Water is used at the production facilities of the Lenzing Group primarily as process water for pulp and fiber production and for cooling the equipment. Unlike wastewater from production, cooling water is subject to no emissions but only to thermal energy (i.e. it is heated up).
The above diagram presents the volume of wastewater and process cooling water at the individual sites per m³/ton of fiber or dissolving wood pulp manufactured. The water consumed by ancillary equipment, such as an on-site power plant, is included in the calculation.
