“…The temperature of calcination could range from 500 to 1000°C depending on the application. It has been reported that at 900°C, the CaCO 3 undergoes complete conversion into CaO [21]. The material produced after calcination is the sorbent material, which is placed in a desiccator to curtail the chances of coming in contact with humidity and carbon dioxide in the air.…”

“…This crystallite size decrease can be ascribed to the exothermic natures of the calcination process. However, the lower intensity peaks for calcined eggshell and oyster shell could be related to the reduction in the crystallite size [21,23]. Hence, the changes in the XRD pattern as a result of calcination are because of the release of carbon dioxide from the decomposition of CaCO 3 into CaO.…”

This review aims to explore the application of natural and renewable bioceramics such as eggshell and seashells in carbon dioxide (CO 2) capture from power plant flue gas. CO 2 capture, utilisation and storage (CCUS) is considered a means to deliver low carbon energy, decarbonising industries, power plants and facilitates the net removal of CO 2 from the atmosphere. The stages involved include CO 2 capture, transport of the captured CO 2 , utilisation and secure storage of the captured CO 2. This chapter reports the use of eggshell and seashells biomaterials as an adsorbent to separate CO 2 from other gases generated by power plants and industrial processes. The capture of carbon dioxide by adsorption is based on the ability of a material to preferentially adsorb or carbonate CO 2 over other gases. In light of this, calcined eggshell and seashells biomaterial rich in calcium carbonate from which calcium oxide (94%) can be obtained have demonstrated a strong affinity for CO 2. These biomaterials are abundant and low-cost alternative to zeolite, activated carbon and molecular sieve carbon. The mechanism of CO 2 capture by eggshell and seashells derived CaO adsorbent comprises of a series of carbonation-calcination reactions (CCR): calcium oxide (CaO) reacts with CO 2 resulting in calcium carbonate (CaCO 3), which releases pure CO 2 stream upon calcinations for sequestration or utilisation, and as a consequence, the biomaterial is regenerated. Findings reveal that these biomaterials can hold up to eight times its own weight of CO 2 from flue gas stream. It was also found that the combination of 2 M acetic acid and water pretreatment improved the reactivity and capture capacity of the biomaterial for successive regeneration over four cycle's usage. Unlike activated carbon, these biomaterials are considered stable for hightemperature adsorption through carbonation.

“…The high intensity and sharp peaks of the calcined waste shells show that they are well crystallized structure materials. The peaks of CaO, at calcination temperatures of 900ºC and 1000ºC for 2θ values at about 32, 38, 54, 64 and 68 correspond to (111), (200), (220), (311) and (222) planes, respectively (Buasri et al, 2015;Laskar et al, 2018). The loss of ignition (LOI) is due to the partial transformation from calcite to CaO releasing CO 2 .…”

This mini-review reports curbing waste shells (i.e. seashells, eggshells, snail shells, etc.), environmental health issues and liabilities by using them as material for heterogenous catalysts, blended cement manufacture, concrete aggregate, ceramics and plastics additives, biofilter medium and biomedical applications. The traditional materials used in the manufacture of these products could be relatively cheap; however, there are considerable environmental issues (i.e., ecological damage, disruption of eco-system and air contamination) as well as intense energy consumption associated with the exploitation of depleting natural resources. Waste shells are a renewable and cheap alternative, and will simultaneously decrease manufacturing cost while reducing their burden on the environment. This paper emphasizes environmental sustainability by summarizing articles published on various applications of waste shell-derived biomaterials. The properties of waste shell-derived biomaterials are presented and discussed. The materials’ properties suggest they are similar to limestone and their biological–natural origin and the high calcium carbonate content with a trace amount of other mineral elements makes them highly favorable for cement production, heterogenous catalysts and hydroxyapatite manufacture for biomedical and wastewater treatment applications. The purpose of this work is to offer new perspectives and direction for future research on waste shell-derived biomaterials while existing areas of applications demanding scale up are highlighted.

“…The content of FAME in biodiesel samples was analyzed by the gas chromatographymass spectrometry (GC-MS, QP2010 Plus, Shimadzu Corporation, Japan) equipped with a flame ionization detector and a capillary GC column (DB-WAX, Carbowax 20M, 30 m × 0.32 mm × 0.25 μm) using inner standard method as described by Buasri et al [15]. The yield of biodiesel was calculated by dividing the weight of biodiesel with the weight of oil and multiplying the resulting number by 100 (Equation (1)).…”

The goal of this research was to test barium chloride (BaCl2) impregnated calcined razor clam shell as a solid catalyst for transesterification of rubber seed oil (RSO) in a packed bed reactor (PBR). The waste razor clam shells were crushed, ground, and calcined at 900 °C in a furnace for 2 h to derive calcium oxide (CaO) particles. Subsequently, the calcined shells were impregnated with BaCl2 by wet impregnation method and recalcined at 300 °C for 2 h. The synthesized catalyst was characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), energy dispersive spectrometer (EDS), Brunauer-Emmett-Teller (BET) surface area, and basic strength measurements. The effects of various parameters such as residence time, reaction temperature, methanol/oil molar ratio, and catalyst bed length on the yield of fatty acid methyl ester (FAME) were determined. The BaCl2/CaO catalyst exhibited much higher catalytic activity and stability than CaO catalyst influenced by the basicity of the doped catalyst. The maximum fatty acid methyl ester yield was 98.7 % under optimum conditions (residence time 2.0 h, reaction temperature 60 °C, methanol/oil molar ratio 12:1, and catalyst bed length 200 mm). After 6 consecutive reactions without any treatment, fatty acid methyl ester yield reduced to 83.1 %. The option of using waste razor clam shell for the production of transesterification catalysts could have economic benefits to the aquaculture and food industries.
