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 fossil carbon. This work utilizes crustacean waste consisting inedible shells to isolate chitin its derivatives, nanocrystals chitosan, lobster (Homarus gammarus) spider crab (Maja squinado) shells. Chitin (ChNCs) with a degree acetylation >93% crystallinity >90% were obtained by demineralization, deproteinization acid-hydrolysis, while chitosan was deacetylation. Free-standing chitosan/ChNCs films then fabricated after dissolution casting using 1.5% v/v formic acid. Lobster-derived exhibited good balance between UV-shielding ability, blocking >96% UV-C UV-B, being transparent at visible wavelengths. Neat are semiductile, elongations break >13% Young's modulus values 2.3 ± 0.7 3.4 1.2 GPa crab-derived respectively. Besides, the incorporation ChNCs increases 5.5 0.8 2 wt % lobster-derived films. Life cycle assessment (LCA) conducted quantify environmental impact film production identify process hotspots future optimization. A footprint 79.8 kg CO2 equiv·kg–1 is chitosan/ChNC processed 100% energy mix. Results demonstrate that relevant contenders toward defossilization developing renewable-carbon containing bioproducts competitive performance against fossil-based due their optical mechanical properties, as well potential biodegradability.
