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.
- Investment in innovation or R&D to minimize waste.
Performance
- From 2020 to the end of 2024,investment in food waste treatment in Hualien Hoping Plant received a cumulative investment of NT$24.35 million.
- OYAK CEMENT Obtained Türkiye's
Zero Waste Certification. - E One Moli Corporation Plans to Implement UL 2799 Zero Waste to Landfill Certification.
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
