Air Emissions Management
The cement production process includes crushing, screening, grinding and combustion processes. At these stages, dust and gas emissions may occur, which may result in environmental impacts.
We record dust and gas emission values in all our facilities with continuous monitoring systems, taking into account the current regulations in our country and world-class good practices. Moreover, we verify and control the data via measurements conducted by accredited laboratories during the periods stipulated by the relevant regulations.
In our facilities, covered conveyor systems and bag filters are used in the crushing-sieving-grinding processes beginning from the raw material preparation and transportation stages. Çimsa has closed stock areas where raw materials and products are stocked. This plays a significant role in keeping dust emissions under limits.
We measure the dust emissions of the rotary kiln chimneys resulting from the combustion process with continuous monitoring systems and report them to the relevant authorities.
Important pollutants that may arise during the combustion reaction are nitrogen oxides (NOx), volatile organic compounds (VOCs), total organic carbon (TOC), metals, hydrogen fluoride (HF), hydrogen chloride (HCl), dioxin and furan. We measure the NOx, TOC, HF, HCl parameters of the rotary kiln chimneys in all cement production facilities of Çimsa with continuous monitoring systems and report them to the relevant authorities.
We inject an ammonia solution using the Selective Non-Catalytic Reduction (SNCR) system to keep NOx emissions within limits. With the contribution of the system, we reduce the amount of nitrogen oxide (NOx) gasses generated during the combustion process.
The decrease in the clean water resources throughout the world keeps increasing the water risk every day. The fact that the water risk, which can be monitored regionally on the Aqueduct Water Risk Map, is increasing, invites all industrial organizations to more conscious consumption and sustainable resources. Although water is a direct input in concrete production, it is not the raw material of the cement production process. On the other hand, auxiliary processes such as sand and gravel washing and equipment cooling systems in cement and concrete production processes require water consumption.
The water requirement in the factories is fulfilled by wells and network resources. Reducing the water consumption, reusing the consumed water and minimizing the amount of discharged wastewater are among our main objectives as well as the main subjects of our projects.
We actively monitor the water risk of the regions where our facilities are located, and consider the potential to adversely affect production processes.
We prepare an annual Water Footprint Inventory Report to summarize and validate all of the systematic works.
Natural raw materials such as limestone, clay and schist that we require during our production activities are obtained as part of our mining activities. This situation imposes a responsibility on Çimsa to act in an environmentally, socially and economically respectful manner.
At Çimsa, we shape our approach to this issue by adopting the sub-steps of biodiversity as part of the UN Sustainable Development Goals.
At Çimsa, project activities begin before the mining site is put into operation in order to prevent any adverse impacts on the natural habitat and the environment due to the mining operations and to keep the environmental impact at the lowest level. When the mining site is designated, we define all possible environmental and social impacts, including biodiversity, as part of the Environmental Impact Assessment (EIA) process and plan the necessary measures.
We carry out the specified rehabilitation projects for the used lands with the approval of public institutions, as part of the ” Reclaiming to Nature” plans.
