Waste Management

Management Approaches
In accordance with ISO 14001 certification, waste management regulations are established at each operation location
All waste from TCC's plants is non-hazardous, and is treated in a non-harmful manner in accordance with regulations

Target
Achieve the "Zero Waste" goal of minimizing waste generation and maximizing resource recovery and reuse
Cement plants set a goal in 2024 to achieve 100% conversion of waste into renewable resources, striving for "innocuous treatment and resource utilization" practices

Treatment Process
General/Industrial waste: Recycled through the treatment with the high temperature in the rotary kiln process an reuse/Treated by certified vendors
Valuable industrial wastes: Recovered by qualified third-party clearing agencies
