This research focuses on utilizing prawn shells to extract chitosan and produce bioplastic films. Methodologically, prawn shells undergo pre-treatment, demineralization, deproteination, and deacetylation processes, followed by material identification using fourier-transform infrared spectroscopy (FTIR) to calculate the degree of deacetylation. Chitosan-starch composite films are fabricated and characterized using FTIR, differential scanning calorimetry (DSC), field-emission scanning electron microscopy (FESEM), and energy dispersive X-ray spectroscopy (EDX) techniques. Soil biodegradation is assessed using ASTM D5988 standards. Chitosan-starch composite thin film was successfully synthesized from the extracted chitosan with a 76.16% deacetylation rate. The films exhibit varying thermal properties influenced by glycerol content, with higher glycerol levels accelerating soil biodegradation. This study highlights the potential of utilizing prawn shell waste for sustainable bioplastic production, contributing to waste reduction and environmental sustainability initiatives.

摘要

This research focuses on utilizing prawn shells to extract chitosan and produce bioplastic films. Methodologically, prawn shells undergo pre-treatment, demineralization, deproteination, and deacetylation processes, followed by material identification using fourier-transform infrared spectroscopy (FTIR) to calculate the degree of deacetylation. Chitosan-starch composite films are fabricated and characterized using FTIR, differential scanning calorimetry (DSC), field-emission scanning electron microscopy (FESEM), and energy dispersive X-ray spectroscopy (EDX) techniques. Soil biodegradation is assessed using ASTM D5988 standards. Chitosan-starch composite thin film was successfully synthesized from the extracted chitosan with a 76.16% deacetylation rate. The films exhibit varying thermal properties influenced by glycerol content, with higher glycerol levels accelerating soil biodegradation. This study highlights the potential of utilizing prawn shell waste for sustainable bioplastic production, contributing to waste reduction and environmental sustainability initiatives.
