In the present study, fish scales waste was processed to produce chitin and chitosan. Chemical extraction was followed for chitin and chitosan production. In this method, deproteination and demineralization was done by using NaOH and HCl, respectively. After these two steps formed compound was chitin which was further processed to form chitosan following deacetylation step. Compositional analysis of fish scale waste was done by standard methods which reveal that protein content was high. Mineral composition analyzed by Inductively Coupled Plasma Optical Emission (ICP-OES) confirms the presence of high amount of macro minerals (%) and micro minerals (ppm) such as calcium, phosphorous and copper, iron i.e. 13.9±0.21, 5.77±0.05 and 129.30±8.05, 83.39±15.48, respectively. Chitin and chitosan yield (%) from fish scale waste was found to be 1.1 ± 0.004 and 0.85 ± 0.01 which shows that fish scale waste is a good source of chitin and chitosan.
