The Zero Discharge of Hazardous Chemicals (ZDHC), an international environmental group for the textile industry, includes major brands such as Nike, Puma, M&S, and Burberry. Its mission is to achieve zero emissions of hazardous chemicals from the textile supply chain by 2020. ZDHC recently updated its Manufacturing Restricted Substance List (MRSL) to include leather in its hazardous substance control scope. This updated MRSL 1.1 will provide a more consistent direction for chemical substance management across the textile industry. According to ZDHC, MRSL 1.1 not only regulates textile and footwear manufacturers but also includes chemical manufacturers and manufacturers of decorative parts for clothing and shoes. Restricted chemicals include solvents, detergents, adhesives, coatings, inks, detergents, dyes, colorants, auxiliaries, surface coatings, and setting agents that may be used in raw material processing, wet processing, repair, wastewater treatment, sanitation, and pest control. Frank Michel, Executive Director of ZDHC, stated that MRSL 1.1 provides a consistent chemical substance specification guideline, assisting brands in effectively communicating with their supply chains and reaching agreements on chemical substances.
