Description :

This research focuses on the extraction, characterization, and application of chitin and
chitosan from marine waste sources. Chitin and chitosan, derived from abundant marine waste,
possess remarkable properties that make them highly desirable in various industries.
The importance of this research is twofold. Firstly, the lack of chitosan products in the Algerian
market presents a significant gap in the industry. By extracting chitosan from marine waste, this
research contributes to meeting market demands and opens avenues for economic growth and
product diversification. Secondly, the utilization of waste materials is a pressing concern
worldwide. Marine waste, if not properly managed, poses environmental hazards. By extracting
chitin and chitosan from these waste sources, this research tackles the waste management issue
while simultaneously producing valuable compounds with versatile applications.
The primary objective of this research is to develop and optimized an extraction approach for
chitin and chitosan. This approach aims to streamline the extraction process by reducing
processing time, minimizing reagent consumption, and optimizing yields. By achieving these
objectives, the research aims to promote sustainable waste utilization, meet market demands,
and demonstrate the broad potential of chitosan in various industries.
The research methodology involves implementing a chemical extraction process inspired by
multiple protocols. By combining and optimizing various extraction techniques, the study aims
to enhance the efficiency and effectiveness of chitin and chitosan extraction from marine waste
sources. The resulting chitosan will be meticulously tested and characterized to ensure its
quality, purity, and compatibility with different applications.
The research findings affirm our hypothesis that chitosan derived from marine waste can be
effectively extracted and utilized in various industries. This addresses the scarcity of chitosan
products in the Algerian market, opening up opportunities for economic growth and
technological advancement. The demonstrated antibacterial properties against bacteria and
fungi, wound healing capabilities, moisturizing effects, and bio stimulant potential of chitosan
validate its commercial viability and highlight its significance as a valuable resource derived
from waste materials.
In conclusion, this research contributes to bridging the gap in the Algerian market by
developing an efficient extraction method for chitin and chitosan from marine waste. The
utilization of waste materials through chitosan extraction not only addresses environmental
concerns but also provides new economic prospects. The diverse applications and commercial
viability of chitosan emphasize its potential as a valuable resource, supporting sustainable waste
management practices and promoting economic growth.
