“…Millions of kilograms of waste chicken eggshells produced annually in the US pose a serious challenge to the environment . The decomposing organic components leading to the emission of repugnant smell (H 2 S) and the creation of an enabling environment for invasion by potential diseases causing pathogens as well as unattractive piles of residue are some of the issues with waste eggshells . Alternative use of egg shell as components in structural materials will help in mitigating these challenges whiles providing for other societal needs.…”

ABSTRACT:The need for bio-based polymers as substitutes to recalcitrant petroleum sourced plastics is ever growing, because of increase in demand globally. Eggshell nanopowder (ENP) prepared using mechanical attrition and ultrasound irradiation was used to infuse a bio-based polymer [Super Sap 100/1000 epoxy (SSE)] for possible enhancement of its mechanical properties. The ENP, neat SSE and SSE/ENP composites were characterized using X-ray Diffraction, Transmission Electron Microscopy (TEM), Energy dispersive spectroscopy (EDS), Scanning Electron Microscopy, Thermogravimetic Analysis (TGA), Dynamic Mechanical Analysis (DMA), Thermomechanical Analysis (TMA) and flexure analysis. TEM and EDS analysis showed evidence of ENP in the SSE matrix whiles DMA and TMA analysis revealed significant improvements (7-22%) in the storage moduli and (3-17%) in coefficient of thermal expansion (CTE) respectively. Also, major delay in 5% decomposition temperatures and increases in char yields were observed in TGA analysis. The flexure strength, modulus, and toughness significantly improved by 6-31%, 11-37%, and 10-36%, respectively. Microstructure of fractured surfaces showed deflected crack paths which contributed to improve toughness. V C 2015 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 43124.

“…From 470°C to 800°C, the sample continues losing weight, showing several very small peaks in the DTA curve. Some authors have attributed similar behaviours of these ashes to the reactions of water loss, combustion of the not burnt elements, and carbonate decomposition [25]. Due to the characteristics of the process, from which this residual material originates, and to the macroscopic observations, it is probable that the waste still contains material which has not been burnt.…”

Biomass-energy processes are those used to obtain energy by the burning or biochemical converting of any organic matter to be used for fuel. In recent years, some materials used as a source for biomass energy have been obtained from the discards of agricultural activities. These include wood, sawdust, corn, sugarcane and rice husks, among others. The processes for converting biomass into energy are numerous. The most commonly used are combustion, co-firing process and pyrolysis. The residual endproducts obtained from these processes are highly dependent on the process conditions, especially temperature, pressure and atmosphere. Char and ashes are the most commonly obtained materials. The objective of this work is to analyse the feasibility of reusing these discards of biomass-energy processes, as additions in clay mixtures for the production of ceramic materials for civil construction. For this purpose, charcoal and ashes obtained from various biomasses have been characterized by SEM, EDS, DTA-TGA, XRD, etc. These results, and the determination of the theoretical sintering temperatures by the use of ternary diagrams, lead to the establishment of the feasibility of using these discards in current ceramic industry processes. Charcoal and ashes from sunflower husks, brewery waste and pine sawdust are the materials studied.
