The Ahmedabad-based Arvind Envisol, a 100 per cent subsidiary of textile major, Arvind Ltd. is a water recycling solution and technology provider. The inspiration to set up the subsidiary came after Arvind set up its Santej plant in Gujarat way back in 1997 in which the company had installed a one-of-its-kind zero liquid discharge (ZLD) plant for effluent treatment of 10 MLD capacity which was then the largest in Asia.
