You can also ignore the usual local council advice not to compost
citrus peel, onion skin and eggshells because they don't decompose. It's
nonsense.

I agree.

I totally agree with you about citrus peel, but eggshells just sit there.
I've pulled them out from the bottom after being in the composter for a
couple of years!.

Yes, they will, but chuck them on anyway! Just crumble them when you
use the compost.

The things that I compost that do last for ever are (sea) shells, like
mussel, oyster, scallop or winkle. But I chuck them on my traditional
heap anyway. Avocado stones, peach/nectarine/plum stones, the harder
nut shells etc. take some years, but they can be left to do that in the
soil. I sieve them out for making potting compost, but not for spreading
on the garden.

The point is that all of the above turn into things that are no more
harmful than small stones - and eggshells are more like limestone sand.
If you have acid soil, they will be useful for that.
