Outline:• Introduction.• Activity 1: comparing packing materials. • Activity 2: hunting for biodegradable

objects. • Activity 3: Processing biodegradable

materials and comparing their mechanical properties.

• Activity 4: measuring the Degradation rate of biodegradable materials.

• Design Project: Designing a new biodegradable product.

• Product Idea: Fish feeding bio-capsules.

What is biodegradable?

A Biodegradable: product has the ability to break down safely. By biological means, into the raw materials of nature and disappear into the environment. These products can be solids biodegrading into soil, or liquids biodegrading into water

Introduction:

Objective: Comparing the effectiveness of two type of packing materials.

Procedure: First step: Filling two beakers with the same amount of water and add same amount of 2 materials one of them is biodegradable and the other one is non-biodegradable material.

A1: Comparing packing materials

Second step: Proving that both non biodegradable and biodegradable materials have the same physical effect as both protecting the fragile items.

Conclusion: The biodegradable foams degrade in water and the non-biodegradable foams didn’t degrade in the water.

Green foam didn't degrade in water White foam degrade in water

A1: Comparing packing materials

We have been searching about biodegradable materials and

non-biodegradable materials.

It shows that the biodegradable materials degrade easily in natural and the non-biodegradable materials don’t degrade in natural, and it causes many effects to the environment .

A2: Hunting for biodegradable and non-biodegradable materials:

in this activity we found out that there are many materials biodegradable like:

Wood Some types of Paper Food

And non biodegradable materials:

Glass bottles aluminum cans plastic containers

The development of biodegradable materials has also become important in the field of medicine , for example, orthopedic pins and screw.

A2: Hunting for biodegradable and non_biodegradable materials:

Example: Non biodegradable materials :

Example : Biodegradable : Materials

Like: Tin cans ,Plastic bags

The materials that wouldn’t degrade even after a long

time.

Like : Banana and some types of paper .

Are objects that degrade by nature.

A2: Hunting for biodegradable materials

Objective: Making gelatin films.

Procedure: By putting different amount of gelatin and HCL we made 2 type of gelatin films (5% and 10 %) and a Gel with 20% concentration.

A3: Processing biodegradable materials

Objective: Testing two different concentration of gelatin films, starch peanut and gelatin capsules in three different solutions.

Procedure: We use NaOH and HCL and hot water to degrade 3 films and gelatin capsules and some foam to measure the degradation of them.

A4: Measuring the degradation rate of biodegradable materials

Conclusion:

Measuring the degradable rate of biodegradable materials

Time taken to degrade

Time taken to degrade

Time taken to degrade

HCL NaOH Hot water

59 min 36 min 16 min Foam

31 min 63 min 11 min 20% gelatin film

47 min 88 min 4 min Gelatin capsule

Project design: designing a medicine-delivery device

The alginate beads represent the capsules. The food coloring represent the medicine in the capsules. We add them to sodium citrate solution which represent the human body.

The medicine (food dye) releases by diffusion, and after that the beads degrade.

Final Project/ product:-Make fish food inside capsules that degrade in water after few days. -Those capsules will contain fish food and when it degrades the fish will take the food and it will be in the period of the absence of the owner of the aquarium.

Final Project:Title: (Fish feeding Bio-Capsules)

Why we chose this product?We chose this project because the project must be

biodegradable and our project will help a lot of people who have fish.

The project is important to us and to Qatar because it will help the people who travel a lot and have fish tanks to feed there fish without sending someone every few days to feed them.

Final Project:Fish Feeding bio-Capsules

We expect that our project will help everyone who owns a fish aquarium or marine scientists in long term fish feeding from biodegradable materials that are eco-friendly and could be available at

commercial scale.

Fish Feeding Bio-CapsulesHypothesis:

The materials we will use in our project are: 1- water 2- corn starch 3- vinegar 4- glycerin 5- Fish food 6- Food Dye

Fish feeding bio-capsules

we put our product under experienceand that what happened:

Zero hour: after 5 hours:

Fish Feeding Bio-CapsulesResults:

After 12 hours: after one day:

And the food start to get out

Fish Feeding Bio-CapsulesResults:

After 2 days: after 3 days:

Fish Feeding Bio-CapsulesResults:

1-Help people how travel a lot to feed their fish secure manner,

And without any obstacles.2- Protect the fish from death during the period of

travelling.

Fish Feeding Bio-CapsulesResults:

Further investigations could be done to improve the product to be released in the market.

The idea can be improved by the experts and presented for companies to solve that problem completely.

Fish Feeding Bio-CapsulesRecommendations:

Participating in Al-Bairaq project was really useful. We learned a lot of things about biodegradable materials and how some materials degrade. We also did some experiments that were definitely interesting.

Conclusions (Overall of the whole module)

Many thanks to my teachers, school and 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, Ras Gas, Maersk and Shell.
