Valorization of Eggshell Waste into Supported Copper Catalysts for Partial Oxidation of Methane

Seven billion kilograms of chicken eggshells are disposed of every year. Eggshell-supported copper catalysts for partial oxidation of methane for the first time. CuO along with CaO activates methane and converts methane into value-added chemicals including C2–C6 hydrocarbons. Excellent recyclabilities were obtained. Value addition of eggshells can provide additional revenue to poultry producers and minimize waste disposal problems.
