Protecting the Climate and the Environment
Akçansa manages the efforts related to the fight against climate change through short- and mid-term targets in line with the risks and opportunities identified in the strategic management processes. In this context, Akçansa’s insight on managing the climate change risks is structured by improving the operational processes, developing new products, acting according to low carbon strategy in entire product life cycle, and attending to the local and international initiatives.
Therefore, for all activities, Akçansa aims increasing the energy efficiency, reducing the polluting emissions, using alternative energy resources in cement production processes, and reducing the emission impacts of the products by using alternative raw material in the products. Akçansa develops performance increasing practices and cooperations by participating to the national, international, and sectoral initiatives for fighting against climate change, as well as develops opportunities for benefiting from the low carbon economy.
While setting the policies and practices related to the fight against climate change, Akçansa considers the Kyoto Protocol, International Climate Summit outcomes, and principles of the initiatives in line with these.
Akçansa continued with the Carbon Disclosure Project (CDP), which it has joined in 2011 in line with its transparency understanding, in Turkey also during the reporting period. In the assessment made within the scope of the application where the performance obtained on climate change strategy and measures taken is reported to the public and several international investor groups, Akçansa received 92 points in 2015 and listed among the most transparent companies of Turkey in terms of climate change impacts.
Akçansa has initiated the ISO 50001 Energy Management System certification efforts in 2012 for establishing energy management systems, and has received the first ISO 50001 certificate of the industry, covering 3 cement factories and Çanakkale port facility, in 2013.
Çanakkale Factory has realized an important energy resource saving move pioneering Turkey with the Waste Heat Energy Recovery Project launched in 2011. Waste hear recovery facility with a capacity of 15 MW established with the project allowed the reutilization of the waste heat emitted to the atmosphere in the furnaces.
With Waste Heat Recovery Facility, Akçansa is listed among the “Best Practice Examples on Sustainable Development” at the United Nations Conference on Sustainable Development, Rio+20.
Akçansa’s activities are consisted of emission intensive processes due to energy consumption and product features. Within the scope of Sustainability Targets 2020, emissions caused in all basic processes are carefully calculated and monitored, and efforts are being carried out for reducing them. Greenhouse gases such as carbon dioxide, as well as dust, nitrogen oxide, sulfur dioxide and other pollutant emissions in trace amounts are monitored and reduced. The process which the greenhouse gas emissions occur in the most apparent manner within the value chain is the energy consumption, as well as the cement production due to the calcination effect in the production process.
It’s been estimated that approximately 10% of the industry related CO2 emission in Turkey is arising from the cement production. Acting upon the awareness of this responsibility, Akçansa aims reducing the production caused emission amount through the use of alternative fuel and raw material. Alternative fuel consumption reduces the dependency to overseas in energy consumption, and also is an application with highest recognition level worldwide in reducing the emissions related to energy consumption. Clinker production is the process where the highest emission arises during the cement production. In addition to the energy consumption, CO2 arises due to the chemical reactions during the process. The most effective method in reducing this effect is reducing the rate of clinker within the cement composition by using qualified alternative raw material. In addition to energy efficiency, using alternative fuel and raw material constitutes the basis of Akçansa’s strategy for reducing the greenhouse gas emissions.
Alternative Fuel Usage
Cement industry traditionally uses fossil fuel for meeting high degree thermal energy need. Consumption of fossil fuels, however, causes the risks such as extinction of these resources which are already scarce, and climate change arising from high emission values. Moreover in Turkey, fossil fuel usage economically increases the dependency to imports. Faced with this situation, the cement industry opts for waste usage as an alternative energy resource. This solution not only makes it possible for the cement industry to create a relatively lower environmental impact to meet its energy needs but also provides a very efficient solution for solid waste disposal, which is the most prominent problem for sustainable city management today.
In Turkey, especially in the Marmara Region and İstanbul, the waste disposal problem has larger scale consequences. In addition to capacity problems regarding the disposal of great amounts of waste through sustainable methods, the methane gas emerging from the waste at landfill sites is a much more dangerous greenhouse gas than CO2. On the other hand, the waste usage as a fuel resource at cement plants creates an alternative even environmentally friendlier than incineration plants. Because the ash generated after incineration is used as a raw material at cement plants and returned back to the economy whereas it becomes waste at disposal facilities. For these reasons, energy recovery from wastes, which has an important potential in Turkey, is a significant solution for sustainable cities.
