Abstract/Executive Summary
The study explored the sustainable use of hydroxyapatite (HAp) from Nile tilapia (Oreochromis niloticus) scale waste as an additive in porcelain tile production, focusing on enhancing the mechanical properties while addressing environmental concerns. This study addresses environmental concerns related to improper waste disposal and seeks alternative sources of raw material additives for ceramics. The methods involved extracting HAp from Nile tilapia scales and mixing them into the porcelain tile mixture, including a negative control setup of 0% HAp, and experimental setups of 5% and 10% HAp. Tiles with 5% and 10% HAp demonstrated increased flexural strength (11.441 MPa and 11.446 MPa, respectively) compared to the negative control (9.716 MPa), indicating enhanced resistance to bending. Although compressive strength also increased, inconsistencies in sample uniformity impacted the tile performance. Thus, the findings highlighted the potential of HAp from biogenic sources in enhancing tile performance while repurposing waste for construction materials, offering insights for advancement in material science, and promoting environmentally sustainable solutions to improper waste disposal.
