The watermelon rind extract molecules are used in the inhibition of API 5L steel in 0.5 M H2SO4 solution. Watermelon is an agro waste which is being discarded after the fleshy part has been consumed which causes environmental pollution. The rind is one of the possible ways for green chemistry and sustainable of protecting API 5L steel used in petrochemical environments from corrosion. The corrosion test utilized in this research is weight loss and polarization techniques. The results showed that watermelon rind is an effective inhibitor in 0.5 M H2SO4. The results showed an optimum inhibition efficiency of 99.9% at 4% of the inhibitor concentration which is still retained at 5% for the polarization test. The weight loss experiment shows the highest inhibition efficiency of 84% at 3% of the inhibitor concentration. The inhibition efficiency could be attributed to the presence of organic compounds and functional groups present in the extract which was shown with the aid of the elemental analysis, phytochemical analysis and the Fourier Transform Infrared Spectrum.
