At ONSA Refinery, we recognize the importance and value of the environment and believe that it must be protected in the best possible way to ensure a livable future for all forms of life.

In gold production, using secondary sources such as scrap materials instead of raw ore is not only technologically more feasible but also more efficient in terms of energy and material use — and far cleaner from an environmental standpoint.

In the gold recovery process, a significant portion of production costs arises from the operations required to make waste materials environmentally safe. As part of our commitment to a sustainable environment, we focus on optimizing chemical usage, improving energy efficiency, managing waste in full compliance with legal requirements, minimizing waste generation, and ensuring the recycling of recoverable by-products.

To prevent environmental pollution, we monitor and comply with all applicable national and international environmental regulations, aiming for continuous improvement in our environmental performance.

With our Recovery License for Hazardous and Non-Hazardous Waste, granted by the Ministry of Environment, Urbanization and Climate Change of the Republic of Türkiye, ONSA is dedicated to minimizing environmental impact and contributing to the national economy.
