H&M backs India’s first supercritical CO2 dyeing machine
India-based mill Arvind Limited, in collaboration with H&M Group and Indian start-up Deven Supercriticals, has inaugurated India’s first supercritical CO2 dyeing machine at its facility in Ahmedabad.
This technology, patented under the Suprauno brand, reduces 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 with conventional dyeing methods, said the partners.
Punit Lalbhai, vice-chairman of Arvind, said: “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.”
Omang Narang, H&M Group’s production manager for India, added: “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."
India’s Ministry of Textiles has also supported the initiative.
