Energy Management

At Akçansa, we consider energy management a critical strategic priority, both for the efficient use of natural resources and for achieving our carbon reduction targets. All of our cement plants operate under the ISO 50001 Energy Management System, through which we maintain a continuous focus on reducing energy consumption and enhancing efficiency. In this context, we carry out equipment upgrades, process optimization projects, and modernization investments that result in significant savings across our production processes. In 2024, our energy efficiency initiatives yielded a total energy saving of 32,523 GJ.

Çanakkale Fabrikamızda kurulu 15 MW kapasiteli atık ısı geri kazanım tesisi ve 2,5 MW kapasiteli rüzgar türbini ile Akçansa’nın toplam elektrik ihtiyacının %8,6’sını kendi yenilenebilir kaynaklarımızdan sağladık. 2023 yılında tüm elektrik tüketimimizi yenilenebilir enerji ile karşılayarak I-REC Uluslararası Yenilenebilir Enerji Sertifikası ve Ulusal Yenilenebilir Enerji Kaynak Garanti Belgesi (YEK-G) almıştık. 2024 yılında da bu yaklaşımı sürdürerek yenilenebilir enerji kullanım oranımızı %100 olarak koruduk. Bu sayede yaklaşık 296.562 ton CO₂e Kapsam 2 emisyonunun önüne geçtik.

We adopt energy-efficient solutions not only in our production processes but also in the buildings where we carry out our operations.

We are expanding our renewable energy investments to meet our energy needs through clean energy sources. At our Çanakkale Plant, we generated 8.6% of Akçansa’s total electricity consumption from our own renewable sources via a 15 MW waste heat recovery system and a 2.5 MW wind turbine. In 2023, we sourced 100% of our electricity from renewable energy, supported by I-REC (International Renewable Energy Certificate) and YEK-G (Renewable Energy Resource Guarantee Certificate) certifications. Continuing this approach in 2024, we maintained a 100% renewable electricity usage rate, thereby avoiding approximately 296,562 tons of CO₂e in Scope 2 emissions.
‍
To improve the efficiency of our waste heat recovery systems, we collaborated with specialized consultancy firms in 2023 to develop a set of new actions and a roadmap. As part of the first phase of the roadmap, we made modifications to the AQC1 and AQC2 boiler inlet pipes during scheduled kiln revisions. The second and third phases are planned for future years and will be included in our CAPEX investment plans. With these investments, we aim to increase the efficiency of our WHR systems and recover more energy. In 2025, we plan to carry out turbine and general system maintenance as part of this roadmap.
‍
In addition to our production operations, we also adopt energy-efficient solutions in the buildings where we conduct our activities. We prefer high-efficiency technologies in lighting and HVAC systems to reduce the environmental footprint of our operations. In 2024, our Akçansa Port Office project located at the Ambarlı Port in Istanbul was awarded the LEED v4 Silver Certification. Throughout this process, we integrated sustainability principles into both the design and construction phases, creating a modern and environmentally conscious workplace.

Total Energy Consumptıon (MWh)

Energy Intensıty (MWh/ ton cementıtıous)

In 2024, our total energy consumption increased by approximately 2.5% compared to the previous year, reaching 7.2 million MWh. This rise was primarily due to an improved calculation methodology that now includes energy consumption from logistics operations. Despite this increase, our energy intensity per unit of production remained consistent with 2023 levels. Moving forward, we aim to expand our energy efficiency initiatives and continuously improve our performance.

Through the 15 MW waste heat recovery plant and the 2.5 MW wind turbine installed at our Çanakkale Plant, we met 8.6% of Akçansa’s total electricity demand from our own renewable energy sources.

