The ZDHC Roadmap to Zero Programme has published the document for ZDHC Wastewater Treatment Technologies that can be used as a guidance to improve the quality of wastewater discharge in the apparel, textileand footwear industry. The first guidelines were released in 2016. These rules set unified expectations on the quality of wastewater. The apparel, textile and footwear industry uses huge amounts of water in production processes, after which the water is often discharged in a way that harms the environment and surrounding communities. Especially in China, South and Southeast Asia and other production countries around the world, this has become a huge problem over the last few years.
