Waste Management
Importance and Mission
The significance of Waste Management and the Circular Economy to the Group. Waste management and the circular economy are at the core of the Group’s mission to maximize resource efficiency, minimize waste, and promote material reuse wherever possible. The Group focuses on the principles of reducing consumption, reusing, and recycling (Reduce, Reuse, Recycle) to extend the lifespan of materials and reduce environmental impact. In the case of biomass energy, we actively promote the beneficial use of by-products, such as converting biomass ash into soil conditioners to improve acidity levels, with approval from the Agricultural Research and Development Division, Department of Agriculture. This practice reduces the volume of waste that needs to be disposed of. Through innovative waste management strategies, responsible sourcing of raw materials, and strong recycling initiatives, we are committed to closing the resource loop in our operations. This approach not only supports global sustainability goals but also improves resource efficiency, reduces costs, and strengthens our environmental responsibility, ensuring the long-term sustainability of our renewable energy for future generations.
SDGs in the Waste Management
Goals and Performance Highlights
Goals
Increase recycling rates through the 3R process (Reduce, Reuse, Recycle) to at least 80% of total waste by 2030.
Reduce general waste within the organization by 10% by 2030 – through awareness campaigns, improved segregation practices, and increased use of recycled paper.
Achieve zero hazardous waste sent to landfills by 2030 - by ensuring safe disposal through BOI-compliant methods and targeted employee training.
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
Waste management is carried out effectively and aligned with the principles of a circular economy, focusing on reducing waste at the source (Reduce), reusing (Reuse), and recycling (Recycle) to optimize resource utilization. Strict control measures are enforced throughout every process, from the proper sorting and storage of waste, to reusing by-products, utilizing modern recycling technologies, and managing biomass waste by converting it into energy or valuable products. The Group aims to minimize waste disposal through incineration or landfilling. For hazardous waste, the Group contracts specialized and registered entities that are authorized to dispose of waste correctly, such as solar panel waste.
In addition, the Group continuously monitors and tracks waste quantities, ensuring compliance with international environmental standards and relevant regulations. This approach helps guarantee that operations do not negatively impact the environment or local communities, while steering the organization toward a sustainable circular economy.
