ZDHC publishes Leather Wastewater Guidelines Addendum

The ZDHC Leather Wastewater Guidelines Addendum were created to expand the scope to include the leather industry, and are an addition to the current ZDHC Wastewater Guidelines Version 1.1. These ZDHC Leather Wastewater Guidelines set a single unified expectation for sampling, testing and reporting of industrial wastewater and sludge resulting from leather processing.  They were developed in collaboration with a wide range of stakeholders from the leather industry including manufacturers, brands, chemical suppliers and laboratories.
