Significance & Commitment
Waste, especially hazardous waste, is a significant focus for the Company as improper handling can pose serious risks to the environment, employee health, corporate reputation, and license to operate. Recognizing these risks, the Company is committed to preventing and minimizing waste impacts by improving process efficiency, applying industry best practices and advanced technology, and ensuring strict compliance with laws and regulations.
Management Approach
The Company strictly follows the waste management hierarchy: prevention & minimization, reuse, recycling, other recovery operations, and disposal. Our waste management policy and standard, developed in line with international best practices and local regulations, serve as the foundation for implementation across all operations, focusing on maximizing resource utilization, minimizing waste directed to disposal, and reducing environmental impacts from incineration or landfilling.
Waste management standard is structured into 5 steps, including:
• Planning: Identify sources of waste and assess their hazardous characteristics. Define appropriate management methods and evaluate opportunities for waste prevention, minimization, reuse, recycling, and other recovery operations.
• Storage: Ensure that waste is stored in designated, well-maintained facilities. Regular inspections are conducted to uphold safety and environmental standards.
• Transportation: Implement proper waste handling protocols and maintain full traceability throughout all stages of transportation to ensure safe and lawful movement of waste materials.
• Treatment & Disposal: Maximize waste reuse, recycling, and other recovery operations. When disposal is necessary, use environmentally friendly methods and appropriate technologies to minimize impact.
• Monitoring, Evaluation & Reporting: Continuously monitor and assess waste management performance to ensure compliance with applicable standards.
For externally managed waste, the Company engages only government-authorized agencies to ensure compliance with the least environmental impact in waste transportation and disposal.
The Company develops the waste process flow that maps waste generation across the value chain: upstream, own operations, and downstream. This mapping identifies waste generation points and enables strategic planning to enhance circularity measures by identifying opportunities for waste prevention.
Internal waste volumes are systematically measured, while external waste volumes are recorded through third-party reports to uphold transparency and accountability. This comprehensive approach reinforces the Company’s commitment to sustainable waste management and environmental stewardship.
