From Fish Processing Waste to Value-Added Products: Innovation for a Sustainable and Circular Blue Economy

Fish processing generates enormous quantities of by and shells—that are frequently discarded despite holding substantial biological and economic value. As global seafood consumption rises, so does the volume o burden and a missed opportunity for resource recovery. Emerging technologies now allow these residues to be transformed into valuable products such as fish protein hydrolysates, collagen and gelatin, chitosan, fish oil rich in omega valorization not only reduces pollution and disposal costs but also opens new revenue streams for fishery-based industries, aligning with the principles of a circular diverse pathways for converting fish processing waste into commercially viable and nutritionally beneficial products, highlighting recent innovations in extra Fish processing generates enormous quantities of by-products—heads, skins, bones, viscera, scales, that are frequently discarded despite holding substantial biological and economic value. As global seafood consumption rises, so does the volume of this waste, creating both an environmental burden and a missed opportunity for resource recovery. Emerging technologies now allow these residues to be transformed into valuable products such as fish protein hydrolysates, collagen and ish oil rich in omega-3 fatty acids, bioactive peptides, fertilizers, and biofuels. Such valorization not only reduces pollution and disposal costs but also opens new revenue streams for based industries, aligning with the principles of a circular economy. This article explores the diverse pathways for converting fish processing waste into commercially viable and nutritionally beneficial products, highlighting recent innovations in extraction and processing techniques burden and a missed opportunity for resource recovery. Emerging technologies now allow these residues to be transformed into valuable products such as fish protein hydrolysates, collagen and 3 fatty acids, bioactive peptides, fertilizers, and biofuels. Such valorization not only reduces pollution and disposal costs but also opens new revenue streams for economy. This article explores the diverse pathways for converting fish processing waste into commercially viable and nutritionally ction and processing techniques.
