Waste Management | Sustainable Environment

Waste Management

Chipbond Technology complies with the Ministry of Environment's regulations on waste disposal and implements waste reduction, reuse, and proper treatment measures annually based on the ISO 14001 Environmental Management System. In addition to ensuring that the Company's operational waste management complies with regulatory and ISO standards, Chipbond also assesses waste-related impacts across the upstream and downstream value chains. Upstream, green procurement processes are implemented to avoid hazardous substances in raw materials. Downstream, the company has introduced hazardous substance process control (IECQ-QC 080000) and a vendor audit mechanism for waste disposal, treatment, and recycling, minimizing environmental hazards.

Wastewater Treatment and Resource Recycling

Through a product life cycle perspective, Chipbond continuously reviews and optimizes waste categorization and recycling processes to achieve energy saving, waste and carbon reduction goals. Waste management roles are clearly defined within each site. All sites are staffed with certified waste management personnel. To minimize the risk of leakage during manual handling, wastewater is collected via segregated pipelines under safe operation principles. Solid waste is sorted at the source and temporarily stored in designated waste storage areas based on its nature before being removed, treated, or recycled by certified vendors authorized by the Ministry of Environment. Chipbond prioritizes environmentally friendly reuse methods for waste treatment, followed by recycling. Incineration or landfill is considered only when recycling or reuse is not feasible. All waste generated is outsourced to off-site vendors for proper disposal.

2025 Implementation Results of Major Projects：

611.624 metric tons of waste solvents were generated, with 536.274 metric tons successfully recycled, achieving a solvent recycling rate of 87.68%.
By working with applied material service providers, the waste silicon sludge generated from the grinding process water treatment system at the Zhanye Plant and Kuang-Fu Plant were recovered and processed into silica sand mortar and upgraded to recycled materials for high-value products. 111.54 tons of silicon sludge was recovered in 2025.
The copper-containing sludge from Nanyi Plant is processed by professional and qualified vendors for copper metal recovery, enabling the sustainable recycling of resources. In 2025, total of 263.34 tons were successfully recycled.
Chipbond created the "Tray Scrap Recycling and Remanufacturing Project". We recycled the scraps and waste materials generated in the production process, crushed them and mixed them with new raw materials to make recycled plastics, and reintroduced them into the process to reduce plastic waste and dependence on virgin plastics. The amount of defective materials invested in 2025 was 35,687 KG, and the recycled plastic input ratio was 23.48%.
Waste hydrofluoric acid generated by Yanfa Plant is collected and transferred to a specialized recycling contractor for conversion into calcium fluoride filter cake through pH neutralization, crystallization, and dewatering processes. The material is subsequently dried and pelletized to produce synthetic fluorspar. In 2025, total output reached 33.29 metric tons.

In 2025, total waste generation amounted to 2,870.041 metric tons, with hazardous waste totaling 1,318.48 metric tons and accounting for 45.94% of the total. Compared with the nearly equal distribution of hazardous and non-hazardous waste in 2023, the waste structure has shifted toward a predominance of non-hazardous waste (54.06%). This change indicates that the proportion of high-pollution waste sources has been progressively reduced and brought under control. The Company continues to promote resource recovery and recycling. In 2025, the waste recycling growth rate (29.37%) exceeded the waste generation growth rate (24.31%), achieving a decoupling of resource utilization from business growth. Affected by changes in production output, waste generation per NT$1 million of revenue was 0.134 metric tons, representing an increase of 18.18% compared with the previous year.
