to conservation of natural resources in the steel industry, it has become one of the most important pillars of the notion of sustainability. By virtue of this, briquetting plant was installed in 2010 for the recycling of residues containing iron and carbons originating from the different production stages, studies are carried out on magnetic separation to increase recycling ratio of solid wastes. In addition, national competent authority approved that Basic Oxygen Furnace slag can be used for road construction as the result of Erdemir’s studies. Monitoring emissions and waste water parameters continuously in the scope of index enables the assessment of most significant effects and best available technologies for the removal of these effects. In this context, two main investments were realized in 2011. A new electrostatic precipitator was taken into operation in 2011 on the Sinter Plant Waste Gas System. The applied technology is the system designed for Sinter Plant so that the dust concentration was reduced by %90 - %95. To improve the discharge values from Coke Plant, Ammonia Stripping Unit providing the removal of significant parameters was installedin 2011. As the climate change is a challenge of our century, CO2 emissions are calculated by the developed method taking into account of content of all fuel and the raw materials used in Erdemir. CO2 reduction from the energy efficiency projects are also calculated and assessed the reduction CO2 emissions. Implementation of environmental activities on the basis of the process approach ensures the comparison and evaluation of environmental effects from Erdemir’s production with the laws, rules, regulations, performance standards and voluntary agreements. In addition the best available techniques and technologies to control of negative effects are assessed in this context. Thus, based on results of measurement and data analysis, minimize or control environmental impacts are carried out by a proactive approach. Future Plans: Because of ongoing changes in the environment and challenges to the generation, continuous improvement is an important topic. Most importantly, the environmental performance needs to be continuously improved. Process Management Group does a periodic review in order to identify methods to continuously improve Environmental Performance Index and its indicators. Modeling systems are planned to be used with the index indicators. Discharges and emission parameters assessed in the scope of index will be used in modeling systems to monitor air and water quality around the company. Lessons learned: EPI helps the company assess and understand its impacts on the environment. This is one of the most important objectives of EPI so that defined indicators have to be reflecting and measuring the company’s environmental effects. As the environmental effects of whole factory are identified during the ISO 14001 Environmental Management Systems, selection indicators was not difficult but for calculation of index, the most part important part is to define the weight ratios (percentage of all parameters) of all parameters. Ratios have to be correct and right otherwise environmental performance index results will not be the real performance and it isuseless.. weight ratios are discussed by the Environmental Management Group until everyone was sure about the accurate weight ratios.
