If the eggshell membrane, and the eggshell itself, were composted after the eggshell and membrane were exposed to the air – would the creation of soil through composting capture the carbon in the soil? How long does the eggshell have to be exposed?

If successfully developed, this could help a little bit, but the weight of an eggshell membrane is a tiny percentage of the total egg weight. Globally, humans already emit almost 30 gigatons of CO2 annually (~8 Gt carbon equivalent). So you can imagine how much membrane would need to be carbon-infused AND permanently sequestered to make much difference.

Wizbot: The concept for a commercial-scale operation would be to extract the carbon dioxide and use it in such a way that carbon emissions are greatly reduced or eliminated. For individuals who air out their eggshells and then discard them, the variable woud be thel disposal method.

Would all the co2 not go right back into the air when the membranes decomposed?

If not, please provide some figures. How much carbon would be absorbed if x% of eggs were exposed to the atmopshere?
