Management of water discharge-related impacts

Since 2010, we have pursued the goal of continuously reducing the chemical oxygen demand (COD) in our wastewater. By 2025, we would like to increase in the efficiency of the chemical oxygen demand in wastewater by 4 % annually or by a total of 60 % compared to the base year 2010.

Every site around the world follows the local limits of their respective country and measures COD around the clock, every day of the week. At our site in Holzminden, the authorities also administer unannounced spot tests, supplementing our measurements, so that there is never any violation of the German Direct Discharge Regulation. Tests are also conducted by authorities in other countries. We are not aware of any significant violations.
