Speciality coatings and treatments business Stahl has expanded its Zero Discharge of Hazardous Chemicals (ZDHC) MRSL 3.1 Gateway certification to 2,151 products, reports ILM.

The company noted that this achievement underlines its ongoing commitment to the ZDHC mission of achieving the highest standards for sustainable chemical management.

Level 3 is the highest level of conformity with the ZDHC certification programme. To achieve the certification, Stahl’s products were tested against the latest ZDHC Manufacturing Restricted Substances List (MRSL 3.1) by Eurofins | Chem-MAP alongside auditing of its facilities.
