STUDY ON SORPTION OF MOISTURE BY THE ANADARA GRANOSA WASTE

High humidity in room temperature will cause mold formation and contribute to unpleasant odour especially in small places like wardrobe and shoe racks. Moisture
absorber is required in order to reduce humidity but the current moisture absorber in the market is costly and utilizes calcium chloride derived from limestone. Limestone mining gave several environmental problems such air pollution and erosion, (Langer, 2011). This project is to discover a greener alternative to producing calcium chloride which using Anadara granosa waste. Anadara granosa waste is the cockle shells which abundantly
available in Malaysia. This cockle shells has not yet discover the ability to produce moisture absorber medium, calcium chloride. The calcium and carbon content of cockle shell is equivalent to limestone makes it as an alternative to replace limestone as the raw material to produce calcium chloride. This experiment is to synthesis calcium chloride using cockle shell. Calcium chloride is the valuable chemical as moisture absorbent in any dehumidifier product. The experiment product was compared with the commercialize moisture absorber in sorption of moisture capability and the result shows that they are
comparable and have the tremendous opportunity to replace limestone as the raw material to produce calcium chloride. As the conclusion, this innovation will able help people to reduce the humidity in a particular disclose area and indirectly can utilize the cockle shell waste.
