According to the abstract released by the Intellectual Property India: "Sea waste management has been a global problem, as it causes environmental pollution when discarded or landfilled. To tackle this global issue, we develop an alternative bio-waste-mediated preparation of 'Chitosan' using sea waste, such as Shrimp shell waste, herein. In addition, chemically synthesised chitosan is inexpensive and widely available, but it suffers from reproducibility, contamination, and environmental problems that limit its use in high-value, regulated applications. Biosynthesised chitosan promises better control, cleaner supply, and greener processing, making it increasingly attractive for biomedical, food, and premium uses. In the present investigation, shrimp shells were systematically processed, which included washing, cleaning, crushing, demineralisation, deproteinization, deacetylation, and thermal treatment. The prepared Chitosan was studied through XRD, SEM-EDS, and FTIR spectroscopic techniques to investigate its structural, microstructural, and compositional properties. The results reveal that the synthesised chitosan demonstrated a degree of deacetylation (DD) of 65-67%, which is slightly lower compared to commercial chitosan (approximately 70-72%). This indicates that the synthesised chitosan has moderate deacetylation and reactivity compared to the higher solubility and amino-group availability of the commercial sample. Despite this difference, the synthesised chitosan offers the significant advantage of controlled laboratory production, allowing tailored structural and functional modifications that are not always achievable with commercial materials. Additionally, this method also generates useful materials from sea waste, providing a global waste-management solution. The results indicate that the bio-derived chitosan holds strong potential for future applications in areas such as drug delivery, nanoparticle stabilisation, wound-healing systems, and water-treatment technologies."
