Introduction Eggshell waste can be categorized as one of the food waste. Eggshell is produced by egg processing industries in large quantities. Furthermore, large quantities of the waste are still disposed as waste in landfills without any pre-treatment. Eggshell will turn to waste because they are useless after the production of eggs and eggs derivatives. It also comes from domestic sources such as restaurant, homes, poultries and hatcheries. High consumption of eggs has resulted in large quantities of eggshell being disposed [1]. Eggshell typically comprises of ceramic materials made up of three layered frameworks, known as the exterior surface cuticle, a spongy (calcareous) layer and an internal layer. The cuticles contain in negligible quantities of calcium, magnesium, phosphorus, carbon and oxygen. Silicon as major components as well as sodium and chloride[2]. In recent study, eggshell waste has turned out to be a value product after gone through several processes. These applications included various uses such as the development of advanced bone tissue repair material (hydroxyapatite) or their uses as adsorbent for many metal ions. In addition, there has been a recent drift towards the use of eggshell wastes as an environmental friendly catalyst in various processes [3]. In this research, using of eggshell waste as a low-cost water filter need to be identified and analysed. The mechanical and physical properties of eggshell wastes after going through the process of cold compaction can be identified by conducting Abstract: Utilization of eggshell waste is a significant solution to reduce environmental problems. The aim of this research is to study the potential of eggshell waste as water filter. Eggshell waste (ESW) is the primary material that has been used in this research. Both types of binder which are kaolin clay and wheat flour were added to the eggshell waste. Different composition of eggshell powder (ESP) (20%, 30%, 40%, 50%), kaolin clay (10%, 20%, 30%, 40%) and 40% fixed of wheat flour were prepared. The mechanical and physical properties of eggshell waste were analysed through compressive test, turbidity test, density test and porosity test. Both mechanical and physical tests are followed American Society for Testing and Material (ASTM). The loading rate for compressive test was 1.5mm/min following ASTM B939 with samples size of 25mm x 5mm. Meanwhile for porosity and density test were followed ASTM C642 and B962. Based on comparison results, the addition of eggshell powder has increased the compressive strength of the tested material. The result from turbidity test exhibits that the level of turbidity decrease when added eggshell into the waste water. The porous structure of the eggshell has influenced the absorption of contaminants from the waste water Keywords: Eggshell Waste, Water Filter, Cold Compaction
