Done by group: Alieman_Nebula
School Name: Al Ieman school for girls
Biodegradable Materials module: Students make, test and evaluate biodegradable films and gels. They use their knowledge gained during the workshop to design devices that release a dye in a controlled manner as they degrade. Finally they design their own biodegradable product.

There is no doubt that the plastic is one of the most non-biodegradable materials that grabbed the world’s attention. Replacing non-biodegradable plastics with biodegradable ones will have a great impact on the environment. The idea of this group is to use biodegradable materials in manufacturing children toys and party supplies, as the survey – which was given to the mothers – showed that the most annoying garbage in their houses are the children’s toys, plates, and cups waste.
Through their product, they aim to limit the amount of plastic that is being used in children toys and party supplies.

Biodegradable Materials, Biodegradable Party Supplies and Toys, IDM7

  1. 1. AL-BAIRAQ _7TH CYCLE I AM DISCOVERING MATERIALS BIODEGRADABLE MATERIALS Shooq Alsulaiti Dana Bu-hazaa Kholoud Ahmadi Fatma Al-abdulmalek Al-Ieman nebula7
  2. 2. OUTLINE • Introduction about biodegradable materials • Activity 1: Comparing Packing Materials • Activity 2: Hunting for Biodegradable Materials • Activity 3: Processing Biodegradable Materials and Comparing their Mechanical Properties • Activity 4: Measuring the Degradation Rate • Design Project: Designing a Medicine-Delivery Device • Product idea: Biodegradable Party Supplies & Toys
  3. 3. INTRODUCTION  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 the soil, or liquids biodegrading into water.
  4. 4. ACTIVITY 1: COMPARING PACKING MATERIALS Part A: Comparing the properties of biodegradable and non biodegradable packing material 1st step: Filling the two beakers with the same amount of water The starch peanut in the first beaker degraded, but the other polystyrene peanut didn’t degrade which means that the first peanut is biodegradable and the other one is not. 2nd Step: Placing two different type of peanuts in different beakers Biodegradable Non-biodegradable
  5. 5. Part B: Proving that both biodegradable materials and non-biodegradable materials have the same physical effect on protecting the fragile items. ACTIVITY 1: COMPARING PACKING MATERIALS
  6. 6. ACTIVITY 1: COMPARING PACKING MATERIALS WHY don’t we replace the non-biodegradable packing materials with the biodegradable ones?
  7. 7. ACTIVITY 2: HUNTING FOR BIODEGRADABLE OBJECTS We have been searching about biodegradable materials and non- biodegradable materials. It shows that the biodegradable materials degrade easily in nature and the non-biodegradable materials don’t degrade in nature, and it causes many effects on the environment.
  8. 8. BIODEGRADABLE MATERIALS: Fruits Hair Papers Plastic bags Hardware Bottles NON-BIODEGRADABLE MATERIALS: ACTIVITY 2: HUNTING FOR BIODEGRADABLE OBJECTS
  9. 9. ACTIVITY3: PROCESSING BIODEGRADABLE MATERIALS AND COMPARING THEIR MECHANICAL PROPERTIES Part A: Making gelatin film out of gelatin capsules The more number of capsules we add, the longer time it will take to dissolve and the thicker the films form Different concentration of gelatin films were prepared by dissolving gelatin capsules in HCl solution.
  10. 10. NaOH, HCl and boiling water solutions were added in three different beakers. ACTIVITY 4: MEASURING THE DEGRADATION RATE Cutting materials & unifying the weight
  11. 11. Testing 2 different concentration of gelatin films, starch peanut and gelatin capsules in 3 different solutions . As a result, many factors effect on the degradation rate 0 10 20 30 40 50 60 starch peanut 5% gelatin film 20% gelatin film capsules boiling water HCL NaOH ACTIVITY 4: MEASURING THE DEGRADATION RATE time Rate of degradation of each material
  12. 12. We add calcium chloride with sodium alginate to get alginate beads. Filter the beads and separate them into 3 petri dishes PROJECT DESIGN: DESIGNING
  13. 13.  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. PROJECT DESIGN: DESIGNING A MEDICINE- DELIVERY DEVICE
  14. 14. PRODUCT IDEA: PARTY SUPPLIES AND TOYS  There is no doubt that plastic is one of the most non- biodegradable materials that grabbed the world’s attention. Replacing non-biodegradable plastic with biodegradable ones will have a great effect on the environment.  What turned us to toys and party supplies is the results of the survey that we conducted on several mothers. The question that most mothers had the same answer to was what were the things that most mothers considered as non-degradable waste and often found in their houses? The answers gathered were children’s toys, plates, and cups waste …etc .
  15. 15. PRODUCT IDEA: PARTY SUPPLIES AND TOYS
  16. 16.  Large numbers of plastics are being consumed daily in parties.  We can replace them with biodegradable party supplies. Aim of the work We aim to limit the amount of plastic that is being used in parties and toys. PRODUCT IDEA: PARTY SUPPLIES AND TOYS
  17. 17. PRACTICAL APPLICATION
  18. 18. FIRST EXPIRMENT: THE CORN STARCH Hard & firm BUT Non-moldable
  19. 19. SECOND EXPERIMENT: RECYCLE OF PAPER Moldable BUT Too soft
  20. 20. PRODUCT IDEA: PARTY SUPPLIES AND TOYS HYPOTHESIS After making two experiments to make biodegradable plastics. 1) The corn starch experiment. 2) The paper experiment. We assumed that mixing the two experiments –paper experiment and the starch experiment- consequent a flexible and firm result.
  21. 21. PRODUCT IDEA: PARTY SUPPLIES AND TOYS RESULTS The mixture looking for new mechanical properties
  22. 22. THE BEST RESULT firm & hard AND Moldable
  23. 23. PRODUCT IDEA: PARTY SUPPLIES AND TOYS FUTURE OF OUR PRODUCT * Our idea applications is a lot due to the different type of toys and plates used in a large amount daily. * Success of this idea will reduce the amount of plastic deeply. * It solved the problem definitely and if it’s approved it will be a huge advantage in the future.
  24. 24. RECOMMENDATION  After we have solved the problems, we applied the idea in a simple way. Our ambition is to see our idea developed and applied in the future, in order to raise awareness about biodegradable materials and reduce the use of non-biodegradable materials.
  25. 25. CONCLUSION It is an experience that we have learned the following from: A lot of information The importance of biodegradable materials Teamwork and confidence
  26. 26. ACKNOWLEDGMENT Thank you everyone, teachers, friends, and our school for the big support during this journey in Al-bairaq project. Also big thanks to Al-Bairaq team and the sponsors who gave us the opportunity to be part of Al-Bairaq competition. Thank you!
