The Impact

Chitosan is natural polysaccharides which is nontoxic, biodegradable, and biocompatible and have many advantages in various kinds of fields including health, food, agriculture, and industry. Chitosan usually take long time to extract by conventional method for deacetylation process of chitin. Raw material for chitosan can be found in shrimp shell waste. Chitosan manufactures usually need high temperatures and chemicals in large quantities and it takes much time and consumes a lot of energy where will give bad effect to the environment. Recently microwave irradiation as nonconventional energy sources is widely used in chemical reactions. To reduce the impact of environmental pollution due to excessive use of chemical treatment, the objective of this work is processing chitosan under microwave irradiation. Expected production of chitosan with the same mass requires fewer chemicals than conventional heating. In particular, the study will examine the effect of making the chitosan and adding chemicals, reaction time and operating temperature and degree of deacetylation in chitosan with conventional heating methods that the results will be compared using a microwave. In this research will be developed to the design and fabrication of prototype scale extractor for manufacturing chitosan from shrimp shell waste after optimum results obtained from the research laboratory scale. From the research we can conclude that microwave will speed up reaction time. FTIR also showed functional group of chitosan formed from microwave irradiation have same results.  Keywords: chitosan, shrimp shells, microwave

Better Than

Chitin and Chitosan obtained from the crustaceans are having more biological value such as physiological compatibility, non-toxicity, bio digestibility, adsorption and chelating capacity. These biological values of chitosan depend on the quality parameters which are directly related to the source of the raw material. In this study, three commercially available crustacean shell waste such as shrimp, crab and squilla were used for the extraction of chitin and chitosan. The chemical treatment of demineralization, deproteinization and deacetylation were used for the production of chitosan. The viscosity quality parameter of the shrimp chitosan (5300cPs) was better than the crab and squilla chitosan. It is due the high solubility (97.65%) of the shrimp chitosan in 1% acetic acid. The degree of deacetylation of the shrimp chitosan (81.24%) directly relates the solubility of the chitosan. The chitosan with these quality parameters considered to be the excellent biological value. The yield of shrimp chitosan (15.4%) was also more when compare to crab and squilla chitosan. These result showed that utilisation of shrimp shell waste for the production of chitin and chitosan will give more economical and biological value along with reduction of environmental pollution.

Freshwater Consumption

The conservation and proper management of natural resources constitute one of the main objectives of the 2030 Agenda for Sustainable Development designed by the Member States of the United Nations. In this work, a hybrid strategy based on process integration is proposed to minimize freshwater consumption while reusing wastewater. As a novelty, the strategy included a heuristic approach for identifying the minimum consumption of freshwater with a preliminary design of the water network, considering the concept of reuse and multiple pollutants. Then, mathematical programming techniques were applied to evaluate the possibilities of regeneration of the source streams through the inclusion of intercept units and establish the optimal design of the network. This strategy was used in the shrimp shell waste process to obtain chitosan, where a minimum freshwater consumption of 277 t/h was identified, with a reuse strategy and an optimal value of US $5.5 million for the design of the water network.

Feed is still one of the problems in aquaculture because it takes about 70% of operational costs. High prices is caused by imported raw materials for feed production. One possible effort to overcome this problem is to find alternative local raw materials to replace imported fish meal. The purpose of this study was to examine the proximate content of shrimp shell wastes from processing shrimp crackers (Paneus sp.) to be used as shrimp flour. Samples were colledted three times in a month, at the beginning, middle and end of the month. The waste of the heads, shells and tails of the shrimp were turned into flour for laboratory testing through proximate analysis. The data were tabulated using the Microsoft Excel softwareand then analyzed descriptively by comparing the nutrient content of shrimp waste flour with the feed requirements of mariculture. The results showed that shrimp shell flour contained protein, fat, carbohydrates and ash content of around 27.4%, 2.07%, 14.84% and 47.27%. while the resulting randemen ranged from 81.75%. Therefore, shrimp shell flour can be used as an alternative raw material for preparing marine fish feed.

Value Added Products

Chitin is the most abundant renewable nitrogenous material on earth and is accessible to humans in the form of crustacean shell waste. Such waste has been severely underutilized, resulting in both resource wastage and disposal issues. Upcycling chitin-containing waste into value-added products is an attractive solution. However, the direct conversion of crustacean shell waste-derived chitin into a wide spectrum of nitrogen-containing chemicals (NCCs) is challenging via conventional catalytic processes. To address this challenge, in this study, we developed an integrated biorefinery process to upgrade shell waste-derived chitin into two aromatic NCCs that currently cannot be synthesized from chitin via any chemical process (tyrosine andl-DOPA). The process involves a pretreatment of chitin-containing shell waste and an enzymatic/fermentative bioprocess using metabolically engineeredEscherichia coli. The pretreatment step achieved an almost 100% recovery and partial depolymerization of chitin from shrimp shell waste (SSW), thereby offering water-soluble chitin hydrolysates for the downstream microbial process under mild conditions. The engineeredE. colistrains produced 0.91 g/L tyrosine or 0.41 g/Ll-DOPA from 22.5 g/L unpurified SSW-derived chitin hydrolysates, demonstrating the feasibility of upcycling renewable chitin-containing waste into value-added NCCs via this integrated biorefinery, which bypassed the Haber–Bosch process in providing a nitrogen source.

Mixtures comprising water-soluble chitosan (WSC), agar and different concentrations of sodium lauryl sulphate (SLS) were used to synthesize capsule films. The concentration of agar was fixed at 0.02 %, whereas the concentration (v/v) of SLS varied (0, 0.02, 0.04, 0.06 and 0.08 %). Shrimp shell waste was subjected to demineralization, deproteination and deacetylation to obtain chitosan. The chitosan thus obtained was depolymerized to produce water-soluble chitosan (WSC). Fourier-Transform infrared (FTIR) baseline method was used for calculating the degree of deacetylation of chitosan. FTIR spectra of the obtained capsule film exhibited vibrations of its constituent molecules, namely agar, chitosan and SLS. The elasticity of the film matrix increased with SLS concentrations. In swelling tests conducted using water and 0.1 N HCl, the highest swelling values, 123.74 and 235.87 %, respectively were observed in the capsule film containing 0.08 % SLS in the 10th min. The capsule film containing 0.08 % SLS was degraded (broken) in water and 0.1 N HCl in the 10th and 30th min, respectively. The results indicated that a capsule film containing 0.08% SLS was the most eligible film for commercial use.
