ARCHROMA, G-STAR RAW AND ADVANCE DENIM PROMOTE CLEANER DENIM
PRODUCTION

Pratteln, Switzerland, 3 April 2024 - With the aim to help the denim industry reduce theenvironmental impact of its wastewater and move towards circularity, three leaders fromacross the denim supply chain have renewed their joint commitment to the production ofaniline-free denim apparel based on Archroma’s DENISOL ® PURE INDIGO 30.
Archroma, a global leader in specialty chemicals towards sustainable solutions, has beenworking with innovative Dutch denim brand G-Star RAW and sustainable denim leader
Advance Denim since 2019.
Their joint aim is to produce high-quality denim in authentic blue shades without the aniline
impurity carried through from the synthesis of standard synthetic indigo. In traditional
denim production, this aniline remains bound with the indigo pigment on t he fabric; theremaining aniline is discharged during the dyeing and washing process. This can be aproblem because aniline is toxic to aquatic life and two-thirds of aniline waste currently
ends up in wastewater discharge where it could potentially pollut e waterways and theocean.
Archroma developed DENISOL ® PURE INDIGO 30 to answer this key challenge. A 30%
pre-reduced indigo solution, DENISOL ® PURE INDIGO 30 makes it possible to produce
indigo-dyed denim without aniline impurities throughout the process.
Easy to use with automated dosing, DENISOL ® PURE INDIGO 30 significantly reduces thewater needed for preparation, washing and wastewater treatment compared to indigograins. It also reduces hazardous chemical consumption while allowing high reproducibility
and creating the authentic and iconic deep indigo shades traditionally associated withdenim.
“If we remove aniline from the indigo dyes, we also remove it from the denim production
process and its wastewater, and thus eliminate the risk of pollution. Denim that is free ofaniline can also be more efficiently and sustainability recycled and reused, making
circularity a more viable option,” Umberto De Vita, Market Segment Director for Denim,
Archroma Textile Effects, said. “We are delighted to see trendsetters like G -Star RAW
ramping up aniline-free production with DENISOL ® PURE INDIGO 30, proving thatsustainability is achievable with improved productivity and authentic deep indigo shades.”“To be here as the denim brand in the future, G-Star RAW challenges industry standards,”
Rebecka Sancho, G-Star RAW said. “We push boundaries in our journey to further close
the loop by using sustainable materials, clean chemistry and by designing for dura bilityand reuse. DENISOL ® PURE INDIGO 30 helps us to minimize pollution and improve theenvironmental impact of our products without compromising on iconic indigo colors.”

G-Star RAW is working towards making 20% of its entire collection from Cradle to Cradle
Certified ® fabrics by 2025. Its partnership with Archroma and Advance Denim contributes
to this goal, since the aniline-free DENISOL ® holds a Gold Level Material Health Certificate
from the Cradle to Cradle Products Innovation Institute. DENISOL ® PURE INDIGO 30 isalso compliant with other major eco-standards and the requirements of leading retailers
and brands.
“As a company that is dedicated to the production of denim that is both authentic andsustainable, Advance Denim is proud to work with industry innovators like Archroma andG-Star RAW,” Amy Wang, Managing Director, Advance Denim, said. “We were the first m illin China to launch an aniline-free collection with Archroma and our new plant in the resort
town of Nha Trang in Vietnam is a 100% aniline-free indigo factory with DENISOL ® PURE
INDIGO 30 by Archroma.”
Johan Van den Heede, Director – Europe Marketing, Advance Denim, added, “We arehonored to stand alongside Archroma and G-Star RAW to pioneer cleaner denim
production methods that reflect our unwavering commitment to sustainability andinnovation.”
