Description

<jats:p>In Brazil, the food industry generates every year huge amounts of avian eggshell waste, and a critical question is to find an adequate use for this waste. The aim of this work is to determine the chemical, mineralogical and physical characteristics of a nonprocessed avian eggshell waste sample, as well as to investigate its use in wall tile paste. The sample was analyzed regarding to chemical composition, X-ray diffraction, morphology, particle size analysis, density, organic matter, soluble salts, and thermal analysis. The results indicated that the eggshell waste sample rich in CaCO3 can be used as an alternative raw material in the production of wall tile materials.</jats:p>
