Since 1998, following the principles of the Plan-Do-Check-Act (PDCA) management system, our organization has implemented the ISO 14001 management system. We regularly review and systematically evaluate the processes of our activities, products, and services in order to effectively manage raw materials, processes, energy resources, waste, and resource recycling activities. Through this process, we identify the environmental impacts of our operations and discover opportunities for improvement, thereby fulfilling our social responsibilities and achieving the goal of sustainable operation.
