The palm oil industry generates significant waste, such as POME, which can pollute the environment if not properly managed. POME can particularry damage aquatic ecosystems. Treating POME is crucial for the sustainability of this industry. Advanced Oxidation Processes (AOPs), including photocatalysis, are being developed as a technological option to degrade organic compounds in POME waste. In this study, the photocatalytic degradation of POME waste using WO3-based catalysts and a 500 W Xenon lamp showed that this method effectively breaks down POME waste. WO3 photocatalysts were synthesized using a hydrothermal method at temperatures of 180, 200, 220, and 240°C, resulting in hexagonal and orthorhombic crystal structures and Type V mesopores. Using WO3 at a concentration of 1 g/L can reduce Chemical Oxygen Demand (COD) up to 48.05% , color degradation by 36.22%, with a COD reaction rate constant of 3.7×10-3 min-1.
