Abstract

Plastics are materials that are particularly flexible and have found use in a wide variety of applications, from easy packing to detailed engineering. The production of plastics has overtaken that of steel globally and still expanding. The manufacture of plastic products usually uses petroleum-based polymers and some of petroleum-based plastics are non-biodegradable. Consequently, the environment will be affected because the waste of non-biodegradable does not decompose. Sago starch has been broadly uses from food industry to manufacturing industry. However, there are some disadvantages of sago starch. Hence, this research presents the study of physical and environmental characterization of sago starch mixture with glycerol. The mixtures of sago starch with different weight percentages (wt.%) of glycerol as thermoplastics sago starch (TPSS) bio-composite. The mixtures of sago starch/glycerol contents were at 60/40 wt.%, 65/35 wt.%, 70/30 wt.%, 75/25 wt.%. The mixtures of sago starch / glycerol were made by using hot compression moulding machine to produces TPSS samples. The physical and environmental characteristic were done: Density testing, moisture content testing, water absoprtion testing, water solubility testing and soil burial testing. The physical test graph result show increment pattern on density testing. However, the graph result for moisture content testing, water absoprtion testing and water solubility testing shown decrement pattern. Last but not least, the environment test on soil burial graph result also shown decrement pattern.
