Water management

Primax Group's production processes are predominantly assembly-based and do not require significant water consumption. Most water use is for domestic purposes and certain facility operations, such as kitchens and cooling towers. According to assessments, the Group's primary water sources are tap water, with no use of rainwater or groundwater. All water consumption complies with local regulations, and withdrawal volumes do not have a significant impact on water resources. Nonetheless, Primax continuously monitors water usage at production sites and is committed to reducing consumption. To strengthen water resource management strategies, all nine major operating sites have obtained ISO 14046 water footprint verification statements and developed water balance diagrams for each factory to support more effective water conservation strategies.

As part of its annual assessment of physical climate risks, Primax conducts water stress risk assessments using the World Resources Institute's Water Risk Atlas to simulate scenarios in different regions and evaluate the potential impacts of water stress on actual business activities. In 2024, the Group evaluated water stress risks at 21 sites. Most locations were assessed as low to medium risk, with only a few sites located in high water stress areas (such as Thailand, Kunshan, and Beijing). Primax has developed adaptation and management measures to address these risks, as detailed in the 2024 TCFD Report.

In 2024, Primax Group's total water consumption was 771,151m3, with a water intensity of 13.24 m3 per NT$1 million revenue. This represented an increase of 2.60% compared to 2023, but still a reduction of 4.19% relative to the 2020 baseline. While implementing energy conservation measures across facilities, Primax also monitors water use and has taken concrete actions to reduce unnecessary consumption. At Primax (Dongguan) and Tymphany (Huizhou), reclaimed water systems have been implemented to treat and reuse process wastewater. The filtered reclaimed water is used for landscaping irrigation and toilet flushing within the facilities. At Primax (Chongqing) and Primax (Thailand), reverse osmosis (RO) wastewater recovery systems are in place to reuse reclaimed water in cooling towers and for domestic purposes. In 2024, the total volume of reclaimed tap water reached 57.35 million liters, accounting for 7.44% of the Group's water consumption. This approach reduces raw water withdrawals and wastewater generation, thereby lowering environmental impacts.
