Solid Waste Management of Fishery and Shrimp

Abstract

Solid waste management is one of the important areas focused by several researchers as it reduces environmental degradation, and offers useful or value added products. Fishery waste is significantly available in coastal areas and food processing industries which are a threat to the environment. Reuse or recycling is a better option to reduce the disposal of fishery waste. In this study, two different fishery wastes were investigated for their use for waste water treatment application. Chitosan was prepared from fishery and shrimp wastes by alkaline N-deacetylation process. Further Chitosan was characterised by the Fourier transform infra red analyser (FTIR), X-ray diffraction (XRD) and Viscosity-molecular weight. The FTIR results showed a more detailed structure of α-chitin in the region of O-H, N-H and CO stretching region. The FTIR spectrum was used to determine the chitosan degree of acetylation (DA).
