Hazardous waste management is one of the problems our society is facing today. Expired drugs are a type of waste that is not reused in any way, but rather incinerated to be disposed of. These drugs have been proven to act as corrosion inhibitors for different metals and in different corrosive solutions. They are a good alternative to the synthetic inhibitors the industry uses today, due to their environmental friendliness, good corrosion inhibitor efficiency and economic advantages. The present research focuses on expired drugs as corrosion inhibitors for mild steel in concentrated sulfuric acid solution and characterize their inhibitive performance through weight loss measurements, Electrochemical Impedance Spectroscopy (EIS) spectra, and cyclic voltammetry (CV). The drug proved to be effective environmentally friendly corrosion inhibitor for mild steel, being a possible way of recycling expired drugs.
