Waste optimization initiatives include the at-source reduction of wastewater destined for disposal from tank cleaning in the oil refinery area, which involves reviewing the wastewater management process and the wastewater quality and changing the disposal method by diverting to an internal treatment system instead of external disposal. As a result, GC has been able to reduce wastewater disposal by over 140 tons. Green turnaround projects include removing heat insulation with minimal damage, storing heat insulation in appropriate containers, and preparing storage areas to keep the insulation material dry, all of which align with the concept of the circular economy. In 2023, GC was able to reuse heat insulation materials at an average rate of over 50%. GC has carried out a zero industrial waste to landfill project since 2015. The project has since been expanded into an initiative to reduce and divert office waste from landfills to refuse derived fuel (RDF) production. Air Quality Control GC has carried out projects to control air pollution within both operation areas and fence lines to comply with legal requirements and international standards. The Company also works with the government sector as a representative of the petrochemical industry to establish environmental management guidel ines as wel l as appl ies innovation through an environmental taskforce to maximize effectiveness, with the ultimate goal of establishing a strong environmental management network. Relevant initiatives undertaken are as follows. GC has established guidelines for controlling the release of benzene vapors and 1, 3-butadiene in alignment with the existing Code of Practice (CoP) in collaboration with five petrochemical industrial estates and a port in Map Ta Phut. GC has joined the environmental taskforce of the Petrochemical Group under the Federation of Thai Industries to study predictive emission monitoring systems (PEMs) and ensure that GC’s envi ronmental management is in compliance with the law as well as to apply innovative pollution reduction technologies to maximize efficiency through the cooperation between the government and petrochemical operators. Water Management GC has ensured its preparedness for water crisis brought on by climate change and strives to contribute to the achievement of the UN SDG 6: Clean Water and Sanitation. To this end, it focuses on sustainable water management both internally and externally as detailed below. Internal: GC has appointed a Water Management Taskforce to oversee water management and prepare measures to effectively address water crisis and maximize water efficiency in production in a timely manner both in the short and long term. In addition, GC has carried out projects to optimize water efficiency in production, such as the utilization of the wastewater reverse osmosis (WWRO) technology to treat and recover wastewater for use in the manufacturing process, which can reduce the consumption of raw water by over 2 million cubic meters on average per annum. External: GC has joined the Keyman Water War Room, which consists of the Royal Irrigation Department, the Industrial Estate Authority of Thailand, the Provincial Waterworks Authority, the Federation of Thai Industries, and business owners, to track the water situation in source water reservoirs as well as establish and implement plans to achieve sustainable water management measures in the eastern region. 3.2) Proactive Environmental Management Towards Net Zero GC places emphasis on addressing and mitigating climate change impacts and has set the goal of achieving Net Zero emissions for scope 1 and 2 by 2050 to maintain its climate leadership in accordance with the assessment criteria of the Carbon Disclosure Project (CDP). To this end, it has adopted an integrated single platform for environmental data and applied data from environmental impact assessments across product life cycles in its Water Management For More Information: https://sustainability.pttgcgroup.com/en/environment/sustainablewater/sustainable-water-strategy-target-and-performance Air Quality Control For More Information: https://sustainability.pttgcgroup.com/en/environment/air-quality/ emissions-reduction-target-and-performance 198
