# Where do Eggshells go?

**Where do Eggshells go?: Compost or food waste. Crush them first or they will still be recognisable next year.**

Food waste collection

Eggshell is calcium carbonate and breaks down very slowly in a heap, which is why whole halves survive a full composting cycle intact. Crushed to a powder they break down faster and add calcium. The claim that scattered shell deters slugs does not hold up in trials, though it does no harm. Food waste collections take them without any preparation at all. Where there is no local food waste collection they go in general waste, and the council list decides that.

## How to prepare it

1. Dry and crush them before adding to a compost heap.
2. Rinse if they are going to sit in a caddy in warm weather.

## What not to do

- Never expect whole shells to disappear in a heap; they will not.

> Kerbside collection rules genuinely vary by council and county, and local rules always win over general guidance. The reasoning above is what transfers — if your service differs, it will usually be for a reason described here.

## Other things that go to food waste collection

- [Food scraps and leftovers](https://atoneplace.net/where-does-it-go/food-waste/) — Food waste collection where you have one — it accepts cooked food, meat and dairy, unlike a home compost heap.
- [Teabags](https://atoneplace.net/where-does-it-go/teabags/) — Food waste or compost — but many bags are sealed with polypropylene, and that plastic mesh stays behind.
- [Cooking fat, lard and dripping](https://atoneplace.net/where-does-it-go/cooking-fat/) — Let it solidify, scrape it into the food waste or general bin. Never down the drain, at any temperature.
- [Bones](https://atoneplace.net/where-does-it-go/bones/) — Food waste collection if you have one. Never a home compost heap.
- [Coffee grounds](https://atoneplace.net/where-does-it-go/coffee-grounds/) — Compost heap or food waste. Good material in both, in moderation.
