Ecological Sustainability Management
EGAT recognizes that biodiversity is a critical foundation for global sustainable development and ecosystem services, and that changes in biodiversity may impact the environment, society, and the Company's long-term operations. In response to the direction set by the United Nations' Kunming-Montreal Global Biodiversity Framework (COP15), we have publicly announced our Biodiversity and Zero Deforestation Commitment. By implementing our Sustainable Development Best Practice Principles, Environmental and Energy Policy, Supply Chain Sustainability Policy, and Supplier Code of Conduct, we actively engage with stakeholders and strive to minimize negative impacts on natural ecosystems, moving toward the goal of achieving a "Net Positive Impact (NPI)" on biodiversity.
Meanwhile, the Company is monitoring the development of the Taskforce on Nature-related Financial Disclosures (TNFD) and plans to adopt its framework. By applying the recommended LEAP approach, we aim to clarify the dependencies and impacts between our operations and natural capital, enabling us to develop the most effective strategies for reducing ecological impact and promoting ecological restoration, thereby realizing our vision of shared growth between our operations and nature.
Adopting Plant-Based Cutting Fluids to Protect Biodiversity
Regarding the connection between biodiversity and nature-related issues, the Company actively optimizes its processes and considers the use of natural resources, ecotoxicity risks, and environmental impacts when selecting certain process materials and raw materials. We have introduced a plant-based cutting fluid developed by MCM. The product's core raw materials are derived from sustainable agricultural plant oils and integrated with waste cooking oil regeneration technology, ensuring raw material traceability and a commitment to resource circularity.
Compared to traditional mineral oil cutting fluids, these products offer the following associated benefits in reducing potential environmental and ecological impacts during the manufacturing process:
Reducing Ecotoxicity Risks:
The product is fully biodegradable, and its formulation reduces the use of specific ecotoxic chemicals, helping to mitigate the potential toxic impact on aquatic ecosystems, soil microorganisms, and surrounding environments during use or upon entering the environment.
Reduction of VOC Emissions:
Significantly reduces VOC emissions during the manufacturing process, helping to improve workplace air quality and reduce the indirect impact of air pollution on the surrounding natural environment.
Indirect Reduction of Waste Flow:
The product's longer service life reduces replacement frequency, thereby decreasing the volume of waste cutting fluid and lessening the environmental impact of downstream waste disposal.
Pioneering the Use of Eco-Friendly Aerospace Cleaning Agents to Protect Aquatic Ecosystems
Nonylphenol ethoxylates (NPE) and dichloromethane (DCM) are widely used in industrial cleaning, but both are significantly harmful to the aquatic environment. Once released into the environment, NPE degrades into nonylphenol, an endocrine disruptor that severely interferes with the endocrine systems of aquatic organisms. Due to its bioaccumulative nature, it poses an even greater hazard to fish-eating migratory birds. Methylene chloride is a toxic chemical substance that not only affects the health of operators but can also be directly toxic to aquatic organisms if it leaks into the environment.
To protect the aquatic environment surrounding EGAT and important downstream wetlands, the company collaborated with Cee-Bee, a major international chemical supplier, in 2025 to complete the technical substitution and verification of several maintenance and cleaning agents. This resulted in the successful implementation of NPE-free products, such as degreasers, descalers, and airframe cleaners, across all aircraft engine and airframe maintenance processes.
More than a decade ago, the Company adopted eco-friendly, dichloromethane-free paint strippers and replaced them with non-toxic formulations. For certain operations, we also use biodegradable products, which substantially prevent toxic substances from harming the ecological environment.
EGAT complied with the Ministry of Environment's restrictive regulations one year ahead of schedule. While ensuring uncompromising maintenance quality, the Company has significantly minimized the potential environmental impact of its aircraft engine and airframe maintenance processes. By mitigating ecological impacts at the source, the Company is leading the domestic aviation maintenance industry toward a green transformation.
