Since 2018, Dyaco has implemented an "Environmental Safety and Health Policy" and a "Social Responsibility Management Manual" independently aligning with international standards set by the Responsible Business Alliance (RBA). We follow social management regulations, requiring suppliers to sign a Social Responsibility Audit Checklist, and progressively integrate the industry supply chain. Regarding environmental management, we have obtained ISO 14001 Environmental Management System certification and signed a commitment to environmental protection, energy conservation, safety, and health policies.
