Marzinc was established by Çolakoğlu, Diler, İçdaş, Kaptan and Kroman steel companies in order to recover economically valuable metals in EAF dust. The Waelz Process operated by Marzinc is implemented in Europe and eco-friendly countries such as US. This process requires a big know-how, and technology. Assuming responsibility, Turkey’s leading five steel producer companies gathered their financial potential and know-how required to run the project under a single roof, and presented Marzinc idea to Turkey.

The Ministry of Environment and Urbanization supported the idea of treating EAF dusts by Turkish steel producers at the very beginning in order to recycle the waste resulting from the iron and steel production in a healthy and economical way. The Ministry gives its full support to such investments through the Iron & Steel Producers’ Association.
The producers in the Marmara Region, where almost half of the iron-steel production of Turkey is carried out, pioneered Marzinc’s establishment upon request and with the support of the Ministry and presented this important facility to the industry. This facility which was established with the support of the ministry also has “Positive Environmental Impact Assessment” issued by the Ministry.
