This study investigated the physicochemical, structural, and thermal characteristics of avocado seed powder for its potential as a bio-based material for composite and other applications. It was observed that the seed powder exhibited a mildly acidic pH of 5.3, with limited levels of solubility in different solvents emphasizing its viability in vastly insoluble biopolymers. FTIR analysis confirmed the presence of carbonyl, hydroxyl, aromatic, and aliphatic functional groups characteristic of lignocellulosic biomass. TGA/DTA results showed major mass loss occurring between 380–550 °C and approximately 20% residual mass at 950 °C which is an indication of thermal stability and char-forming potential. SEM imaging showed irregular, fibrous, and porous particles with rough surfaces and micro-fractures, which creates viable interfacial adhesion in composite matrices. EDX results demonstrated a carbon-rich surface with trace mineral elements, including notable iron content. Taken together, these results highlight the potential of avocado seed waste as a viable additive in biodegradable composites, heat-resistant materials, and sustainable bio-products. Beyond these immediate applications, the findings suggest potential outcomes such as the development of antimicrobial packaging films, eco-friendly adsorbents for wastewater treatment, and thermally stable bio-char for energy storage or soil amendment.
