Our environmental program helps NXP conserve vital water resources and increases our efficiency. We monitor the environmental impacts using a sustainability management system which measures and tracks the water consumption from our manufacturing sites.
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.
At our manufacturing sites, water mostly comes from nearby municipal facilities. The Nijmegen facility is the only site where we use well water, representing 6% of total consumption.
Our 2021 results show that we are close to using the same amount of recycled water as non-recycled water.
The manufacturing processes used to produce semiconductors are becoming more complex. Smaller, faster semiconductors require more processing steps to produce, which in turn increases the amount of water used for cleaning, ensure product quality and process safety. Our manufacturing sites conduct water conservation initiatives, such as improving processes and reusing water.
Since 2011, our rate of water recycling has increased by 17 percentage points.
Water stress index 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). Countries are assigned a rank based on their relative position in each index. The index is based on mean annual water stress, and therefore the seasonality of water stress is not captured.

Our sites comply with local permits when discharging wastewater. This includes releasing wastewater into municipally owned treatment systems.
Removing pollutants at the source minimizes our impact. We use onsite water-treatment facilities to treat wastewater, so the water we discharge is cleaner than the water we receive. These onsite facilities continuously monitor and test water, as required by local authorities. All sites surpass local permitting thresholds.
We estimate that 95% of our water consumption is treated and discharged. We attribute the 5% difference to evaporation.
NXP did not receive any excursions, fines or penalties in 2020 related to wastewater discharge.
