Eggshells (ground up) are good for vericomposting. As I alluded to above, soil chemistry is a web, with everything interacting. Decreasing the particle size to something close to fine powder will increase the mineralization rate in soils with active microbiota. It is considered that calcium carbonate in the eggshells changes into calcium oxide at approximately 800 C˚ [10] by arc discharge, as shown in equation 3.
