In its Group Sustainability Strategy, it set out plans to reduce chemicals, partnering with ZDHC and Bluesign, and noted a specific focus on denim.

Ubaldo Minelli, CEO of OTB Group, said: “The OTB Group has been engaging for many years with the suppliers in its value chain around chemical management. We have been working especially on wet processes and with printing facilities to progressively phase out hazardous chemicals, by offering training and support to our suppliers in their journey towards more sustainable practices.

“By officially joining ZDHC, we want to raise our ambitions and partner with our fellow brands and other stakeholders across the globe to promote positive change around chemical management and water stewardship.” 

OTB owns Diesel, Maison Margiela, Marni, Viktor&Rolf, and Jil Sander. The group also controls and manages the Staff International and Brave Kid companies, and holds a minority investment in Amiri.
