The wastewater treatment in the textile industry is of special importance due to the
intensive use of chemicals and dyes. However, wastewater treatment plants have impacts on
environmental and these environmental impacts should also be evaluated and minimized.
Neutralization is one of the processes with the huge chemical consumption in the wastewater
treatment plant. Therefore, the chemical alternatives used in the neutralization process should
be compared in terms of their environmental impacts. In this study, the performances of carbon
dioxide and sulfuric acid as two alternative chemicals used in the neutralization process applied
in a textile factory wastewater treatment plant are compared using the life cycle approach. The
neutralization process using carbon dioxide yielded better results in the categories of abiotic
depletion, fossil fuels, ozone layer depletion (ODP), fresh aquatic ecotoxicity, marine aquatic
ecotoxicity, terrestrial ecotoxicity, photochemical oxidation, acidification, and eutrophication.
