PROBLEM STATEMENT

• Cockle shell dumped and left untreated

• Quarrying of CaCO₃ lead to air & noise pollution

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

BACKGROUND STUDIES• Literature review

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

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

METHODOLOGY• Preparation of CaCl₂• Preparation of fragrance

PREPARATION OF CACl₂

CaCO3 + 2HCl → CO2 + H2O + CaCl2

PREPARATION OF FRAGRANCE

PROJECT PLANNING• Project flow• Task distribution

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.

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.

CONCLUSION & RECOMMENDATIONS

CONCLUSION

Production of scented green dehumidifier from waste material.

Waste Material ( Cockle Shells )

EMS Product

CONCLUSION

EMS advantages: 1) Cost Competitive 2) Eco- Friendly 3) Contents of the EMS is biodegradable and the plastic container is recyclable.

EMS Product

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.
