Biodegradable, Develop Plastic from Yard Waste

  1. 1. AL-BAIRAQ I AM DISCOVERING MATERIALS BIODEGRADABLE MATERIALS GROUP NAME ABDALLAH MOSTAFA MOHAMMED SALEM JASSIM AL-JABER HASSAN ALI
  2. 2. OUTLINE• Introduction • Activity 1: Comparing packing materials (part A&B) • Activity 2: Hunting for biodegradable objects • Activity 3: Processing biodegradable materials and comparing their mechanical properties – Part A: Processing gelatin into a gel and films – Part B: Testing mechanical properties • Activity 4: Measuring the degradation rates of biodegradable materials • Design Project: Designing a medicine release capsule
  3. 3. INTRODUCTION • Biodegradation: is the process by which organic substances are decomposed by micro-organisms (mainly aerobic bacteria) into simpler substances such as carbon dioxide, water and ammonia
  4. 4. ACTIVITY 1: COMPARING PACKING MATERIALS (PART A) • Procedure: 1- Bring equal amounts of water in 2 Beaker. 2- add a different kinds of cork ( one is a Biodegradable and one is not )
  5. 5. ACTIVITY 1: COMPARING PACKING MATERIALS (PART B) • Results: After the experiment we see the Biodegradable cork is dissolved in water and the non- biodegradable not effected in the water .
  6. 6. ACTIVITY 2: HUNTING FOR BIODEGRADABLE OBJECTS Biodegradable Materials Non-biodegradable Materials is the process by which organic substances are decomposed by micro-organisms into simpler substances . substance is cannot be changed to a harmless natural state by the action of bacteria. Example: 1-Food waste 2-papers Examples: 1-plastic 2-aluminum cans
  7. 7. ACTIVITY 3: PROCESSING BIODEGRADABLE MATERIALS AND COMPARING THEIR MECHANICAL PROPERTIES PART A: PROCESSING GELATIN INTO A GEL AND FILMS. • Preparation: • 1 capsule is 0.1 g • Prepare 5% w/v film : 5 capsules + 10 ml HCl • Prepare 10% w/v film : 10 capsules + 10 ml HCl • Prepare 20% w/v film : 20 capsules + 10 ml HCl • Procedure: • Dissolve the capsules in the HCL on 60 Celsius degree • Let dry for 2 days
  8. 8. ACTIVITY 3: PROCESSING BIODEGRADABLE MATERIALS AND COMPARING THEIR MECHANICAL PROPERTIES PART B: TESTING MECHANICAL PROPERTIES • Compare between the films and gel • Observations: 5% and 10 % films (Less concentration) 20 % gel (More concentration) Less Viscoucity More viscoucity More Transparents Less transparents Less thickness More thickness White Nearly to orange
  9. 9. ACTIVITY 4: MEASURING THE DEGRADATION RATES OF BIODEGRADABLE MATERIALS • Objective: Test the effect of pH, temperature and concentration on the degradation rates of the gel, films, packing material (starch), and gelatin capsule. • Steps:
  10. 10. ACTIVITY 4: MEASURING THE DEGRADATION RATES OF BIODEGRADABLE MATERIALS • Results: Boiling water PH=7 HCl PH=4 NaOH PH=10 5% 2 sec 1:30 min 3 min 20% 5 sec 6-8 min 10-11 min Gelatin Capsule 3 min 32-34 min 44-46 min Packing material (Starch) 11 min 3 hours 3 hours • Conclusion: 1- when the concentration increase the rate of degradation decrease. 2- The HCL is faster to degredat than NaOH. 3- The temperature is one of the fastest way to degredate if the temperature increase the rate of breaking down the molecules increase so the degredate increase.
  11. 11. DESIGN PROJECT: DESIGNING A MEDICINE RELEASE CAPSULES • Objective: Simulation of drug release and capsule degradation inside the human body • Procedure: • Drop Sodium alginate into Calcium Chloride and wait for 10 minutes and then filter the beads (capsules are ready) • Soak the beads into colors (as medicine) and wait for 30 minutes and then filter the beads again • Now the medicine capsules are ready • Drop the capsules inside Sodium citrate (human body) and notice what happens
  12. 12. DESIGN PROJECT: DESIGNING A MEDICINE RELEASE CAPSULES • Observations: • We notices medicine release in the solution • After a while, the capsules start to degrade • Conclusion: • Biodegradable materials are used heavily in medical and industrial applications
  13. 13. FINAL PROJECT: DEVELOP PLASTIC FROM YARD WASTE • Introduction: In an effort to make plastics more environmentally friendly, we has found a way to make plastics from yard waste. Traditional plastics are made from oil and recently some companies have been making plastic out of food products , like cane sugar and corn starch. But what if we make the plastic from waste of yard . Of course it will be very useful to the environment .
  14. 14. TITLE OF YOUR PROJECT IDEA AIM OF THE WORK (OBJECTIVES) (‫البحث‬ ‫)هدف‬ 1- to protect environment . 2- Minimize use of Petroleum products to Plastic Processing. 3- bioplastic Do not need catalysts to decompose 4- Minimize use of food material like : - cane sugar : - corn starch :
  15. 15. TITLE OF YOUR PROJECT IDEA MATERIALS. 1-Yard Waste: includes leaves, grass clippings, tree trimmings, and other plant materials. 2- lactic acid: is an organic compound. In its solid state, it is white and water-solubleI its liquid state, it is colorless. 3-Calcium carbonate : is a chemical compound . It is a common substance found in rocks as the minerals calcite and aragonite
  16. 16. DEVELOP PLASTIC FROM YARD WASTE RESULTS: (‫)النتائج‬ • 1-Get bio-plastic can dissolves in the soil 2-minimize use of Petroleum products to Plastic Processing. 3- keep our environment safe • 4- industry bio-plastic by waste of the backyard.
  17. 17. DEVELOP PLASTIC FROM YARD WASTE RECOMMENDATIONS: (‫)التوصيات‬ • First we should use it in home . After we can use it in a lot of places like * gardens – play grounds The cost of this product will be very few compared to the conventional methods of the plastic industry.
  18. 18. CONCLUSIONS (OVERALL OF THE WHOLE MODULE) • We can use many materials to protect our environment . This product will help in many different fields of works
  19. 19. ACKNOWLEDGMENT 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.
