Zero Discharge of Hazardous Chemicals (ZDHC)
The Zero Discharge of Hazardous Chemicals (ZDHC) multi-stakeholder collaboration initiated a special focus and task teams for wastewater, sludge, solid waste and air emissions in the textile industry. Lenzing has been part of the Man-Made Cellulosic Fibers (MMCF) task team on wastewater, sludge, solid waste and air emissions since 2018. In 2020, Lenzing adopted the published ZDHC guidelines on wastewater, air emissions and responsible fiber production for MMCF manufacturers. In 2021, Lenzing started the ZDHC Gateway reporting in accordance with the wastewater guideline in its viscose operations in Purwakarta (Indonesia), Nanjing (China) and Lenzing (Austria). In 2023 the revised and extended MMCF guideline which includes other fibers such as lyocell was published. Lenzing is implementing that guideline and the first reporting for the lyocell sites started in October 2023.
