“…Optimization techniques generally used in processing biological raw materials are based on adequate experimental programs, and subsequent statistical analysis and modelling in the frame of Response Surface Methodology (RSM) or using neural networks [ 17 ]. For instance, Iber et al [ 18 ] used the Box–Behnken experimental program for the optimization of chitosan coagulant from dry legs of giant freshwater prawn, while Younes et al [ 19 ] optimized the chitosan preparation from shrimps starting from experimental data for enzymatic deproteinization obtained in the frame of the Box–Behnken program. In the study of Bajić et al [ 20 ], the link between the composition of the film-forming solution and the properties of the chitosan for food packing design is carried out using RSM modelling and Box–Behnken experimental design.…”

Shrimp waste is a valuable source for chitin extraction and consequently for chitosan preparation. In the process of obtaining chitosan, a determining step is the chitin deacetylation. The main characteristic of chitosan is the degree of deacetylation, which must be as high as possible. The molar mass is another important parameter that defines its utilizations, and according to these, high or low molar masses are required. The present study is an attempt to optimize the deacetylation step to obtain chitosan with a high degree of deacetylation and high or low molar mass. The study was carried out based on experimental data obtained in the frame of a central composite design where three working parameters were considered: NaOH concentration, liquid:solid ratio, and process duration. The regression models defined for the degree of deacetylation (DD) and for the mean molar mass (MM) of chitosan powders were used in the formulation of optimization problems. The objectives considered were simultaneous maximum DD and maximum/minimum MM for the final chitosan samples. For these purposes, multiobjective optimization problems were formulated and solved using genetic algorithms implemented in Matlab®. The multiple optimal solutions represented by trade-offs between the two objectives are presented for each case.

The application of conventional flocculants always causes degenerative diseases, whereas natural polysaccharide (NPs)-based flocculants exhibit great potential, due to their biosafety. Considering material costs and sustainable development, NPs derived from waste have been extensively researched as a substitute for conventional flocculants, promoting the development of flocculation process toward safety, economy, and low-carbon direction. This review summarizes various waste polysaccharides (WPs) derived from ocean waste, agricultural waste, food waste, and invasive species. It then compares the treatment effects of typical WPs-based flocculants in water treatment. Flocculation mechanism of WPs-based flocculants was emphasized based on their respective structures and physicochemical properties. Moreover, flaws in WPs application have been noted, and strategies to deal with them have also been proposed. Benefiting from the environmental and economic benefits of WPs, the progress of using WPs-based flocculants is promising. However, some threats should be overcome, especially in terms of the stability and broad-spectrum applicability of WPs.
