Use of water

  • Gold-level certification for the application of the European Water Stewardship standard at the site in Tarragona, Spain
  • Construction of plants to improve wastewater analytics at sites in Geismar, Louisiana, and Ludwigshafen, Germany
  • Commitment to protecting Rhine River at Ludwigshafen site when set temperature limits are exceeded

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 explore measures for implementing sustainable water management at sites in water stress areas.

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. As a partner in a large-scale project commissioned by the national water company, we have been installing special ultrafiltration technology in Accra, Ghana, for seawater desalination in the creation of drinking water since 2013. We started up a new production plant for water treatment chemicals in Nanjing, China, at the end of 2012. The BASF solutions Zetag® and Magnafloc® were specially designed for the solid/liquid separation process in industrial and municipal waste water treatment.
