The need for developing renewable materials to reduce the reliance on fossil fuels as a feedstock for a wide variety of uses is becoming increasingly widely acknowledged in society. Chitin, the second most abundant nitrogenous natural polymer derived from renewable biomass resources, have attracted significant interest as a promising natural source to produce functional materials due to their unique properties, abundant availability, and environmental appeal. Chitin is present in huge amounts in seafood waste, which is severely underutilized, resulting in resource wastage. An appealing alternative is to upcycle chitin-containing trash into value-added goods, to meet the sustainable development requirements. Since the large quantities of seafood waste remain underexploited, their utilization can potentially bring both ecological and economic benefits. The present review discusses the general properties of chitin and chitosan as natural polysaccharides, highlighting the innovative and eco-friendly methods for recovery of chitin and its derivatives from waste sources. The recent trends of the application of chitin and chitosan in various sectors are explored, highlighting the nexus between the generation and management of seafood waste and its transformation into valuable commercial products as a solution.
