Water Resource Management

Because of influence of climate change in recent years, the distribution and utilization of water resources have become challenges that must be addressed. Especially, factories of the company are located in the southern region with distinct rainy and dry seasons, making water resource management and countermeasures against water conservation and water scarcity even more critical. The company has made water conservation a primary policy and put it into action.
All employees are committed to cherishing every drop of water. Additionally, we are planning to actively promote water recycling measures and conduct assessments of our water usage in the future to make JLT an excellent company in water resource management.
JLT is actively engaged in water resource management. In addition to implementing water-saving measures for domestic use, the company introduced a wastewater recycling system（TMF） in the plating process of our third factory construction project to recycle the wastewater generated during production in 2021. In November 2024, the company completed the installation of a reclaimed water recovery system at second factory to recycle wastewater from the acid cleaning process. However, since the system had only been in operation for about one month, the amount of water saved was limited to 103 metric tons. Overall, the water reuse rate in 2024 decreased from 23.43% in the previous year to 16.64%, primarily due to adjustments in plating capacity at third factory, which led to a reduction in reclaimed water volume. As a result, the total volume of recycled water within the plant dropped from 45,489 metric tons in 2023 to 25,744 metric tons in 2024.

JLT is located in the Nanzih Technology Industrial Park (Formerly Nanzih Export Processing Zone) in Kaohsiung, and the water resource risk in this area is considered low. The water consumed in our factories is sourced mainly from the Cheng Ching Lake Reservoir. In 2024, the total water intake was 128,939 million metric tons, which is a decrease of approximately 4.9% compared to the total water intake of 135,583 million metric tons in 2023. The main reason for this reduction is a slight decrease in production. The water use is as shown in the table below:

Discharge of Wastewater

JIH LIN ensures that all wastewater produced within the factory is treated with appropriate sewage facilities to ensure that the discharged water complies with current process zone’s rule and regulation. Regular third-party inspections are commissioned to monitor water quality from an external perspective. The company gradually strengthens or replaces wastewater treatment equipment to effectively enhance the efficiency of wastewater treatment. Comprehensive wastewater treatment training is provided also to staffs. 
JIH LIN commissions qualified testing organizations every six months to collect samples and inspect the discharged water, and then duly review and enhance wastewater treatment work on facilities. Those ensure that the water quality exceeds the current environmental regulatory discharge standards and reduces environmental pollution impact. In 2023, factory 1 was affected by a fire incident at a neighboring factory and ceased wastewater treatment operations, resulting in no monitoring records. However, the effluent water quality at factories 2 and 3 complied with regulatory discharge standards. The company's wastewater discharge standards are as follows:
