“…These results were in line with the previous research by Arvela-Mäki and co-workers[24]. However, it was seen that peak Ca(OH)2 at the 800°C temperature calcination catalyst decreased[6]. According to XRD and FTIR data, the catalyst CaO and Fe2O3 are successful in production.…”

Methylene orange (MO) is a toxic fabric dye to the environment and health. Therefore, some actions are needed to overcome this problem. The advanced oxidation process (AOPs), especially Fenton by hydrogen peroxide (H2O2) and CaO/Fe2O3, is a powerful method to be implemented. In this experiment, the CaO/Fe2O3 was prepared by impregnation using CaO derived from chicken eggshell waste and Fe(NO3)3⸳9H2O powder with calcination temperature variations of 600, 700, and 800°C. Then, the characterization of materials was identified by Fourier Transform Infrared (FTIR), X-ray diffractometer (XRD), scanning electron microscope (SEM), and electron dispersive spectroscopy (EDS), followed by a visual observation decolorization test. Using FTIR and XRD, CaO has been successfully obtained through the calcination process. Fe2O3 was also detected, indicating impregnated into CaO support. The particle size ranges from 37–48 mm, appearing irregular in shape. Finally, the fastest decolorization of MO resulted in CaO/Fe2O3 with 800°C of calcination temperature. These results indicated that CaO/Fe2O3 nanocomposite catalyst is the potential to reduce liquid pollutants and utilize a waste resource.

“…The heterogeneous Fenton catalyst becomes the solution to this problem that is reusable and applicable in the broader pH range. However, the catalytic activity is too low, causing insufficient practical use [6]. Therefore, it is necessary to do further research to show that the catalytic activity of Fenton heterogeneous increases.…”

“…Wibowo et al investigated the synthesis of a BC@Fenton catalyst, where a BC hydrogel was dipped into Fe 2+ and Fe 3+ (1:2) precursor solutions, followed by immersion into ammonia solution overnight. The particle size of the heterogeneous catalyst was greatly reduced by BC, and as a consequence, the catalytic efficiency of the BC@Fenton catalyst in the degradation of methylene blue was enhanced [ 179 ]. Song et al investigated BC as a supporting matrix for the synthesis of copper and nickel nanoparticles and evaluated their catalytic efficiency against nitrophenol reduction [ 180 ].…”

Bacterial cellulose (BC), also termed bio-cellulose, has been recognized as a biomaterial of vital importance, thanks to its impressive structural features, diverse synthesis routes, high thermomechanical properties, and its ability to combine with multiple additives to form composites for a wide range of applications in diversified areas. Its purity, nontoxicity, and better physico-mechanical features than plant cellulose (PC) make it a better choice for biological applications. However, a major issue with the use of BC instead of PC for various applications is its high production costs, mainly caused by the use of expensive components in the chemically defined media, such as Hestrin–Schramm (HS) medium. Furthermore, the low yield of BC-producing bacteria indirectly accounts for the high cost of BC-based products. Over the last couple of decades, extensive efforts have been devoted to the exploration of low-cost carbon sources for BC production, besides identifying efficient bacterial strains as well as developing engineered strains, developing advanced reactors, and optimizing the culturing conditions for the high yield and productivity of BC, with the aim to minimize its production cost. Considering the applications, BC has attracted attention in highly diversified areas, such as medical, pharmaceutics, textile, cosmetics, food, environmental, and industrial sectors. This review is focused on overviewing the cost-effective synthesis routes for BC production, along with its noteworthy applications in the food and environmental sectors. We have made a comprehensive review of recent papers regarding the cost-effective production and applications of BC in the food and environmental sectors. This review provides the basic knowledge and understanding for cost-effective and scaleup of BC production by discussing the techno-economic analysis of BC production, BC market, and commercialization of BC products. It explores BC applications as food additives as its functionalization to minimize different environmental hazards, such as air contaminants and water pollutants.
