General Waste, Hazardous Waste, and Chemical Spill Management
Waste Management
(Disclosure 306-1, 306-2, 306-3, 306-4, 306-5)
The Company places importance on effective and continuous waste management in order to reduce environmental impacts and support efficient resource utilization in accordance with the circular economy concept. Waste segregation measures have been established within the organization in compliance with legal requirements, and waste is disposed of in a sanitary manner through licensed service providers.
The Company communicates and promotes cooperation among employees at all levels while fostering environmental awareness to encourage waste segregation at source, reduce the amount of waste requiring disposal, and increase the proportion of waste that can be reused or recycled.
Waste Segregation Activities and Measures
- Provision of waste segregation infrastructure
The Company has provided waste bins for six categories of waste, namely general waste, recyclable waste, organic waste, infectious waste, hazardous waste, and electronic waste. These bins are installed in sufficient and appropriate numbers within office areas and operational sites. - Enhancing employees’ knowledge and skills in waste management
The Company organizes training programs to provide employees with knowledge on waste classification, proper waste segregation practices, and reduction of hazardous waste generation at source through the selection of environmentally friendly products, such as replacing fluorescent lamps with LED lighting and using rechargeable batteries to reduce hazardous waste. - Internal communication and awareness campaigns
The Company prepares communication materials to provide knowledge on waste types, proper segregation methods, waste management practices, and environmental impacts in order to continuously strengthen employees’ understanding and participation. - Waste management operations
Training is provided to housekeeping teams and relevant personnel on detailed segregation of recyclable waste at the final stage, weighing procedures, and data recording to ensure that waste management is conducted properly, transparently, and in a verifiable manner.
Monitoring, Waste Recovery, and Disposal
The Company regularly monitors waste management performance. The Safety, Health, and Environment (SHE) unit conducts random checks to verify the accuracy of recorded waste quantities for each waste category. The data are analyzed and used to calculate greenhouse gas emission reductions resulting from waste recovery, and the results are communicated to employees.
Waste that cannot be reused is disposed of properly in accordance with sanitary standards and legal requirements in order to prevent environmental and community impacts (Disclosure 306-5).
The Company records the quantity of all waste types in order to calculate the amount of greenhouse gas emissions reduced each month, as follows:
| Premises | Type | Amount (Ton / year) | Greenhouse gas emission reduction (ton-CO2eq/year) |
||||
|---|---|---|---|---|---|---|---|
| 2023 | 2024 | 2025 | 2023 | 2024 | 2025 | ||
| Head Office Building | General waste | 35.78 | 43.30 | 43.20 | 0 | 0 | 0 |
| Hazardous waste | 0.83 | 0.75 | 1.21 | 0 | 0 | 0 | |
| Recyclable waste | 3.40 | 8.13 | 6.51 | 16.06 | 41.57 | 31.769 | |
| Organic waste | 2.34 | 6.44 | 7.42 | 1.09 | 3.00 | 3.450 | |
| Infectious waste | 0.17 | 0.11 | 0.08 | 0 | 0 | 0 | |
| Operation areas | General waste | 1.22 | 0.94 | 0.51 | 0 | 0 | 0 |
| Hazardous waste | 0.73 | 5.32 | 0.42 | 0 | 0 | 0 | |
| Recyclable waste | 0.40 | 0.79 | 0.40 | 0 | 0 | 0 | |
| Organic waste | 0.60 | 1.53 | 1.17 | 0 | 0 | 0 | |
| Infectious waste | 0 | 0 | 0 | 0 | 0 | 0 | |
In addition, in 2025 the Company implemented concrete non-hazardous waste reduction initiatives focusing on waste recovery and reducing the amount of waste requiring disposal, as follows:
- Organic Fertilizer Production Project
The Company utilized 7,420.00 kilograms of organic waste to produce 1,440.00 kilograms of organic fertilizer, which was distributed to employees, building tenants, and used for landscaping within operational areas. This initiative reduced the amount of organic waste requiring disposal and promoted efficient resource utilization. - Recyclable Waste Segregation Project (Disclosure 306-4)
The Company segregated 6,506.00 kilograms of recyclable waste for proper recycling.
Through these non-hazardous waste reduction initiatives, the Company reduced the amount of waste requiring landfill disposal by a total of 13,926.00 kilograms (recyclable and organic waste), accounting for 23.84% of total waste, reflecting the effectiveness of waste segregation and waste recovery measures implemented within the organization.
Leakage of hazardous substances Management
Chemical Leakage: The Company uses chemicals such as diesel and has designated storage areas in compliance with the Ministerial Regulation on Safety, Occupational Health, and Working Environment for Hazardous Chemicals B.E. 2556 (2013). Monthly inspections of chemical storage areas are conducted. Where additional hazardous chemicals are introduced, the Company prepares and reports: Hazardous chemical inventory and safety data (Sor Or.1), Report on Measurement and Analysis of Hazardous Chemical Concentration in Workplace Atmosphere and Storage Areas (Sor Or.3), and Declaration Form for Producers, Importers, Exporters, or Possessors of Hazardous Substances under the Department of Industrial Works (Wor Or. Kor 7), in accordance with legal requirements.
In 2025, no chemical spills were reported. A contractor was engaged to monitor airborne dispersion to confirm that, in addition to physical inspections, there was no airborne dispersion that could not be detected through physical means. An annual chemical spill response drill was also conducted with relevant parties. (Disclosure 306-3)
