Eggshell and protein membrane separation

Patent Granted Eggshell and Protein Membrane Separation is a recycling process. Nearly 30% of the eggs consumed each year are broken and processed or powdered into foods such as cakes, mixes, mayonnaise, noodles and fast foods.[1] The US food industry generates 150,000 tons of shell waste a year.[2] The disposal methods for waste eggshells are 26.6% as fertilizer, 21.1% as animal feed ingredients, 26.3% discarded in municipal dumps, and 15.8% used in other ways.[3] Many landfills are unwilling to take the waste because the shells and the attached membrane attract vermin. Together the calcium carbonate eggshell and protein-rich membrane have no value or use.
