Waste Treatment / Material Efficiency

Waste Management

Management Approaches

  • In accordance with the ISO 14001 environmental management system, waste management procedures are established at each operation location to implement waste sorting and management.
  • All waste processed on-site at TCC's facilities is non-hazardous and is treated in compliance with relevant regulations.
  • Investment in innovation or R&D to minimize waste, with waste reduction training and awareness for employees.

Performance

  • 100% of plants in Türkiye obtained Zero Waste Certification (OYAK Cement).
  • In 2025, cement plants of the Cement and Environmental Protection Business (Asia) converted 100% of on-site waste into renewable resources and energy, meeting the target.

Target

  • Achieve the "Zero Waste" goal of minimizing waste generation and maximizing resource recovery and reuse.
  • Cement plants of the Cement and Environmental Protection Business (Asia): convert 100% of on-site waste into renewable energy and resources.
  • OYAK Cement: reduce total waste by 15% year-over-year.

Treatment Process

General/Industrial waste

Recycled through high-temperature treatment in the rotary kiln process and reused / Treated by certified vendors

Valuable industrial wastes

Recovered by qualified third-party clearing agencies

System Integration & Target Setting

TCC's global operating sites adhere to the ISO 14001 environmental management system (EMS) and our “Waste Management Regulations” to implement waste sorting and management. We establish step-by-step waste reduction targets to systematically guide our efforts and enhance the overall resource circulation efficiency across the corporation.

AAct

Employee Training & Continuous Improvement

We continuously conduct capacity-building programs, providing training sessions on ISO systems that cover waste management to enhance circular economy awareness and actions among all employees. Simultaneously, we promote initiatives such as green office practices and green purchasing to achieve continuous environmental improvement.

Co-processing & Circular Reuse

Sorted and crushed industrial waste and general municipal waste are sent to our cement plants to be co-processed as alternative fuels and raw materials through high-temperature cement kilns. Valuable metals that cannot be reused on-site are outsourced to qualified recycling organizations for downstream reuse, ensuring a legal and fully traceable waste flow.

CCheck

Systematic Audits & Opportunity Identification

We periodically conduct waste sorting audits and inventory checks to track waste generation sources. By integrating ISO management systems, we systematically evaluate potential areas for waste reduction and circular reuse, actively identifying energy and resource improvement opportunities.
