Arvind unveils India’s first supercritical CO2 dyeing machine

Arvind, one of India’s leading textile-to-retail companies, has launched the country’s first supercritical CO2 dyeing machine. The machine, developed in partnership with global fashion giant H&M Group and Mumbai-based start-up Deven Supercriticals, has been set up at Arvind’s Ahmedabad facility.

Patented worldwide under the brand name Suprauno, the technology replaces water with supercritical carbon dioxide in the dyeing process. On an industrial scale, it can save up to 76% water, cut energy use by about 67%, reduce chemical consumption by 90% during coloration, and significantly lower effluent discharge compared to traditional dyeing methods.

This milestone is the result of a unique three-way collaboration. Deven Supercriticals introduced the breakthrough technology, Arvind enabled its large-scale deployment, and H&M Group supported the adoption to meet its sustainability goals. It marks the first effort to successfully move such an innovation from laboratory trials to bulk production.

“This inauguration represents a defining moment for the Indian textile industry,” said Punit Lalbhai, Vice Chairman of Arvind. “Our partnership shows that innovation, scalability, and sustainability can progress together.”

Omang Narang, Production Manager for H&M Group in India, added, “We see electrification as key to making textiles fossil-free. Since wet processing is the most resource-intensive stage in fashion’s value chain, water- and energy-efficient solutions like this make electrification more practical.”
