Eggshells wastes are produced in huge amounts worldwide. The recycling or valorization of this waste, which otherwise is usually disposed in landfills, represents an opportunity within a circular economy perspective. In the present work, the potential of chicken eggshell waste to produce calcitic lime was explored. After collection from an industry supplier, the waste was thoroughly characterized for its mineralogical, chemical, and thermal properties. The material was calcined at 1000 °C, and… Expand
Valorization of Eggshell Biowaste for Sustainable Environmental Remediation

A literature review on adding value to solid residues: egg shells.
The production of chicken eggs on an industrial level leads to a considerable quantity of shell residue, which is considered as a waste or is used as a complement in agriculture. In general, eggExpand
Waste shells of mollusk and egg as biodiesel production catalysts.
The solid oxide catalysts derived from waste shells of egg, golden apple snail, and meretrix venus were employed to produce biodiesel from transesterification of palm olein oil and showed high biodiesel production activity over 90% fatty acid methyl ester (FAME) in 2h. Expand
