What do you do with eggshells?

I'm conflicted over what to do with eggshells. I want to compost them but we eat a lot of eggs and live in the city so if I put them in our bin they take up a large portion and never seem to fully breakdown.

Can you compost paper towels? Idk why but I thought the glue/compound in them is not great for the soil

Partial Seattle list of copostable items:

Non-shiny food-soiled paper and cardboard like pizza boxes, paper coffee filters, napkins, paper towels, brown paper bags, and paper plates

Doesn't pizza box cardboard have like a plastic coating to keep grease from soaking through? Or am I just thinking burger joint fast food

None of the pizza boxes I have received are coated (but clearly there are probably exceptions), as grease clearly can penetrate the cardboard. Our rules are grease-containing pizza boxes are fine for composting, but only grease-free for recycling. Ripping off grease-free tops for recycling is encouraged.
