Ardentec

Waste Management

Waste generated by Ardentec's operations is categorized into General Industrial Waste and Hazardous Industrial Waste. All waste is centrally stored and managed, effectively tracking the source and quantity of waste generated. The Company utilizes an industrial waste declaration management system, collects internal waste disposal records, and monitors relevant data on waste generation and removal. Waste undergoes optimized classification, and non-recyclable waste is entrusted to qualified professional waste management agencies, which apply the most appropriate handling process based on the waste's characteristics. Waste handling processes are strictly controlled, with regular audits and oversight to ensure they do not result in environmental pollution. In 2025, a total of 20 waste handling process companies were audited 34 times.

In 2025, Ardentec's general industrial waste disposal totaled 704 metric tons, while the hazardous industrial waste from the headquarters and GIGA subsidiary amounted to approximately 5 metric tons. The subsidiaries in Singapore, South Korea, and Nanjing did not generate any hazardous industrial waste. In 2025, Ardentec's waste reuse rate reached 98.6%, surpassing the target of > 90%

Waste Reduction Initiatives

Reuse and Reduction of Packaging Materials

Ardentec actively collaborates with upstream and downstream partners to promote the recycling of packaging materials and enhance their reuse rate, effectively reducing waste. With the exception of certain customer-specific products that are unsuitable for packaging material reuse, Ardentec works with customers to repurpose packaging materials from incoming shipments for outbound deliveries. For example, wafer cassette boxes are professionally cleaned and reused for shipping, and cardboard boxes and wafer cassette boxes are also used repeatedly.

Paperless Project

Ardentec Headquarters has implemented measures such as process digitization and the use of tablets for data verification to reduce paper consumption. Compared to 2023, paper usage in 2025 was reduced by 34%, resulting in a reduction of 275 kilograms of CO2e in carbon emissions.

Project Highlight

Recycling and Reuse of Empty Chemical Containers

Ardentec Headquarters collaborates with qualified waste disposal and management agencies to incorporate chemical empty containers into standardized cleaning, sorting, and recycling processes, allowing used containers to be reintroduced into the industrial circular system. After proper cleaning, multi-material containers such as plastic, metal, and glass can be reused, reducing the demand for new containers and decreasing waste generation. Some waste plastics can even be recycled into marketable HDPE pellets, enhancing the value-added potential of resources and creating circular economic benefits. Meanwhile, classification and disposal as well as downstream reuse operations conducted by qualified vendors ensure that waste from its origin to final recycling complies with regulatory requirements. This prevents illegal dumping or improper handling that could cause environmental risks, while enhancing the transparency and traceability of corporate waste governance. Through this institutionalized resource and reuse model, Ardentec effectively reduces the burden of end disposal, minimizes environmental impact, and promotes the sustainable use of raw materials, demonstrating the Company's proactive commitment to circular economy and sustainable development.

Wastewater Management

The wastewater generated by Ardentec primarily consists of discharge from cooling towers used in the operation of factory air-conditioning systems and general domestic wastewater. At the Ardentec Headquarters Keystone site, monitoring facilities and standards are installed in accordance with operational regulations for wastewater-handling equipment to control wastewater prior to discharge. This ensures compliance with the Hsinchu Industrial Park Sewerage System Effluent Standards by meeting the pH, COD, and SS discharge criteria, facilitating further treatment to achieve the water quality standards required for stream discharge. As a result, the discharge from the Ardentec Headquarters does not pose any adverse impact on the biodiversity, habitats of the Xinfeng River Basin, or areas of high biodiversity located outside designated protected areas.

The wastewater generated by GIGA's subsidiary in the Hsinchu Science Park is processed through the Park's wastewater management system before being discharged into the Keya Creek. Subsidiaries in South Korea, Singapore, and Nanjing discharge wastewater that complies with effluent quality standards after treatment by their respective industrial park wastewater treatment facilities into the Hwangguji Stream and the Gaowang River, respectively. The subsidiary in Singapore discharges industrial wastewater to the government-operated NEWater Plant, while domestic wastewater is treated and subsequently discharged into the Singapore Strait.

Both Ardentec Headquarters and its subsidiaries have established contingency measures for rainwater discharge. At the headquarters, water control gates are installed at rainwater outfalls to enhance the rainwater drainage blockage prevention mechanism and mitigate the risk of pollutant discharge through stormwater channels.
