Can you recycle pizza boxes?

🌱 CompostGreasy box → green compost cart; a clean, grease-free box → blue recycling.

The old rule was 'grease ruins recycling,' and it's half true. A greasy or food-soiled pizza box goes in the green organics/compost cart in LA County — it's food-soiled paper. A clean, grease-free box (or the clean top half) can be flattened and recycled.

The grease line

Tear the box in two: put the greasy, cheesy bottom in the green compost cart (exactly what organics collection is for), and recycle the clean top in the blue cart. If the whole thing is greasy, the whole thing composts.

Leftover crusts & toppings

Food scraps left in the box — crusts, that one sad pepperoni — also go in the green compost cart, not the trash.

Don't

Don't put a grease-soaked box in the blue recycling cart; the oil contaminates the paper bale. And don't landfill a compostable box if you have green-cart service.

Pizza Boxes — quick FAQ

Can you put pizza boxes in the recycling bin?
Only if they're clean and grease-free. A greasy pizza box goes in the green compost/organics cart instead — grease contaminates recycling.
Why are pizza boxes not recyclable when greasy?
Grease and cheese soak into the cardboard fibers and can't be separated during paper recycling, so a greasy box is composted rather than recycled.
What do you do with old pizza boxes?
Compost the greasy parts (green cart), recycle the clean parts (blue cart), and put any leftover food scraps in the green cart too.
How do I get rid of pizza boxes?
Flatten them — clean cardboard to the blue recycling cart, greasy cardboard to the green compost cart.
