Viridis Research Validates Textile Wastewater Recycling Technology in Dhaka Pilot with H&M Group
Viridis Research has successfully completed a full-scale pilot in Dhaka, Bangladesh, demonstrating that textile wastewater can be treated and reused. The project, in collaboration with H&M Group and textile mills, showed the company's electrochemical oxidation technology removed up to 99.94% of color from dye baths, allowing treated water to be reused in production. This breakthrough could significantly reduce freshwater usage in the textile industry.

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.
