✦ AI Summary
SK Hynix has operated a "Water and Wastewater Reduction TF" since 2018 to reduce water use and expand reuse.
Last year, the average daily water savings at its domestic sites were 170,000 tons, and cumulative water savings reached 303.37 million tons.
SK Hynix will present its water management achievements and future plans at the "Korea International Water Week 2026."
SK Hynix has built up a record of water resource management by reducing water use in semiconductor production and expanding reuse. SK Hynix has operated a "Water and Wastewater Reduction TF" since 2018, and the team is responsible for cutting water use in production and expanding reuse. As a result, the average daily water savings at its domestic sites last year came to 170,000 tons.
Thanks to these efforts, cumulative water savings through last year reached 303.37 million tons. That exceeded the original target of 264 million tons. Based on this, SK Hynix plans to bring cumulative savings to 329 million tons this year and has set a cumulative water-saving target of 600 million tons by 2030.
These details will be unveiled through SK Hynix's participation in the "Korea International Water Week 2026." SK Hynix will take part in the event, which runs from the 9th to the 11th at EXCO in Daegu, and will present its water management achievements and future plans.
Korea International Water Week is an international event that discusses solutions to water challenges. Governments and public institutions, companies and experts from home and abroad take part in the event. About 50 countries and 80 companies and organizations are participating this year.
SK Hynix is going beyond simply reducing water use and is improving water efficiency by increasing the share of water used in production that is reused. As a result, it is continuing to expand the scale of water reuse.
Water reuse volume rose from 47.88 million tons in 2022 to 73.59 million tons last year. That represents an increase of about 54% from 2022 to last year.
SK Hynix is expanding the scope of water reuse tailored to the process characteristics of each site. The Icheon site operates wastewater reuse facilities, and its reused water production capacity is 94,400 tons per day. The reused water produced at the Icheon site is supplied to air pollution prevention facilities and other uses.
The Cheongju site introduced externally treated sewage reuse water in 2023 for the first time in the domestic semiconductor industry. The Cheongju site is expanding water reuse by recycling used and treated water as industrial water.
Along with this expansion, SK Hynix is strengthening water resource management across the entire process from intake, use, reuse and discharge. In wastewater treatment, it applies ozone oxidation units, activated carbon and multi-stage coagulation and sedimentation systems. It is also continuing to develop technologies to further reduce pollutants and is continuing related investments.
SK Hynix set the concept for its Korea International Water Week exhibition booth as "Water Loop," and created a space that visualizes the water cycle. At the booth, the company will use video and graphics to introduce its water management activities and achievements. The presentation will include water conservation, water reuse and ecosystem preservation.
SK Hynix also plans to unveil ecosystem conservation efforts linked with the local community. It is operating the "ECOSEE Citizen Science Program" in the Anseong Stream area, and the program aims to observe ecosystem changes before and after the development of the Yongin semiconductor cluster. The program is run in a way that allows citizens to directly survey plants, birds and aquatic organisms and accumulate data.
A SK Hynix official said the company is pushing to reduce the amount of water used in semiconductor production. The official explained that the company is continuously upgrading its water resource management system to maximize the recycling of used water. The company also said it will continue to improve processes and steadily expand investment in related technologies and facilities.
