Are egg cartons recyclable?
It depends
Depends entirely which of the three kinds you have. Grey moulded pulp: yes, or compost it. Clear plastic: usually, but check. Foam: no.
What you need to do
- Identify the material first — pulp, clear plastic or foam
- Empty, clean and dry. A carton used to hold cracked eggs is contaminated and is no longer recyclable
- Check your programme specifically for clear plastic; this is the one that genuinely varies
- Keep foam out of the bin regardless
Why the answer isn't simple
Three different questions hide inside "is this recyclable?" — and most pages only answer one of them.
Is the material recyclable? partial
What the stuff is made of, in principle.
Three completely different materials are sold as the same product, and the packaging gives you no reason to think of them separately. Grey moulded pulp is recycled paper fibre — often already at the end of its recycling life, since the fibres are short. Clear cartons are usually PET, the same plastic as a drinks bottle. Foam cartons are expanded polystyrene. The right answer changes with each, so the first step is identifying which one is in your hand.

Will a sorting facility recover it? partial
What actually happens on the line.
Pulp cartons run with paper without difficulty. Clear PET cartons are more marginal than their material suggests — they are thin-walled and awkwardly shaped, so whether they get recovered depends on the individual processor rather than on the plastic. Foam fails for the same reasons foam always fails: too light to sort, and it shatters on the line.
Will your curbside program take it? varies
Local policy, which is where answers diverge.
Programmes broadly agree on the ends and disagree in the middle. Pulp cartons are widely accepted; foam is widely refused. Clear plastic is the coin-flip — Cuyahoga County says it depends on your processor, while Omaha accepts clear plastic outright and routes foam into a separate hard-to-recycle bag programme instead.

Where else it can go
Compost the pulp ones
Moulded pulp composts quickly, especially torn up. This is often the better route anyway — the fibres are short enough that a paper mill gains little from them.
Pulp only. Foam and plastic do not compost.
Give them back
Farmers' market egg sellers and anyone keeping backyard hens will usually take clean cartons of any type and reuse them directly.
Clean and undamaged only.
Seed starting
Pulp cartons work as seedling trays and can be planted straight into the ground.
Common mistakes
- Treating all egg cartons as one thing because they are all the same shape
- Putting cracked eggs back in the carton and then recycling it
- Assuming a foam carton is fine because the pulp version is
