Since its establishment, ONSA has operated with transparent management principles and a strong commitment to social values, continuously reinforcing this vision through dedicated and forward-looking investments.
This perspective enables ONSA to remain fully aligned with global environmental standards while maintaining a high level of social awareness — implementing initiatives that create positive and lasting impacts on both the environment and society.
The cornerstones of this approach include the use of advanced technologies to enhance energy efficiency, prioritizing recycled gold in production, and taking active measures to reduce carbon emissions.
Within our refining system, the control of heavy metals and hazardous chemicals, the safe disposal of hazardous waste in full compliance with legal regulations, and the reduction and recycling of waste with a “zero waste” goal are among ONSA’s top priorities. By combining state-of-the-art technological infrastructure with an experienced and specialized workforce, ONSA has been recognized with multiple certifications — becoming one of Türkiye’s most trusted and environmentally responsible refineries.
