Alunorte, the world’s largest alumina refinery, is accelerating the use of drone technology after investing about USD 633,000 in a fleet of 15 drones for equipment inspection, environmental monitoring and security management. The company said drones can replace some confined-space and high-altitude operations while reducing visual inspection time by around 80% and improving inspection accuracy. In the first three months of 2026, the program generated an estimated USD 1.19 million in financial returns through reduced downtime and lower scaffolding needs. Alunorte noted that drones combined with artificial intelligence and thermal imaging will further enhance operational efficiency, safety and sustainability management.
