The textile industry is known to be an intensive sector, specifically it requires massive quantities of energy, natural gas, and water to produce fabric, the used water ends up being polluted, containing high concentrations of dye, and then is poured into the sewage system. The environmental impact of this industry sector is significant large. This study analyses textile industry data and evaluates the feasibility and potential benefits of integrating an electrochemical system capable of removing pollutants, obtaining hydrogen to be used as a blended fuel, reducing natural gas consumption, and creating a circular economic process with the reintroduction of the treated water back to the system. An Anion exchange membrane electrolyzer is used to remove pollutants and recover hydrogen, the system achieves a dye removal of 99% with and energy increase of 3%, the system produces 1,12 kg of Hydrogen per treated batch of used water, yearly hydrogen production represents a reduction of 2% on natural gas consumption and an overall avoidance of carbon dioxide of 1.3%. An overall economic impact of 3,5% when it comes to resource consumption. The integration of electrochemical technologies proves a feasible and sustainable approach for treating textile wastewater while recovering hydrogen for use as a blended fuel, reducing environmental impact, and promoting a circular economy, while having a small economic increase in resources. These findings highlight the potential dual benefits of water electrolysis to mitigate the environmental impact of textile production while generating a valuable, sustainable energy source. |
