The CO2 dyeing machine is based at Arvind's facility in Ahmedabad, India, it is supported by H&M Group and features Deven Supercriticals' innovation to enable scaling of innovation from lab to bulk scale.
The technology is globally patented under the SUPRAUNO brand and aims to reduce the use of water in the fabric dyeing process by using supercritical carbon dioxide.
At a commercial scale, it delivers up to 76% water savings, 67% energy savings, and 90% reduction in chemical usage within the coloration stage compared to conventional dyeing methods, while also significantly reducing effluent discharge.
H&M Group’s production manager for India Omang Narang said: “We recognise that electrification is essential for making the textile industry fossil-free. Wet processing is the single most impactful area in the value chain for fashion brands like ours, and water- and energy-efficient technologies like this one make further electrification more feasible. We are proud that our support helps drive the entire industry forward."
Arvind Ltd vice chairman Punit Lalbhai added: “This inauguration represents a defining moment for the Indian textile industry. By hosting the world’s first commercial-scale SUPRAUNO machine at Arvind, we reaffirm our commitment to pioneering sustainable solutions and setting global benchmarks. This collaboration is proof that innovation, scale, and sustainability can go hand in hand.”
Deven Supercriticals Pvt. Ltd founder Dr. Swapneshu Baser agreed, stating: “We are immensely proud to see our patented SUPRAUNO technology being inaugurated at commercial scale in India. This machine is not just a technological milestone but also a step towards safeguarding water, energy, and health for future generations. We are grateful to H&M Group and Arvind for their faith in this innovation and for making this vision a reality.”
Arvind points out the Government of India’s Ministry of Textiles has also shown its support for the initiative as it sits within its wider vision of building a sustainable, circular, and globally competitive textile sector. Plus, it places Indian innovation at the forefront of a global textile transformation.
