Chitosan is a cationic polymer obtained by deacetylation of chitin, found abundantly in crustacean, insect, arthropod exoskeletons, and molluscs. The process of obtaining chitin by the chemical extraction method comprises the steps of deproteinization, demineralization, and discoloration. To obtain chitosan, the deacetylation of chitin is necessary. These polymers can also be extracted through the biological extraction method involving the use of microorganisms. Chitosan has biodegradable and biocompatible properties, being applied in the pharmaceutical, cosmetic, food, biomedical, chemical, and textile industries. Chitosan and its derivatives may be used in the form of gels, beads, membranes, films, and sponges, depending on their application. Polymer blending can also be performed to improve the mechanical properties of the bioproduct. This review aims to provide the latest information on existing methods for chitin and chitosan recovery from marine waste as well as their applications.

“…Competently, the qe cal for the pseudo-first-order (12.74 mg/g) was considerably more in line with the experimental value (11.9275 mg/g) than the pseudo-second-order. 48,49 The pseudo-first-order kinetic process indicates equilibrium between the liquid and solid phase for reversible reactions. At the same time, the pseudo-second-order kinetic model predicts that mass transfer is not the rate-limiting step but rather the adsorption mechanism.…”

The contamination of water bodies with harmful pollutants considers an aggravating global problem. The current research focuses on a developing efficient adsorbed for removing nitrate ions from aqueous solutions. The study proposed modified chitosan-zeolite composite beads to enhance the performance of the adsorption process. The zeolite was used to increase the surface area, and Zirconium was loaded on the beads to promote the selectivity for nitrate anions. The adsorption mechanism was assessed by characterizing the beads and sorbate adsorbed beads utilizing X-ray diffraction analysis (XRD), Fourier transform infrared spectroscopy (FTIR), Field Emission Scanning Electron Microscopy (FESEM), and analysis with an energy dispersive X-ray analyzer (EDX). The experiments were conducted in a batch system, and the effect of key parameters like contact time, initial nitrate anion concentration, and adsorbent dosage on the adsorption performance was investigated. The results demonstrated that the highest removal of nitrate ions was determined to be 95.42% at 0.2 g of Cs-Ze-Zr adsorbent with an initial concentration of 50 mg/L and a contact time of 120 minutes. The maximum adsorption capacity of the nitrate ions on the manufactured bead was 80.15 mg/g. In addition, among the Freundlich, Langmuir, and Temkin isotherms, the isotherm equilibrium data were consistent with a Freundlich isotherm model. The kinetic data for adsorption were satisfactorily fitted by a pseudo-first order. Subsequently, the results distinctly indicated that the proposed adsorbed (Cs-Ze-Zr) could be employed fruitfully in removing nitrate ions, demonstrated through the remarkable removal efficiency and adsorption capacity obtained in the study.

“…The standard value of BOD for raw POME is 25,000 to 65,714 mg/L. Due to the high regulation from the DOE, most of the mills in Malaysia and Indonesia do not fulfill this requirement [5;24] Jawad et al (2018) [25] found that the characteristics of raw POME at a palm oil mill in Seri Ulu Langat, Malaysia, consists of 10,843 mg of oil and grease per 1L of POME. Due to the high value of oil and grease, POME can form an oily layer on the river's water surface and deter light penetration into the water.…”

Indonesia and Malaysia are countries with the highest palm oil production globally. Indonesia is leading the list, followed by Malaysia and Thailand. Palm oil production generates countless benefits to the economy, environment, and society of the contributed countries. This industry provides high income and collection of methane gas for biogas generation and economy of the local community. However, despite the benefits, this industry has some difficulties, including treating the Palm Oil Mill Effluent (POME). POME contains a complex microbial structure and a high amount of oil, grease, and suspended solids. The existing treatment of POME consists of many drawbacks that lead to poor quality of the effluent and failure to meet the minimum requirement from the Department of Environment (DOE). Advance Oxidization Process (AOP), bio granulation, and ponding system are among the research that have been tried to treat POME. The local government still uses old-style treatment types such as Conventional Activated Sludge (CAS), ponding system, and anaerobic digester tank. This review paper presents a mini review of positive and negative consequences the palm oil industry as well as examine a bibliometric study towards the modern research development of the POME. This mini review concludes that the palm oil industry encourages the positive impact in economy, environment and social to the many parties especially country and local community. Besides that, the existing treatment of the POME have to be improved appropriate with the increment of the demand and era.
