Over the past decade, green chemistry has been emphasizing the importance of environmental sustainability and human health, aiming to minimize toxins and reducing wastes in an economically beneficial manner. The field of metallic materials deterioration, generally faced by the utilization of toxic compounds, discovered a promising research field in green chemistry. The application of inhibitors is a well-known strategy when metal corrosion needs to be avoided, prevented, controlled or mitigate. Green inhibitors are readily available, biodegradable, ecologically acceptable, sustainable and renewable sources. Their esteem broadens the numerous ranges of potential applications in various sectors besides “waste to energy” in the context of a circular economy. Extensive research on various biomass wastes such as corn stalks, nutshells, straw, forestry residue and plant waste-derived inhibitors tremendously has been utilized in corrosion mitigation in different industries to sustain the environment. All the mentioned aspects are the topic of this current review, which is meant as constructive criticism to spotlight the use of biomass waste as efficient green inhibitors in order to re-evaluate their viability and debate prospective research in the field, which is still lacking justification. As a result, this article aims to solve two current problems; waste and corrosion which will benefit both the environment and industry.
