An experiment was conducted to determine whether expired XBAREN-150 could reduce the destruction of mild steel in 0.5 M sulphuric acid. Research aims to evaluate its inhibition efficiency, adsorption behavior, and environmental sustainability in industrial settings. Electrochemical analyses and weight loss tests, were utilized to find corrosion inhibition performance. Based on weight loss analysis, EIS results, and PDP results, XBAREN- 150 showed maximum inhibition efficiencies of 88.99%, 99.44%, and 97.10% at 400 ppm, respectively. According to adsorption studies, XBAREN-150 adheres to steel surfaces following the Langmuir isotherm model, affirming monolayer adsorption. The repurposing of expired XBAREN-150 to inhibit corrosion provides not only a sustainable option to conventional inhibitors, which are often toxic and environmentally hazardous, but it also reduces waste. Green chemistry and sustainable industrial practices are aligned with this eco-friendly approach because they reduce pharmaceutical waste and lower the impact of chemical inhibitor production.
