Water is a central resource to all aspects of life and business, therefore water management is a crucial element to ensure sustainable use of resources and safeguard business continuity.
We understand sustainable use of water as the efficient water management practices throughout all stages of our operations, always taking into account the water needs of surrounding communities.
We emphasized the high priority of this topic in the 2015 fiscal year by endorsing the UN’s “CEO Water Mandate”. This is a special initiative of the UN Secretary-General that aims to promote a positive impact on the ongoing global water crisis by joining forces with global business leaders to advance water sustainability solutions. As an endorser, Infineon pledges to show continuing support to water preservation and conservation as seen in our environmental sustainability practices and concretely in the efficient management of water at our production sites.
According to the definition of the WBCSD (World Business Council for Sustainable Development), water shortage exists when the total volume of renewable water resources available in a given area is lower than 1,700 cubic meters per year per capita. Seen in this light, only one of Infineon’s manufacturing sites, that is Singapore, is located in an area affected by water shortages. The Singapore site accommodates mainly office and testing areas that only require a low amount of water. They used only 0.59 percent of the entire volume of water consumed by Infineon during the 2015 fiscal year.
Nevertheless, water efficiency measures have been undertaken at site, such as the installation of water-saving systems, in order to guarantee the efficient use of water in the long term. For this reason, a further building at the Singapore site was awarded the “Water Efficient Building” certificate by the local water authority “PUB” during the 2015 fiscal year.
Water consumption at Infineon:
Understanding our water balance is the first step to have a successful water management. Infineon water supply is based on in-site sources (surface and groundwater) and also from local suppliers.
In order to maintain a low level of water consumption, recycling and reuse of water within our facilities is a must. Therefore, we implement several initiatives to increase water recycling rate and use water more efficiently. For example, cooling water can be used to produce ultrapure water for manufacturing. Moreover, in some cases this ultrapure water can be also used for other purposes.
Waste water is another priority in our water management. Only after ending all possibilities of water reuse, Infineon discharge its waste water directly or indirectly depending on its quality, local conditions and official permissions.
