i decided against composting my eggshells at the community compost. i wasn't ever really sure those kids were doing it right...
should i just eat them?
i'm thinking i could microwave them to kill whatever's left (they've been left frozen.) and then mash them up and add them to my smoothies.
i need to do more research than this...
the other option, i'm thinking, is to leave them outside in a park. that might sound gross at first. but, the calcium takes a long time to breakdown, which is the reason it's maybe not the best thing for actual compost. so, you want to put them in places where the soil is more continually utilized, so they can replenish the soil as the calcium comes out.
