Eco-Moisture Sorption

  1. 1. ECO-MOISTURE SORPTION (EMS) ETP GROUP 56 NIK ALIFF SYAZREEN BIN SABRI 13526 MOHAMAD SAFWAN SYAHIR BIN MOHD AZMI 13548 MOHAMMAD SHAFIQ BIN MOHAMMAD ASHRAF 15208 MOHAMED ABDELGADIR MOHAMED AHMED ELFAKI 15800 CLAIRE CHANG LI SI CHANG AIK LENG 13779 SITI FATIMAH ILI BINTI OMAR 13913 SUPERVISOR : AP DR SUZANA BINTI YUSUP
  2. 2. CONTENT Introduction Background Studies Methodology Project Planning Result and Discussion Conclusion and Recommendations
  3. 3. INTRODUCTION • Problem statement • Objectives
  4. 4. PROBLEM STATEMENT • Cockle shell dumped and left untreated • Quarrying of CaCO₃ lead to air & noise pollution
  5. 5. OBJECTIVES Main Objective - To convert waste to value-added product Additional Objective - To reduce waste material - To obtain alternative source of CaCO₃ - To apply the use of CaCO₃ in the daily life
  6. 6. BACKGROUND STUDIES • Literature review
  7. 7. LITERATURE REVIEW Three (3) main elements in Eco-Moisture Sorption : i) The source – cockle shells ii) The medium – small container ii) The other usage – potpourri Calcium carbonate extracted by quarrying – deforestation and environmental damage Alternative – cockle shells – 95-99% CaCO₃
  8. 8. LITERATURE REVIEW Application of CaCO₃ - dehumidifier Main absorbent is Calcium Chloride, CaCl₂ : - derived from cockle shells - exothermic reaction - great capacity to attract moisture - very fast drying agent No previous researches – dehumidifier by using CaCO₃ extracted from cockle shells
  9. 9. METHODOLOGY • Preparation of CaCl₂ • Preparation of fragrance
  10. 10. PREPARATION OF CACl₂ CaCO3 + 2HCl → CO2 + H2O + CaCl2
  11. 11. PREPARATION OF FRAGRANCE
  12. 12. PROJECT PLANNING • Project flow • Task distribution
  13. 13. PROJECT FLOW Week 1 and 2 : brainstormed ideas Week 3 : make use of waste product(cockle shells). Week 4 : required procedure – research. Week 5 and 6 : optimum condition - factors affecting yield.
  14. 14. PROJECT FLOW Week 7 : 1st run ; testing hypothesis. Week 8 : 2nd run ; apply optimization to increase yield. Product being contaminated. Need to re-run. Week 9 : 3rd run ; diluting the concentration of acid. Get the final product. Week 10 : Introducing fragrance from waste materials as well. Design the packaging.
  15. 15. TASK DISTRIBUTION MOHAMAD SAFWAN SYAHIR BIN MOHD AZMI  Leads the team, plan and conduct weekly meetings and activities.  Allocates tasks to all members.  Monitors progress of project.  Make sure all the project activities are done on time. CLAIRE CHANG LI SI  Heads meeting when leader is unavailable.  Keep record of all the data and document.  Ensure all the necessary documents are done properly. SITI FATIMAH ILI BT OMAR  Keep record of the group’s expenditure.  Manage budget and money flow for project.  In-charge of all the claims (fill up the Students’ Requisition Form). MOHAMMAD SHAFIQ BIN MOHAMMAD ASHRAF • Develops the mechanism for the prototype. • Design technical part of the project. • Ensure project materials are in shape. MOHAMED ABDELGADIR MOHAMED AHMED ELFAKI  Gather relevant information and decide on the best material.  Keep updated with the progress of project and find ways to improve it. NIK ALIFF SYAZREEN BIN SABRI • Lead the design process. • Design the prototype in Autodesk Inventor and in conceptual sketches before fabrication.

  23. 23. PROTOTYPE COMPARISON Our Product / gram Commercial / gram Before (t=0) 17.30 g 16.50 g After (t = 60 m) 17.44 g 16.64 After (t = 3 days) 19.61 g 18.82 g Weight of water absorbed (t = 60 m) 0.14 g 0.14 g Weight of water absorbed (t = 3 d) 2.31 g 2.32 g
  24. 24. RESULT
  25. 25. DISCUSSION • Calculation • Economical consideration
  26. 26. CONCENTRATION OF CaCO₃ Theory 15 g of CaCO₃ yields 16.5 g CaCl₂ Experiment 15 g of CaCO₃ yields 11 g of CaCl₂ Concentration of CaCO₃ in the cockle shell is calculated to be 66.7%
  27. 27. ECONOMICAL CONSIDERATIONS Item Cost per unit(450g) Cockle Shell FREE Hydrochloric Acid RM0.70 Filter paper RM1.10 Lime skin/Flowers FREE Scented Oils RM0.05 Container RM0.50 Miscellanous RM0.30 Total RM2.65
  28. 28. CONCLUSION & RECOMMENDATIONS
  29. 29. CONCLUSION Production of scented green dehumidifier from waste material. Waste Material ( Cockle Shells ) EMS Product
  30. 30. CONCLUSION EMS advantages: 1) Cost Competitive 2) Eco- Friendly 3) Contents of the EMS is biodegradable and the plastic container is recyclable. EMS Product
  31. 31. RECOMMENDATION  Mixing Cockle Shells from different places to have higher percentage of CaCO3 .  Optimizing lab experiment environment such as: 1) Concentration and amount of HCL used 2) Temperature and pressure  Provide small Sachet filled with pure CaCL2 in the market.  Use Petals for another flowers which can preserve its odour for much longer time such as Jasmine.
