This study evaluates the environmental impact of wastewater treatment in a textile dyeing plant through a Life Cycle Assessment (LCA) using a life cycle perspective though a “cradle to grave” life cycle assessment (LCA) following ISO 14040-44. Three treatment scenarios are compared: (1) the standard system currently in operation, (2) the integration of an electrochemical treatment to enhance efficiency and reduce pollutants, and (3) an optimized system that incorporates hydrogen recovery and reinjection as natural gas. The methodology follows ISO 14040 and 14044 guidelines, encompassing the collection of primary and secondary data on inputs, emissions, and waste generation for each scenario. Environmental impact categories such as carbon footprint, energy demand, and waste production are assessed. The results indicate that electrochemical treatment significantly reduces pollutant loads in the effluent, while hydrogen recovery further improves energy efficiency and decreases reliance on fossil fuels. Among the three scenarios, the third proves to be the most sustainable, demonstrating a substantial reduction in overall environmental impact. This study provides valuable insights for decision-making in the textile industry, supporting the adoption of more sustainable wastewater treatment solutions.
