DyStar And RedElec Start Sustainable Indigo Dyeing

Singapore — March 19, 2012 — DyStar and RedElec are pleased to announce a significant development
collaboration which focuses on sustainable Indigo dyeing for the denim industry.

technologies, throughout the development process.

environmental impact,” said Thorsten Hüls, Marketing Manager Denim in Ludwigshafen. “The
cooperation with RedElec is a big step forward to help improve the environmental profile of Indigo
dyeing,” added Günther Widler, Technology Manager Denim.
