Viridis Research, based in Vancouver, completed a full-scale industrial pilot in Dhaka, Bangladesh, with H&M Group and three textile mills, proving that textile wastewater can be treated and reused. The electrochemical oxidation technology achieved removal rates of 99.56% to 99.94% of color from dye baths.

Treated water met quality standards for reuse in dye cycles, and valuable chemicals were recovered, demonstrating that the system eliminates pollutants rather than transferring them. The technology has the potential to reduce freshwater intake and effluent discharge across textile manufacturing. Viridis is now pursuing broader deployment within textile supply chains.
