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 2014 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 “World Business Council for Sustainable Development” (WBCSD), water stress begins with an available total amount of renewable water resources of less than 1,700 cubic meters per person in the population per year. We used the “Global Water Tool Version 2015” of the WBCSD to perform a risk analysis at country level. The results show that only our manufacturing site in Singapore is located in a water stress area. This site consists primarily of office and test operations with a comparatively low level of water consumption. Although during 2016 fiscal year only 0.62 percent of our total water volume was consumed there, we implemented measures to ensure efficient water use at site as well. Two buildings at site have been awarded the “Water Efficient Building” certificate of the local water authority “PUB”. Since March 2016 a technical innovation has made it possible to make more efficient use of the water in the cooling towers, reducing annual water requirements by more than 4,500 cubic meters.
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.
