Abstract

Due to the accumulation of non-biodegradable waste, such as disposable items, the demand to design ecologically friendly products has increased recently. Starch is one of the potential candidates since it is readily available, cheap, renewable, and biodegradable. However, the natural properties of sago starch have shown weak mechanical properties. Therefore, the modification of sago starch with glycerol was used to create thermoplastic sago starch (TPSS). Furthermore, the characterizations of the TPSS were investigated, and the best result was obtained from a previous study (Zuraida et al., 2012), which was 75% sago starch and 25% glycerol. Meanwhile, pineapple leaf fibre (PALF) is a flexible plant that may be viewed as a renewable resource for composite production. TPSS was used to create PALF reinforcements with weight ratios of 90:10, 80:20, 70:30, 60:40, and 50:50 TPSS mixes with varying weight percentages of PALF were created using a hot compression moulding at 190˚C for 50 minutes. Several testing, including physical and environmental testing, have been conducted to assess the qualities of bio-composites. The physical test results for moisture content and density shows decreasing pattern when the fibre PALF increase. However, the water absorption shows otherwise when adding fibre content cause the relationship with water increase. While PALF wt% loadings increase, soil burial decreases, despite water solubility statistics suggesting the contrary.
