Challenging conventions in the denim industry
Optimizing Water Consumption and GHG Emissions
Denim production is notoriously water-intensive and responsible for wastewater pollution in global production locations that are already under water stress. It also generates substantial GHG emissions throughout the supply chain, from carbon-intensive materials to manufacturing, coloration and washing, and consumer use and disposal.
We recently expanded our DIRESUL® RDT range to include DIRESUL® EVOLUTION BLACK LIQ. Based on cutting-edge synthesis technology developed by Archroma, it delivers an overall impact reduction to 57% compared to standard Sulfur Black 1 liquid.

Enhancing Chemical Management
Denim brands are placing greater emphasis on eliminating hazardous chemicals and reduce pollution, further elevating the significance of effective chemical management.
Archroma disrupted the denim industry in 2018 with the introduction of an aniline-free* indigo alternative: DENISOL® PURE INDIGO. With the world’s major clothing brands and retailers increasingly looking to eliminate aniline from their supply chains, many leading mills are now switching to aniline-free DENISOL® PURE.
Embracing Circularity
The denim industry's heavy reliance on fossil fuels, legacy production processes, and global supply chain complexity continue to hamper efforts to move towards greater circularity.
Introduced in 2017, EarthColors® is a range of biosynthetic dyes synthesized from natural waste products from the agriculture and herbal industries; leaving the edible part still available for food consumption. Compared to conventional synthetic dyes, which use petroleum-based raw materials, this technology helps to reduce water footprint and climate impact and protect our natural resources.*[*Below limits of detection according to industry standard test methods ** Based on internal LCA comparative screening]* Upcycling natural waste in this way also has no negative impact on any other steps of dye manufacturing, such as water and energy consumption or waste generation. EarthColors® is transformed into a new dyestuff using up to 100% of raw materials from natural waste, helping us close the loop.
Launched in 2023, FiberColors® is an innovative range of dyes based on a revolutionary technology that turns pre- and post-consumer textile waste into its own beautiful colors. It is synthesized with a minimum of 50% textile-waste raw material. FiberColors® uses cotton, polyamide, and their blends (with more than 95% purity) to substitute a major part of the petroleum-based raw material that is usually used to make dyestuff . This approach allows for either virgin and/or recycled waste to be used, keeping waste from landfills.
The waste raw materials can be any color and does not need to be sorted by color. The FiberColors® range comprises of five dyes, covering a palette of brown, olive, bordeaux, blue and grey shades. It enables the creation of diverse collections, from t-shirts and chinos, to sweatshirts, hoodies, polo shirts, and home textiles—supporting the circular economy.
Throughout this journey, we have remained committed to innovation, sustainability, and resource efficiency. Archroma has advanced our solutions as well as redefined the industry's approach to more sustainable coloration in the denim industry. We remain dedicated to pushing the boundaries of what's possible, striving for a textile industry that is eco-conscious and yet can also fulfill consumer trends of today and tomorrow.

What Goes Into The Box - Chemistry's Fundamental Role in Sustainable Packaging
Without chemistry we wouldn’t have packaging at all — sustainable or otherwise. Yet, the role of chemistry in packaging is often unacknowledged, even by seasoned packaging professionals. This article explores the role of chemistry, both as an integral part of every package, and as the driving force behind true circularity in this sector.
From Pulp to Package, Package to Pulp (and back again)
The paperization trend in modern packaging has many drivers: regulatory developments, growing environmental awareness, changing consumer sentiment — all these, and more, contribute to its increasing relevance. Fully realizing its potential involves overcoming multiple practical challenges, and packaging producers need partners who understand what happens at every step of the value chain loop.
