| الملخص: | In Malaysia, food waste had become a significant problem. These recyclable natural waste resources are channeled towards the production of value-added products e.g. hydroxyapatite; which can be used as photocatalyst and many other applications. This study synthesized hydroxyapatite (HAP; Ca10(PO4)6(OH)2) powder from food waste using the wet precipitation method. FTIR analysis was done on the synthesized hydroxyapatite powder, calcined samples, and raw materials for each resource to study the functional group and the changes of composition in each sample. The Life Cycle Analysis (LCA) study done in this paper comprises goal and scope definition, life cycle inventory, life cycle impact assessment as well as interpretation of data. Based on the results obtained, FTIR analysis shows that the synthesized powder is indeed hydroxyapatite based on the presence of important features such as CO3 2- and PO4 3- and OH group and eggshell is proven to be the ecofriendliest resource as the production process contributed only 1% to environmental impact. © 2022 Trans Tech Publications Ltd, Switzerland.
