Modern methods of seafood processing lead to the collection of a large amount of waste materials such as skin, head, tail, shell, scales, backbone, etc. In addition to the environment, improper waste management has negative consequences on human health. Seafood wastes often contain large amounts of bioactive peptides and bio compounds, which show characteristics such as biocompatibility, biodegradability, antimicrobial, antitumor, and antioxidant properties. This review is an attempt to convert marine waste into added value as a solution to waste management. From the data of some published articles from Science Direct, Pub Med, Scopus Springer Link, and Scopus databases, it was done using the keywords of aquatic waste, environmental protection, bioactive peptides, high-added value products, and biological products. The results showed that in Iran, aquatic wastes are used for the laboratory production of collagen, gelatin, sauce, fish meal, chondroitin sulfate, bone powder, chitin, organic fertilizer, chitosan, hydrolyzed protein, isinglass, silage, peptone, and the enzyme. Currently, aquatic wastes are used to produce fish powder, oil, and fish leather. The skin, and viscera are the parts that are most used in the preparation of value-added products. It is suggested that aquatic wastes be used to produce compounds such as compost, biogas, insulin, wound dressing, albumin, flavors, guanine crystals, squalene, methane, fish protein concentrate, pesticides, and fish compost in Iran.
Keywords: High value-added products, Bio-products, Global solutions, Seafood waste, Waste management.
