Abstract
The present review is intended to report a series of works aimed to alleviate of the environmental pollution by converting plastic waste into useful products, and to evaluate the inhibition action of plastic waste on the corrosion of steel alloys, in different aqueous media. poly(ethylene terephthalate), PET plastic waste was used as cheap and safe corrosion inhibitors for steel in hydrochloric acid, sulfuric acid, acetic acid, formic acid, nitric acid corrosive media, and in aqueous saline corrosive medium. The present part reports the evaluation of PET waste and their modified products as corrosion inhibitors for steel in different media by chemical and electrochemical measurements. The review summarizes all scientific efforts and highlight the new method introduced by R. Abdel Hameed which is a novel idea involved the green recycling of plastic waste via a solvent free green method and using the modified product obtained as green corrosion inhibitors.
