“…The weight loss balance technique is often deployed to test the organic green corrosion inhibitor efficiency, as supported by Haldhar et al [57], who highlighted that this method is chosen because of its reliability and straightforwardness. Various past studies used this method for Xanthium strumarium leaves [44], tomato peel [92], and Chlorella sorokiniana [111]. According to Khadom et al [44], the corrosion rate can be calculated from Equation (13).…”

Acid corrosion is a problem pertaining to corrosion that involves an acid solution. It is important to treat metal to preserve its integrity. Thus, acids are utilized to clean and treat metal surfaces. In return, this may lead to over-etching and metal degradation. Corrosion inhibitors were introduced as a solution for the issue. However, there are some problems associated with the usage of conventional corrosion inhibitors. Traces of nitrites and chromates that are present in the inhibitors may lead to serious health and environmental issues. As a solution, organic green corrosion inhibitors have been studied to replace the conventional corrosion inhibitors. These inhibitor molecules form a protective layer on top of the metal surface to suppress metal dissolution when added to the acid solution. This process prevents direct contact between the metal surfaces and the acid environment. This study explores the usage of natural resources and biomass wastes as the basis for organic green corrosion inhibitors. This study also provides some suggestions for new biomass wastes that can be studied as new organic corrosion inhibitors, and it is aimed at opening the perspective of researchers on exploring new organic inhibitors by using natural resources and biomass wastes.

“…Pectins are traditionally obtained from agricultural by-products, such as citrus peels and apple pomace [ 33 , 34 ]. The increasing global demand for this heteropolysaccharide due to the numerous health benefits attributed to it [ 35 ] means that alternative sources of pectin are being sought in other vegetables and by-products, such as eggplant [ 36 ], tomato peel [ 37 , 38 ], broccoli stem [ 39 ] and pomegranate peel [ 40 ], among others.…”

Nowadays, there is a growing interest in the extraction and identification of new high added-value compounds from the agro-food industry that will valorize the great amount of by-products generated. Many of these bioactive compounds have shown beneficial effects for humans in terms of disease prevention, but they are also of great interest in the food industry due to their effect of extending the shelf life of foods by their well-known antioxidant and antimicrobial activity. For this reason, an additional research objective is to establish the best conditions for obtaining these compounds from complex by-product structures without altering their activity or even increasing it. This review highlights recent work on the identification and characterization of bioactive compounds from vegetable by-products, their functional activity, new methodologies for the extraction of bioactive compounds from vegetables, possibly increasing their biological activity, and the future of the global functional food and nutraceuticals market.

“…[5] As such, there has been increasing research into further identifying naturally occurring inhibitors, which may better address the problem of metal corrosion in aqueous media. For example, Zhang et al [6] evaluated Idesia fruit extracts as a corrosion inhibitor for copper in a 0.5M sulfuric acid solution; Halambek et al [7] used pectins from tomato peel waste as a corrosion inhibitor for tin in a sodium chloride/ acetic acid solution; Wang et al [8] evaluated the extract of tobacco rob as a scale and corrosion inhibitor in artificial seawater; Vera et al [9] used apple peel waste as a steel corrosion inhibitor in a saline solution, among other authors. [6][7][8][9][10][11][12][13] For this reason, this study obtained an organic inhibitor from natural extracts from the fruit of Geoffroea decorticans, a desert plant endemic to northern Chile commonly known as Chañar, and evaluated its effects against corrosion of carbon steel under a saline environment.…”

The use of inhibitors is one of the most practical modern methods in preventing and protecting against metal and alloy pipe corrosion. Exploring such additional inhibitors, particularly of natural origins, has become a key area of research. The present work, thus, evaluates the extract of a desert plant fruit, endemic to northern Chile, called Chañar (Geoffroea decorticans), as an inhibitor for the corrosion of A36 steel under a saline environment. Extract inhibition efficiency was evaluated by mass loss, polarization curves, and electrochemical impedance spectroscopy, and surface morphology of the steel after assays was analyzed by scanning electron microscopy. Results showed the formation of a smooth surface on the steel in the presence of the extract and a rough surface in the absence of the extract; also, polarization curves indicated an inhibition efficiency of approximately 82% at a concentration of 200ppm extract, corroborated by electrochemical impedance spectroscopy. The adsorption of the extract on the steel surface follows Langmuir's isotherm model, for which thermodynamic parameters suggest a physisorption mechanism.
