With care

Yes, with care. Bread breaks down quickly, but it attracts rodents and molds fast. Add small amounts, torn up and buried in the center of an enclosed pile, or put it in bokashi.

How to compost bread

Tear stale bread into small pieces and bury it 8–12 in (20–30 cm) deep in the center of the pile, then cover with browns. Keep it to the odd crust or slice, not whole loaves. A closed bin with a solid or mesh base is safer than an open heap.

Send larger amounts to bokashi or municipal food-scrap collection. Bread with butter or spreads counts as cooked food.

What goes wrong

Bread on the surface is an open invitation to rats, mice and birds. If you see burrows or droppings, stop adding food scraps and switch to bokashi or a rodent-proof bin. Soggy bread can form a moldy clump, so break it up and mix it in.

Worm bins and bokashi

Worm bin: Small amounts of stale bread, moistened and buried, are fine, but too much sours the bin.

Bokashi: Bokashi is the best home for bread and baked goods; it ferments them quickly with no pest risk.

This counts as a green. Adding a lot of it? Check the balance with the compost mix calculator.

Frequently asked questions

Can you compost moldy bread?

Yes. Mold doesn't make bread any worse for compost. The same rodent caution applies: small amounts, buried deep.

Does bread attract rats to compost?

It can. Bread is high-energy food, so keep it buried, use a closed bin with a mesh or solid base, or divert it to bokashi.

Is bread a green or a brown?

It's usually counted as a green, since it's food waste. In practice it's a small addition that won't change your balance much.
