The global automotive industry is a major consumer of water. An estimated 148.000 liters of water is used to produce a single car. This covers the water used for processes like surface treatment and coating, painting, washing, cooling, air-conditioning systems and boilers. Metal finishing and especially painting accounts for the most significant water consumption, including the regular cleaning of the processing equipment.
In addition to the high water consumption, automotive production generates heavily polluted wastewater which requires extensive wastewater treatment in order to meet regulatory and environmental standards.
