Withdrawal, use and discharge of water
Essity’s reporting of water withdrawal states totals for surface water, groundwater and municipal water systems. Surface water, which represents the largest share of water withdrawal, as a general rule must be purified from dissolved and solid content before use in the production process. Most of Essity’s water is used to transport fibers during production processes. The remainder is mainly used as cooling water.
Essity’s water discharge is divided into cooling water and process water. Cooling water has simply been heated and is not contaminated in any way. Process water is treated using mechanical and biological treatment systems before it is discharged.
In 2021, six of Essity’s wholly owned paper mills were located in water-stressed areas with the risk of a water shortage. The sites accounted for 7% of Essity’s total water withdrawal, distributed between 32% from surface sources, 44% from groundwater and the remainder from recycled water or from municipal water systems. Total water withdrawal from these facilities in 2021 was 6.7 million m3, water discharges 4.5 million m3 and water consumption 2.2 million m3.
Any environmental incidents are registered in a central incident-reporting system. In 2021, no incidents relating to temporary exceedances of permitted limit values for waste water were registered. No incident was of such a magnitude that it posed a threat to an emissions permit.
