Eti Bakır Mazıdağı Plant Successfully Completes Scheduled Maintenance Shutdown

Eti Bakır, a group company of Cengiz Holding, has completed a planned maintenance shutdown at its Metal Recovery and Integrated Fertilizer Plant in Mardin Mazıdağı during the June-July 2025 period.

Environmental responsibility and occupational safety principles were prioritized throughout the work.

Critical Revisions for Production Safety
Within the scope of the approximately one-month planned shutdown, comprehensive maintenance and renewal work was carried out in different units of the facility.

• Sulfuric Acid Plant: Structural modifications were made to roaster units, revisions were performed on electrostatic filters and renewals were completed on SO₂ heat exchangers.
• Phosphoric Acid Plant: FRP coatings and brick coatings were increased, and capacity gains were achieved by switching to an endless belt system.
• Metal Recovery Plant: Distributed Control System (DCS) was upgraded and a redundant system was activated.
• DCS and DAP Plants: Critical maintenance and renewals were completed on high-pressure compressors and drum systems.
• Power Plant: Modernization work was completed on turbine, generator and fan systems.

Through these comprehensive efforts, facility efficiency was improved, unplanned shutdown risks were minimized and production safety was strengthened.
