Waste Management
Importance and Mission
The significance of Waste Management and the Circular Economy to the Group. The Group recognizes that effective waste management and the integration of circular economy principles are fundamental to strengthening business resilience and long-term sustainability (Business Sustainability). Ensuring that all resources are utilized to their highest value, the Group is committed to “closing the resource loop”, shifting from a linear economy model of disposal toward a system that maximizes reuse, recycling, and resource recovery. This proactive approach not only supports global sustainability goals but also enhances resource efficiency, reduces operational costs, and reinforces the Group’s environmental responsibility. Through these efforts, the Group aims to deliver truly sustainable growth in renewable energy for future generations.

Goals and Performance Highlights
Goals
The Group committed to enhance the efficiency of waste management and integrate circular economy principles across its renewable energy operations. This includes reducing waste generation, increasing the recovery and reuse of resources, and promoting sustainable reuse and recycling practices. These efforts are designed to minimize environmental impacts through the following approaches :
Waste Intensity Reduction Target Reduce waste intensity by lowering the generation of both hazardous and non hazardous waste by 10% per unit of electricity generated by 2030, alongside promoting a Green Corporate Culture by raising employee awareness on proper waste segregation and encouraging the practical use of renewable resources in offices (such as reused paper).
Resource Circularity Increase the proportion of resources recovered and reused through 3Rs processes to achieve a minimum of 80 percent of total waste generated by 2030.
Zero Hazardous Waste to LandfillAchieve “zero” hazardous waste to landfill by 2030 by ensuring that all hazardous waste is managed through BOI certified treatment and disposal processes, in strict compliance with regulatory requirements. The Group will also strengthen internal communication to build employee awareness and responsibility in hazardous waste management.
Performance Highlights 2025
The Company has started a campaign to reduce the use of private cars for commuting to reduce greenhouse gas emissions. The Company also organizes tree-planting activities for employees every year.

Notes :
1 For the WINCHAI project, the Company has commenced the collection and reporting of non-hazardous waste (general waste) data from 2025 onwards to ensure the completeness of its sustainability database.
2 Hazardous waste data of 2.45 tonnes from the Winchai project, including waste generated from production and maintenance activities at the SSE and SEG projects, is excluded from this table as all waste is managed and disposed of by the O&M contractor. This exclusion is applied to avoid double counting.
Management Approach
The Group implements an effective waste management policy aligned with circular economy principles, with a commitment to enhancing waste management efficiency across the entire value chain. Circular economy practices are fully integrated into renewable energy production processes, emphasizing waste reduction at source (Reduce), reuse (Reuse), and recycling (Recycle) to preserve environmental stability and maximize resource efficiency. The Group has established control measures and operational guidelines as follows :
Waste Prevention & Source Reduction
Focus on preventive management by integrating Cleaner Production principles into operational processes to reduce both the volume and toxicity of waste at the source. This includes enhancing material efficiency, implementing strict inventory control to minimize deterioration or expiration, considering input substitution with safer alternative materials, and applying digital innovation to eliminate unnecessary use of expendable materials entirely.
3Rs Practices
Manage all processes in accordance with 3Rs principles, from systematic waste segregation and storage at the source to the application of advanced recycling technologies to return residual materials into circulation and create renewed value.
Waste-to-Value & Energy
Advance the management of biomass waste by converting it into energy or higher value products, in order to minimize disposal through non beneficial incineration or landfilling.
Hazardous & E-Waste Management
For specialized hazardous waste, particularly end of life “solar panels”, the Group engages legally registered and qualified experts to carry out disposal using safe and certified methods.
Monitoring & Compliance
Conduct systematic and continuous monitoring of waste volumes to ensure that all operational processes comply with international environmental standards and applicable laws, prevent negative impacts on communities, and support the Group’s progress toward genuine sustainability.
