One of the processes with enormous chemical consumption in_x000D_ industrial WWTP of textile facilities is the neutralization process, which aims to_x000D_ adjust the pH of the wastewater. Neutralization processes needed to be optimized_x000D_ in order to determine its overall environmental impacts and then identify the most_x000D_ environmentally appropriate options. The aim of this study is to compare the_x000D_ environmental impacts of carbon dioxide and sulfuric acid, which are two_x000D_ alternative chemicals used in the neutralization process of textile facilities, using_x000D_ Life Cycle Assessment (LCA) approach. The environmental impacts resulting from_x000D_ the use of these two chemicals proposed according to the Reference document on_x000D_ Best Available Techniques (BREF) Document for Textile Industry were revealed by_x000D_ the CML-IA method and the gate-to-gate method. According to the results, using_x000D_ carbon dioxide instead of sulfuric acid, the best improvement was in the abiotic_x000D_ depletion category with 92%, while the least improvement was in the_x000D_ eutrophication potential with 39%. No improvement was observed in the global_x000D_ warming potential and human toxicity impacts.enginfo:eu-repo/semantics/openAccessLife Cycle AssessmentNeutralizationSustainabilityTextile IndustryWastewater treatmentArticle
