Recycling of Chicken Egg Shells into Nanopowder: Synthesis, and its Properties

Abstract

Increase in unconventional resources of calcium (Ca +2 ) for fowls, aquaculture and native animals was improved. This work was planned to define the most polymorph of calcium carbonate (CaCO 3 ) that take place in the two types of chicken eggshells (local and imported type). In this research, the comparative analysis of calcium carbonate (CaCO 3 ) content was approved for nominated eggshells of native strain and imported chicken via Field Emission Scanning Electron Microscope (FESEM), Transmission Electron Microscope (TEM), Fourier-Transform Infrared Spectroscopy (FTIR) and Powder X-Ray Diffraction (PXRD) analysis. The results demonstrate that native and imported chicken eggshells comprise calcite morph that had shape between rhombohedral and spherical with distinguished pores distribution in the surface and crystallization size (31) nanometer for local chicken eggshells and (32) nanometer for import chicken eggshells respectively. The authors brief their results that local and import chicken eggshells had the top resources of calcium carbonate (CaCO 3 ).

Green Synthesis of Calcium/Iron-Layered Double Hydroxides-Sodium Alginate Nanoadsorbent as Reactive Barrier for Antibiotic Amoxicillin Removal from Groundwater

“…The previous research focused on using wastes, recycled, and by-product materials in PRB technology to enhance their activity in using sustainable (green) concepts, such as activated neem leaves [19], coir pith [20], recycled concrete [21], municipal composts, leaf composts, wood chips, limestone, silica sand [22], and peat and sawdust [23] in treating water contaminated with pollutants. Eggs represent as one of the most ingredient used in variety of products resulting in several daily tons of eggshell which is ranked as the 15th major food industry pollution problem by the EPA, and most of these quantities are accumulated on site or disposed annually as waste in landfills without any pretreatment and become as an organic environmental pollution source [24]. Furthermore, with increasing urgent recently to converting worthwhile waste into useful commodities for sustainable development by recycle, reuse for manufacturing high-value products, managing agricultural wastes is vital and a crucial strategy [25].…”
