We use water as a coolant, solvent and cleaning agent, as well as to produce our products. We are committed to responsible water use along the entire value chain. To this end, we have set ourselves global goals.


We aim to use water as sparingly as possible and further reduce emissions to water. For this, we have set out a Group directive with globally applicable standards. Water quality and availability vary substantially from region to region. We want to introduce sustainable water management at production sites in water stress areas. In order to continue improving our processes and identify further potential for environmental protection, especially in water use, we established a globally active group of experts in 2012.

We analyze water risks in the supply chain. We offer our customers solutions that help them to purify water, use it more efficiently and reduce pollution. We started up a new water treatment chemicals plant at the site in Nanjing, China, in 2012. Furthermore, we invested in NanoH2O in 2012, a U.S. company that produces membranes which aid in desalinizing seawater.
