Corrosion is an everyday challenge in all sectors of the economy particularly the manufacturing industry and this has led to massive economic loss. The aim of this research is to produce an eco-friendly inhibitor from cashew waste fruit. Cashew waste fruits collected were cleaned, washed, dried and pulverized. Mild carbon steel with thickness 0.1 cm was used and coupons of dimensions 4 x 5 x 0.1 cm. The cashew waste extract produced was used as a corrosion inhibitor on mild carbon steel in 0.1M hydrochloric acid. It was observed that as the concentration of inhibitor increases, the inhibitor efficiency also increases. The optimum inhibition efficiency observed in hydrochloric acid was 80.5%. After 336 hours of test, it was concluded that cashew waste is an efficient corrosion inhibitor as this will reduced the importation cost, increase the gross domestic product (GDP) of the nation and make the environment free of toxic chemical inhibitor. Keywords: Corrosion, Inhibitor, Mild Carbon steel, Cashew, Hydrochloric acid.
