Management Approach

1.Policy
Operational Efficiency & Management System Roadmap 2017 – 2022 was initiated to improve IRPC’s operational performance including energy efficiency that leads to less consumptions of energy. Furthermore, IRPC commits to reduce environmental impact from its operations by initiating environmental management program covering air quality control, waste management, waste water management and spillage control, and attending Eco Factory program by the Industrial Environment Institute, the Federation of Thai.

2. Management System/Process 
IRPC adopts PTT Group’s Operational Excellence Management System (OEMS) for managing organization towards operational excellence. Numbers of project are initiated to increase energy efficiency by energy optimization projects and reduce environmental impact from air emissions control and monitoring by instrument installation, waste management by initiating waste to energy project, waste water management by ensuring compliance of water quality after treatment, and spillage control by implementation of both proactive and reactive approaches.

3. Performance 

ENVIRONMENTAL PERFORMANCE SUMMARY
(included UHV: Upstream project of Hygiene and value added product plant)

To ensure that environmental performance in 2015-2016 are comparable with historical data, the data in 2015-2016 in these below table are included new plant (UHV) that started commercial operation date in July 2016.

Materials Consumption

Energy Consumption⁽¹⁾ 

Remark: 
(1) Standards and methodologies used to calculate are based on relevant laws and regulations.

(2) Energy intensity not including energy used during major turnaround period in year 2017

Flared and Vented Hydrocarbon ^{(1), (2), (3)} 

Remark: 
(1) The amount of flared hydrocarbon is calculated accordingly to IRPC’s hydrocarbon management manual, in reference to HM31: Guide to HC Management in Petroleum Refinery Operation and HM32: Guide to Product HC management at Petroleum Product Marketing and Distribution. Management in Petroleum Refinery Operation and HM32: Guide to Product HC management at Petroleum Product Marketing and Distribution.

(2) Hydrocarbons released from production processes gathered from ACB Data (Calculated HC from the differences of feed to products as stored in SAP) and EPS data (Calculated from Feed going into the reactor in each batch 7.5% and products contain Pentane 6.6% each month)

(3) Hydrocarbons released from storage tanks and product and raw material handling, gathered from Ton VOCs of Tank calculations and Marketing& Terminal as Nm3. All reported in the VOCs Inventory.

Greenhouse Gas⁽¹⁾

Remark: 
(1) GHG calculations refer to API 2009, IPCC 2006, ISO14064-1, The Greenhouse Gas Protocol: A Corporate Accounting and Reporting Standard (Revised Edition), and GWP refers to the IPCC Fourth Assessment Report (AR4-100 year) from the Group’s subsidiaries include those from IRPC PCL, IRPC Oil Co., Ltd., IRPC Polyol Co., Ltd.,UBE Chemicals Co., Ltd (Asia), and IRPC Clean Power Co., Ltd/

(2) This does not include GHG emissions released from process vents.

(3) GHG Emission from Electricity bought from EGAT is Calculated in reference to PDP 2015 Conversion factors calculation.

(4) GHG Emission from Electricity and Steam bought from private Power Plant (Local) is calculated in reference to Allocation of GHG Emission from combined heat and power (CHP) plant Guide to calculation worksheet V.10 (A WRI/WBCSD GHG Protod. Initiative Calculation Tod)

(5) Scope 3 GHG emissions come from employee transportation and use of B5, E10, and E20 inclusion of sales and transport data, electricity loss data (PTT Tool).

(6) GHG emission intensity was calculated from Scope 1 and Scope 2 GHG emissions.
