Water Resource Management

Water Resource Management Use of Water Resources

As for use of water resources, in addition to the domestic water used in the office area, most of the water resources are used for the grinding, cutting and tape manufacturing processes. As the extreme climate has occurred more frequently as a result of the climate change, the drought and rainstorm have become a climate risk concern for the operation of a business in recent years.We improve the efficiency of water resources by implementing integration of water resources, recovery of wastewater, saving measures, and emergency response mechanisms to reduce the impact on operating activities caused by unstable water resources.

 

 

Water Resource Management and Recycling The main sources of production wastewater in Chipbond are the wastewater containing silicon powders produced from the production of wafer bumps, grinding and cutting, the washing wastewater produced from the tape production, and the following listed in order: the acidic and alkaline wastewater, organic wastewater, domestic sewage and heavy-metal wastewater. To reduce our dependence on raw water and wastewater drainage, we spare no effort to improve the recycling rate of process water. First of all, we use the high-efficiency equipment to perform water recycling and the treatment of pollutants in water according to the types of wastewater produced from the operating process. Next, the recycled water is piped and collected to the wastewater treatment facility for sorting and management, so as to put the reusable water into use of production or for other secondary purposes.

 

The Results of the Key Water-Saving Initiatives Implemented in 2025

All plants regularly clean water systems with membrane pipes and replace unsuitable components to preventreduced water production efficiency and avoid unnecessary water consumption.   This year, the recycled water volume from the dicing and grinding process recycling system was 726.535 ML. However, due to increased dicing and grinding process activities, the recycling rate decreased by 2.51% compared with the previous year. To address this issue, an improvement plan has been developed, and system optimization is scheduled for 2026 to achieve the Company's established water resource management objectives.

Overall, Chipbond Technology's total water consumption in 2025 was 3,328.1844 ML. Due to increased production output and enhanced process quality requirements during the year, water consumption increased by 8.59% compared with the previous year. Water sources included 1,996.2074 ML of municipal water, 0.12 ML of groundwater, and 1,331.857 ML of recycled process water.
