilization of biomass-based fuels will be instrumental in
safeguarding the environment

21.  Our dream that we can see this project on the
land of our country Qatar to save the
environment and produce new source of
energy according to Qatar National Vision
2030.

22. Using methane from bio-waste as a source of
energy will decrease pollution and save money

23. Many thanks to AL-Bairaq team from Center for Advanced
Materials (CAM), Qatar University for supporting us
during our journey with a AL-Bairaq.
Also, I would like to thank the sponsors UNESCO, Qatar
National Commission, and Shell.
