Our sustainability programs place a high priority on water conservation including improving tool efficiency and increasing water recycling opportunities.
Semiconductor manufacturing, especially wafer fabrication, is a water-intensive process. 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.
At our manufacturing sites, water mostly comes from nearby municipal facilities. The Nijmegen and Oak Hill facilities are our manufacturing sites that extract well water, representing 6% of our total water consumption.
Recycled water represented 48% of our total water use in 2022, meaning we are close to using the same amount of recycled water as non-recycled water.
As semiconductor technology evolves, manufacturing processes are becoming more complex. Smaller, faster semiconductors require more process steps to produce, which in turn increases the amount of water used for cleaning, so as to ensure product quality and process safety.
Our decade-long focus on water conservation, has emphasized the use of more efficient tools, taking advantage of opportunities to increase water recycling and finding ways to optimize processes.
Since 2012, our percentage of water recycling has increased by 16 percentage points. We currently recycle 48% of our water, and have created a task force to identify new opportunities for water recycling.
The Water Stress Index (WSI) evaluation tool is used by the United Nations and other organizations to study the relationship between water use and water availability. WSI scores are divided into four risk categories: extreme (0.0-2.5), high (>2.5-5.0), medium (>5.0-7.5) and low (>7.5-10.0).
|Wafer Fab||Assembly and Test|
|ATMC, Austin, Texas, US||5.7||Bangkok, Thailand||5.3|
|Chandler, Arizona, US||0.0||Kaohsiung, Taiwan||4.2|
|Nijmegen, Netherlands||7.9||Kuala Lumpur, Malaysia||3.4|
|Oak Hill, Austin, Texas, US||5.8||Tianjin, Mainland China||0.0|
The index is based on mean annual water stress, and therefore the seasonality of water stress is not captured. Countries and regions are assigned a rank according to their relative position in each index.
We are committed to returning water to the environment that is as clean, 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.
Our total wastewater discharge is less than our total water retrieval because a certain amount of water is lost due to evaporation landscape irrigation, and as part of non-hazardous sludge disposal.
NXP did not receive any excursions, fines or penalties in 2022 related to wastewater discharge. As of 2022, we publicly disclose our wastewater discharge in our Corporate Sustainability Report. Our total wastewater discharge is less than our total water retrieval because a certain amount of water is lost due to evaporation, landscape irrigation, and as part of non-hazardous sludge disposal.
