SIGN INWe focus on conservation, recycling and high standards for wastewater treatment and discharge.
Since drastically reducing the amount of water used within our manufacturing processes is not currently feasible, we anticipate that our demand for water will increase in line with our increases in production. To reduce the amount of incoming water we consume, we focus on a mid-term goal of increasing our water recycling rate to 60% by 2027.
Semiconductor manufacturing, especially wafer fabrication, is a water-intensive process. It also creates wastewater that is discharged from our manufacturing sites.
Our water-related metrics include data from manufacturing sites only, given that the non-manufacturing impact is negligible. Many of our manufacturing sites are located in semi-arid regions that may become increasingly vulnerable to prolonged droughts associated with evolving changes to the climate, which may lead to resource scarcity.
Our decade-long focus on water conservation has emphasized the use of more efficient tools. Our Facilities and Manufacturing teams have made great strides in identifying additional opportunities to increase water recycling and finding ways to optimize processes.
A large part of our water consumption is fixed, such as the use of water for chillers, plating and cleaning. As a result of the lower loading in our factories, the normalized consumption went up. In addition to our water recycling efforts, we are looking at options to reduce the overall water consumption.
We implement projects that collect and recycle water at our manufacturing sites. This reduces the amount of incoming water consumption, reduces our reliance on local water supplies and makes our operations more efficient. Since 2015, our percentage of water recycling has increased by 14 percentage points, and 4 percentage points compared to 2023. As of year-end 2024, we recycled 55% of our water and have created a task force to identify opportunities for water recycling, so we can achieve our 2027 goal of 60% recycled water.
We are committed to returning water to the environment that is as clean as, or cleaner than, what we sourced. We employ onsite water-treatment facilities to treat wastewater outflows and ensure any chemical constituents from our wastewater that could potentially impact the environment are avoided. Our Facility Teams continuously monitor and test our water, as required by local authorities, and aim to discharge wastewater that is cleaner than what local regulations require.
Note: NXP did not receive any excursions, fines or penalties in 2024 related to wastewater discharge.

The two manufacturing sites in Texas, Austin (ATMC) and Oak Hill, received the city of Austin's 2024 award for Excellence in Wastewater Pretreatment (based on 2023 performance). The award honors significant industrial water users who exhibit environmental stewardship by proactively preventing pollution and managing wastewater discharge. This is the tenth consecutive year for ATMC to receive the award and the ninth for Oak Hill.
