The facility generates steam needed by the factory by burning locally-produced fuel in its own Cogeneration unit, which also powers a steam turbine that meets the facility’s electricity needs, ensuring the exemplary and efficient utilization of energy resources by prioritizing environmentalism.
Energy Production Activity is one of the crucial steps in paper production, which is the part where boilers and steam turbines that produce the steam required for drying simultaneously generate the electricity required for operating the entire system.
A paper production facility that boasts a manufacturing capacity of 200,000 tons /year and 140 megwatts to meet the energy needs of the facility in question (40 MWe of electricity generation (when steam is not part of the process) /25 MWe (when steam is added to the process) was planned in 2016 within the scope of the “Paper Production Plant and Power Plant Project.”
The Environmental Impact Assessment (EIA) process was carried out within the framework of the aforementioned project in compliance with the the Environmental Impact Assessment Law published in the Official Gazette, dated 25 November 2014 and numbered 29186.
An “EIA Positive Decision” was made by the Ministry of Environment and Urbanization, General Directorate of Environmental Impact Assessment Permit and Inspection based on the letter dated 02/09/2016 and numbered E.14263.
In addition to the paper production facility built within this scope, the installed power generation plant that boasts a capacity of 140 MWt (electricity production 40 MWe (when steam cannot be supplied to the process)/ 25 MWe (when steam is added to the process) is fully operational.
Electricity and steam needed for the paper production facilities are met thanks to the power plant. In an effort to increase reliance on domestic resources at the power plant, a blend of imported coal (50%) and local coal (50%) is used in the facility in question.
The fly ash that is emitted in the cogeneration plant is intercepted with a Bag Filter and safely taken out of the system.
While SO2 gas emitted as a result of combustion is fed to the atmosphere below the limit values specified in the Industrial Sourced Air Pollution Control Regulation by adding lime to the boiler’s combustion chamber and through the (Flue-gas desulfurization) FGD system;

Wastewater resulting from the production process are discharged after being refined in a 7,000 m3/per day-capacity physical, chemical and biological purification units that keep contamination levels below standards. Part of the liquid waste is also reused in the facility’s own project to minimize water consumption.
The wastewater treated at the treatment facility is discharged to the receiving environment in accordance with Table 13.62 in the Water Pollution Control Regulation published in the Official Gazette dated 31 December 2004 and numbered 25687.
