PTT Group’s Operational Excellence Management System (OEMS)

IRPC has adopted an integrated environmental management system for energy, air, water, and solid waste management, utilizing the Eco Factory framework and PTT Group’s Operational Excellence Management System (OEMS) across all plant operations to enhance operational efficiency. The environmental management system is part of IRPC’s Operational Excellence Management System (IRPC OEMS), which has been certified against ISO 9001, ISO 14001, OHSAS 18001, ISO 45001, ISO 50001 and ISO 31000. In addition, the Green Turnaround concept has been integrated in our management approach to minimize impacts during annual shutdowns and turnarounds. For instance, operations are conducted in a closed system to manage the volatile organic compounds (VOCs), waste and wastewater, and odor control. The Company has also invested over 538 million Baht to develop systems for pollution prevention, environmental monitoring, efficiency improvement, energy reduction, biodiversity conservation, and fostering a low-carbon society.

Environmental Management Accounting System

To tackle the effectiveness of our environmental management initiatives, IRPC has introduced the Environmental Management Accounting System (EMA) which integrates environmental expenses, revenues and investment in accordance with the UN2001 Environmental Management Accounting Procedures and Principles to obtain accurate, adequate, and reliable data. Such data is used to plan, control, and make short- and long-term environmental management decisions to improve environmental management efficiency for day-to-day operations and reduce the cost of operations, while also creating positive impacts on the environment and society.

IRPC and IRPC Group’s affiliate have been conducting social, environmental and health impact studies for all projects which are within scope as part of the process to prepare the EIA reports, which are required by law and which must be prepared in compliance with the criteria, methodology, regulations and guidelines for EIA report preparation under the Notification of the Ministry of Natural Resources and Environment and other relevant laws.

IRPC and its affiliates had prepared Environmental Impact Assessment (EIA) and Environmental Health Impact Assessment (EHIA) which have been approved by a committee of experts and submit environmental monitoring reports to relevant government offices every six months and will be publicly available online through Office of Natural Resources Environmental Policy and Planning’s website (Thai version only).
