“…Beside CaCO 3 diffraction peaks, Ca(OH) 2 and CaO peaks were observed on the three samples. Ca(OH) 2 diffraction peaks were present dominantly due to reactive moisture adsorption (Tangboriboon et al, 2012). This might be caused by sample contact to air moisture.…”

Calcium oxide (CaO) nanoparticles have been successfully synthesized from duck eggshells using ball milling method followed by simple calcination at 700 °C for 7 hours. The observation on the morphology, size and shape of the particles of the eggshells powder was conducted through scanning electron microscope (SEM). The milling time was varied, i.e. 2, 6, 10, and 20 hours to observe the difference in the size of the produced particle. SEM images show that the smallest average particle diameter is 520 nm, achieved by 20 hours of milling. When the particles were calcined, the average diameter was further reduced to 394 nm. The X-ray diffraction (XRD) analysis shows that the resulting particles contain calcium oxide, calcium hydroxide, and calcium carbonate.

“…Eggshell wastes primarily contain magnesium and calcium carbonates, and protein . The calcium oxide obtained from calcined eggshells could be potentially used in various applications such as in the starting materials for dielectrics such as CaSiO 3 , CaTiO 3 , CaAl 2 O 4 , and also in gypsum (CaSO 4 ) or as bio‐catalysts . Given the purity of eggshell powder obtained for this study (the heavy metal content was extremely low); eggshells were considered as a substitute for limestone for use in the production of both clear and green container glass, in this study.…”

For energy saving and CO2 emissions reduction, in addition to extending the range of suitable raw material sources for glass manufacture, compositional reformulation, and alternative raw materials have been studied in the context of industrial container and float‐type soda‐lime‐silica (SLS) glasses. Lithium, potassium, and boron were applied to modify benchmark glass compositions. Reformulation impacts on key glass properties including the viscosity‐temperature relationship, thermal expansion, liquidus temperature, forming behavior and color. Compared to the benchmark glass, representative of commercial SLS glasses, melting temperatures (taken as temperatures corresponding to log (viscosity/dPa·s) = 2) of reformulated glasses are reduced by 11°C‐55°C. Investigation of four industrial by‐products (seashell waste, eggshell waste, biomass ash, and rice husk ash), and their potential suitability as alternative glass batch raw materials, was also conducted. Seashell waste and biomass ash were successfully introduced into representative green glass formulations.

“…The eggshells were washed, sundried and thereafter crushed and ground to obtain fine powder. Some of the eggshells powder was calcined at 700ºC for 2 h (Tangboriboon et al, 2012;Buasri et al, 2013). Eggshells calcination was done purposely in order to transform calcium carbonate (CaCO3) from un-calcined eggshells into lime or calcium oxide (CaO).…”

“…The use of eggshells, which is readily available in hotels, baking/confectionary and hatching industries (King'ori, 2011), not only provides a cheap avenue to increased utilization of lignocellulosic materials in biogas production, but also helps in waste management and hence promote both the public and environmental health. This is because egg waste can cause odours due to microbial action and can also change the quality of soil (Tangboriboon et al, 2012).…”

In this study, pretreatment of banana pulp using eggshells in both calcined and un-calcined forms to examine the extent of hydrolysis was conducted. Reactor C O containing banana pulp and inoculum but with no eggshells added was used as the control, while reactors C 1 , C 2 , C 3 , C 4 , and C 5 containing banana pulp and inoculum were spiked with 1, 3, 5, 7, and 9 g of un-calcined eggshells and calcined eggshells, for experiment 1 and 2, respectively. Anaerobic digestion was carried out at mesophilic temperature (35°C) for a period of 20 days. Digester C 3 with 5 g of calcined eggshells gave the largest cumulative biogas yield of 2343 mL with 62% CH 4 , followed by digester C 5 with 9 g of un-calcined eggshells which gave 2032 mL with 51.9% CH 4 . The least biogas yield of 10 mL was obtained in digester C 5 with 9 g of calcined eggshells additive.
