ZDHC Releases Key Joint Roadmap Milestone: Updated MRSL Now Includes Leather

Today, the Zero Discharge of Hazardous Chemicals Programme released an update to the Manufacturing Restricted Substances List to now include leather.

The MRSL Version 1.1 was developed by the ZDHC apparel and footwear brands in close collaboration with third-party technical experts and global industry associations.

“The ZDHC MRSL Version 1.1 provides brands and suppliers with a harmonised approach to managing chemicals during raw material processing,” said ZDHC Executive Director Frank Michel.

“Collaborating with leading technical experts allowed us to develop this synchronised approach and advance our long-term goal of zero discharge. ZDHC brands will be communicating MRSL Version 1.1 information to their raw material supply chain and factories assembling or manufacturing garments and footwear, and expect them to communicate directly with their chemical suppliers so that the listed substances are not present in chemical formulations above established MRSL limits."

The ZDHC MRSL Version 1.1 includes chemicals used in facilities that process materials and trim parts for use in apparel and footwear. These chemicals include solvents, cleaners, adhesives, paints, inks, detergents, dyes, colourants, auxiliaries, coatings and finishing agents used during raw material production, wet-processing, maintenance, wastewater treatment, sanitation and pest control.

The MRSL Version 1.1 establishes concentration limits for these substances that are designed to eliminate the possibility of intentional use of listed substances. The list will assist brands, organisations throughout supply chains and the broader industry in phasing out/substituting hazardous substances potentially used and discharged into the environment during manufacturing and related processes.

To support raw material suppliers, including wet-processing facilities, subcontractors and factories assembling or manufacturing garments and footwear transitioning to this new chemical guidance, the ZDHC Programme is accompanying the release of the MRSL Version 1.1 with supplier guidance, support materials and training.
