R&D and Advanced Technology We engage in extensive R&D studies with the aim of maximizing quality and production efficiency. Focusing on sustainability and advanced technology in the exploration of natural resources and the improvement of existing processes, our R&D Center has become a scientific hub for the mining sector through collaborative research with Türkiye's leading institutions and universities.

Our Sustainability Approach The Sustainable Development Goals adopted by the United Nations (UN) to ensure the common welfare of humanity by 2030 guide our objectives. We prioritize sustainability and high efficiency in all our operations, placing great importance on the recovery of 'byproducts' emerging during mining processes. We work for a sustainable future.

Supporting the Agricultural Sector: Eti Gübre Eti Bakır takes on a pioneering role not only in mining but also in the agricultural sector. We support our farmers with Eti Gübre, the only fertilizer brand in Türkiye that uses 100% domestic raw materials. Our Quality Control Laboratory located in Mazıdağı is accredited by the Turkish Accreditation Agency (TÜRKAK). In addition, this plant is the first ammonium sulfate producer in Türkiye to receive CE certification.