We are focused on reducing fossil fuel consumption and minimizing the environmental impact of our production processes, recognizing the cement industry's high energy requirements. During clinker production—a key phase in cement manufacturing—the thermal energy demand is traditionally met through fossil fuels. However, by using alternative fuels derived from waste, we reduce both carbon emissions and environmental impact.
‍
Alternative fuels not only lower fossil fuel dependency but also contribute to improved waste management by enabling the recovery of difficult-to-dispose materials. This approach limits landfill use, helping to prevent greenhouse gas emissions and pollution associated with waste storage. Since combustion takes place at 1,500°C, no additional pollutant gases are generated during the process.
‍
According to the Low Carbon Pathway for the Turkish Cement Sector¹³ report published by the Republic of Türkiye’s Ministry of Industry and Technology, the share of alternative fuels in the sector's total fuel consumption reached 10.6% in 2023. Recognizing their vital role in tackling climate change, we aim to increase our use of alternative fuels, consistently surpassing the industry average to support the transition to a low-carbon economy.
‍
In 2024, our alternative fuel usage rate was 20.3%, down by 3 percentage points from 23.3% the previous year. This decline was primarily driven by fluctuations in global fuel prices, inflationary pressures, and limited access to waste materials. Our plant-specific usage rates were 19.3% at Büyükçekmece, 19.1% at Çanakkale, and 33.1% at Ladik.
At our Büyükçekmece plant—the first in Türkiye to obtain an alternative fuel license—we continue to convert sewage sludge from Istanbul’s Advanced Biological Wastewater Treatment Systems into energy. In 2024 alone, we recovered approximately 64,000 tons of domestic sewage sludge for energy generation.
‍
Our alternative fuel portfolio includes industrial waste, sewage sludge, liquid waste collected from ships, and end-of-life tires. These sources enable us to replace fossil fuels while also conserving natural resources. In 2024, we utilized 248,000 tons of waste as alternative fuel, contributing to the circular economy.
‍
We also advanced our efforts in biomass-based alternative fuels in 2024. At our Çanakkale plant, we converted 22,000 tons of biomass waste into energy, contributing to a reduction in fossil fuel usage and carbon emissions. Additionally, we launched a project to develop a shredded tire feeding system at our Ladik plant.
‍
We aim to increase our alternative fuel usage rate to 35% by 2030. In line with this target, we are focusing on high-biomass-content fuel sources to further reduce fossil fuel consumption and accelerate our transition to low-carbon production.

At Akçansa, we continue to develop environmentally responsible, high-efficiency, and innovative products by leveraging advanced technologies. Through this approach, we aim to add value to the cement and ready-mixed concrete industries while reducing the environmental impacts of our production activities, thereby contributing to a more sustainable future. With our sustainable product range, we not only support the industry but also maximize customer satisfaction through our commitment to superior quality.
‍
In line with our 2030 Sustainability Targets, our R&D department continued its efforts in 2024 to develop low-carbon cement and concrete products. By 2030, we aim to make all our cement and concrete products sustainable, reduce the carbon emissions of our domestically sold cement products by 20%, and decrease our carbon emissions by 120 kg per ton of cement through the production of new cement types.
‍
Our Sustainable Product Initiative, launched in 2022, enabled us to bring together our low-impact cement and concrete products under the “Green Formulation” concept.

In this context, we categorize our sustainable cement products under “Green for Cement” and our low-carbon concrete products under “Green for Concrete.”
‍
Under the “Green for Cement” category, we offer Actioncem, a low-carbon cement with reduced CO₂ emissions; Solidcem, a solution with enhanced resistance to environmental factors; and Duocem, a product that provides high durability. Within the “Green for Concrete” category, we offer Ecocrete, a new generation of ready-mix concrete that targets the lowest possible carbon footprint through the use of sustainable technologies. In addition, we continued to offer innovative solutions in 2024 through our specialized ready-mix concrete products—Performix, Solidmix, Hidromix, A+Beton, 100+Beton, Yolbeton, and TunnelMix—which are developed to meet specific customer and project requirements, and stand out with their sustainability and long service life.
‍
In 2024, the sales volume of our sustainable products reached 33.11%, reflecting a 23% increase compared to the previous year. Additionally, sustainable ready-mixed concrete products accounted for 34% of our total ready-mix sales. These products are produced under the Ecocrete brand and have a carbon footprint that is at least 15% lower than standard reference products.
‍
We aim to strengthen our trust-based relationships with stakeholders by transparently sharing the environmental impacts of our products throughout their entire life cycle. Through our life cycle assessment (LCA) project launched in 2020, we prepared the first Environmental Product Declarations (EPDs) in Türkiye’s ready-mixed concrete sector. Furthermore, in 2022, we published EPDs certified by The International EPD® System for our ASTM C150 Type I/II Portland cement and ASTM C595 Type IL Portland-limestone cement products. In 2023, we updated the EPDs for all our ready-mixed concrete products. These documents help our customers better understand the environmental impact of the concrete they use and provide advantages in green building certification processes such as LEED, BREEAM, and Green Star.
‍
In 2024, our Büyükçekmece, Ladik, and Çanakkale plants took an important step in line with the Regulation on Promotion of the Use of Green Cement with Low Carbon Emissions in Public Procurement Contracts, published that year. Accordingly, we obtained green cement certification for our cement products that fall within the scope of the regulation.
