Chitosan–Chitin Nanocrystal Films from Lobster and Spider Crab: Properties and Environmental Sustainability
The valorization of chitinous biomass from underutilized renewable carbon feedstock offers alternative routes for bioproduct development, reducing our dependence on nonrenewable and nonbiodegradable materials composed of fossil carbon. This work utilizes crustacean waste consisting of inedible shell...

The valorization of chitinous biomass from underutilized renewable carbon feedstock offers alternative routes for bioproduct development, reducing our dependence on nonrenewable and nonbiodegradable materials composed of fossil carbon. This work utilizes crustacean waste consisting of inedible shells to isolate chitin and its derivatives, chitin nanocrystals and chitosan, from lobster (Homarus gammarus) and spider crab (Maja squinado) shells. Chitin nanocrystals (ChNCs) with a degree of acetylation >93% and crystallinity >90% were obtained by demineralization, deproteinization and acid-hydrolysis, while chitosan was obtained by chitin deacetylation. Free-standing chitosan/ChNCs films were then fabricated from lobster and spider crab after dissolution and casting using 1.5% v/v formic acid.
