Water in the BASF Group in 2013
(million cubic meters per year)
1 Total from production processes, graywater, rinsing and purification in production
2 The difference between the volume of water supplied and discharged is mainly attributable to evaporation losses during closed-circuit cooling.
We recirculate water as much as possible in order to withdraw less from supply sources. We have recooling plants at our larger sites to reduce the temperature of the cooling water before it is discharged back into a body of water. To protect the Rhine River, we have committed to the step-by-step reduction of heat input from the Ludwigshafen site when set temperature limits are exceeded, for example as a result of long heat waves or low river levels.
The supply, treatment, transportation and recooling of water is associated with a high energy demand. By applying diverse measures, we aim to keep this as low as possible.
