In 2011, the Zero Discharge of Hazardous Chemicals (ZDHC) Programme was formed to drive positive change in the discharge of hazardous chemicals across the product life cycle.
The ZDHC Programme aims to eliminate or substitute priority hazardous chemicals in products and their manufacture; apply a transparent screening process to promote and support safer chemistry; implement common tools, best practices and training that advance chemical stewardship; partner with stakeholders to promote chemical use and discharge transparency; promote scaling of best practices through engagement with key stakeholders.
A key component of the ZDHC Programme is the manufacturing restricted substance list (MRSL), a usage ban on specific chemicals. With this affiliation to the ZDHC Foundation, Stahl officially joins them in their commitment to eliminate these substances from the value chain by 2020.
