The Company has placed top priority on waste management since it is the best practice for natural resources conservation in order to reduce wastes arisen from our operations to a minimal and able to lessen waste disposal costs. For the power generation business, aside from non-hazardous and hazardous wastes, there are also by-products generated from fuel combustion and air quality treatment procedures, such as ashes and gypsums, which can be used for creating added values from selling them to mix with construction materials. The company also pays attention to hazardous waste management because if there is a leak or improper disposal, may affect the environment and surrounding communities.

Under the environmental policy, the Company has waste management guidelines summarized as follows:

Waste Categories	Examples	Management Approach
Nonhazardous wastes	• Papers and office equipment • Metal scraps materials and equipment as well as packaging • Household wastes • Organic wastes generated from tree trimmings and mowing in the area	• Reducing consumption • Storing and classifying for reuse and recycling.
Hazardous wastes	• Used oils, lubricants • Chemicals used to improve water quality and other chemicals including packaging • Electronic wastes such as solar cells that will be existing in the future	• Consumption reduction • Looking for opportunities to transforming the hazardous wastes to those being able to treat and reuse better • Reducing packaging usages by transporting and installing hazardous wastes in the chemical storage tanks • Storing and classifying wastes for reuse and recycling • Developing measures to prevent and handle waste leakages and in the event of emergency • Transportation, disposals and sales for recycling must meet the standards set by laws • Conducting a study on material parts separation for recycling and eliminating the expired solar cells in the future at the project’s beginning stage • Delivering wastes for disposal by the certified external parties
Ashes and gypsums	• Fly-ashes • Bottom ashes • Synthetic gypsums	• Fly-ash sizes separation corresponding to the customers’ needs and the market demand • Exploring the market to sell fly ashes, bottom ashes and gypsums as materials for construction • Arranging the areas to instore ashes and gypsums appropriately and adequately • Transporting ashes and gypsums for disposals by the certified external parties

Performance

• None of hazardous wastes disposed by landfills
• Hazardous wastes eliminated by reuse or recycling accountable for 59%
• Fly ashes eliminated by reuse or recycling accountable for 100%
• Synthetic gypsums eliminated through reuse or recycling accountable for 100%
