Exploring the Relationship Between Food Waste and Heavy Metal Extraction through Biosorption

Heavy metal elimination from polluted water is a prerequisite as they are hazardous to the environment as well as the health of people. Heavy metal removal from wastewater may be done effectively and economically via biosorption. Using waste materials as biosorbents from the food industry is an eco-friendly approach to waste management and pollution control. A considerable amount of waste is being generated from the food industry, such as grape pomace, coffee grounds, citrus peels, banana peels, coconut coir, tea waste, and rice husks, which are dominant in functional groups comparatively like carboxylic, hydroxyl, and amino groups that are proficient of binding heavy metals. A number of variables, consisting of temperature, pH, time of contact, and initial metal concentration, have an impact on the biosorption process. The routine technique for utilization of waste materials with respect to the food industry as biosorbents has several advantages, such as their abundance, budget-friendly, and ability to get rid of heavy metals effectively. In conclusion, waste materials from the food industry have the weightage to be utilized as effective biosorbents for heavy metals, providing a sustainable and eco-friendly solution for managing waste and pollution.
